32bit and 64bit oracle 9.2

Dear Guru's,
                   I have SAP 4.7 ext 200 with oracle 9.2 and windows 2003 standard edition all these are 32bit .Now my client wants to buy new hardware which is 64bit to implement the same version mentioned above.for SAP4.7 64bit kernel is available in SMP but I didnt find oracle 9.2 64bit .Please advice whether SAP 4.7 ext 200 can be installed with 64bit kernel and oracle 9.2 64bit available(OS win2003 64bit) on 64bit hardware  or all the OS and SAP with oracle 32bit on 64bit hardware should we choose.
Best Regards,
Sanju

Well... those are the rumours - which are just that.
Itanium is a 64bit processor - yes - but it´s a totally different architecture. Those programs will NOT run on an Intel Xeon processor. The difference between those two is, that one is IA64 (Itanium-2) and the other is X86_64 (also called x64).
You will need an installation CD set for that x86_64 (or x64) - NOT for Itanium if you have an Intel Xeon processor.
Read the following notes:
960769 - Windows: Migration from 32-bit to 64-bit (x86_64)
931024 - FAQ: 64-bit platforms for Windows
Especially the second will explain the differences.
It makes no sense to install 32bit (SAP-) application software on a 64bit operating system since there are native 64bit binaries to use, without them, you won´t benefit of the 64bit hardware. You need to check, however, that 3rd party software (backup etc.) has also 64bit clients for your combination.

  • Windows 7 64-bit and need to install both 32bit and 64bit Oracle 11g client

    Hello
    First I am sorry for asking what is probably a common knowledge answer from most in the forum. I just cannot find a straight forward answer searching these forums or via google.
    We have Windows 7 64-bit planned as our next desktop upgrade. We have several Oracle databases, and all of the client software in our environment is 32 bit.
    I want to try and be ahead of the curve so I want to deploy the latest 64-bit 11g client instead of our current client (10g 32bit).
    The simple question is this: Can we actually do that with our 32bit application suite or do I need to install the 32bit client for 32bit applications side-by-side with the 64bit 11g Oracle client for future 64-bit clients?
    For a follow up to that, if I do, then does anyone have good instructions on that? I found one article on this but it seemed custom and made use of the mklink command, so I have my doubts this is correct.
    Thanks

    Thanks for the tip. What I wonder though is should I do that or does the 64-bit client have a 32-bit layer that works with 32-bit applications or, am I forced to still deploy a 32-bit client because of my 32-bit software?
    Thanks

  • Can 32bit and 64bit clients coexist?

    Hello folks,
    I have a Windows Server 2003 64bit machine running Websphere 6.0 Express (32bit). Additionally it's running a custom 64bit application. Both apps need to connect to separate 10g databases. Can the 32bit and 64bit Oracle client installs coexist on this machine?
    Thanks for any advice!
    -Sangamon

    To clarify, Websphere needs a 32bit JDBC driver, our custom application needs a 64bit ODBC driver. I've got Websphere working, but I'm having trouble getting the ODBC driver to work. I'm wondering if there's a problem with having 2 clients installed.

  • TNS Timeout Error with both 32bit and 64bit drivers installed

    I have a server running WIndows 2008 64bit and SQL Server 2012 64bit. I have both the 32bit and 64bit Oracle ODBC drivers installed. 32bit is for SSIS and SSRS uses 64bit. I have an ODBC connection setup for both the 32bit and 64bit. I have the datasources setup for the 64bit and when I test it it works. When I go to run a query I get TNS timeout errors. Any ideas?

    Thank you very much, Curt!
    It's right: When the 64bit version is running, then the PSDs will be opened by this.
    But the configuration under "Bridge Edit/preferences/file type assoiciatons" has the same result as under the "Windows/Systemcontrol/Standardprograms": Never they show the name "Adobe Photoshop.exe (64bit)" - only "Adobe Photoshop.exe" In both cases (Bridge and systemcontrol) I have the possibility to choose the "right" Photoshop.exe by going to the right file (32bit OR 64bit), but the name of the .exe is ever the same: Only "Adobe Photoshop.exe". There is no difference.
    And so even if the 64bit version is preferred (in Bridge), the PSD-files will be opened in the 32bit-version, when no one of both versions is running.
    But - so or so - you have given me a way to solve my basic-problem!
    And when I find the time for experiments, I will show what happens, when I rename the 64bit-exe to "Adobe Photoshop64.exe" to get two different filenames for Photoshop in the Windows-System. (I'm not shure if this will function: When in the Photoshop-System are intrinsic lnks/references to "Photoshop.exe", then I will have no success! Therefore I have to make a HDD-Clone with the whole Windows-System, all Apps and my Working-data before I try to rename. Perhaps there is "no way back to the activation" after renaming the .exe ...
    Thank you and kind regards,
    Oh-Mann

  • What's different between 32bit and 64bit ?

    Hi all,
    What's different between 32bit and 64bit for Oracle Database 10g Release 1 ?
    such as "Oracle Database 10g Release 1 (10.1.0.2) for Microsoft Windows (32-bit)"
    and "Oracle Database 10g Release 1 (10.1.0.2) for Microsoft Windows (64-bit Itanium)"
    Thanks
    fish

    What's different between 32bit and 64bit ? oooh, about 32 bits ;)
    what is different between (x64) and (64-bit Itanium)This really is the short of question google could answer better but in a nutshell Itanium is the Intel 64bit chip (AKA the Itanic, due to its troubled history). Whereas x64 is the appelation given to AMD's 64bit Opteron chips; I believe x64 was coined by Microsoft but Sun use it as well.
    Cheers, APC.

  • Does iTunes come with 32bit and 64bit install?

    I have Windows 7 and it's a 32bit and 64bit Gaming Laptop G73SW.
    I've done all the troubleshoot tips, which has just made my computer worse.eg all icons changed, things now missing, so probably have to do a System Retore to get it all back.
    Every time i speak to Apple,  they're suggestions just make my computer stuffed, iTunes takes over all my programs etc.
    Simply put: Does iTunes come with a 32bit and 64bit Install??? If not i won't be using that program.
    Which makes it hard for my line of work atm as an Alpha and Beta Games Tester for many Private Platforms i play on.

    Well genius, it's either a 32bit or 64bit system, it cannot be both.

  • Installing PS CS5.1 32bit and 64bit

    I accepted the defaults while installing photoshop and it seems 2 versions installed?  Do I need both the 32bit and 64bit versions on Windows 7 64bit ?  Also, when I look at installed programs it only indicates Photoshop CS5 without any 32bit or 64bit designation.  What is necessary here.  Are there bugs with the 64bit version like MS Office so the 32 bit version installs also? 
    thanks
    Milton

    Both 32 and 64 bit variants are provided in case you have plug-ins or drivers that only work with one.  For example, older plug-ins are generally 32 bit only, and there are no 64 bit TWAIN drivers.
    64 bit Photoshop will allow you access to your entire memory space, in excess of 2 GB, while 32 bit Photoshop will be limited.
    Advice:  Keep 'em both, use 64 bit primarily, and use the 32 bit version if/when you have to.

  • Install Photoshop 32bit AND 64bit

    hi,
    is it possible to install Photoshop 32bit and 64bit on one system?
    im currently running 64 bit, but it doesnt recognize my 32bit filters...
    if not, is there much difference in performance between the 64 and 32bit version? [btw: i am running Windows Vista 64bit Home Premium SP2]

    oh....
    lol
    sorry XD
    i see now, i have both
    and is there much difference in performance between 64 and 32 bit?

  • Regarding 32bit and 64bit libraries

    Hi,
    Can any one please clarify my quries below.
    1) What is the difference between 32bit and 64bit library.
    2) How to identify the 32bit and 64bit library? Is there any naming convention fallowed?
    3) From which version onwards of Sun Studio, 64 bit libraries are supported?
    Regards,
    Vignesh

    The platforms suppported by Sun compilers have both 32-bit and 64-bit modes of operation. The two modes cannot be mixed in a single program. A 64-bit platform can run 32-bit code, but not the other way around.
    On the supported platforms, 32-bit mode is known a ILP32, meaning that types int, long, and pointer are all 32 bits. 64-bit mode is known as LP64, meaning that type int is still 32 bits, but types long and pointer are 64 bits. (Other systems, not supported by Sun compilers, can have different definitions.)
    The 64-bit mode of the processors supports different instruction sets. The amd64 processor also has different register sets. The layout of objects is different in the two modes, and the way functions are called is different. (There are other differences as well.)
    A program compiled in 32-bit mode must link to 32-bit libraries, not 64-bit libraries, for reasons which I hope are now obvious. A program compiled in 64-bit mode must link to 64-bit libraries.
    The Sun compilers automatically link to the right library version of system libraries, as long as you use consistent options when compiling and linking. For example, you could build a 64-bit sparc program this way:   CC -xarch=v9 -c f1.cc
      CC -xarch=v9 -c f2.cc
      CC -xarch=v9 f1.o f2.o -o myprog The 64-bit version of the various system runtime libraries will be linked automatically, given the -xarch=v9 option on each command line.
    If you create both 32-bit and 64-bit versions of a library of your own, you must arrange to name them differently or put them in different subdirectories. If you give them the same name and put them in differrent subdirectories (which is the convention for system libraries on Solaris), you can use different -L options at link time to point to the right directory.
    You can use the Solaris "file" command to find out whether a program or library is 32-bit or 64-bit.`
    Example, this time on a Solaris Opteron system:
    % file /usr/lib/libCrun.so.1
    /usr/lib/libCrun.so.1: ELF 32-bit LSB dynamic lib 80386 Version 1, dynamically linked, not stripped, no debugging information available
    78% file /usr/lib/amd64/libCrun.so.1
    /usr/lib/amd64/libCrun.so.1: ELF 64-bit LSB dynamic lib AMD64 Version 1 [CMOV], dynamically linked, not stripped, no debugging information available

  • Configuring 32bit and 64bit extproc

  • Stupid question: Difference between 32bit and 64bit 10g Client?

    We have an application (Informatica 8, 32bit) for which the vendors claim they only support a 32bit client. Oracle does not ship a word-size specific client for 10g. This leads me to believe that 32bit vs 64bit is really innocuous and perhaps irrelevant. For my own curiosity, is the 10g client (not Instant Client) actually 32bit or 64bit?

    Hi,
    Note that you can always run 32-bit apps on a 64-bit client . . . . .
    There are separate clients for 32-bit and 64-bit instant clients:
    http://www.oracle.com/technology/software/tech/oci/instantclient/index.html
    Instant Client for Microsoft Windows (32-bit)
    Instant Client for Microsoft Windows 64-bit Itanium
    Instant Client for Microsoft Windows (x64)
    Instant Client for Linux x86
    Instant Client for Linux x86-64
    Instant Client for Linux Itanium
    Instant Client for Linux AMD64 (32-bit and 64-bit)
    Instant Client for Linux on Power (32-bit)
    Instant Client for Linux on Power (64-bit)
    Instant Client for z/Linux (32-bit and 64-bit)
    Instant Client for Mac OS X (Intel x86)
    Instant Client for Mac OS X (PPC)
    Instant Client for Solaris Operating System (SPARC) (64-bit)
    Instant Client for Solaris Operating System (SPARC) (32-bit)
    Instant Client for Solaris x86
    Instant Client for Solaris x86-64
    Instant Client for HP-UX PA-RISC (64-bit)
    Instant Client for HP-UX PA-RISC (32-bit)
    Instant Client for AIX5L (64-bit)
    Instant Client for AIX5L (32-bit)
    Instant Client for HP Tru64 UNIX
    Instant Client for HP-UX Itanium (64-bit)

  • Export & import between 32bit and 64bit windows

    I need to move a schema over from a 32-bit windows machine to a 64-bit windows machine.
    both machines are network mapped,
    so
    I exp it out from 32 machine
    copy and paste from 32 to 64 machines
    then imp into 64 machine
    and get this error
    IMP-00010: not a valid export file, header failed verification
    IMP-00000: Import terminated unsuccessfully
    machine oracle utilities are:
    Export: Release 10.2.0.1.0
    Import: Release 10.2.0.1.0
    help please.

    Are you using original exp/imp or data pump?
    exp/imp should be able to handle 32bit to 64bit transport.
    It's either your dump file got corrupted during transfer.
    Or your database server is not same version as your utilities. Please verify and post your Oracle server version.

  • Labview 32bit and 64bit on the same computer?

    Hi guys,
    I need to setup a PicoScope Scope with 32bit dlls with my existing Labview-64bit-code. Can I run Labview 32bit and Labview 64bit on the same machine and let them communicate via shared variables?
    Thanks Jan

    I'm currently using a ni scope on a 32bit machine and acquiring data over the network. It slows things down. I want to run the data acquisition on 1 computer to avoid the delay.
    I could put the acquisition code in labview 32bit, but would rather avoid that, too.

  • Satellite A350D PSAKCE - Bios 32bit and 64bit update

    Hello guys.
    I need to upgrade my A350D PSAKCE bios. But I don't know what is the difference between Windows_BIOS_Package_V330_1 and Windows_BIOS_Package64_V330_1. Which should I install? I am using Windows 7 Ultimate 64bit edition.

    Hi
    Usually you should not get any serious issues if you would downgrade the OS to 32bit and will still use the BIOS 64bit. But in some very rare cases some features like FN buttons or similar would not function very well
    It could be also possible that only 3.2GB RAM would be recognized due to 32bit OS limitation
    So in your case I would stay with 64bit OS.
