Not all SQL operations appear in longops.  I don't rely on it.  For
example, a query that is pulling data to the client won't appear in
v$session_longops as the op gets reset at every fetch (as would
last_call_et get reset to 0).

What about v$session_longops or gv$session_longops?

SERIAL# goes together with SID as the unique identifier (within the

You need to look at SEQ# to see if the Wait Event is changing.

Hello

In order to identify long running queries I have been using
last_call_et, if a session with a large last_call_et then it has not
changed query.

Is it more useful add serial#? Since serial# does not change in a long
running query neither?

Thank you

Alex
