Thanks in Advance.You can use manual or using exp/imp can upgrade your database.
1.Take cold backup from 9i database.
2.Install 10g software and create need directories and restore cold backup
3.Startup database with upgrade option
sqlplus "/as sysdba"
startup upgrade pfile='pfile_location'
@$ORACLE_HOME/rdbms/admin/catupgrd.sql;
shutdown immediate;
startup pfile='pfile_location'
@$ORACLE_HOME/rdbms/admin/utlrp.sql;For more information refer

  • Error after Oracle Migration from DMTS into LMTS

    Hello ,
    I'm sorry, I posted my question again from ABAP General into this forum ABAP Dictionary. I think that here someone can help me in order to proceed with my job in the Development and in production system.
    We are using SAP R/3 4.6C, with SAP kernel 2271, Oracle 9.2.0.5 and HP-UX 11.23
    I did the Oracle migration from dictionary into locally managed tablespaces on the QTS system (and before that the same migration on a separate system as a copy from production):
    1. export data and index tablespace with Oracle export command (exp: for PSAPCLUD and PSAPCLUI)
    2. import into file for creation of indexes
    3. Drop the data and corresponding index tablesspace with brtools - brspace
    4. recreate the tablespaces with sapdba or with sqlplus (using the ddl scripts created before dropping the tablespaces) - - I think is my problem
    5. import the data with Oracle import command
    6. import the indexes from the previously created sql file
    7. check optimizer statistics, analyze and next extents
    But there is one problem.
    Because I have also used the sapdba and ddl sql for recreating the tablespaces, I didn't specify the SAP data class for the newly created tablespace.
    And in the tables TAORA, IAORA and DDART (what is very unclear for me) 3 rows missing for the USER1, TEMP and ??? data class.
    If you try to import some transport in the corresponding tablespace which data class is missing an error ocur.
    I have read the Note 646681 - Reorganizing tables with BRSPACE, and I saw the part: If the <reorg_tsp> tablespace contains any of the following tables: SDBAH,SDBAD,DBAML,DBATL,MLICHECK,TGORA,IGORA,TSORA,TAORA, IAORA,SVERS,DD02L,DD09L,DDNTT,DDART,DARTT or SAPLIKEY (SAPLIKEY is only available in NetWeaver 2004s or higher), then you should move them to the tablespace <aux_tsp> by online reorganization using BRSPACE:
    brspace -f tbreorg -t <table_list> -n <aux_tsp>
    Do you have the same problem?
    Do you know how I can solve the problem now after the hole migration was done?
    How can I dedicate tablespace data class?
    Is it enought to just enter the same rows into the TAORA, IAORA and DDART?
    Thanks,
    Many regards,
    Ruzica

    Apparently you are trying to mix 32-bit code and 64-bit code. You must ensure that the 32-bit or 64-bit option is used consistently on every command, compiling and linking. The form of the option can depend on the version of the C compiler you are using, and whether you are on an x86 or sparc system. Consult the Pro*C and C compiler documentation.

  • Does theJ2EE migration kit support migrating from Oracle9 iAS?

    Hi,
    We currently have an application based on Oracle9 iAS.
    1) Does the J2EE migration kit support migrating from Oracle J2EE to SAP J2EE?
    2) If the answer is NO and since the documentation doesn't mention Oracle, I am wondering if SAP is planning on including support for migrating from Oracle too?
    Regards,
    Tobi

    Hello Anirban,
    what kind of projects are you trying to migrate to NWDS?
    The Migration Kit (Plug-In) in its surrent version supports migration of projects from IBM, JBoss, BEA to SAP - on the same Java EE technology stack level! If you want to migrate SAP 6.40 (J2EE 1.3) projects to SAP CE (Java EE 5), there is a support in the SAP NWDS to do that. You can start importing your "old" projects by saying "migrate projects" in the import statement of the IDE.
    Try it out!
    In case you should encouner difficulties, shoot me a mail!
    Cheers, Goran

  • Migration from Oracle9i to Oracle 10g

    Hi All,
    Is anyone aware of exact differences between Oracle 9i and 10G?
    Can some one point me to any URL where I can find exact list of difference between Oracle 9i and 10G?
    Thanks in advance.
    Regards
    Ninad K

    Hi,
    There are so many differences.
    You can start to have a look to the doc: Oracle® Database New Features Guide 10g Release 2 (10.2)
    http://download.oracle.com/docs/cd/B19306_01/server.102/b14214/toc.htm
    I hope it helps you.

  • Oracle Migration from 8i (WE8ISO8859P1) to 9i (Unicode)

    We have a database in oracle8i with
    NLS_LANGUAGE AMERICAN
    NLS_CHARACTERSET WE8ISO8859P1
    NLS_NCHAR_CHARACTERSET WE8ISO8859P1
    The character set WE8ISO8859P1 does not support GREEK language.
    The user inserts/modifies records in this databse from the front-end. The front end installed in the client machine has the following setting:
    Control Panel->Regional settings ->Advanced ->
    Language for non-unicode programs = Greek
    Oracle client installed in English
    Greek characters have been inserted/updated into this database and retrieved and displayed correctly by the GUI.
    Note: Greek data has been inserted into WE8ISO8859P1 database which does not support Greek characters.
    hence the actual data that is stored in the database are not Greek. Only while displaying, they are getting converted into Greek characters due to the settings in the client machine.
    Requirement: Migrate the database to Oracle 9i Unicode.
    While migration, we need to eliminate any data discrepancy and make sure the data in the Unicode dabase is in Greek.
    Can you suggest us a method to do the migration to avoid the above problem, and a way to check what are the characters that are stored in the database and help us identify if they are real Greek characters.

    There is no way to do a "cold" export, since Oracle needs to access the database to do the export. The closest you could come would be to shutdown the listener on the 81 box, shut it down, then open it in restricted mode and do your export.
    There is no need to copy archive logs, redo logs, or anything other than the export dump file.
    I'm not sure how big the differences are between NT and Win2k in terms of O/S file structures. If the two are fully compatible, you if you can install 8i on the Win2k machine as well as 9, then you could do something like:
    Copy your last backup, plus all archive logs to the Win2k machine.
    Do a recovery there to re-create the 8i database using the 8i Oracle install.
    Shut down the 8i database, and open it under the 9 install and do an inplace migration.

  • Oracle migration from solaris to AIX

    Hi,
    We have a activity of a migration of oracle 9i Solaris database (800G in size) to AIX oracle 10g database, we use RMAN and exp/imp as a backup method. What are the efficient and fastest methods to do this and i what way?
    Thanks
    Jaffy

    Hi
    As your database is large so try transportable tablespace features for different platform migration.If endian format is same you don't need to use RMAN for datafile conversion.If endian format is different you need to convert datafile.
    You will get information about supported platform from V$TRANSPORTABLE_PLATFORM .

  • Oracle migration from Solaris to Win

    Dear All,
    I need to create a test database, so I have to migrate a 10.2.0.1 DB from Solaris (64 bit) to Windows 2003 Standrard Server (32 bit).
    The problem is that I cannot see anything related to this Win version in the v$transportable_platform view, the only one near to this is "Microsoft Windows IA (32-bit)"... This is not an IA machine, so I assume that my only way to transport is exp/imp... There is 100GB of data, so any help would be highly appreciated related to the speed...
    Thanks,
    Franky

    Windows Server 2003 32bit (based on x86) means Oracle generic software for Windows 32bit. You can use RMAN's crossplatform-feature, although a direct conversion doesn't work (because of different endianess), you need some extra steps. Refer to this document:

  • Oracle Migration from 7.3.4 to 9i across different operating systems

    Hi,
    I have a running production Oracle database on an Windows NT. The requirement is to migrate to 9i database which is on a Windows 2000 box. What are the best solution to handle the situation. One thing I can think of is an Export/Import but can i have more suggestions. Since the export/import takes longer other methods are sought
    Thanks
    Sachin

    ah right. I think that one of the problem that you can have is with the character set from one version to another because the national character set in 9i differs than before. I recommend you to do the upgrade using national character set UTF8 first and after AL16UTF16 after in databases separetly and probe your application.

  • 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

  • Migrating from oracle8i to oracle10g

    how to migrate oracle8i to oracle10g

    Hello,
    Check with Application Vendor, majority of Third Party Applications are Schema Based only, so it will be easier to perform schema Export from 8i and import in 10g or 11g (As per Apps to DB Certification)
    Seems like you have 8i version which is very Old and it may need cleanup too, which will be done as part of Export Import and you can reclaim additional Space assigned to Datafiles (In case you had lots of data and deleted those - and not able to remove those due to HighWater Mark Issue)

  • Migration from Oracle 9i 32 bit to Oracle 10G 64 bit on Windows 2003 Server

    I am working on migrating Oracle 9i 32 bit to Oracle 10G 64 bit on Windows 2003 from Old server to new server. We have db around 500 GB and 3 schemas. I installed Oracle 10G on new server, created tablespaces, schema's blah blah and now doing export and import at schema level from old server to new server.
    Import is taking more than 4 to 5 hours on new server. My manager is saying, window time is bit longer and he wants me to try possiblities to make this process faster. Can some one help me on this, to use the best possible method to complete this process faster?
    Will below step work, if I try?
    If I install, oracle 9i and 10g both on new server in different home directories and take the hot backup from old machine and restore on new machine in 9i home directory and use the upgrade configuration assistant from 10g and do the upgrade? Pls advice.
    Thanks in advance,

    It looks good.
    I have one question in below steps:
    To migrate an Oracle9i or older database to an Oracle Database 10g Release 1 (10.1) database for 64-bit Windows:
    1 Perform steps 1 - 11 in "Migrating an Oracle Database 10g Release 1 (10.1) Database".
    2 Shut down the database on the 64-bit computer:
    SQL> SHUTDOWN IMMEDIATE;
    3 Start the database migration:
    SQL> STARTUP MIGRATE;
    4 Migrate the database as described in Chapter 3, "Upgrading a Database to the New Oracle Database 10g Release" in Oracle Database Upgrade Guide.
    In step 4, it says, migrate database as described in chapter 3. In chapter 3, it says, to do the upgrade the process using dbca or manually. Pls confirm whether do the upgrade process after issuing startup migrate or not.
    Thanks in advance.

  • Out of memory error in migrating from mysql to oracle

    Hi,
    I'm trying migrate from mysql to oracle9i. The hardware and software requirements are matching or even much higher than mentioned in the documentation. I have installed OMWB is properly(hope so). When I try to migrate the desired database from mysql to oracle, the repository, the Oracle model are created successfully. But while migrating data, say for around 35000 rows insertion everything works pretty fine. But after sometime, the migration stops and no error or anything appears in the screen.And in the Errorlog I get "OutOfMemoryError".
    I tried to migrate single table also. But I still get this problem after sometime. The tables may contain from 10 - 130000 rows...
    I even tried to change the %JRE..% memory value to 64M or 128M in the omwb.bat file and the O/s is Microsoft Windows XP, RAM 256MB.
    Any help is much appreciated.
    Thanks in advance.

    Hi Viji,
    did the message in the error.log provide any extra information? For example, was the OutOfMemory error prefixed with a string
    like "cannot create new native thread" ? My suggestion to workaround the problem would have been to increase the JVM heap size to 128
    but this appears to have been unsuccessful for you. Can you send a mail to the Migration Workbench support services
    ([email protected]) explaining the problem, and attach the full error.log file please ? (please also copy me on the mail).
    In the meantime, you can workaround this by migrating the schema only (there is a switch on step 3 of the migration wizard asking:
    "Do you want to migrate the table data to Oracle?" - just select the "No" option). When the schema has migrated, you can then use the
    offline data loading facility to migrate the data. This uses data extraction scripts and SDQL*Loader to migrate the data to the target
    Oracle database.You can learn more about the offline data loading facility from the plugins referenceguide (from the Help menu in
    the Migration Workbench).
    I hope this helps,
    Tom.

  • "Default " problem while migrating from mysql to oracle.

    I'm migrating from mysql3.23 to oracle9i via the OMWB tool.While migrating i'm getting an error message "Failed to create default for the table <table>:ora00907 missing right parenthesis".This error is due to the difference in the syntax used for the keyword "default" in mysql and oracle.In mysql we have to give after the Not Null option whereas in oracle we have to give before Not Null.
    The problem is i'm migrating via the OWMB tool.Is is possible to handle this error with the help of tool itself.
    Thanks
