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
