Hey all, While I'm trying to debug some messes, I see that EM12c's Top Activity historical data shows at least one 30-minute time period from this morning where two of the Top Sessions have the same SID. Since I know the app generating these two sessions must do so serially -- one will finish and disconnect before the other starts -- could this really be the case? Can two different direct-connect (no pooling) sessions created within a "short" period of time have the same SID? Evidence is on 11.2.0.3, but I know I've also seen this on 10.1.0.5 (which is now thankfully gone!). TIA! Rich -- //www.freelists.org/webpage/oracle-l
