DBA_HIST_SQLSTAT contents

Posted on 10-May-202310-May-2023 By Admin No Comments on DBA_HIST_SQLSTAT contents

Query DBA_HIST_WR_CONTROL to see the interval, retention and the TOPNSQL setting.  For TOPNSQL a setting of DEFAULT translates to:

30 where statistics_level is typical

100 where statistics_level is all

Simply because this one SQL appears to consume 7% of the load it may not be in the top SQLs in these categories:

Elapsed Time

CPU Time

Parse Calls

Shareable Memory

Version Count

If the SQL doesn’t make the ‘cut’ it isn’t saved and statistics aren’t collected.
