Purpose
The HALT command requests a normal halt of VTAM® without disrupting active LU-LU sessions. (See also the HALT CANCEL command and the HALT QUICK command.)
CS z/OS® upper layer protocol (ULP) service access points (SAPs) will also not be disrupted.
When normal HALT is issued for a VTAM, none of the sessions on that VTAM will be able to be recovered using the MNPS function.
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 normal HALT processing.
Operands
- CDLINK
- Specifies whether any active, leased, 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 command. Any CDLINK specifications on subsequent HALT commands are ignored.
- CDLINK=ACT
- Specifies that any active 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 those cross-domain links.
