Oracle RAC 11gR2 on Windows - Disk Storage Newbie question

Hi all
I have been reading through the Grid install guide in an effort to understand how to set up a RAC solution. I am new to Oracle so a lot of these concepts I am trying to understand but from what I am reading a typical install would be to have my cluster software installed on a particular shared storage type of either OCFS or ASM. These storage types then sit on top of a redundant option such as RAID, or logical volumes across disks or a kind of mirroring (SAME).
I know what I have said is probably a rough attempt at understanding this but what I would like is if anyone has any diagrams that lay this out for me to aid my understanding that would be great.
I am kind of at a stage where I am thinking about creating a RAC installation on some VMWare and want to know how best to configure the initial disks, and whether to add them to a RAID or carve them into partitions.
Hope I have made sense.
Thanks

Hi;
Please change thread status to answered here, it pretend to lose time of other forums user while they are searching open question which is not answered,thanks for understanding

  • Oracle RAC 11g on Windows 2008 64 bit - blue screen error on both nodes

    Hi Everyone,
    I installed Oracle RAC 11g on Windows 2008 64 bit, The installation was successfull and crs_state -t shows all services in two nodes are online.
    When executed a select query with 100 sessions( For performance evaluation using Transaction generator ) ,the machine got crashed and blue screen is appeared on two nodes. I restrated the machines and and starts the same evaluation ,bt the same bug is repeating.
    Can anyone suggest a solution to solve this issue? Is our hardware is not sufficient ? Shall we need to perform any
    specific settings in Oracle RAC setup for performance evaluations?
    Is our settings for load balancing is not enough? ( We added "Load Balancing= On" on tnsnames.ora on client for load
    balancing)
    The following machine configuration is used for Oracle RAC setup
    Intel Core 2 Duo 2.66 GHz,

    Oracle RAC , Clusterware 11g R2 64 Bit.i guess you have installed/configured RAC using VMware. i guess, the problem is with your RAM size. how much disk space and RAM size you have allocated for each machine?
    which documentation you have followed?

  • Domain migration of Oracle RAC nodes on windows 2008

    Hello masters,
    We are planning to migrate servers from old domain to a new domain due to company name change. That is, our DB servers named like db-node-x.old-domain.com will be migrated to db-node-x.new-domain.com. The servers are all on Windows 2008 R2 and Oracle RAC 11g2. As dba, i have no idea about what will happen to DBs. Please let me know any possible solutions?
    Thanks in advance.

  • Using ZFS for Oracle RAC 11gR2 binaries

    Hi,
    We have following scenario,
    Two Node Cluster: Oracle RAC 11Gr2 with Clusterware on Solaris 10
    We want to keep Oracle & Clusterware binaries on ZFS mirror file system on each node locally and for Data files, FRA, Voting disks & OCR on shared SAN using ASM.
    My question, is the above scenario certified by Oracle or can we keep Oracle binaries on ZFS...?
    Will appreciate your input.
    Thanks

    Well my confusion started after reading this doc on oracle support:
    Certification of Zeta File System (Zfs) On Solaris 10 for Oracle RDBMS [ID 403202.1]
    "Oracle database 10gR2 (10.2.0.3 and higher patches), 11gR1 (11.1.0.6 and higher patches) and 11gR2 (11.2.0.1 and higher patches) are certified with Solaris 10 ZFS on Sparc 64-bit and Solaris x84-64. See Solaris ZFS_Best_Practices_Guide. This is for single instance ONLY. ZFS is currently not applicable to RAC and not Certified to use it as a shared filesystem."

  • Is OCFS2 certified with oracle RAC 11gR2 ?

    Hi,
    Is OCFS2 certified with oracle RAC 11gR2 ?
    Thanks..

    ocfs2 is certified for oracle 11gr2 but oracle recommends using asm. please see this for more information http://download.oracle.com/docs/cd/E11882_01/install.112/e10812/storage.htm#CWLIN262

  • ASM pfile lost in Oracle RAC 11gr2

    Hello Gurus,
    I am new to Oracle RAC 11gr2 and facing some issues. our spfile/pfile for asm instance is lost and I am not able to startup the asm instance.
    Environment is as below:

    Hi,
    Do we need to Set variable ORACLE_HOME properly (Grid Home) while starting RDBMS instance?
    e.g ORACLE_HOME=/u01/app/11.2.0/grid*I recommend you set ORACLE_HOME properly for each Oracle Installation when you use SQLPLUS.
    i.e: cat /etc/oratab
    orcl:/u01/app/oracle/product/11.2.0/db_1
    db10g:/u01/app/oracle/product/10.2.0/db_1
    +ASM1:/u01/app/11.2.0/gridAlso you can startup/shutdown our database with SQLPLUS using ORACLE NET*, but it must be configured properly.
    My recommendation <s>is always</s> use SRVCTL and CRSCTL to manage to your environment. Track all the process of initialization processes through the logs using ADRCI utility (only 11.1 or later).
    When use SRVCTL or CRSCTL to manage I recomend you use (GRID HOME).
    SQL> alter database open;
    alter database open

    SQL>I give to you three options:
    1° - Add more asmdisk on Diskgroup +FRA
    2° - Make backup of all archivelog using RMAN and option delete input (i.e backup archivelog delete all input;)
    3° - If this database is for TEST ONLY and you not need backup or recovery of then you can delete all archivelog using RMAN (i.e delete archivelog all;)
    I recommend you create routine of backups of the database and archivelog to prevent this area becomes exhausted.
    If you need the database in archivelog but it is only to test then create routine to delete archivelogs periodically.
    If you dont need the database in archivelog, then just disable it.

  • Oracle rac 11gr2 + sga

    Hi all,
    I have a 2 nodes rac 11GR2 on linux redhat with 12Go RAM each one.
    Since 15 days, a dba add more memory on each node (+ 24Go RAM) and modify SGA like :
    On each node :
    create a pfile from spfile, modify memory_max_target on pfile (from 7Go to 8Go), and restart each instance from this pfile.
    Now, the problem are :
    Each node consume 36Go of 36Go RAM,
    The parameter spfile is empty (show parameter spfile).
    Do you an idea why all RAM is consumed on each node ?
    Thanks.

    Problem 1: Why is that a problem? How did you establish 36 Gb is used. The Unix tools are notoriously for providing incorrect information as the SGA is accounted for in every process.
    Problem 2: Evidently the "DBA' used an incorrect procedure to change these parameters, and didn't convert the pfile to spfile again, and started using the 'startup pfile' command.
    The action plan for this twofold
    - educate the "DBA' or don't hire him anymore
    - use the create spfile from pfile command, and restart the database.

  • Cluster_resource not starting in oracle RAC 11gR2 after adding

    I am using a RAC of 2 nodes (rac1,rac2) on windows 2008 Server R2 with Oracle 11gr2 grid installed.

    CRS-2674: Start of 'check' on 'rac2' failed

    Please help me in solving this problem.

    Hi FZheng ,
    Thanks for your reply.
    agent.exe is a application containing start/stop/clean/check cases.Its a simple application through which we want to check cluster resource addition.
    Yes Grid user has privileges to rum agent.exe.
    One thing more I want to add,this problem is only coming for ORACLE 11gR2.
    All other versions (11gR1,10g) its working fine.
    If we check crsd.log in %GRID_HOME%/log/crsd directory ..the logs are as follows:
    *[ AGFW][3616] Starting the agent: C:\app\11.2.0\grid\bin\scriptagent.exe with user id: administrator and incarnation:9*
    *[ AGFW][3616]Created alert : (:CRSAGF00123:) : Failed to start the agent process: C:\app\11.2.0\grid\bin\scriptagent.exe Category: -2 Operation: OpenService Loc: getusrtok2 OS error: 1060 Other : OpenService Failed*
    *[ AGFW][3616]Created alert : (:CRSAGF00126:) : Agent start failed*
    I guess the problem is with scriptagent.exe which is used to start 3rd party cluster resources.
    Please comment.
