Hi

I have a question on rolling upgrades of 2 node RAC databases.

I understand while performing a rolling upgrade i need to stage the patch to a directory and just launch Opatch from that directory and Opatch would roll over the patch to the remote node and apply it there .

My question is what happens to the existing and new user connections as the database is not stopped what happens when the patch is being applied to node 1

a)Users are already connectted to node 1
b) new users connection who are attempting to connect to node 1


regards
Hrishy

    I dont understand very well the question, do you mean apply an one-off as
    hot patch online?

    Thanks

    If I understand you
    question correctly, these are the steps to follow for a rolling patch
    install:
    1. Stop the instance in
    node 1 and all other relevant processes (asm if running from the same
    home, listener, em...)
    2. Install the patch
    with the OPatch option -local
    3. Restart services
    from step 1
    3. Repeat for other
    nodes.

    All that is under the
    assumption that the patch can be installed in a rolling fashion.

    Hi Cheng

    I mean a patch that is certified as a rolling upgarde patch that needs to be applied on both the nodes.
