Mark,
If you're on 10.2 have you thought of querying V$SQLSTAT? AFAIK it has a longer retention period.

Hi Listers, I havent posted for a long time so here goes! I've never really understood why the statement I am looking for never seems to exist in the various xx_SQLTEXT tables. For example: while investigating a capture error: Tue Nov 18 02:36:56 2008 C001: large txn detected (44115 LCRs), xid: 0x02a9.05c.00000414 I located the sql_id from v$session_longops, which confirmed that the session rolled back _"Transaction Rollback: xid:0x02a9.05c.00000414 : 4780 out of 4780 Blocks done"__ a_nd it has a sql_id of "86gsuryqg5hh5". However I cannot locate this statement in v$sqltext, or wrh$_sqltext. I assume it aged out of v$sqltext (even though I started querying within minutes of the error), and didn't exceed thresholds enough to be logged to wrh$_sqltext. Yet capture though the statement evil enough to record it in the alert log. Logminer is the only option, and all of the hassle that it entails. Should I be looking elsewhere to find the statement? Has anyone modified thresholds (successfully!) for WRH to try to log more SQL and make it a useful feature; given its overhead? Thanks Mark
