Stopping IMS Connect communication with an IMSplex when MSC TCP/IP links are supported
You can stop communications between a local IMS Connect instance and a local IMSplex by issuing an IMS Connect command, such as the WTOR format command STOPIP.
Stopping IMSplex communications breaks all MSC TCP/IP physical links that are supported by the local IMS Connect in the local IMSplex.
When
a STOPIP or similar command is issued, the following actions occur
for MSC TCP/IP links:
- The local IMS Connect disconnects the parallel send and receive socket that support the physical link and sends a shutdown directive to MSC in the local IMS system.
- When MSC receives the shutdown directive, MSC cleans up the physical link and issues message DFS3176E.
- IMS Connect changes the status of the MSC TCP/IP physical link to DISCONNECTED.
To stop communication between a local IMS Connect instance and a local IMSplex from the local IMS Connect instance issue any one of the following IMS Connect commands:
- In the IMS type-2 format, UPDATE IMSCON TYPE(IMSPLEX) NAME(imsplex_name) STOP(COMM)
- In the WTOR format, STOPIP imsplex_id
- In the z/OS® MODIFY format, UPDATE IMSPLEX NAME (imsplex_name) STOP(COMM)
