Purpose

You can use the HALT QUICK command to halt VTAM® more quickly than with a normal HALT command. However, HALT QUICK disrupts LU-LU sessions. In a session using multiple resources, you must wait for any deactivation requests to complete before you issue this command. Otherwise, you will have to issue the VARY INACT command to force deactivation of the session. (See the TYPE operand of the VARY INACT command for more information about forced deactivation.)

VTAM will initiate deactivation of Communications Server z/OS® upper layer protocol (ULP) service access points (SAPs).

This command causes sessions to terminate. Multinode persistent sessions are not recoverable.

If a VTAM dump, load, or restart subtask is active when a HALT QUICK command is issued, the subtask is detached and a system completion code of X'13E' or X'33E' results. VTAM termination continues.

Rule: You must reply to any VTAM operator messages that are outstanding before HALT QUICK can complete.

If VTAM was defined as a network node or interchange node and a checkpoint data set is available, VTAM takes checkpoints of the directory database and the topology database during HALT QUICK processing.

Operands

CDLINK

Specifies whether any active cross-domain SDLC links between NCPs are to remain active after the NCPs have been deactivated.

This operand is effective only on the first HALT QUICK command. Any CDLINK specifications on subsequent HALT QUICK commands are ignored.

CDLINK=ACT: Specifies that any active, leased, cross-domain SDLC links are to remain active after the NCP major nodes are deactivated, so that information being routed through the NCPs can continue to be so routed. That is, any cross-domain sessions that use the NCPs as transit nodes can continue.
CDLINK=INACT: Specifies that cross-domain SDLC links are to be deactivated, along with the rest of the domain. This disrupts any sessions through these cross-domain links.
