Duplicate single instance (11.2.0.2) database to RAC (11.2.0.3)

Hi Experts,
I have to duplicate my PROD database which is a single instance in to RAC TEST database. Please give me procedure to do that.
Prod database - Single Instance - 11.2.0.2
TEST Database - Need to create dummy instance in RAC and restore the PROD data - 11.2.0.3
Note: RMAN duplicate failed due to different patch level.
Regards,
Salai

You CAN restore an 11.2.0.2 database backup into an 11.2.0.3 ORACLE_HOME.  You will need to upgrade the database (data dictionary) using catupgrd.sql from the 11.2.0.3.
Conversion to RAC will be done after completing the upgrade.  Essentially, this consists of adding one more Redo Log Thread and one more Undo tablespace.

  • Single-instance manual standby for a three-node RAC database

    Hi all,
    I am wondering how it is possible to create a manual standby database for a rac primary database.
    Oracle versione is standard edition 11.1.
    I have experience creating and managing manual standby for single-instance database; I am wondering if and how I can instruct the single-instance standby database to discover and apply the three redo threads that I will copy from the primary site to the standby site.
    Should I use rman to catalog all the archived log on the standby site ?
    Should I configure many LOG_ARCHIVE_DEST_n parameters to point to many different path, one for each primary instance (i.e. one for each redo thread), and let rman automagically discover all the archived logs ?
    Should I configure only LOG_ARCHIVE_DEST_1 , put archivelogs from all threads in the same folder, and let rman automagically discover all the archived logs ?
    Thanks for every answer!

    Hi,
    indeed i catalog all transfered archive logs in front of the recover process.
    During the tests i believe (iirc) i was unable to recover from transfered archivelogs without catalog them first. But this statement is out of my mind, i am not 100% sure for this, sorry.
    Some more details.
    Because it is a standard edition, i have to use on the RAC side ASM. So our normal scripts to transfer archivelogs from primary to standby are obsolete.
    So i decided to put the whole standby thing into the database. Now the primary database uses external scheduler jobs to do the work. The standby side is not using ASM, so there is no need to handle the logs in any special way.
    The steps are:
    1. Get SCN from primary and standby
    2. Transfer the logs for the gap from ASM to "normal" filesystem.
    3. Transfer (and compress, if not in LAN) to standby archive dest
    4. Catalog on standby side
    5. Recover on standby side
    6. Delete on normal filesystem (on both sides, but on standby with a delay of 2 days just to be sure)
    The steps on the standby side are both using the primary scn from step 1 as a parameter to avoid error messages during the catalog or recover call.

  • Multiple Single Instance DB Conversion to Cluster Database RAC

    Hi,
    Good Day.
    we are in planning phase to perform an activity, in which 8 existing (Single Instance) and 1 new database will be consolidated in ONE Oracle RAC Cluster database.
    Kindly share your ideas, to perform the consolidation smoothly with minimal downtime.
    can any one share the cons/pros, what if we create MULTIPLE RAC cluster databases instead of one cluster database?
    Thank You.
    Regards,

    The cons are pretty much the same as running multiple instances on a single server: Tuning will be much harder because you will have to look for bottleneck and depletion of common resources (CPU, RAM, IO) across all your instances instead of one (where you have lots of nice and integrated features). There is the potential for contention between resources and since each instance/database has its own SGA (and they are not shared) you will potentially waste a lot of ram for stuff that is redundant between the instances.
    But if you still think this is something you want to do, you should take a look at the 'server pool' feature. It will give you some more control over how your databases/instances should be ditributed across your rac (there is propably no need for all databases to be running on all servers at the same time)

  • Single Instance 10.2.0.1 Database using 10.2.0.4 ASM

    Hi,
    I have ASM running from one ORACLE_HOME1 which is upgraded to 10.2.0.4 version.
    I want to install new 10.2.0.1 database in another ORACLE_HOME2 which uses ASM storage from ORACLE_HOME1.
    Is this supported? Is it possible to place 10.2.0.1 DB on 10.2.0.4 ASM storage while installing?
    Thanks,

    Hi,
    Yes i think its will support.
    May i know is there any specific reason that you want to install new oracle_home(10.2.0.1)

  • CloudControl 12c: when adding cluster-database single instances are missing

    Hello ,
    I'e have installed the agent 12c on every single host of our RAC. When adding a database to CloudControl 12c just the RAC-instance gets discovered - but not the single database instances on each host.
    Due to this when clicking targets -> databases I just see the cluster-database - but not every single instance of the database.
    Compared to another RAC database this is totally different behaviour.
    Any help will be appreciated

    Hello ,
    maybe I should try to explain the issue a little bit clearer...
    We have one RAC database called PROD02. When clicking "targets -> databases" I see the following:
    PROD02 of type Cluster Database
    PROD021 of type Database Instance
    PROD022 of type Database Instance
    That's the way it shoudl be - that's the way I expected it...
    For the newly cofgured RAC database, called PREP02, it looks different when clicking "targets -> databases"
    PREP02 of type Cluster Database
    The single instances don't show up. Of course I see the single instances when clicking on "PREP02" under the item "Instances".
    Now I wonder why these two RAC databases are differently displayed when clicking "targets -> databases". When trying to add the single instances (clicking "Add" under "targets -> databases") and selecting then either "only on the host <hostname>" or "on all hosts in the cluster" no single instances are found or displayed...

  • 10gR2 single instance to 11gR2 rac upgrade

    Can someone tell me some good approach for upgrading a single instance 10.2.0.2 database of approx size 2TB to 11.2.0.3 rac 2 node db on linux.

    Hi;
    1. You can upgrade your db to 11gr2 first than convert it to rac
    2. You can use RMAN and restore it to new 11gR2 server
    3. You can use expdp/impdp to new 11gR2 server

  • RMAN + restore rac on single instance...

    Hi all,
    Can I restore a backup or RAC Database on a single instance?
    For example: DB1 is a RAC Database 10.2
    I have a RMAN backup of DB1 on host A, copy all files to host B on same directory structure.
    Can I restore this backup ??
    If someone have any documentation or link, i apreciate too much.
    Thanks

    Yes, you can. Follow the scenario 'restore the database to a different host'. Be aware you'll need BOTH archive threads!!!

  • Need help to create a login for maintenance of a single database in a multiple databases, single instance environment

    Hi,
    We are in the process of consolidating several databases on a single instance of SQL Server 2012.
    Databases are developed by outside vendors; they have to be able to install and support their databases but they shouldn't be able to do any thing with the other databases.
    When I tried to migrate the first database, the vendor told me that on the former server he used the sa account in some batch.
    On a previous thread
    https://social.technet.microsoft.com/Forums/sqlserver/en-US/dc1f802f-d8de-4e2b-87e5-ccb289593fb7/security-for-multiple-applications-on-a-single-sql-server-2012-instance?forum=sqlsecurity
    it was suggested to me that I create a login for each vendor and that this login should map a user in their respective databases.
    To test, I simulated the process in a test database:
    1 - I create the login and I scripted the command:
    USE [master]
    GO
    /* For security reasons the login is created disabled and with a random password. */
    /****** Object:  Login [M02_Test]    Script Date: 2014-12-02 16:23:58 ******/
    CREATE LOGIN [M02_Test] WITH PASSWORD=N'ÈS^y¡¶=Å€"+y¤j|úªhÖféÎЕœEu
    c', DEFAULT_DATABASE=[M02], DEFAULT_LANGUAGE=[us_english], CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
    GO
    ALTER LOGIN [M02_Test] DISABLE
    GO
    2 - I create the user and scripted it
    USE [M02]
    GO
    /****** Object:  User [M02_Test]    Script Date: 2014-12-02 16:29:41 ******/
    CREATE USER [M02_Test] FOR LOGIN [M02_Test] WITH DEFAULT_SCHEMA=[dbo]
    GO
    Questions:
    What should we do with te scrambled password: is it saved as it was entered and should it be kept somewhere in a safe place?
    Would that do the job for the vendor who used sa before?
    Thanks for your advice

    I'm not sure why you would save the script. Why not create the login, in one way or another give the vendor the password. Keep the login disabled until needed.
    I don't recall exactly what we said last time, but it occurs to me that the application setup things on server level. Jobs is the prime thing that comes to mind, but there could be other things.
    Now, here is an important observation. As long as the vendor's application was alone on the server, that was OK, and it was OK to give the vendor sysadmin rights. In this situation this is less OK, and as we said, you should only give the vendor db_owner
    in the database.
    But the vendor will need to tell you what they do on server-level. They should know this - unless they sell their app as a "alone-on-a-server application". (And there are indeed such applications out there, even from Microsoft.) But there is a
    risk that they will bill you extra if you make their installation more difficult.
    Maybe you will have to give some vendors sysadmin for the installation, but in such case, you should ask them why they need it. If they don't, give them db_owner, and they will have to find out their hard way. (And you don't pay them for learning
    their own application.)

  • Converting single instance database(11gr2) supporting EBS 12.1.3 to 2 node RAC on RHEL.

    Hi We are in the process of converting single instance database(11gr2) supporting EBS 12.1.3 to 2 node RAC on RHEL. Which version of RHEL is better? if its 6.x then x?? The oracle document only says RHEL update 6.
    thanks in advance.

    Hi,
    Yes you can use any version but i recommend  you to use 6.2

  • How to restore a single instance database to RAC (10g) using RMAN ?

    Hi all,
    I have a single instance database configured using file system in a unique server, so now I need to restore this database using RMAN to a new RAC environment with two nodes and ASM also.
    Does anyone can help with this documentation or a link about any information about this restore using rman ?
    I tryied found on metalink but threres isn´t this specific case. Only how to convert single instance to 10g RAC, but without how to use with rman information.
    System: Windows 2003

    In essense you are really doing nothing more than restoring a backup on a new host. If you want a blow by blow detail of how to accomplish it take at http://www.oracledistilled.com/oracle-database/restore-database-to-another-host-using-rman
    In order to write the files to the ASM Disk groups you will use the SET NEWNAME FOR DATAFILE in your restore script. You will also need to create the ORACLE_BASE/admin/<DBSID> structure on all of node. Once you get the database completely restore you will need to edit the SPFILE to include the proper value for the CLUSTER* parameters and each the node specific parameters. Sorry that it is kind of higher level than what you are probably looking for but the link above and what I put here should get you were want to go.

  • Configuring multiple services in a single instance database

    Dear All,
    I would like to create multiple service names for a single instance oracle database (10.2.0.3 on IBM - AIX 6.1). I tried searching on the net, reading documentation, and also on the metalink but couldn't find anything relevant to single instance database.
    Say I have two users, userA and userB, for which I would like to use two services (ServA and ServB) to connect to the same single instance database.
    Any help in this direction is appreciated.

    It is very hard to believe you didn't find this in the documentation, and my suspicion is you didn't search for it at all.It is very hard to believe that you don't trust others and end up in suspicion. I wish you were sitting next to me while I was searching for the link/document.It is because the vast majority of doc questions are asked by people who don't read the docs at all.
    Now, I'm curious about your requirement. While it can be done, it is pretty unusual. That always leads me to want to step back from the technical question and ask What business problem is this solving?

  • 10.2.0.4 patch on single instance standby database

    Hi All,
    We have production database 10.2.0.3 running with RAC having 2 nodes on Solaris 10. We have patched this
    databases to 10.2.0.4 (both nodes) on production without any issue.
    We have a physical standby database (10.2.0.3) with 2 nodes on solaris 10. But we have stopped node2 sometime
    back and currently it's a single instance standby database. Whe nwe are trying to apply patch to standby dataabse
    it's showing both node during installation and installation fails when it tries to search for node2.
    What's the solution for this problem? Any document on how to patch the single instance standby database when
    production is running in RAC.

    I think you are basically saying that you have a 2 node RAC cluster with 1 node down (possibly permanently) and you want to just patch 1 of the nodes?
    It's not overly a surprise the installer is trying to patch the other node, when as far as your inventory is concerned you have a 2 node cluster.
    Have you tried running the installer with the -local option?
    This should just patch your local node. Obviously the dictionary changes will get applied via MRP from the primary db.

  • Creating a RAC standby database for a single instance database

    Dear All,
    I have a task of migrating a 500GB single instance database to a two-node RAC database with a little downtime at hand. My migration strategy is to:
    1) Create a RAC physical standby for the Single Instance database
    2) Switchover to RAC standby.
    Primary and Standby OS and DB configurations:
    OS: Windows Server EE 2003 (64-bit)
    DB: Oracle 10g Database Release 2 (10.2.0.4)
    Oracle 10g Clusterware Release 2 (10.2.0.4)
    To create a RAC standby, I will:
    a) Install Clusterware (10.2.0.1)
    b) Install Database (10.2.0.1)
    c) Patch both Clusterware and Database (10.2.0.4)
    d) Create ASM instance for both the nodes (+ASM1 & +ASM2)
    e) create standby controlfile on primary
    f) Move standby controlfile, RMAN backup of primary, pfile, listener.ora, tnsnames.ora, password file to standby host-1
    g) make necessary changes to the pfile on standby host-1 like cluster_database, instance_name, thread, ...
    h) mount standby database and restore backup
    Kindly validate my steps and if there already exists such a document then please do provide me with a link.

  • Do we require HBA card for single instance database.

    Hi All,
    I have doubt that we are going to implement a single instance with ASM.

    Please suggest.
    Thanks and Regards,

    The question is : do you want your user to be able ti use their application offline ?
    If yes, then you may provide them a local database and use a JDBC type4 driver. (The application is fetch directly from the server when first connected and then is able to lauch the applicaiton off-line) Such a network listen is allowed by the JNLP security model without any application sign !
    If no, then why not having a single database and some user debedant table that store the user specific data (as usual), and using a login dialog-bon (or an auto-logon mechanism) to restric identify and access your database thru some business logic via RMI or any ligh-webservice technology.
    Anyway you have plenty of solutions ..... it only depends of what are the exact needs.
