SAP XI 7.0 on Solaris 10 X86

Hi,
have you got experience with SAP XI/PI 7.0 on Solaris 10 with Oracle X86/X64 ?
Regards.

We use Solaris 10 x64 (x86_64) to consolidate servers (EP, SRM, AS-Java, SolMan...) using zones and ZFS and we are very happy with it.

  • SAP on solaris x86 or sparc

    Hi,
    Can you please let me know the advantages of running SAP on Solaris X86 or SPARC machines. Which is recommended?
    Thanks
    Joyce

    > If the compnay has very few end users to work on SAP i.e. less than 50 users, then x86  is suited.
    > FOr large ended systems that is for large number of users to work on SAP, SPARC is better choice.
    > SPARC is recommended.
    I'm sorry but this is simply not true.
    x86_64 is VERY suited for big systems, we run x86_64 systems with 1000+ users, on Solaris and on Linux.
    Solaris on x86_64 is a very good choice, a mature OS with lots of features (zones, ZFS...) running on affordable hardware.
    SPARC is a RISC architecture, there are even drawbacks in performance if you use e. g. T-series systems (UltraSparc) for ABAP systems and databases (see Oracle Metalink ID 781763.1 - "Migration from fast single threaded CPU machine to CMT UltraSPARC T1 and T2 results in increased CPU reporting and diminished performance").
    So it's a matter of taste and choice - and money.

  • From 7.3 on NT to 8 on Solaris x86?

    Has Oracle ported Oracle8 for Solaris x86?

    Hi,
    usually I expect people to do a little research and I do not give everything chewed.
    Point 4:
    go to the
    <b>Oracle9i Database Migration Release 2 (9.2)</b>
    go to the chapter 3
    <b>Upgrading a Database to the New Oracle9i Release</b>
    go to the point:
    <b>Upgrade the Database Manually</b>
    Exactly from here:
    http://download.oracle.com/docs/cd/B10501_01/server.920/a96530/upgrade.htm#1009200
    Keep in mind
    1) that the <i>EXACT </i>procedure you are following it is not indicated in this manual
    2) you have to think a little ( do you have all the windows services created on the destination system? if not, you have to create them ... )
    3) this procedure is not supported by SAP. It is a valid option but not supported by them. You have to practice until you get all the points correctly

  • Oracle migration from Solaris 64 sparc to Solaris x86-64

    Now that Solaris x86-64 is supported in Netweaver 2004s SR1, I was wondering about the migration path.
    Would this be a heterogeneous migration or a homogeneous migration.
    or to put it another way Export/import to migrate
    or backup/restore????
    No documents exist yet regarding this migration.

    Hello Guys
    Just wanted to ask you whether Migration of SAP system from Solaris SPARC to Solaris x86_64 is possible using the
    backup/restore method.
    I would be grateful if you could share your experience
    Regards

  • Migration from Solaris Sparc server to Solaris  x86

    Hi ,
    I would like to know.
    Migration from SAP ECC6 , Oracle , Solaris Sparc to Ecc6, Oracle, Solaris x86 , Is this consider Heterogeneous or Homogeneous system copy?
    Thanks.
    Best Regards,
    ck chai

    Solaris on SPARC is a BIgEndian platform, Solaris on X86 is LittleEndian - so it's heterogeneous --> you need to use R3load to performa a migration - and you need to have a certified migration consultant on-site to do that migration (http://service.sap.com/osdbmigration --> FAQ).

  • ASE for Solaris x86

    I really need a developers edition of ASE for Solaris x86. The current versions that are available are only for Linux or Windows. Is there anywhere I can get the Solaris x86 version??

    You haven't mentioned which ASE version you're looking for so I'm going to assume a newer/recent version of ASE 15.7 is sufficient ...
    For quite awhile now all ASE downloads (IR, GA, EBF, SPxxx) have contained the entire code line (ie, you don't have to find a GA release and then apply a smaller/delta ebf patch file to get the latest version).
    If you've got access to the EBF downloads @ sybase.com you should be able to download a recent copy of ASE 15.7 for Solaris/x86.  During installation just pick the developer license version (the install will generate a generic *lic file for the developers version).
    While there may be a way to download the file from the SAP website(s), I wouldn't have a clue since a) the SAP websites are poorly-designed/confusing and b) SAP is clamping down pretty hard on what Sybase related downloads are available and to whom.

  • Mounting a Solaris x86 CD/DVD from a remote Windows CD/DVD-ROM drive

    Greetings, all.
    Is it possible to mount a remote Windows CD/DVD-ROM drive? I have the Solaris 10x86 Companion Software DVD sitting in a CD/DVD-ROM drive that's installed on a Windows server on my network. It is shared-out (F:) and the two servers can ping each other. I've also confirmed the NFS services/daemons are running on the Solaris x86 machine. I've tried the following variations but, all have failed to produce successful results:

    I've also tried mounting it at bootup by adding the appropriate entry in the /etc/vfstab file but, this does not work as well. I've tried Google'ing for an answer to my issue but, I haven't been able to find anything that applies directly to what I'm reporting. It's usually chatter about mounting from one UNIX server to another. Any advice from the community would be greatly appreciated.

    After three weeks, you deserve a reply. Windoze does
    not natively support NFS.Also deserves a decent answer...
    There are two ways to do this:
    Install Microsoft's free "Windows Services for UNIX," which includes a Windows NFS server; or
    Install the 'sharity' package (google for it); it provides Solaris systems the ability to mount Windows shares

  • Oracle 8.1.5 Client/WLS/Solaris x86

    has anyone been able to get Oracle's client 8.1.5 running on Solaris x86 in conjunction with WLS to talk to back-end Oracle? Any help would be greatly appreciated.thanks.

    This will not work. We have not built the native libraries to work with
    Solaris on Intel..
    I suggest trying the platform independent type 4 JDBC driver available for
    free from Oracle. It is supported (as is any JDBC driver) with WebLogic
    Server. To download it:
    Go to http://www.oracle.com and select the "Download" option.
    From the resulting page, use the "Select Utility or Driver" dropdown to
    select Oracle JDBC drivers
    From the resulting page, scroll down a little (since SQLJ stuff appears at

  • Install error for Oracle 10g on Solaris x86 64-bit.  NETCA won't run

    Hi All,
    I'm installing Oracle 10.2.0.1 on Solaris x86 64-bit. I run the Oracle installer and all runs well until the NETCA portion of the install. It then errors (error file below). When i attempt to run NETCA outside of the installer i'm getting the same error output. I have verified my OS version and that all dependent packages are installed. I'm not sure what is causing this. Any help would be greatly appriciated.

  • How to upgrade oracle 32 to 64 bit on sun solaris x86 64 bit OS?

    Hi,
    I want to upgrade/convert 32 bit Oracle Database 10.2.0.2 to 64 bit database. Existing 32 bit database is RAC and it is running on Sun Solaris X86 64 bit OS.
    First, I want to know is it possible?
    If yes, then what are the exact steps?

    Hi,
    Such a migration can be done, just follow the steps in Metalink note 62290.1
    It is important to remember that 64-bit database requires more shared pool memory so you should increase your shared pool size.

  • How to integrate a Solaris x86 server on Sun Management Center ?

    Hello people,
    I want to integrate a Solaris x86 server on Sun Management Center platform.
    If I'm not wrong, SunMC doesn't run for Solaris x86, server and client only as console with Java.
    In speat of it, I try to install Sun Management Center 3.0 Agent for Solaris x86.
    It seems to be ok, install packages, but when execute es-setup script, intents to create the following directory:
    /opt/SUNWsymon/base/bin/sparc-sun-solaris2.8
    I supose that in this directory, SunMC will install sparc binary files
    At this point, I can't follow the installation and abort it.
    Can anybody give me ideas to install and integrate my solaris x86 server on SunMC ?
    Thanks

    could you guide please?If you still have a copy of your SunMC media around, the same ["es-inst"|http://docs.sun.com/app/docs/doc/820-2215/command-line-1?l=en&a=view] program you use to install Solaris Agents should work on Linux as well. It autodetects OS type and will install Solaris packages or RPMs as appropriate.

    Hi
    From the Unix prompt enter oemapp console(for v9.x). If you are using earlier versions it is oemapp console (for starting the console) and oemapp dbastudio(for starting dba studio)
    For starting OMS enter: oemctrl start oms.

  • Help with evaluation for Solaris x86

    Hello,
    I would like to evaluate Oracle Identity Manager and Access Manager products at the latest version possible -- the host system(s) are Solaris x86 (SunOS .5.10) Unfortunately, I am having a bit of trouble compiling the list of packages/versions to achieve this for this platform. For instance, on the downloads page it appears that OIM is not available for Solaris x86, not even in older versions(?)
    Thank you in advance,
    Scott

    Hi Scott,
    I'm pretty sure that x86 Solaris is not yet certified to run the Identity Management suite. I've been involved in an evaluation process and we ran it all on RedHat Enterprise Server Release 4 Update 5, without too many problems.
    cheers,
    James

  • Core 2 Duo and solaris x86 11/06 works for me

    This is FYI, since I seen (and posted) problems, but I haven't seen the solution posted.
    I have successfully gotten solaris x86 11/06 to install and run on my core 2 duo machine. I had tried solaris x86 06/06, but I could only run in 32bit mode until patch 118855-19 was installed. It looks like 118855-33 is the baseline for 11/06.
    With 06/06 I had to edit the grub command and add " kernel/unix" to the end of the 2nd line. This would force 32 bit mode rather than 64 bit. If I tried 64 bit, it would enter an endless reboot cycle. Once I installed the patch to 118855-19 I could run solaris 10 06/06 in 64 bit mode without issue.
    Again, since solaris 10 11/06 is at 118855-33, it runs on my core2 machine straight from the install.
    Hope this helps

    On a laptop there is little point with running a 64-bit operating system unless it physically has more than 4gb of ram, or if you are processing datasets exceeding 4GB of ram. Unless you're into assembly or use Solaris for some reason to manipulate media, little is to be gained by using 64-bit versions if anything. The increased pointer, integer, and padding causes more memory to use for the same software, most software on 64-bit operating systems runs in 32-bit mode because there is no need to have 16 exabyte memory addressing capability for anything but media encoders, giant databases, or extremely bloated single-threaded software. Sun Java Creator takes a heck of a lot of ram, but even at peak it's still under 4GB. If you move files bigger than 4GB, the ability to memory map all 4096MB might have less overhead on a 64-bit operating system, but generally from an end-user perspective, especially on a fast Intel or Opteron system, you won't notice the difference much. Solaris is bi-arch, a large chunk of Windows Vista and XP x64 is bi-arch, and most of FreeBSD and Linux are bi-arch in 64-bit versions, as I said, no point in making everything 64-bit. 64-bit device drivers is an issue for every OS, you should stick with 32-bit on a laptop, and hold off on desktops unless you need extended assembly registers available only in 64-bit mode.
