Ram,
After you issue DML, but before you run statistics, you can run
dbms_stats.flush_database_monitoring_info to update the views.

Subject: dba_tab_mod view
List,
After seeing lots of global services enqueue deadlock errors in our rac, I was
looking up the trace files. I was able to see the sql; the trace files are huge
(in GBs) . The sql was simple and was updating one table only repeatedly. I
wanted to know how many updates had happened in the table, but the dba_tab_mod
view is empty for that table. The table was last analyzed last night. Does this
mean that the updates did not happen at all due the deadlock errors?
To my knowledge, the DTM view is emptied out after a stats collection. Is there
anything else that would cause the no rows selected for a table from that view.

Ram.
