Anyone know why the spid value I see in oracle query does not show in Linux?
I have to kill the session using "kill -9 spid" because Oracle won't kill the session normally as I have used kill session and disconnect commands over 2 days ago and nothing dead.
The session only has a select statement I am killing. no rollbacks, no dml.
Environment Oracle 11gR2 RAC, Linux 6.7

spid 64506 does not exist in linux OS, anyone know why?

No Rows selection

FYI: This is a new question so I'm creating a new post. Previous post was a different question Session marked for kill for many days
