Migration from 32-bit to 64-bit on Oracle 9.2.0.5

Hi guys.
I have two question for migration 32 bit to 64 (x86_64) bits on Oracle 9.2.0.5 for SAP 4.7 Enterprise?
1.- When i migrated 32 bits to 64 (x86_64) bits is necesary migrated to Oracle 10 ?
In the note SAP Note 960769 - Windows: Migration from 32-bit to 64-bit (x86_64), say that, pag 4:
" Oracle:
=====================================
On Windows Server 2003 X86_64 (64-bit), you may only use Oracle 10g Release 2 (10.2) software for X86_64 (64-bit) as a database. Note 949116 describes the installation (homogenous system copy) of old products that were not originally released on Oracle 10g Release 2 (10.2). If you want to make the copy using the backup/restore procedure, for which the source database was not yet upgraded to Oracle 10.2, see Note 932722"
But, in the pam matrix say that support for 9.2.
I confused for the information.
2.- In the case that is not necessary to migrate to oracle 10, i can execute the migration to 64 bits the SAP 4.7 with the procedure Backup/Restore?
I don´t have the new server, the server for the migration is the same. The procedure you want to follow is:
1.- Backup Offline all server.
2.- Delete the server, i install the server on Windows 2003 64 bits.
3.- Install SAP 4.7 on kernel 64 bits.
4.- Restore de backup offline (only data): datafiles, archive log, redo log.
Aprecciated for the help.
Best regards,
Desiré

Hi,
According to Note:814834
#Note that there is currently no 64-bit support for the x86_64 platform
for Oracle 9.2 because Oracle does not provide a 64-bit DB client for this purpose,
and, in addition, 64-bit operation of the DB server is not supported.
This means that this DB version can only be used in conjunction with SAP components on
Windows 32-bit on x86_64 hardware in 32-bit mode.
For more information, refer to the "Oracle" section in the note.
Furthermore, it states 32bit SAP instance can connect ot a 32 bit Oracle 9.2 or 10.2 database instance.
So for your case, its better to upgrade your current database to Oracle 10.2 and then proceed with migration.

  • Tuxedo Migration from Tuxedo 9.1 32 bit to Tuxedo 9.1 64 bit

    Hi All,
    Please tell me how to go for Tuxedo Migration from Tuxedo 9.1 32 bit to Tuxedo 9.1 64 bit. O.S. is IBM AIX 5.3 64 bit What are the prerequisite, and how to go for that. Please tell hoe to go for the same. Please mail at [email protected]

    Ravi,
    You will need to download 64-bit AIX binaries for Tuxedo 9.1.
    Since 64-bit object files and libraries cannot be combined with 32-bit object files and libraries in the same executable, you will also need to obtain 64-bit versions of any database or other third party software that is linked with your Tuxedo application. (If you are using Oracle database, 64-bit and 32-bit support is combined in a single download, and you will just need to change $ORACLE_HOME/lib32 to $ORACLE_HOME/lib in your makefiles.)
    Once this is done, you will need to rebuild your Tuxedo servers, clients, and TMS processes.
    If you use buildclient and buildserver to compile all files, then you may not need to change anything else. If you call the compiler directly to compile source files into object files, then you will need to add additional flags for 64-bit compilation. If your makefiles are well-coded, you might just need to change CFLAGS in one place. Look at the output of "buildclient -v" for a simple client on the 32-bit system and on the 64-bit system to see which additional flags might be needed.
    When your application is compiled in 64-bit mode, you just need to test it out to ensure that the application does not have any implicit 32-bit dependencies such as assuming that a "long" is the same as an "int".

  • Re: Migration from Sysbase Adaptive Server 11.5 to Oracle 8.0.6

    I had a problem when using Oracle Migration Workbench to migrate a database from Migration from Sybase Adaptive Server 11.5 to Oracle 8.0.6 in NT environment.
    It contains only 8 tables.
    Firstly, it captured well the source database from Sybase. But It hang on every times when mapping tables in this database to Oracle.
    Is there anyone experienced with this problem?
    By the way, I would like to know that which way (tool) is the best one to migrate
    A system from Sybase Adaptive Server 11.5 to Oracle 8.0.6
    Any idea will be very appreciated?

  • SQL Devloper Migration from SQL SerProcedurs created as Functions in Oracle

    Hi All,
    This is the first time I am using SQL Deveoper to migrate SQL Server database to Oracle.
    I have SQL Developer 3 and I did migration from SQL Sever 2008 to Oracle 10g using online migration.
    Everything was done perfectly, but there are some extra tables created in Oracle which are not present in SQL Server database.
    And also I observed lot of programs which are stored procedures in SQL Server are converted as functions in Oracle.
    Does someone knows how to fix this problem.
    Thanks

    Hi,
    A SQL*Server stored procedure can be converted to an Oracle function depending on how it is written and what it is doing. In the documentation -
    Oracle® SQL Developer
    Supplementary Information for Microsoft SQL Server and
    Sybase Adaptive Server Migrations
    In Chapter 3 in the section -
    3.4.2 Function
    It says under Table 3-6 -
    In Microsoft SQL Server or Sybase
    Adaptive Server, you can convert a stored
    procedure to a function in Oracle because
    the stored procedure in Microsoft SQL
    Server or Sybase Adaptive Server can
    RETURN an integer value to the calling
    routine using a RETURN statement. A
    stored procedure returns a status value to
    the calling routine even in the absence of
    a RETURN statement. The returned status
    is equal to ZERO if the procedure
    execution is successful or NON-ZERO if
    the procedure fails for some reason. The
    RETURN statement can return only
    integer values
    And what tables do you see in oracle that are not there in SQL*Server ? Some tables are created as part of the migration as they are needed to have the same functionality as in SQL*Server.
    Does your migrated Oracle database work in the same way as the SQL*Server database ? If not, then please give use specific examples and we can follow up.

  • Oracle Application R12.1.1 Migration from Solaris to Linux 64-bit

    Hi,
    Our existing System:
    On Solaris 9:
    Database 10.2.0.2
    EBS 11.5.10.2
    We are planning to Upgrade the system to
    Database 11.2.0.3
    EBS R12.1.3
    We also want to migrate to RHEL 5 64-bit.
    Please let me know if you have experience with respect to the following issues:
    1. Can I use *Application Tier Platform Migration with Oracle E-Business Suite Release 12 [ID 438086.1]* as reference for my scenario? The document mentions that only Windows is supported as the source platform.
    2. When they copy APPL_TOP from source to target - how the binaries from source operating system will work on target operating system? Else, are they platform independent?
    3. Will the following approach work?
    a. Migrate 10.2.0.2 database from source (Solaris) to target (RHEL 5 64-bit).
    b. Upgrade 10.2.0.2 database to 11.2.0.3 on target.
    c. Install R12.1.1 in upgrade mode on target.
    d. Retrofit customization.
    e. Upgrade R12.1.1 to R12.1.3
    Also can you recommend best practise for Migrating database?
    Thanks in advance.

    Note: Application Tier Platform Migration with Oracle E-Business Suite Release 12 (Doc ID 438086.1) reads: "The instructions in this document are for migration to a target UNIX/Linux platform. At present, Windows is only supported as a source platform."
    Note the word SOURCE. So the restriction is Windows cannot be used as a TARGET platform, but other platforms can.
    The content of the APPL_TOP is re-used in the Target environment, except for the binaries; these are delivered by applying the "customer-specific update" as in Note : Application Tier Platform Migration with Oracle E-Business Suite Release 12 (Doc ID 438086.1)
    For information on the database migration check Note: 10g Release 2 Export/Import Process for Oracle Applications Release 11i (Doc ID 362205.1) and http://blogs.oracle.com/stevenChan/entry/migrating_ebusiness_suite_databases_between_platfo
    The scenario seems OK, but needs to be tested of course.

  • OS Migration from Windows 2003 cluster  to Windows 2008 R2 MSCS

    We want to go for windows 2008 R2 server ( 64-Bit)  MSCS by migrating from windows 2003 Cluster ( 32- Bit) . We are running on ECC 6.0 and oracle 10.2.0.2 DB.
    Is it possible ?
    Is it traditional System copy if so how to migrate the cluster ?
    Regards

    > 2. If the oracle version is 10.2.0.2 then does it will support Windows 2008 R2.
    You need at least 10.2.0.4 (you need to install that version with a separate DVD, you can't install with the normal Oracle DVD (10.2.0.1). See
    Note 1303262 - Oracle on Windows Server 2008
    Be aware of the fact that the normal standard support for 10.2.x is ending at end of july (you'll have to pay an extra maintenance fee if you continue to run that version) - see
    Note 1110995 - Extended maintenance for Oracle Version 10.2
    So if you now do a system copy to new hardware with a new os anyway, I would upgrade to 11.2.

  • Migration path from 10.1.3.3.0 to Oracle TopLink 11g: Technical Preview 2 ?

    What is needed to migrate from 10.1.3.3.0 to Oracle TopLink 11g Preview 2?
    Does using Java 5 and swapping the Jar files are enough?
    Can I use as is all the configurations generated by TopLink Workbench 10.1.3.3.0?
    What is working in 10.1.3.3.0 that is not yet or will not be working in Oracle TopLink 11g?

    If you open the project in the 11g preview it will automatically update the metadata and generate the deployment XML in the new format. Alternatively you should be able to open the 10.1.3.3 metadata in the 11g preview's runtime.
    The biggest issue you may encounter in the upgrade besides replacing the libraries and ensuring you are using JDK5 is the removal of the code deprecated in previous releases.

  • Migrating from Centura/Gupta to Oracle forms

    Hi
    I work at an organistion that is the result of a merger, we have two main bespoke systems, one in Oracle Forms which has recently been upgraded to the web based version (6.5) and a second written in Gupta / Centura SQL Windows client server. Both use Oracle databases thought the Centura application is still on 8i.
    We want to move to Forms over time but will have to run both for a while and would like to try and run them as more of a single system in the interim. e.g a single security system so users can move from one to the other without having to use 2 userids & passwords. My initial investigations suggest this isn't going to be easy.
    I wondered if anyone had any experience/ tips, or could point me at any useful resources.
    Thanks

  • Migration from 8.3 to 11.1.2.1

    We are planning to migrate from Hyperion performance suite 8.3 to Oracle EPM 11.1.2.1 through Migration utility. But we have 2 different source system. is that possibel to migrate 2 source system into one target system. 2 sources system uses the oracle source repository.
    Thanks in advance

    Hi Krishna,
    This is not a Distributed environment. Here the two source systems are different standalone applications. One is Unix and the other is solaris. Still now they ae using two different environments seperatley, now we are planning to migrate these two different source systems into a single target system.
    Our questions is as it is two standalone applications it has its own foundation and product deployed databases (both uses oracle Repository) will it make any issuses while migrating 2 foundation services databases to a single foundation services database (11.1.2.1) as the same way two Brio deployed databases to single target IR database (11.1.2.1).
    Thanks,

  • Migration from Sun Java System Portal Server to the Oracle Portal

    Hi, I'm in charge of evaluate the viability of a project that comprises the migration from Sun Java System Portal Server to the Oracle Portal. so I'm wondering if there is a kind of out of box migration tool in Oracle Portal or exists some guidelines to do the migration. In the other hand there is the option of migrate from Sun Java System Portal Server to Oracle WebCenter?
    Thanks in advance!

    The migration path for Sun Portal Server is Oracle WebCenter Suite. WebCenter is a significantly different architecture so there are no tools planned for the migration. However, we do plan to document and publish a whitepaper once we've assisted a few of the initial customer migrations.

  • Migrating from jserv to OC4J

  • Migrating from JServ to OC4J: problems with XSQLServlet configuration

    I'm trying to move an application using xsql pages from 9iAS to 10g (9.04). Development is currently done under JDev9 (9.02) an its OC4J standalone server.
    I guess I've done most of the configurations, since the application is working correctly now, BUT only with the connections defined statically in the XSQLConfig.xml of the XSQLServlet. On JServ, we implemented our own connection manager to pass our connections to the XSQLServlet as defined by the <connection-manager><factory> tag. Now, under OC4J, this no longer works:
    The log files tells:
    Failed to create custom connection manager factory: "our.connection.manager.factory": Using default.
    And with the default one, we get of course the 'cannot acquire database connection' error message which is ok, since we're not using one of those defined under XSQLConfig.xml...
    Background: Our connection manager is contained in a jar file with many other classes. These are visible to the 2 applications ("P" and "T") we're running successfully under OC4J Standalone. As I interprete the message as the XSQLServlet not being able to create an instance of our ConnectionManager, I guess I missed somewhere an library or classpath entry??
    Many thanx for any hints!
