Oracle 9i Upgrade to 10g - Single Database instances to RAC

Hi,
We are considering migrating from single SAP database architecture into
an Oracle 10g RAC architecture. The question i have is:
Are multiple PHYSICAL databases supported in one Oracle 10g RAC environment? For example, Is it possible to install and operate multiple databases in one single ORACLE 10g Real Application Cluster such as one SAP R/3 database, one SAP EBP and one
SAP BW database co-exist in a single Oracle RAC environment?
Regards,
Chengappa Ballachanda

Hi Sairam,
Due to the size of our Production environments we have decided not to pursue the MCOD option.
Eg: Take a QA environment which consists of SRM and BW and we have multiple nodes with both installed on each node. Now if I were to go the MCOD option then these instances can connect to one large Oracle File System using different schema's. 
What I'm trying to establish is in that one RAC, is it possible to have the multiple database instances on each node (SRM, BW etc) connect to multiple Oracle File Systems ie SRM connect to its own OFS and BW to its own instead of the one large shared OFS?
Hope this makes sense! Easier if I could upload a diagram!
Regards,
Chengappa

  • How to deploy oracle forms + J2EE application in single OC4J instance

    We have ORACLE forms application, which is deployed in OC4J Instance in application server.
    There are some modules, which are developed in Java/J2EE, which are invoked from Oracle forms application. Currently this java application is
    deployed in separate OC4J instance.
    Could you please help us how to combine this forms +J2ee application in single ear file,
    And this ear file has to be deployed in one OC4J instance.

    Maybe have a look at :

  • Enterprise Manager 10g - change database instance.

    I have installed 10g and I have been using the enterprise manager database control web applet to manage my database. I now have the need to manage a second database, but I cannot get the new databse to show up on the login page; the console still displays the original database.
    I am using the following link to connect;
    http://<hostname>.<domain name>:5500/em
    I have tried changing the Oracle_SID and running emctl start dbconsole and emctl start agent but with no luck.
    Any advice for a newbie at this?
    Regards
    Stephen A Hollingdale

    When emctl does not start for me, the easiest way I have found to get EM working again is to drop and re-create the EM repository. I do not Make sure your ORACLE_SID is pointing to the correct instance (I use oraenv).
    Remove EM repository (you will need passwwords for sys, sysman and dbsnmp)-
    emca -deconfig dbcontrol db -repos drop
    Create EM repository-
    emca -config dbcontrol db -repos create
    When you start emctl, it will give you the "new" URL to EM.
    Hope this helps,
    Dan

  • Migrate single instance to rac

    Hi all
    Currently i have installation Oracle SE (10.2.0.1) i want migrate to rac 2 x Oracle SE (10.2.0.3) ?
    Can i use RMAN? or i must use exp/imp ? i have difrent version of oracle so i dont knew
    Thanks

    Hi,
    well there are two ways to do that.
    A) use the existing infrastructure and the database and adding additional nodes.
    B) setup up new SYSTEM/HARWARE RAC environment and move single database instance to RAC.
    which OS you are using.
    why dont you upgrade your ORACLE or you can make use to transpotable tablespce also.
    Regards
    MMU

  • Can i create more than one instance for single database?

    HI
    anybody can tell me how to create more than one instance for single database(without using RAC)?
    thanks
    Kalanidhi

    Anandji,
    I sometimes think differently. I also think like what this person is asking..(although I have installed and administering 5 different RAC databases)
    The main doubt of mine is that we create multiple instances accessing the same storage area.
    Anyway the controlfiles of all instances will have the same information except the instance_names and instance id's.
    Hence I always think , why can't it be possible to to create another instance in the same system and point it to a controlfile which is copied from the other instance.
    Why can't the same files be shared between the two instances in a same system ?
    I know I am thinking a little bit confusing...
    Anyway I need to test that also...

  • DB13 Job fail with error :Database instance is shut down

    Hi All,
    Recently we upgraded our Redhat Linux, Database from 9i to 10.2.0.4 and SAP Kernel 640 to patch 347.
    Now my system is working fine but in DB13 jobs I am getting error:
    Job started
    Step 001 started (program RSDBAJOB, variant &0000000000763, user ID SHMITTAL)

    it is looking to me that somewhere still Oracle path is mentioned as of 9i version.
    I checked environment variables, Default profile, initSID.sap but not find any issue, checked on google it says check tnsnames.ora, I checked that file but there is no such parameter for Oracle home.
    Please suggest to resolve the issue.

    Hi,
    allthough I am not quite sure, because 9i is sooo old and 10.2 is even near out of maintanance,
    Kernel 6.40 is linked against a version 9 client thus forcing sidadm to work with a 9i environment.
    brtools 6.40 working as orasid (environment 10g)
    and failing as sidadm (in the 6.40 plain kernel environment (oracle 9i))
    is perfectly normal as far as I remember.
    I think there was a section in the version 10 upg-guide whichg says to switch brtools to version 7.0, even if you use a 6.40 kernel exactly for this reason. This is, because version 7.0 brtools are hardlinked against the instantclient 10.
    So these work even as sidadm with an environment set to a version 9 client.
    I can not verify exactly, any more, cause all our 6.40 systems have recently gone to oracle version 11
    requireing the switch to the 6.40 EX2 kernel and brtools 7.20.
    Try brtools 7.00 on current patchlevel.

  • Capture streaming does not work after upgrade of the source database.

    Hello,
    We have a complex system with 2 X RAC databases 10.2.0.4 (source) and 2 X single databases (target) 11.2.0.2
    Streaming is running only from source to target.
    After upgrading RAC databases to 11.2.0.2 , streaming is working only from one RAC to one single database.
    First RAC streaming is flowing to first single database only, and second RAC to second single only.
    First source-target is streaming fine, second capture are aborted just after starting with following errors:

    When we rebuilded one of them, everything works fine, but other are too big for rebuilding.

    Oracle development is already working on it but we need faster solution.

    What exactly did you reinstall? I am experiencing the same problem.

  • How can i create a new database instance in oracle 10g express edition?

    hello everybody
    i'm a student
    i am developing a database application
    i'm using oracle 10g express edition
    to run my application i need to create another database instance
    but i didn't find any option for doing so in that product
    if there is pls tell me where it is?
    if not pls tell me how to manually create it?
    regards,
    Chaitanya

    yaa i'm sure about that .
    i want one more instance of database.Can you perhaps explain why? I have a fair share of production and development servers - and not a single one of them needs to run more than one database instance.
    So I'm interested in what requirement you are trying to satisfy by using two database instances on a single platform.
    Oh yeah - if you want to create a custom XE instance (different SID, different tablespace sizes, more/less PL/SQL stuff installed, hack standard), make a copy of your XE db creation script (in your XE's +$ORACLE_HOME/bin+ and called createdb.sh ) and modify that for your needs.
    PS. even with a different SID, only a single XE instance can be run at a time - you can however have 2 different ones defined and then use one at a time (e.g. testing international settings, init param differences, etc.)

  • Oracle Database upgrade from 10g R2 to 11g R2

    Dear Oracle Experts,
    Currently we I have three database on Oracle 10g(10.2.0.5) in same oracle home and want to upgrade only one database out of three.
    Can you please advise if I can upgrade only one database instance(out of three database, same oracle home) and my two other database will run on 10g ? and can you please share steps also for the same
    Best Regards
    Farookh

    Hi,
    As Harry pointed out already, it's definitely possible and a good idea actually. By installing a new Oracle home you can easily revert back to the 10g one if you need to. It keeps everything separate and makes it cleaner.
    I would recommend reading the Oracle docs. DK2010 has written them down here:
    upgrade the database version 10.2.0.1.0
    I made some notes on how to upgrade your database from 10g to 11g over on my site, they are the exact steps I used. It might help you to have a read through them but you should definitely read the Oracle docs and make sure everything you need for your environment is covered before upgrading. [url http://www.ora00600.com/wordpress/articles/oracle-10g-to-11g-upgrade-guide/]Here are my notes.
    Hope that helps,
    Rob

  • Oracle 10g/11g database use on UEK versus Red Hat kernel? How widely used?

    Greetings
    is there any official or semi-official information regarding how widely used is Oracle UEK to run Oracle 10g/11g database (RAC or single-node) versus running Oracle database on Red Hat Linux or on Oracle Linux with Red Hat kernel ?
    I am asking because at my customer site there is a perception that Red Hat (or Oracle Linux with Red Hat kernel) is much more widely used in production to run Oracle 10g/11g database and therefore it will provide better stability even if the performance may be somewhat reduced compared to Oracle UEK option.
    So I need some sort of approximate percentage numbers of how well is UEK used in Linux Oracle community to run Oracle 10g/11g databases.
    Many thanks.

    The problem with the world is that the intelligent people are full of doubts, while the stupid ones are full of confidence. Well, in my opinion, a higher market share does not reflect the quality or reliability of a product. Take MS Windows for example. Unfortunately, the reason for success is often not due to knowledge and experience, but rather due to fear and sheep effect or herd behavior.
    Perhaps you can use other arguments or questions to help you to make a decision, eg.:
    Oracle has a better understanding of what Oracle products require than Red Hat.
    Oracle takes full responsibility for the OS and Database, no finger pointing.
    Oracle tries to provide a better product than the RHEL kernel.
    The Oracle UEK kernel contains Oracle driver software, not available for RHEL 6 or later.
    Oracle updates are free of charge, RHEL requires a subscription.
    Oracle as a company is about 20 times bigger than Red Hat.
    There can be reasons that require the use of the original RHEL kernel, for instance if the vendor of a specific driver for your hardware demands it. But otherwise...
