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!

All of a sudden, we are experiencing 10x the number of archived logs switch

 

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

 

Thanks.
