Real application cluster

dear friends,
I am stuck in situation. I have 2 Dell Servers with linux os. oracle 10g database is installed on that 2 servers.
now i want to configure replacation for these to databases, for this is i preffered RAC.
i want to know... how to configure rac... and what are the requirements i have to take..
I would appreciate if anyone can send me the document followed to install RAC in my environment as i mentioned above.and also the hardware requirements of the server for installing RAC...
my email is [email protected]
Any help will be highly appreciated.
thanks in advance

RAC is not a simplistic 1-2-3 install process that anyone can list here for you to follow.
Read the manuals. (http://tahiti.oracle.com)
PS. And you have to have a license for running RAC. It ain't free.

    stop. BAAN and Oracle will have an "implementation guide" or best practices. There is also the Oracle MAA Maximum Availability Architecture. Go Read those first.

  • What is Oracle 10g Release 2 Real Application Cluster?

    Hello Guys,
    I have been working in Oracle database 9i for last 2 years. Just using the simple features of oracle. Now our data have grown and company wants to enhance the database version and also want to perform load balancing at oracle's end.
    Have heard a lot about Oracle RAC, but i am not sure what actually is oracle rac and its installation.
    What is the difference between Oracle 10g Release 2 Enterprise Installation and Oracle 10g Release 2 Real Application Cluster installation. Are these 2 different softwares available on different CDs or RAC is only a different way to install oracle 10g database in RAC mode.
    Please clerify and explain. Sorry this is a very beginner level question but i want to learn it and implement it.
    Regards,
    Imran Baig

    What is the difference between Oracle 10g Release 2
    Enterprise Installation and Oracle 10g Release 2 Real
    Application Cluster installation. Are these 2Enterprise Edition is the database management software provided byu Oracle.
    RAC is an extension to the Standard and Enterprise Edition to permit the same database to be managed from two or more computers. (Withe Enterprise Edition, it is an extra cost option. With Standard Edition, it is included in the price, since SE has other limitations.)
    Conceptually, RAC is simple - IF you understand the difference between Instance and Database. RAC = 1 database managed by many instances
    Physically, RAC requires a healthy investment in infrastructure - the infrastructure and the RAC software addresses the question: how do you get several computers able to read and write to the same disk and the same block without data corruption?
    If you are serious about RAC, take a course. If you are in the US, consider http://www.psoug.org as an 'Intro to RAC' course provider.

  • How to configure SAP 4.7 to Oracle 9i Real Application Cluster ?

    We are using SAP 4.7 running on Oracle 9i with HP-UNIX clustering.
    If we change our existing SAP 4.7 for Oracle 9i Real Application Cluster, is it very complicated ?
    Do we need to re-install SAP and Oracle ?

    Both 4.7 and Oracle 9 are already out of support.
    If you plan to use RAC then I'd first upgrade the application and the database and then implement RAC. You won't have support for your environment without additional costs.

  • Newbie question about Oracle Parallel Server and Real Application Cluster

    I am trying to find out what kind of storage system is supported by the 9i Real Applicaton cluster. I have looked at the 8i Oracle Parallel Server which requires raw partitions and therefore NAS (network attached storage) that provides an interface at the file level will not work. Does anyone know if the 9i Real Application cluster has a similar requirement for raw partitions? any suggestions of whether SAN or other technology will be suitable? pointers to more information is appreciated.

    Hi Derik,
    I know this is a really broad question. No, it happens all the time! Here is a similar issue:
    http://blog.tuningknife.com/2008/09/26/oracle-11g-performance-issue/
    +"In the end, nothing I tried could dissuade 11g from emitting the “PARSING IN CURSOR #d+” message for each insert statement. I filed a service request with Oracle Support on this issue and they ultimately referred the issue to development as a bug. Note that Support couldn’t reproduce the slowness I was seeing, but their trace files did reflect the parsing messages I observed."+
    I would:
    1 - Start by examining historical SQL execution plans (stats$sql_plan or dba_hist_sql_plan). Try to isolate the exact nature of the decreased performance.
    Are different indexes being used? Are you geting more full-table scans?
    2 - Migrate-in your old 10g CBO statistics
    3 - Confirm that all init.ora parms are identical
    4 - Drill into each SQL with a different execution plan . . .
    Raid 5 Don't believe that crap that all RAID-5 is evil. . . .
    http://www.dba-oracle.com/t_raid5_acceptable_oracle.htm
    But at the same time, consider using the Oracle standard, RAID-10 . . .
    Hope this helps . . .

  • Help! Real Application Cluster!

    Is there anyone who setup real application cluster on linux machine.
    I wanna setup RAC( two instance on one machine ).
    I don't have shared storage. Can I setup with extra ide harddisk?
    Is SID same each instance on one machine?
    Give me your information, please!
    Thanks for your reading.
    have nice day!

    Hi
    Cluster means MORE than one machine, so you need al least 2 machines (better 3 or more)
    basic:
    node1---------node2--------- OUTSIDE WORLD
    oracle oracle
    private IP1 private IP2
    Public IP for world
    Better:
    node1 ---node2----entry point---OUTSIDE WORLD
    oracle oracle Public IP
    prvtIP1 prvIP2 cluster control
    node 1... node N MUST share a space, so if you don't have an array you MUST find a network file system to share between nodes.
    NFS/SAMBA don't work, because Oracle needs to mount this system as RAW, I'm trying it with LVM but I don't know if it will work.
    So first create a cluster, then mount a shared space as raw. Then try Oracle.
    A10!

  • Hardware Architecture of Real Application Cluster (RAC)

    I'll implement Oracle 9i with Real Application Cluster (RAC). I now have two Sun SF280R servers.
    Can I use ONE common storage to build RAC?
    SF280R - Storage - SF280R
    OR is it necessary to have TWO storages?
    SF280R SF280R
    |..........\/..........|
    StorageStorage
    Thanks

    The whole idea behind RAC is that there is shared storage for 2 or more database instances. If one instance goes down, the other(s) seemlessly take over. RAC provides insurance against instance failures. Stand by databases (also known as data guard) provide insurance against database (the actual data files) failure.

    thank a lot for help!

    Hi,
    HW sizing depends on lot of information like the Size of the Database, Average load on the Database, Number of DB users, what application is using the database... could you please let us know all these information and oracle license depends on the number of CPU you on the server. Kindly let us know the OS on which you want to run the oracle RAC.

  • Oracle real application cluster test case

    Hello everyone! I have just finished implemented oracle real application for customer. Now I need to do UAT for them with cases. Some of the cases I am not sure whether it can make the cluster fail, or need to repair, or unrecoverable. I need to tell them what is happening if sth go wrong as the following cases:
    case 1. connection from database server to storage is down in one node, or all node in the cluster.
    case 2. private connection down
    case 3. public network down in node node or all nodes in the cluster.
    Please, help address the status and behavior of oracle rac, or suggest me some useful document regarding this cases.
    I'll appreciate your help.

  • Configure JDBC to Real Application Cluster (RAC)

    I'm searching for some documentation on how to setup a JDBC connection to RAC. Can anyone point me in the right direction? Specifically, we're using Weblogic 7 on a Sun Solaris box and using RAC for load balancing and failover protection. I need to know which type of driver to use (Type 2 or 4) and the specific connection information such as naming (or IP) in order to connect to the cluster.
    Thanks.

    Hi buddy,
    Let's clarify some points:
    Redhat Cluster Suite can create n-node server clusters, load balances incoming IP network requests and supports up to 16 nodes. So, do I need to configure RAC if I'm going to use Redhat Custer Suite?RAC- Real applications clusters, a clustered database so that many instances can accessing only one database, many features available like cache fusion.
    CRS- Cluster Solution from Oracle needed to run RAC databases with or without a vendor cluster solution.
    with the information above I'd say:
    1) If You want to use a cold fail over cluster, You can use a vendor cluster solution or just CRS.
    2) If You want to use RAC databases, You must use CRS, with or without a vendor cluster solution. ( since release 10G no more needed to use a vendor cluster solution)
    Hope it helps,

  • Real application cluster installation

    I'm doing an install of RAC on Linux AS 2.1 using OCFS. I am following the
    directions from the 'Step by Step RAC Linux Installation'. I got the cluster
    manager to install correctly and started cluster manager on both nodes.
    However, when I run the installer again, the 2nd node doesn't show up on the
    "Cluster Node Selection Screen". I'm think both nodes should be showed on the
    selection screen. What is wrong???

    There is a new book on Oracle9i RAC and it discusses in detail all issues with Oracle Real Application Clusters instalation problems:
    Here is a link to it:
