How long is Oracle dead session in V$ session?
But it remains in v$session for 10 days, although an attached process is absent in v$processes. I’ve also checked all Linux processes related to Oracle and found no zombies: all present processes are consistent to alive sessions. This happens not for all the killed sessions.
