Drop Materialized View Hangs.
Hi,
We have a set of 28 materialized views that gets refreshed every 6 hours. Recently this set failed to get refreshed. A DROP MATERIALIZED VIEW also hanged (Library Cache Lock) indefinitely.
I have no clue about fixing this issue. Please share with me your ideas.
P.S:
Database was restarted before doing this: No other session is accessing these MVs.
Thanks,
Aswin.
