Oracle 12.1.3 Parallel Concurrent Processing Failover

972657 Newbie
Currently Being Moderated
I have installed / configured PCP on 12.1.3 Ebiz

When I stop the processes on the PRIMARY NODE, the processes on the secondary node stop also
I want the SECOND NODE to automatically take up the processing the the PRIMARY NODE was carrying out

Any ideas what I am doing wrong?

I have Primary / Secondary node defined at the Conc Manger level
I have it set for the Conflict Resolution manager also (how ever I only have CRM set for Primary node... do I need to set this for the secondary node also?)

My aim eventually is to LOAD BALANCE between the two nodes and then have the failover automatic

Anyone out there seen any blatant errors with what I have described?

Thanks

    This is an expected behavior when you stop the CM normally.

    Please see old thread for the PCP failover docs you need to refer to -- https://forums.oracle.com/forums/search.jspa?threadID=&q=PCP+AND+Failover&objID=c3&dateRange=all&userID=&numResults=15&rankBy=10001

    Thanks for your answers

    I am a little confused

    Say I lost my primary node (hardware crash for example)
    Is the expected behaviour to then lose the second node processes also?

    Is there any automatic failover capability?

    No. If you shutdown the CM using adcmctl.sh script, then it is an expected behavior for the processes on the second (other) nodes to go down.
    Is there any automatic failover capability?
    Yes, which is explained in the docs referenced in the link in my previous reply.

    Thanks,
    Hussein
