Is there a way to limit access by user to a RAC service name?
Currently there is no mechanism that I'm aware of to
prevent certain users from user a particular RAC service. For example if I have
2 service names, i.e. <DBNAME>_APP and <DBNAME>_USR where the _APP
service name is available on all 3 nodes, however the _USR is only available on
1 node because it's for adhoc users who we do not want to be able to run queries
which consume all the processing on all 3 nodes. Currently we can't prevent the
adhoc users from using the _APP if they really wanted to. This would be a higly
desirable feature for us
