Controls whether or not a back-end session ACB is closed if the ACB has no active sessions.
This parameter is applicable to the SYSTEM control statement (see SYSTEM statement).
The CLOSEACBINACT parameter with the Yes or ON option causes the closure of a back end session ACB if the ACB has no active sessions. The default behavior is for all ACBs to remain open until IBM Session Manager terminates or the ACB fails, which avoids the need to re-open the ACB when it is next used. Alternatively, specifying CLOSEACBINACT=Yes may decrease the time taken to terminate IBM Session Manager as inactive ACBs will not need to be closed.
