Oracle 9i backup onto Oracle 10g

Hi All,
Is it possible to restore the SAP backup taken in Oracle 9.i onto the Oracle 10g.
If possbile, can anyone share the documents for the same?
Thanks in advance,
DVRK

> You won't be able to use 9i DBFs on a 10g DB. You need to go 9i -> 9i then upgrade your "new" DB to 10g.
This is not true as stated. There is no difference in upgrading an installed 9.2 database (as shutdown, install 10.2 software and upgrade) and copying files over and doing the upgrade directly.
See (as written already)
Note 932722 - Upgrade to Oracle 10.2 during a database copy

  • Oracle RAC and Oracle Secure Backup Express

    I am building a new RAC environment - 7-Nodes on Linux.
    We are very interested in reviewing Oracle Secure Backup, possible Oracle Secure Backup Express.
    My understanding about Oracle Secur eBackup Express is it is licensed "free" as long as you are working with a single tape drive.
    Does anyone know - does this apply to RAC as well?
    Thanks

    Please refer to the OSB licensing document for
    specific differences between OSB-XE and OSB:
    http://download-west.oracle.com/docs/cd/B32520_01/doc/
    license.101/b25528/toc.htm
    In general, we recommend you backup each RAC node to
    insure all local files are protected which would mean
    the OSB-XE edition would not be recommended since
    OSB-XE is backup of one server.Thank you - I will review this.
    .. and your White Papers regarding performance were just what I was looking for.

  • Oracle 10g Backup in Oracle 9i

    i have oracle 10g database and i take oracle 10g dmp backup from there. now i want to run it in oracle 9i, i gives error.
    How can i take the dmp backup which is compatiable in oracle 9i.

    hi,
    as told by maran
    the binadries are in bin .. you need oracle 9i binaries for that.. or try copying oracle 9i exp.exe to 10g bin... but don't do in production environment.
    try in your test.

    Did you archive the current log file which i mentioned in the earlier post
    if so and if you the archived log
    Shutdown the DB
    Rename the file you copied
    move the D:\oradata\*.dbf(whihc was backed up by you)in the original directory and

    h1. Using Different Releases and Versions of Export
    Whenever you are moving data between different releases of the Oracle database, the following basic rules apply:
    The Import utility and the database to which data is being imported (the target database) must be the same version.
    The version of the Export utility must be equal to the earliest version of the source or target database.
    For example, to create an export file for an import into a later release database, use a version of the Export utility that is equal to the source database. Conversely, to create an export file for an import into an earlier release database, use a version of the Export utility that is equal to the version of the target database.
    In general, you can use the Export utility from any Oracle8 release to export from an Oracle9i server and create an Oracle8 export file. See Creating Oracle Release 8.0 Export Files from an Oracle9i Database.

  • Unable to see Oracle Secure Backup Selections in EM (10g-10.2.0.1)

    I cannot see the Oracle Secure Backup choices on the maintenance tab page.
    I see Backup/Recovery and Backup/Recovery Settings but no third column Oracle Secure Backup.
    I logon to EM as SYS.
    Any ideas ?
    Thanks

    If you go to the maintenance tab on your EM, are there a couple of links under "Oracle Secure Backup" heading. I don't have this showing on my page. If I look at any of the Oracle demo pages I see it.
    Like I said it is a feature of 10gR2....which I have.

  • How to include Date for backup of Oracle in a script !!! LINUX

    I don't have my linux system handy to debug, but what you want would be something like:
    expdp ..... dumpfile=exp_`date`.logThe reverse single quote (I don't know the official term, but it's the character just to the left of the one/exclamation on a US keyboard) tells the shell to substitute the value returned by the command enclosed by the marks. In the example above, it would substitute the value returned by the "date" command. That command has many, many arguments to control the format of what is returned. Look them up an any good nix reference, or just "man date".  (As for any good nix reference, you should at a minimum have a copy of "Unix In A Nutshell" on your desk.)

  • How to perform a Oracle-Offline-Backup started from within SAP in Cluster

    Hello,
    I didn't find a solution on web (at SAP/SUN/newsgroups) for the following problem:
    environment
    - offline-backup of Oracle-database (database of an SAP-R/3 ERP-system)
    - Sun Cluster 3.1 environment (SUNW.oracle_server:3.1, SUNW.oracle_listener:3.1, SUNW.sap_ci_v2)
    - backup should be started from within the SAP R/3 scheduler (SAP transaction: db13)
    - Oracle-RMAN-backup with Legato networker 7.1
    - SID of SAP-system: Q22
    problem
    When SAP starts the backup-job (scheduler: db13, type: Full database offline backup >> option: offline_force) the brbackup commands shuts down the database and starts RMAN-backup. But then the Sun Cluster sees that the database is down and starts it up. This action of the cluster crashes the backup.
    Now I found a tricky solution for that problem:
    1.
    Install sudo because the following script will not be run as root...
    2.
    run visudo and add this line (the scheduler db13 uses the OS-user <SID>adm)
    q22adm ALL=NOPASSWD: /usr/cluster/bin/
    3.
    make a shell-script which should reside on a global mount:
    /sapmnt/Q22/MB/offline_backup_Q22.sh
    #!/bin/sh
    /usr/local/bin/sudo /usr/cluster/bin/scswitch -n -j Q22db-srv
    sleep 10
    /usr/sap/Q22/SYS/exe/run/brbackup -u / -c force -t offline_force -m full -p initQ22rmanoffline.sap
    /usr/local/bin/sudo /usr/cluster/bin/scswitch -e -j Q22db-srv
    4.
    edit the table sapr3.sxpgcotabe in the Oracle-database and add an entry like:
    NAME: ZOFFLINEBACKUP_Q22
    OPSYSTEM: ANYOS
    OPCOMMAND: /sapmnt/Q22/MB/offline_backup_Q22.sh
    this is not possible via SAP, use Oracle-tools!
    5.
    edit table sdbac via SAP-transaction se16, select DBSYS=ORACLE and add an entry like:
    SHORTCUT ZOFF
    DBSYS ORACLE
    OPSYS *
    LANGUAGE E
    SHORTNAM FullOffClu
    LONGNAME Full database offline backup >SunCluster
    HOST $DBHOST
    CTYPE EXT
    CNAME ZOFFLINEBACKUP_Q22
    6. Schedule the offline-backup via SAP-transaction (new type available: Full database offline backup >SunCluster)
    I hope that maybe helps someone...

  • RMAN / backup.  oracle 9 vs. oracle 10

    My colleague mentioned a while ago that we had to investigate RMAN &/or a backup client, "because in oracle 10, when doing an export of a live db, oracle does not switch into "single user mode" like it did in 9. So we couldn't have 100% faith in our .dmp file."
    I'd like to do some further research on this, but looking through the "Oracle 10 Complete reference" and googling - I don't see any information about it. Has anyone here dealt with this or know of a link I should see?
    Finally... Does anyone know if an RMAN backup for Oracle 10 accounts for any "in progres" transactions?
    Thanks in advance,
    Mike.

    Oracle, itself, doesn't switch to single user mode.
    Your colleague might have been talking of scripts which shutdown and restart the
    database in restricted mode to run an export of the database.
    RMAN backups as in 8.0/8i/9i/10g (or EBU in Oracle 7) and scripted (aka
    "user managed") backups are all physical backups. They take database blocks
    "as they are". Conceptually, the datafile backups aren't aware of active transactions.
    It is the redo stream in the archivelogs that is required for you to be able to restore
    and recreate a consistent database image.

  • Problems doing backup in Oracle RAC

    I am working with ORacle RAC, version 10G. That thing about Oracle RAC is completely new for me. There is three databases, I'm doing backups using OEM, but here is the problem. We have defined the directory /backup in both nodes. The problem that I have is when I do the backup it's done in one node, example, today I do the backup, it's done in NODE1/backup. The next time I'm going to do a new backup by any reason the aplication (OEM) is pointing to the NODE2/backup. So here is the problem, if I need to use the first backup, I can't use it, because OEM is pointing to NODE2 instead on NODE1. My question is, how can I set the node, with OEM where I want to do backup or retrieve a prevoius backup?
    Thanks for your help.

    Thanks a lot forn your suggestion, but I think I should give you more details about my doubt.
    The following are the steps for a backup with Oracle Enterprise Manager
    steps
    Thru OEM
    Maintenance
    BACKUP/RECOVERY
    Schedule Backup
    Archive Logs (Whole Database, etc.)
    Then here I click override current settings, by the way, the default is spaces, so I type /backup, but problem is that directory exist in both node, Node1 and Node2, I'm working with oracle 10G, RAC, in a operating system AIX 5.3.
    Then I click Compressed Backup Set, and that's all what I'm doing. But the problem is, sometimes the backup is done in Node1 and other in Node2. And if I need to restore from any previous backup that was done in NODE2, and the application (OEM) is pointing to NODE1, and can not use that previous backup. So, my question is how can I control this, using OEM. I mean, How can I set the Node, to identify in which node the backup will be done, or in which node is the backup I'm going to restore.
    Thanks again

  • Oracle reports 6i to Oracle forms 10g migration

    Hi,
    I have .rdf files which were created on Oracle Reports 6i. I would like to migrate the .rdf files into Oracle Reports module which is present as a part of Oracle Forms 10g to generate PDF output.
    Please let me know the detailed steps to be followed as I am a total newbie. Also I need to generate these reports on demand from a java 5 application (JSF 2.0).
    Currently for ORacle reports 6i, I have the following code in my java application
    rwrun60.exe g:\tomcat33\webapps\reports\web-inf\src\null userid=***/*** destype=FILE desformat="pdf" paramform=NO printjob=NO batch=YES desname=temp.pdf
    1. What would be the equivalent for reports in ORacle Forms 10g ? I know there is an Oracle Apps server where ther report services reside. How to I invoke my report from my java application (residing on a weblogic server 10.3.6)?
    2. What ould I do with the 6i .rdf files to upgrade them to 10g ?

    I am trying to call an Oracle report i.e .rdf (which is located on the Oracle  App Server) from my java EE 5 (JSF) application. The Oracle  App server is Oracle Application Server 10g Release 2. I assume Oracle report generation capability is available in this release.  I need to invoke the report from my Java JSF application on demand (whenever the user clicks a button on the web browser page, the report should appear on the browser as PDF) . My java application resides on Linux weblogic server.
    Please let me know how it can be done ? I see rwclient.sh and another method to directly invoke using a URL. How do I do it on java, would a request.redirect() to the URL work ?
    Also for hiding the params in the URL. keys need to be configured on the Oracle server right ?
    Also if we use rwclient.sh or the URL based invocation, would there be any issue in concurrency when multiple users request the same report at the same time ?

  • Oracle report from 6i to 10g

    hi all,
    We try to move oracle report from 6i to 10g. however we found that the report's record ordering is different.
    The case is that, the record in report is ordered according to the attribute "break order".
    There is no "order by" in sql".
    It runs without problems in 6i, but in 10g , the ordering of the record has no ordering.
    Please help to solve the problems or give some advice. Thanks.

    Break order property only works for ordering in break groups. For other groups (like the lowest level group) you have to use order by in your SQL.
    That was also the case in 6i, so you may just have been lucky that it worked at all.
    This is from the Help:
    The Break Order property is the order in which to display the column's values. This property applies only to columns that identify distinct values of user-created groups (i.e., break groups ). The order of column values in a default group is determined by the ORDER BY clause of the query for SQL queries
