RE: 10g - System Statistics - Quick Q

Joe, that refers to table stats rather than system stats (CPU speed etc)
Chris, I thought that dbms_stats.get_stats_history_availability held the date 
when system stats were gathered but a quick test proves not

SQL>SELECT dbms_stats.get_stats_history_availability FROM dual;

GET_STATS_HISTORY_AVAILABILITY
---------------------------------------------------------------------------
24-DEC-08 00.28.08.278050000 +00:00

SQL>execute dbms_stats.gather_system_stats('START');

PL/SQL procedure successfully completed.

SQL>execute dbms_stats.gather_system_stats('STOP');

PL/SQL procedure successfully completed.

SQL>SELECT dbms_stats.get_stats_history_availability FROM dual;

GET_STATS_HISTORY_AVAILABILITY
---------------------------------------------------------------------------
24-DEC-08 00.28.08.278050000 +00:00

In fact I now have 2 questions to answer, yours and what happened on 24th Dec. 
I assume from the time that is the standard gather_optimiser_stats job that has 
not run since then, more investigation methinks

Not sure if this will help but I believe there is a last_analyzed column
in dba_tables that might be of use.  Can't check right now but I think
that's the name.

Anyone know how to determine when system statistics were gathered?  IE,
the last time?
