Further discovery in toad for 12c RAC database when I try to generate script of a table in toad, for 12c RAC it took 3.4 second and it only take 52 msec in the redHat. Why is that? But when I cut and paste (select name from sys.user_snapshots where 1=1) into toad editor and run in 12c RAC and 10g RedHat, they both take less than a second. It is really weird. Can you tell me what is toad doing at the background? ============================================= 12c RAC session, is taking approximately 3.4 seconds ============================================= SESSION: SDE@TIMSACPT Timestamp: 09:45:41.456 Select name from sys.user_snapshots where 1=1 ---------------------------------- SESSION: SDE@TIMSACPT Timestamp: 09:45:44.948 ============================================ 10g RedHat session, is taking approximately 52 msec ============================================= SESSION: SDE@TIMSACPT.WORLD Timestamp: 09:55:20.440 Select name from sys.user_snapshots where 1=1 ---------------------------------- SESSION: SDE@TIMSACPT.WORLD Timestamp: 09:55:20.492
