Cleaning up an ISC parallel session in IMS Connect

If an ISC parallel session has terminated in IMS, but the IMS Connect resources associated with the parallel session did not clean up automatically, you can clean up the resources by using the IMS type-2 command UPDATE IMSCON TYPE(ISCUSER).

Recommendation: Under normal circumstances, use the IMS /QUIESCE NODE command to terminate ISC parallel sessions. Stop an ISC parallel session in IMS Connect only if the IMS Connect resources that are associated with the ISC parallel session fail to clean up correctly after the session is terminated in IMS.
When you clean up ISC parallel sessions in a local IMS Connect instance by using the UPDATE IMSCON TYPE(ISCUSER) command, IMS Connect takes the following actions:
  • Stops any communication on the ISC parallel session
  • Notifies the local IMS that communication has stopped on the parallel session
  • Deletes the control blocks associated with the parallel session and frees the associated storage
  • Issues message HWSG4010I

Procedure

To stop an ISC parallel session and clean up its associated resources in IMS Connect, issue the UPDATE IMSCON TYPE(ISCUSER) command.
IMS Connect issues message HWSG4010I after the link is stopped.
