    convert standby to RAC

    This is the scenario
    Primary stand alone 11.2 ( running on standalone virtual server)

    I have built 2 node oracle rac and need to move to a RAC database on new hardware with minimal down time.

    I want to create a physical standby and switch over to but how can I convert standby to RAC ? can it be done before the switchover? Or has to be done after switch over?

    you can use DBCA to convert standalone database to RAC. Below are the high level steps.

    1. Backup the original single-instance database. (create template using DBCA)
    2. Perform pre-installation steps.
    3. Setup the cluster.
    4. Validate the cluster.
    5. Copy the preconfigured database image (from step 1)
    6. Install the Oracle database software with RAC option.

    Try hard to get what you like OR you will be forced to like what you get.

    Thanks,
    i saw the step above in oracle doc but its unclear whether i can use that method for standby, i think thats only for stand alone system.

    i just found this link which seems to have the steps that i need to follow

    i wondered if its possible to convert into rac without using the convert to rac wizard? this wizard is part of provisioning pack and comes with a license :/
