Disappear Oracle session
Hi guys, I have so problem, client program which run heavy queries (executes long time 30-45 min) after some time disappeares from sessions in the Oracle database, it seems that Oracle has killed session but no any mesages in alert log and program still running. I run so query in Toad as example, session has disappeared but Toad shows that it query is still running. Database version 11.2.0.1, Linux 64 platform. Maybe somebody faced with so problem.
