> What is best way to check max number of concurrent session reported in > a specific AWR snapshot. Hi, Sanjay, How about checking v$resource_limit for sessions' max_utilization? If the instance has been bounced, you can still find the number in dba_hist_resource_limit. Or similarly, v$license for sessions_highwater (plus number of background processes if you count them)? There's no dba_hist_* view for the latter. Yong Huang -- //www.freelists.org/webpage/oracle-l
