unique attribute collision when using multiple oracledb resources with the same vhost value in RHEL 5 or 6

Solution Unverified - Updated -


  • rgmanager throws a unique attribute collision error when multiple oracledb resources are configured with the same vhost value.
  • I cannot start both oracledbs when they have the same vhost value.
  • We had set up a service for Oracle 10G and the service was working as expected, we needed to add a second database, so we create a second instance in the service. When we restart the service only the first instance starts, I can manually start the second instance, but can't get it to start with the cluster, or be monitored by the cluster. Both instances use the same oracle userid.
