Top Activity: java.sql.SQLException: ORA-00942
When I try to access the "Top Activity" link from within Enterprise Manager (10g) I get the following error displayed at the top of the page:
java.sql.SQLException: ORA-00942: table or view does not exist
The activity graph is not displayed and data for the Top SQL and the Top Sessions is not available. This used to work although it would be months since I last tried to access this information and I do not know what may have changed. Is there, perhaps, a script in the \rdbms\admin folder that I can run to rebuild the missing objects, or does anyone have any ideas what may be missing?
