Clearing MSC link affinity in IMS Connect

Normally, IMS Connect automatically clears MSC TCP/IP link affinity when all of the MSC logical links on a physical link are terminated normally in IMS. If the affinity persists in IMS Connect, you can clear the affinity by stopping and restarting the physical link path in IMS Connect.

To clear a persistent affinity of an MSC physical link to an IMS system in IMS Connect:
If for some reason the link affinity does not clear in IMS Connect, you can stop the physical link path in IMS Connect by issuing any one of the following IMS Connect commands:
  • The IMS type-2 format command UPDATE IMSCON TYPE(MSC) NAME(lclPlkid) STOP(COMM)
  • The WTOR format command STOPMSC lclPlkid
  • The z/OS® MODIFY format command UPDATE MSC NAME(lclPlkid) STOP(COMM)
Before the link can be used again, you must restart the link in IMS Connect by issuing one of the following commands:
  • The IMS type-2 format command UPDATE IMSCON TYPE(MSC) NAME(lclPlkid) START(COMM)
  • The WTOR format command STARTMSC lclPlkid
  • The z/OS MODIFY format command UPDATE MSC NAME(lclPlkid) START(COMM)
