Stopping an MSC physical link in IMS Connect
Do not stop an MSC physical link in IMS Connect, unless you need to clear the affinity of the link with an IMS system when TCP/IP generic resources are used.
Recommendation: Under normal
circumstances, use the IMS command
/PSTOP to terminate MSC physical links. Stop MSC physical links in IMS Connect only when you need to
clear the affinity of an MSC physical link with a particular IMS system that uses TCP/IP generic
resources.
When you stop an MSC physical link in a local IMS Connect instance by using a command
like STOPMSC, IMS Connect takes
the following action:
- Stops communication on the specified MSC physical link, including communications on all the MSC logical links that are assigned to the physical link.
- Informs IMS that communication has stopped on the physical link so that IMS can also terminate the physical link and any logical links that are assigned to the physical link.
- Changes the status of the MSC physical link and its assigned logical links to NOT ACTIVE.
- For TCP/IP generic resources, clears affinity of a physical link to the IMS system
- Issues message HWSF3305I
Use the VIEWMSC command or the QUERY MSC command to display information about MSC physical links that are defined to IMS Connect.
To stop an MSC physical link in a local instance of IMS Connect:
Procedure
Issue any one of the following IMS Connect
commands in the local IMS Connect
instance:
- In the IMS type-2 format, UPDATE IMSCON TYPE(MSC) NAME(lclPlkid) STOP(COMM)
- In the WTOR format, STOPMSC lclPlkid
- In the z/OS® MODIFY format, UPDATE MSC NAME (lclPlkid) STOP(COMM)
