v$session_event vs v$session_wait !
I am having trouble understanding the difference between v$session_wait and v$session_event. I read the oracle reference documentation and still don't get it.
For example , sometimes I got the "enq: TX - row lock contention" related wait event from "v$session_event" view but at that moment there is no wait event under the "v$session_wait" view . So for any wait event which view I need to consider and why ?
Anybody can explain this to me? Thanks.
