A Session Shutdown procedure executes just before the server session is shut down. A Session Shutdown procedure takes no parameters. You can specify the name of a PAS for OpenEdge Session Shutdown procedure using the OpenEdge Explorer or OpenEdge Management or by setting the sessionShutdownProc property in the PAS for OpenEdge properties file (openedge.properties).
Unlike the Session Startup procedure, the Session Shutdown procedure is run as a non-persistent procedure, and any errors propagated by the Shutdown procedure are simply ignored. The PAS for OpenEdge session terminates immediately after the Shutdown procedure executes.
