Symptoms

On a RAC environment only, with no load on the database, observed that the "COMMENT ON COLUMN ..." command, which sets a comment on a column of a view, is taking much longer than in previous versions.

TKPROF for the sql tracing shows that there is a 1 second wait "Wait for Table Lock" for every comment statement.

 

Changes

 Upgraded to 11.2.0.4.
