Hi > How about this one.. I have one long "SQL*Net message from client" at > the end that took 14 seconds which constituted 42% of the Statement > Flat Profile. You mean, why it's not recognized as [idle] event? I don't know. I've tried to copy-paste your snippet and orasrp recognized this 'SQL*Net message from client' as an [idle]. Probably, full trace file contains some data which leads orasrp to decide that it's not an idle event. Or maybe it's just a bug in orasrp. What version do you use (orasrp --version)? Or you mean, why in the first place you have 14 seconds of 'SQL*Net message from client' in your trace? In that case I agree with Mark's explanation. -- Egor http://oracledba.ru -- //www.freelists.org/webpage/oracle-l
