Alright I ran this command: exec dbms_stats.gather_system_stats(interval=>90,stattab=>'SYSSTATS',statid=>'DEC12'); It returned in a minute, so I assume that it runs in the background now. I've noticed two rows in my SYSSTATS table, but the column names are a bit unintuitive. Is there a HOWTO on interpreting that data? Don.
