Are the data sources in the report using the 64-bit SQL instance that has the linked server configured. Also, just curious if you re able to natively connect to the Oracle database from SQLPlus on the m c in question.
Tuesday, March 25, 2008 - 5 35 59 PM - dbajohnny Back To Top 780. Were you able to complete the steps outlined in this tip successfully. Can you successfully set up and query the linked server from within SSMS, not BIDS. Is it compulsory to do set up linked server from SSMS. Without that linked server can t we connect using BIDS.
Are you getting a specific error in BIDS. Test connection failed because of an error in initializing provider. 1 provider is not registered on the local machine. I used different providers also getting same error. Are you running BIDS from the server you installed the driver on or are you doing your BIDS work from a different workstation server laptop. If so, you ll need to install Oracle on that instance and configure a connection from there during your build before you deploy it.
I am running BIDS from different m c. Here i installed client s w of Oracle. pl can you give steps. How can i configure the connection.

How-To Install a 32-bit Program in 64-bit Mac OS X 10. Author Mike Adams 12 09 2009. So, you have yourself the fancy new Apple operating system, Snow Leopard, and you also bought yourself a few software titles. You rushed home and installed that shiny new OS on your Mac and it runs like a dream. You even opened up more of your hard drive after the installation.
Good thing you just bought some software to fill up that space. So you pop in your Adobe Acrobat Pro 9 to install it, and you are greeted with the message, Adobe Acrobat 9 Pro can t be installed on this computer. Make sure your system meets the requirements. You have a relatively new MacBook Pro so this must be some sort of mistake. Well, it is kind of. What might be happening in this case is that you could have your new OS set up to run in 64-bit mode. How is this a mistake. Adobe, and many companies, have programmed their installers to run in 32-bit mode since before 10.
6, this was THE most common method of running your operating systemand again, you might have your OS set to run in 64-bit mode. This really doesn t help your situation though. Adobe has patches for its programs in place for this if you already have your programs installed, you know, so that you can continue to run their programs in 64-bit mode. So how can you install your program. Well first, you need to see if this is really the problem.
To do this, just. Thanks for dropping by UC Davis Bookstore TechTalk. Head to the Apple Menu located at the top left of your desktop and click on it. Next click on the option, About this Mac. Now, you should see an option for More infoclick on this to take you to System Profiler. Scroll down on the left hand pane until you see Software. Click on this and you will see an overview of your System Software. Look for 64-bit Kernel and Extensions and it should either have yes or no.
If it says nothen that means that your OS is already running in 32-bit mode. If it says yesthen that means that you are indeed running in 64-bit mode. If you are running in 64-bit mode, you will have to force your machine to run in 32-bit mode while you install and patch. To do this, you will need to. Restart the computer and hold down the 3 and 2 keys on boot up. This will send your OS into 32-bit mode until you restart. Double check to make sure that you are indeed in 32-bit mode after this using the steps above.
Once you have verified that you are in 32-bit mode, just install and patch the program. Restart your computer and your OS should automatically default back to 64-bit mode. I just wanted to let everyone know that there is a nice short article about 32-bit software running on 64-bit Windows machines I found. com 2009 05 27 simple-facts-about-64-bit-computing to check it out.

HP and other OEMs are planning to increase the number of 64-bit choices in the volume server space. HP Adds to 64-Bit Computing Options. The dramatic changes in the 64-bit computing landscape over the past few weeks have left users in the volume server space with something they had little of before last month choice.of Palo Alto, Calif.
Hewlett-Packard Co.added to that last week when it unveiled its long-expected plans to offer a line of ProLiant servers powered by Advanced Micro Devices Inc. Coupled with announcements last month by Intel Corp. that it will add 64-bit extensions to its Xeon processors and Sun Microsystems Inc. s rollout of its Opteron-based systems, HPs decision greatly broadens users options as they plan their eventual move to 64-bit computing.
Sixty-four-bit computing is already commonplace using RISC-based processors. In the volume server world, the only real alternative has been Intels Itanium, an architecture separate from x86. Within the next few months, users in the x86 volume space will have a growing number of Xeon- and Opteron-based options from all the top OEMs that will run both 32-bit and 64-bit applications. Gordon Haff, an analyst with Illuminata Inc.said that for the next year or two, 64-bit computing will be used mainly in larger corporations and for high-performance computing applications.
But as mainstream applications start rubbing up against the memory limitations of 32-bit processors and as memory-hungry technologies such as virtualization grow, enterprises will begin turning toward 64-bit extended systems. The 64-bit horizon Feb. 10 Sun unveils line of Opteron-powered servers and systems with new UltraSPARC IV chips Feb. 24 HP announces Opteron-based ProLiant servers. For Townsend Analytics Ltd.a financial services software developer that has several hundred HP ProLiant servers in its data center, the 64-bit extensions offered by the Iq option zeit einstellen and the upcoming Xeons give the Chicago company the flexibility it needs.
Developers at Townsend twice looked at Itanium systems over the past three years but decided against them, questioning the amount of operating system support and whether they wanted to be tied to a single architecture. It actually gives us what we ideally wanted in the first place, which is to get to the point where we can take advantage of the high speed and high memory of 64-bit computing and get better performance out of our current 32-bit applications, said Jason Weil, Townsends head of software development.

MP3 to Wave Converter Plus Knowledge Base. Last updated February 29th, 2016. The right-click menu doesn t work with 64-bit versions of Windows. We do not have any updates that fix this problem. There are three solutions to the issue.
The easy solution. Download WOW64Menu from this link and install it. You ll now have a new option called Show Wow64 Menu when you right click an audio file. It looks like this. Once you click it, you ll see the Acoustica converter options as expected. Other possible work arounds. Right-cick on the Windows desktop, select New and then Shortcut.
In Type the location of this item, copy and paste the following without quotes Systemroot SysWOW64 explorer. Click Next and in Type a name for this shortcut call it Windows 32 bit Explorer. exe separate. Use that icon to browse to the location of your songs and you ll be able to convert them with the right-click menu. Windows 7 users note the 32-bit explorer shell work around outlined above does not work with 64-bit Windows 7.
The other way to use the converter with 64-bit Windows is to use the command line interface. Bring up a Windows command line interface by clicking on the Windows Start menu and typing command in the Run box or the Start Search box. mp3towave -C path_to_audio_file. Note that it needs the quotes around the path to the audio file and the c needs to be a capital C. Of course, the Audio Converter Pro executable directory must be in your path variable or you must put the explicit path to the executable in the command line call.
If you are converting to MP3, you ll need to specify the -3 flag. Flags -3 Convert to MP3 -C Convert to WAV -M Convert to WMA -G Convert to OGG. You can use the converter via the command line like this. For example to convert a. wma file into a. mp3 file, It might look like this. mp3towave -3 c my music mysong. If you are not in the converter folder, you could type. I-Mobile IQ X Lucus DTV with 64-bit SoC, 18MP rear camera and Digital TV.

I need to download windows 7 home Premium 64 Bit with sp1 to do reapair on laptop. Hello, I am repairing my friends laptop who is NOT technical and did not make restore discs. I need Windows 7 Home Premium 64 bit version. I have the Serial number on the bottom of the laptop. Its and Acer Aspire. You would THINK Acer would have a download available. I GET that the pc is out or warranty so they won t talk to me. I KNOW Microsoft took all their download links down.
They want you to get it from the manufacturer who won t talk to me. I DO get that. How can these people NOT provide this at Acer. I certainly can SUPPORT and fix their pc if only i had the tools available. I m not looking to pay their third party who can t help me. I have the product code on the bottom of the PC. They should at least have this available if you log in and go to downloads under OS there is a tab with Nothing.
You can still download the disk image from the microsoft website if you have the product key. Here is the link. You will need the product key on a sticker on the laptop to get the download. Thank you for that but that link only allows for you to enter a key from software that was purchased independently. It does not allow to download software OEM version and attempting to enter the product key on the laptop I am working on gives the following response.
The product key you ve entered appears to be for software which was pre-installed by the device manufacturer. Please contact the device manufacturer for software recovery options. Acer is doing customers a great diservice by not putting the OS on their download tap that says OS in support. Additionally I have encountered the laptop requires a password to get into the BIOS. I KNOW my friend has no clue as to why she should even attempt to go to the BIOS.
I cannot get the laptop to boot to the Windows disc. I was able to find an ISO. Its a SHAME everyone just cuts people off when they could fix their own PC s. Then they could not gouge people for insane ammounts of money for recovery disks for something freely downloadable on the web. It sounds like this was a company laptop, since it had the Pro version of windows and a locked down bios. The hard drive is also probably encrypted and will need to be replaced if you don t have the code.
I hope it is not a stolen machine. You will have to find the bios password, or else try a CMOS reset. I am certain it is not a stolen machine. My friend is a 20 year veteran of the company she works for. Microsoft wants you to go to the OEM Acer but Acer does not offer the download. I ll have to rest the CMOS. It may have been their laptop, but it was most certainly not stolen. i mean they don t even have an email address that i can send questions too.
ACER support site sucks and offers no solution that I can find. Does anybody know how to get around this. 99133 Points egydiocoelho 83487 Points MaClane 36522 Points brummyfan2 25288 Points JackE 21308 Points Kno63 16495 Points IVAN_PC 16387 Points billsey 13122 Points laurent_14 12667 Points xapim 11147 Points andylb. 100 Points egydiocoelho 45 Points Kno63 35 Points fibra 30 Points brummyfan2 30 Points JackE 29 Points hannahandrew 22 Points Mascotte1941 20 Points laurent_14 20 Points batmalin 17 Points SilvaGi.
These -m options are defined for the i386 and x86-64 family of computers -mtune cpu-type Tune to cpu-type everything applicable about the generated code, except for the ABI and the set of available instructions. The choices for cpu-type are generic Produce code optimized for the most common IA32 AMD64 EM64T processors. If you know the CPU on which your code will run, then you should use the corresponding -mtune option instead of -mtune generic.
But, if you do not know exactly what CPU users of your application will have, then you should use this option. As new processors are deployed in the marketplace, the behavior of this option will change. Therefore, if you upgrade to a newer version of GCC, the code generated option will change to reflect the processors that were most common when that version of GCC was released. There is no -march generic option because -march indicates the instruction set the compiler can use, and there is no generic instruction set applicable to all processors.
native This selects the CPU to tune for at compilation time by determining the processor type of the compiling machine. Using -mtune native will produce code optimized for the local machine under the constraints of the selected instruction set. Using -march native will enable all instruction subsets supported by the local machine hence the result might not run on different machines. In contrast, -mtune indicates the processor or, in this case, collection of processors for which the code is optimized.

While picking a specific cpu-type will schedule things appropriately for that particular chip, the compiler will not generate any code that does not run on the i386 without the -march cpu-type option being used. -march cpu-type Generate instructions for the machine type cpu-type.
The choices for cpu-type are the same as for -mtune. Moreover, specifying -march cpu-type implies -mtune cpu-type. -mcpu cpu-type A deprecated synonym for -mtune. -mfpmath unit Generate floating point arithmetics for selected unit unit. The choices for unit are 387 Use the standard 387 floating point coprocessor present majority of chips and emulated otherwise. Code compiled with this option will run almost everywhere.
The temporary results are computed in 80bit precision instead of precision specified by the type resulting in slightly different results compared to most of other chips. See -ffloat-store for more detailed description. This is the default choice for i386 compiler. sse Use scalar floating point instructions present in the SSE instruction set. This instruction set is supported by Pentium3 and newer chips, in the AMD line by Athlon-4, Athlon-xp and Athlon-mp chips.
The earlier version of SSE instruction set supports only single precision arithmetics, thus the double and extended precision arithmetics is still done using 387. Later version, present only in Pentium4 and the future AMD x86-64 chips supports double precision arithmetics too. For the i386 compiler, you need to use -march cpu-type-msse or -msse2 switches to enable SSE extensions and make this option effective.
For the x86-64 compiler, these extensions are enabled by default. The resulting code should be considerably faster in the majority of cases and avoid the numerical instability problems of 387 code, but may break some existing code that expects temporaries to be 80bit. This is the default choice for the x86-64 compiler. sse,387 sse 387 both Attempt to utilize both instruction sets at once. This effectively double the amount of available registers and on chips with separate execution units for 387 and SSE the execution resources too.
Use this option with care, as it is still experimental, because the GCC register allocator does not model separate functional units well resulting in instable performance. -masm dialect Output asm iq option zeit einstellen using selected dialect. Supported choices are intel or att the default one. Darwin does not support intel. -mieee-fp -mno-ieee-fp Control whether or not the compiler uses IEEE floating point comparisons.
These handle correctly the case where the result of a comparison is unordered. -msoft-float Generate output containing library calls for floating point. Warning the requisite libraries are not part of GCC. Normally the facilities of the machine s usual C compiler are used, but this can t be done directly in cross-compilation. You must make your own arrangements to provide suitable library functions for cross-compilation.
On machines where a function returns floating point results in the 80387 register stack, some floating point opcodes may be emitted even if -msoft-float is used. -mno-fp-ret-in-387 Do not use the FPU registers for return values of functions. The usual calling convention has functions return values of types float and double in an FPU register, even if there is no FPU. The idea is that the operating system should emulate an FPU.
The option -mno-fp-ret-in-387 causes such values to be returned in ordinary CPU registers instead. -mno-fancy-math-387 Some 387 emulators do not support the sincos and sqrt instructions for the 387. Specify this option to avoid generating those instructions. This option is the default on FreeBSD, OpenBSD and NetBSD. This option is overridden when -march indicates that the target CPU will always have an FPU and so the instruction will not need emulation. As of revision 2.
1, these instructions are not generated unless you also use the -funsafe-math-optimizations switch. -malign-double -mno-align-double Control whether GCC aligns doublelong doubleand long long variables on a two word boundary or a one word boundary. Aligning double variables on a two word boundary will produce code that runs somewhat faster on a Pentium at the expense of more memory. On x86-64, -malign-double is enabled by default. Warning if you use the -malign-double switch, structures containing the above types will be aligned differently than the published application binary interface specifications for the 386 and will iq option zeit einstellen be binary compatible with structures in code compiled without that switch.
-m96bit-long-double -m128bit-long-double These switches control the size of long double type. The i386 application binary interface specifies the size to be 96 bits, so -m96bit-long-double is the default in 32 bit mode. Modern architectures Pentium and newer would prefer long double to be aligned to an 8 or 16 byte boundary. In arrays or structures conforming to the ABI, this would not be possible.
So specifying a -m128bit-long-double will align long double to a 16 byte boundary by padding the long double with an additional 32 bit zero. In the x86-64 compiler, -m128bit-long-double is the default choice as its ABI specifies that long double is to be aligned on 16 byte boundary. Notice that neither of these options enable any extra precision over the x87 standard of 80 bits for a long double.
Warning if you override the default value for your target ABI, the structures and arrays containing long double variables will change their size as well as function calling convention for function taking long double will be modified. Hence they will not be binary compatible with arrays or structures in code compiled without that switch. -mlarge-data-threshold number When -mcmodel medium is specified, the data greater than threshold are placed in large data section.
This value must be the same across all object linked into the binary and defaults to 65535. -mrtd Use a different function-calling convention, in which functions that take a fixed number of arguments return with the ret num instruction, which pops their arguments while returning. This saves one instruction in the caller since there is no need to pop the arguments there.
You can specify that an individual function is called with this calling sequence with the function attribute stdcall. You can also override the -mrtd option by using the function attribute cdecl. See Function Attributes. Warning this calling convention is incompatible with the one normally used on Unix, so you cannot use it if you need to call libraries compiled with the Unix compiler. Also, you must provide function prototypes for all functions that take variable numbers of arguments including printf ; otherwise incorrect code will be generated for calls to those functions.
Normally, extra arguments are harmlessly ignored. -mregparm num Control how many registers are used to pass integer arguments. By default, no registers are used to pass arguments, and at most 3 registers can be used. You can control this behavior for a specific function by using the function attribute regparm. In addition, seriously incorrect code will result if you call a function with too many arguments. Warning if you use this switch, and num is nonzero, then you must build all modules with the same value, including any libraries.
-msseregparm Use SSE register passing conventions for float and double arguments and return values. You can control this behavior for a specific function by using the function attribute sseregparm. This includes the system libraries and startup modules. Warning if you use this switch then you must build all modules with the same value, including any libraries. -mpc32 -mpc64 -mpc80 Set 80387 floating-point precision to 32, 64 or 80 iq option zeit einstellen.
When -mpc32 is specified, the significands of results of floating-point operations are rounded to 24 bits single precision ; -mpc64 rounds the significands of results of floating-point operations to 53 bits double precision and -mpc80 rounds the significands of results of floating-point operations to 64 bits extended double precisionwhich is the default. When this option is used, floating-point operations in higher precisions are not available to the programmer without setting the FPU control word explicitly.
Setting the rounding of floating-point operations to less than the default 80 bits can speed some programs by 2 or more. -mstackrealign Realign the stack at entry. Note that some mathematical libraries assume that extended precision 80 bit floating-point operations are enabled by default; routines in such libraries could suffer significant loss of accuracy, typically through so-called catastrophic cancellationwhen this option is used to set the precision to less than extended precision.
On the Intel x86, the -mstackrealign option will generate an alternate prologue and epilogue that realigns the runtime stack if necessary. This supports mixing legacy codes that keep a 4-byte aligned stack with modern codes that keep a 16-byte stack for SSE compatibility. See also the attribute force_align_arg_pointerapplicable to individual functions.
-mpreferred-stack-boundary num Attempt to keep the stack boundary aligned to a 2 raised to num byte boundary. If -mpreferred-stack-boundary is not specified, the default is 4 16 bytes or 128 bits. -mincoming-stack-boundary num Assume the incoming stack is aligned to a 2 raised to num byte boundary. On Pentium and PentiumPro, double and long double values should be aligned to an 8 byte boundary see -malign-double or suffer significant run time performance penalties.
On Pentium III, the Streaming SIMD Extension SSE data type __m128 may not work properly if it is not 16 byte aligned. To ensure proper alignment of this values on the stack, the stack boundary must be as aligned as that required by any value stored on the stack. Further, every function must be generated such that it keeps the stack aligned. Thus calling a function compiled with a higher preferred stack boundary from a function compiled with a lower preferred stack boundary will most likely misalign the stack.
If -mincoming-stack-boundary is not specified, the one specified by -mpreferred-stack-boundary will be used. It is recommended that libraries that use callbacks always use the default setting. This extra alignment does consume extra stack space, and generally increases code size. Code that is sensitive to stack space usage, such as embedded systems and operating system kernels, may want to reduce the preferred alignment to -mpreferred-stack-boundary 2.
2 -msse4 -mno-sse4 -mavx -mno-avx -maes -mno-aes -mpclmul -mno-pclmul -msse4a -mno-sse4a -mfma4 -mno-fma4 -mxop -mno-xop -mlwp -mno-lwp -m3dnow -mno-3dnow -mpopcnt -mno-popcnt -mabm -mno-abm These switches enable or disable the use of instructions in the MMX, SSE, SSE2, SSE3, SSSE3, SSE4. 1, AVX, AES, PCLMUL, SSE4A, FMA4, XOP, LWP, ABM or 3DNow. extended instruction sets.
These extensions are also available as built-in functions see X86 Built-in Functions, for details of the functions enabled and disabled by these switches. To have SSE SSE2 instructions generated automatically from floating-point code as opposed to 387 instructionssee -mfpmath sse. GCC depresses SSEx instructions when -mavx is used. Instead, it generates new AVX instructions or AVX equivalence for all SSEx instructions when needed.
These options will enable GCC to use these extended instructions in generated code, even without -mfpmath sse. -mmmx -mno-mmx -msse -mno-sse -msse2 -mno-sse2 -msse3 -mno-sse3 -mssse3 -mno-ssse3 -msse4. Applications which perform runtime CPU detection must compile separate files for each supported architecture, using the appropriate flags. In particular, the file containing the CPU detection code should be compiled without these options.
-mfused-madd -mno-fused-madd Do don t generate code that uses the fused multiply add or multiply subtract instructions. The default is to use these instructions. -mcld This option instructs GCC to emit a cld instruction in the prologue of functions that use string instructions. String instructions depend on the DF flag to select between autoincrement or autodecrement mode.
While the ABI specifies the DF flag to be cleared on function entry, some operating systems violate this specification by not clearing the DF flag in their exception dispatchers. The exception handler can be invoked with the DF flag set which leads to wrong direction mode, when string instructions are used. This option can be enabled by default on 32-bit x86 targets by configuring GCC with the --enable-cld configure option.
-mcx16 This option will enable GCC to use CMPXCHG16B instruction in generated code. CMPXCHG16B allows for atomic operations on 128-bit double quadword or oword data types. This is useful for high resolution counters that could be updated by multiple processors or cores. This instruction is generated as part of atomic built-in functions see Atomic Builtins for details.
Generation of cld instructions can be suppressed with the -mno-cld compiler option in this case. -msahf This option will enable GCC to use SAHF instruction in generated 64-bit code. Early Intel CPUs with Intel 64 lacked LAHF and SAHF instructions supported by AMD64 until introduction of Pentium 4 G1 step in December 2005. LAHF and SAHF are load and store instructions, respectively, for certain status flags.
In 64-bit mode, SAHF instruction is used to optimize fmoddrem or remainder built-in functions see Other Builtins for details. -mmovbe This option will enable GCC to use movbe instruction to implement __builtin_bswap32 and __builtin_bswap64. -mcrc32 This option will enable built-in functions, __builtin_ia32_crc32qi__builtin_ia32_crc32hi.
__builtin_ia32_crc32si and __builtin_ia32_crc32di to generate the crc32 machine instruction. -mrecip This option will enable GCC to use RCPSS and RSQRTSS instructions and their vectorized variants RCPPS and RSQRTPS with an additional Newton-Raphson step to increase precision instead of DIVSS and SQRTSS and their vectorized variants for single precision floating point arguments. These instructions are generated only when -funsafe-math-optimizations is enabled together with -finite-math-only and -fno-trapping-math.
Note that while the throughput of the sequence is higher than the throughput of the non-reciprocal instruction, the precision of the sequence can be decreased by up to 2 ulp i. the inverse of 1. 0f sqrtf x in terms of RSQRTSS or RSQRTPS already with -ffast-math or the above option combinationand doesn t need -mrecip. Note that GCC implements 1.
-mveclibabi type Specifies the ABI type to use for vectorizing intrinsics using an external library. Supported types are svml for the Intel short vector math library and acml for the AMD math core library style of interfacing. GCC will currently emit calls to vmldExp2vmldLn2vmldLog102vmldLog102vmldPow2vmldTanh2vmldTan2vmldAtan2vmldAtanh2vmldCbrt2vmldSinh2vmldSin2vmldAsinh2vmldAsin2vmldCosh2vmldCos2vmldAcosh2vmldAcos2vmlsExp4vmlsLn4vmlsLog104vmlsLog104vmlsPow4vmlsTanh4vmlsTan4vmlsAtan4vmlsAtanh4vmlsCbrt4vmlsSinh4vmlsSin4vmlsAsinh4vmlsAsin4vmlsCosh4vmlsCos4vmlsAcosh4 and vmlsAcos4 for corresponding function type when -mveclibabi svml is used and __vrd2_sin__vrd2_cos__vrd2_exp__vrd2_log__vrd2_log2__vrd2_log10__vrs4_sinf__vrs4_cosf__vrs4_expf__vrs4_logf__vrs4_log2f__vrs4_log10f and __vrs4_powf for corresponding function type when -mveclibabi acml is used.
A SVML or ACML ABI compatible library will have to be specified at link time. -mabi name Generate code for the specified calling convention. Permissible values are sysv for the ABI used on GNU Linux and other systems and ms for the Microsoft ABI. The default is to use the Microsoft ABI when targeting Windows. On all other systems, the default is the SYSV ABI.
You can control this behavior for a specific function by using the function attribute ms_abi sysv_abi. -mpush-args -mno-push-args Use PUSH operations to store outgoing parameters. This method is shorter and usually equally fast as method using SUB MOV operations and is enabled by default. In some cases disabling it may improve performance because of improved scheduling and reduced dependencies. -maccumulate-outgoing-args If enabled, the maximum amount of space required for outgoing arguments will be computed in the function prologue.
This is faster on most modern CPUs because of reduced dependencies, improved scheduling and reduced stack usage when preferred stack boundary is not equal to 2. The drawback is a notable increase in code size. This switch implies -mno-push-args. -mthreads Support thread-safe exception handling on Mingw32. Code that relies on thread-safe exception handling must compile and link all code with the -mthreads option. When compiling, -mthreads defines -D_MT ; when linking, it links in a special thread helper library -lmingwthrd which cleans up per thread exception handling data.
-mno-align-stringops Do not align destination of inlined string operations. This switch reduces code size and improves performance in case the destination is already aligned, but GCC doesn t know about it. -minline-all-stringops By default GCC inlines string operations only when destination is known to be aligned at least to 4 byte boundary. This enables more inlining, increase code size, but may improve performance of code that depends on fast memcpy, strlen and memset for short lengths.
-minline-stringops-dynamically For string operation of unknown size, inline runtime checks so for small blocks inline code is used, while for large blocks library call is used. -mstringop-strategy alg Overwrite internal decision heuristic about particular algorithm to inline string operation with. The allowed values are rep_byterep_4byterep_8byte for expanding using i386 rep prefix of specified size, byte_looploopunrolled_loop for expanding inline loop, libcall for always expanding library call.
-momit-leaf-frame-pointer Don t keep the frame pointer in a register for leaf functions. This avoids the instructions to save, set up and restore frame pointers and makes an extra register available in leaf functions. The option -fomit-frame-pointer removes the frame pointer for all functions which might make debugging harder. -mtls-direct-seg-refs -mno-tls-direct-seg-refs Controls whether TLS variables may be accessed with offsets from the TLS segment register gs for 32-bit, fs for 64-bitor whether the thread base pointer must be added.
Whether or not this is legal depends on the operating system, and whether it maps the segment to cover the entire TLS area. For systems that use GNU libc, the default is on. -msse2avx -mno-sse2avx Specify that the assembler should encode SSE instructions with VEX prefix. The option -mavx turns this on by default. These -m switches are supported in addition to the above on AMD x86-64 processors in 64-bit environments.
-m32 -m64 Generate code for a 32-bit or 64-bit environment. For darwin only the -m64 option turns off the -fno-pic and -mdynamic-no-pic options. -mno-red-zone Do not use a so called red zone for x86-64 code. The red zone is mandated by the x86-64 ABI, it is a 128-byte area beyond the location of the stack pointer that will not be modified by signal or interrupt handlers and therefore can be used for temporary data without adjusting the stack pointer.
The flag -mno-red-zone disables this red zone. -mcmodel small Generate code for the small code model the program and its symbols must be linked in the lower 2 GB of the address space. Pointers are 64 bits. -mcmodel kernel Generate code for the kernel code model. The kernel runs in the negative 2 GB of the address space. This model has to be used for Linux kernel code. -mcmodel medium Generate code for the medium model The program is linked in the lower 2 GB of the address space. Symbols with sizes larger than -mlarge-data-threshold are put into large data or bss sections and can be located above 2GB.
Small symbols are also placed there. -mcmodel large Generate code for the large model This model makes no assumptions about addresses and sizes of sections. Both -ftree-vectorize and -funsafe-math-optimizations have to be enabled. Importing data from 64-bit Excel in SSIS. Conquering Data. Last night I was sqlhelping someone on twitter having an issue with importing data from excel. Hrvoje Piasevoli BI Blog. The data preview dialog returned results correctly, while the package errored at run time with a connection error.
Tip install both 32bit and 64bit version of providers for your data sources if they are available. The issue was caused by Run64BitRuntime property of the package being set to true and it is in fact a well known and common issue with 64bit SSIS. Then it occurred to me to try it myself on my setup as I m running 64-bit W7, 64-bit SQL stack and most importantly the first release of 64-bit Excel 2010.
So, I created a new package in a SSIS project and created a dataflow task. The obvious path. Then dragged an Excel Source from Data Flow Sources and clicked on new connection manager to define the connection to an excel file I was trying to import. The Microsoft. If you try to select the sheet from the dropdown in Table or view Data access mode the following error dialog jumps in to your face.
End then problems begin. It boils down to provider not being registered on the machine. Simlar but more verbose error is thrown if you try the SQL command as Data access mode with something like. As I have already pointed out the installed version of Excel 2010 on my machine is 64bit and BIDS being a 32-bit application can not load 64-bit stuff. 0 provider installed is 64-bit. The next obvious path.
After downloading and running the setup for AccessDatabaseEngine. exe you get the following error. So it turns out you can t have both 32-bit and 64-bit of the provider installed on the same machine. Note that this is all due to the fact that BIDS Visual Studio is a 32-bit application. So, is it hopeless. In fact you have two solutions to overcome this issue.
Solution 1 using the SQL Server Import and Export Wizard. But let s go through the steps which are quite straightforward if you have used the wizard before with just a minor tweak. The most important thing is to start the 64-bit version Import and Export Data 64-bit. Ok, start the Import and Export Data 64-bit wizard and select Microsoft Office 12.
0 Access Database Engine OLE DB Provider as shown on the following picture. Now click on Properties and set the path to your excel file in the Data Source text box. Clicking on the Test Connection button yields the following error dialog. This is the minor tweak needed that I mentioned earlier. Well, this will work but it is kind of a 1 time solution because it will create an unmanageable package. Switch to All tab in the Data Link Properties dialog and double click on Extended Properties.
Insert Excel 12. 0 in the Property Value without quotes and click OK. Return to the Connection tab and click Test Connection button. It should suceed now. Here I have set it to database TEST on my local named instance of SQL server localhost SQL2008. After clicking next, choose from the options. Lets just leave it at the default for now and click next. Place a check for the sheet that contains data and either leave the default destination on choose from existing tables.
We ll skip the mappings part for now and just click Preview to test. In the Save and Run Package step of the wizard leave checked Run immediately and check Save SSIS Package with the File system destination option and click next. dtsx in My Documents and click next. A summary of settings is displayed. I had trouble naming the package so just leave it with default values New Package. Remember we selected the option to run the package immediately, so the package is started and we get the following screen.
You can test it from SSMS. Next set the destination. Now let s open the package in Visual Studio 2008 or BIDS. Click on the Error List pane and note the errors. And that leads us to an alternate solution. Solution 2 Using OLE DB Source in DataFlow with SQL Server as the Data Source. This solution will result in a maintainable and editable package that has no dependency on the development platform. It will work even if you do not have the Microsoft.
0 provider installed as long as the provider is installed on any remote machine running SQL server 64-bit provided you have access to it. You will not be able to work with this dataflow in designer. As this solution uses OPENROWSET to provide data from Excel we have to setup SQL server options. Fire up SSMS and execute the following script on the instance of sql server 64-bit that you will be using.
I was using my local instance of SQL Server 2008 Developer Edition 64-bit. If you are using anything other than test dev server consult your system admin first. Now test the configuration with a query similar to this adjust the excel path for your environment. If the tests pass and results are returned we can move on. Fire up BIDS or Visual Studio and create a new SSIS Project. Drag a data flow task in the control flow and double click on it to open the Data Flow tab.
Now drag an OLE DB Source component from the Data Flow Sources and double click to configure it. Create the connection manager to the SQL server that you will be using. Set the database to the database that you will be importing the excel data this is not required but I have used the same connection for the OLE DB destination to keep it simple and stupid.
From the Data access mode dropdown select SQL command SQL command from variable is also an option but it is not important for the concept. Type in paste your test query in the SQL command text box. Now click on the Preview button to test your query. It should display results if everything is setup ok. Now drag an OLE DB destination to the data flow, connect the source component to the destination and configure your destination connection and table.
I m reusing the same connection manager. Configure column mappings and you are ready to go. Right click somewhere in the data flow and select Execute Task to run the data flow task. Well, this turned longer to write than I expected but I know I have saved a lot of time to a lot of peeps in the Community. I ve tried the procedure using the 64-bit Import Export Wizard with no success. On a fresh SQL 2008 R2 install Windows 2008 R2 x64 I ve installed the Office 2010 64 bit ACE.
I follow the procedure and I get as far as testing the connection, which succeeds. Once I press Next, the program terminates and Windows Server tells me that it has. Just open the xlsx in office 2010 and save as xls, then import from BIDS as always. I didn t quite get to complete that post. But the jist is there. Is there an earlier version of ACE that I should be using. Hi Andrew, I ve just tested the Import Export Wizard on SQL 2008 R2 64 bit W2k8 R2 with ACE 64 bit and works without problems.
Note that I also have Excel 2010 installed on that server. Can I contact you over e-mail skype gtalk. My account is hrvoje. Hi Andrew, I just want to update with my latest testing. After having uninstalled Excel from the server, removing Desktop experience feature and installing the Office ACE 64bit provider I can confirm that Import Export Wizard on SQL 2008 R2 64 bit W2k8 R2 with ACE 64 bit works without problems. The first solution does not allow you to edit the package, which many of us need to add things like unpivots and other transforms.
I have problem with Solution 2 Using OLE DB Source in DataFlow with SQL Server as the Data Source i got OLE DB provider Microsoft. 0 for linked server null returned message Unspecified error. Msg 7303, Level 16, State 1, Line 1 Cannot initialize the data source object of OLE DB provider Microsoft. 0 for linked server null.
Hi, Have you set the server properties first code snippet. Do you have the Office ACE 64bit provider installed on your SQL server. Hi, I set the server properties from the first code snippet and my admin installed Microsoft Access Database Engine 2010 Redistributable 64bit and I have still the error Ahmad_hashemi described. Any idea, what could be the problem. I m having a problem using the solution 2 but in a Store Procedure.
Sometimes, if I try to load many excel files, the transaction never ends, and when you cancel, it stays rolling back for all eternity, or until you reset the SQL server. Did it ever happened to you using SSIS. Maybe it s time to change to SSIS. Hi, no I haven t done any excessive testing at all unfortunately. What a wonderfully written post nice job and yes, you saved me a LOT of time and hassle.
Hi Richard, so nice to here that. Thanks for dropping a comment other than it s not working for me. What I didn t realize when I was writing the post was that it d also save my time more than once. FYI, I was able to get this working using the ACE OLEDB driver directly as an OLE DB Source in a dataflow without needing to go through SQL Server or OPENROWSET. I m sorry to say that you have missed to understand the problem described.
What I am describing in my post is how to solve the problem of importing data from Excel or be it any other data source that has ONLY 64-bit drivers installed and the 32-bit drivers are not available or as in the case of ACE OLEDB drivers can t be installed side-by-side see the 4th screenshot from top. So, the OS bitness is not relevant here it is the unavailability of 32-bit data source provider, for all the reasons explained at the beginning of the post.
So I suggest you update your post to make this a bit clearer. OS bitness is indirectly relevant in that it affects the availability of WOW64 for BIDS and which flavor of dtexec runs by default. Even though it s a 32-bit app BIDS should be able to use the already installed in your scenario 64-bit ACE OLEDB driver, but only if you use an OLE DB source and connection manager instead of an Excel source. If everything is ok you should see the beautiful green boxes all around. Correction to this you can use the already installed 64-bit driver from dtexec, but possibly not BIDS itself.
No not at all. People like Hrvoje make insurmountable tasks simple with easy to follow instructions. Worked like a champ. Thank you for taking the time to teach us. Nice post buddy. Easy solution is to run Office 2007 32 bit after the 64 bit install, as it doesn t do the checks. Hi Mark, I didn t know that. However, I am not sure I would be comfortable doing or recommending that as it doesn t sound like a supported scenario.
I spent the past 45 minutes Googling different ways of getting an XLSX file into SQL via SSIS on a 64bit system with the 64bit Access 2010 drivers installed, and pieced together the solution one bit of code at a time. After I felt very good about myself for solving the problem I came across this blog post which made me make the sounds Homer Simpson makes when he s done something stupid or when he just realized something DOPE. In South Africa we have a similar sound to Homer s Dopeand it s called Eish.
So a HUGE Eish to myself for not finding this wonderfully written article 45 minutes ago I guess the upside is I have learnt something new, which is always a good thing. Hrvoje, you re a god. But your method number 2 did yield amazing results. And I m thankful for that. As many here, I was nearly crumbling under the pressure of getting some Excel tables gone to SQL, and the bloody driver just won t play with my x64 MSSQLServer instance.
However, I cut short the method by using a shortcut. Since I only needed some specific tables frommy xlsx in the database, once I managed to query the file I just did INSERT INTO table SELECT FROM OPENROWSET and it worked like a charm. Thanks for this very handful solution. One thing I discovered that may help someone else is the error DTS_E_OLEDB_EXCEL_NOT_SUPPORTED The Excel Connection Manager is not supported in the 64-bit version of SSIS, as no OLE DB provider is available is somewhat misleading, especially the last part saying no provider is available when you know it is there and can verify it in a number of ways that it is installed correctly.
So instead of using that as a source adapter, use a regular OLEDB Connection Manager and Source, and specify the Extended Properties Excel 12. 0;HDR YES; for Excel 2007 2010 files. I think the real issue is the Excel Source is not 64-bit compatible. xlsx and Excel 8. 0;HDR YES; for lower versions.
