Hi Experts..

I have 11.1 Cluster with 10.2 Db with out ASM,

My Plan is I want to upgrade the cluster to 11.2 and Convert DB to ASM. so the plan would be below

1.Upgrade 11.1 to 11.2 Grid (Rolling)
2.Upgrade DB to 11.2
3.Make sure db is good after Upgrade and check application is fine
4.Configure Devices For ASM and create ASM instance and DIskgroup using ASMCA
5.Convert Existing Db from CFS to ASM

So My question here is,

Can we Configure ASM after we upgraded Grid without ASM Option, using ASMCA?

Can we move Cluster Configration Files to ASM after we upgraded?

    Hi,

    I think yes, you must create a ASM disk group with redundancy 5 way for OCR and VOTE Disk, and you can move to OCR and VOTE into ASM Disk group.

    Check : http://docs.oracle.com/cd/E11882_01/rac.112/e16794/votocr.htm
    and

    Thanks Mahir,

    But My other question is My current system is Not Using ASM, I want to Upgrade Cluster from 11.1 to 11.2, and check all is good

    then i want to create ASM instance and Diskgroup using ASMCA,

    If i Create ASM instance and Diskgroup after i upgraded Cluster, How will my DB and cluster act?

    Can i do in this way?

    Thanks

    As you know, after 11g R2 Grid Infrastructure is togather ASM and Clusterware, GI = ASM + Clusterware
    When you upgrade, you must install GI, after installation GI created ASM instance.
