Hi Everyone,
AWR has wealth of performance related information. Apparently in Exadata x2-2 with Database Bundle Patch 12 and + broken for some reason.
Scheduled WR snapshots never completes. Manual snapshots just hangs.
We had Database Bundle patch 12 and we have noticed the issue,. Our Latest Exadata x2-2 Quarter Racks having database bundle patch 14 - with same AWR snapshot issues.
After gathering fixed object statistics, issue has gone away. :-)
SQL> EXEC dbms_workload_repository.create_snapshot;
....just hangs..
SQL> exec DBMS_STATS.GATHER_FIXED_OBJECTS_STATS;
PL/SQL procedure successfully completed.
SQL>
SQL> EXEC dbms_workload_repository.create_snapshot;
PL/SQL procedure successfully completed.
SQL>
Hope someone will benefit out there.

This was with 11.2.0.2 DB.
If that still doesn't work, try collecting
exec DBMS_STATS.GATHER_DICTIONARY_STATS ; then it will start working.
