Subject: Re: archived log switch

Michael,

The only session-level redo information is the real-time information in V$SESSTAT; I don't think there is anything usable in AWR. Query V$SESSTAT (via a join from V$STATNAME for the statistic name via the column STATISTIC#) for a statistic like "redo size" in order to identify a session (or sessions) generating a lot of redo, the join back to V$SESSION and figure out to whom that session (or those sessions) belongs, what it is executing, etc.

Good luck!

Does anyone have ideas on how to identify what is causing so many archived logs?

Thanks.
