session dentification

Hi,
I want to mark records with an unique "identifier" which contains userid and session, who created/last modified the record. I need to know from "outside" (other sessions), whether the modifying session is still alive.

The sys_guid() function provides a unique identifier, but how can I find out the sessions state from outside?

Is there another possibility?

TIA
