It’s working fine here. We are joining dba_rollback_segs to gv$rollstat,
and when I try it I see results from more than one instance.
Turn on spool sql and see what the query is. If we are selecting from
gv$rollstat, then we are just showing what the database gives us and there is
not a problem in Toad. If we are selecting from v$rollstat, then Toad
doesn’t think it is connected to RAC. We use
dbms_utility.is_cluster_database to determine if we are connected to RAC or not.
