    How Can I create a cluster of two instances running on the same server?

    983797
      Hello,
      I can't find how to create a cluster or even a failover rule for my two instances running on the same server ODSEE 11gR1.
      Could you please help?

      Thanks,

          Hello,
          Clustering (intended as Sun Cluster, Veritas Cluster, etc... ) IS NOT SUPPORTED since 7.0:

          http://docs.oracle.com/cd/E20295_01/pdf/821-1216.pdf [page 20]

          and, based on my own experience, is the WORST way of achieving high availability of an LDAP Directory Service and an almost GRANTED way to get replication issues in your topology (lock, split, re-init, etc...).

          Please use instead the 'application-level' clustering that you get out of the box with the Multi-Master Replication.

            Thank you Marco.
            The fact is that i am using a VM under RedHat on which someone tried to install Xserver but it didn't work, and i am not feeling like debugging... So I trried to do it using command lines.
            I found an answer on the two last documents...
            Still, I have a question:
            When I try dsconf show-repl-agmt-status o=MyDN localhost:30004 (I am using two instances using ports 30003 et 30004), I get that error saying that "show-repl-agmt-status" failed on "localhost:389"...

            Any idea?
            Thank you

              This is due to the fact that you did not specified the 'source port' which the command dsconf shall talk to, so it takes the default value which is 389.

              try the following:

              dsconf show-repl-agmt-status -p 30003 o=MyDN localhost:30004

              HTH,
