Alter materialized view log command is hanging waiting on SMON

edited Jan 30, 2015 10:02AM in Database Administration (MOSC) 3 commentsAnswered

I am trying to run several commands that affect an MV Log and all of them seem to be hang waiting on a SMON

One command is ALTER MATERIALIZED VIEW LOG ONTABLE EXCLUDING NEW VALUES; the other command is purge_log. Both are blocked by SMON. How do I go about finding the root cause of it and fixing it?

Thank you

Howdy, Stranger!
