BUG 22216663
When adding a database resource to a cluster group, if the group contains more than one network name resource, Oracle Fail Safe Manager will display a selection list that allows you to select which network names to use for the group's Oracle TNS net listener address list. However, the list was not sent to the Fail Safe server which would result in the server defaulting to all the network names for the group.
This problem has been resolved. The Oracle Fail Safe Manager now sends the list of selected network names to the server.
The workaround is to manually update the group listener's description in the listener.ora file to only include the addresses of the desired network names. The listener.ora file must be updated on all cluster nodes. The changes will not take effect until the listener is restarted.
