IMS sysplex dump considerations

IMS produces SDUMPs for some internal errors without manual intervention. However, IMS Wait/Loop or partial loss-of-function conditions require manual intervention to produce an SVC dump. IMS hangs can be caused by interaction with many address spaces.

The following are considerations for IMS sysplex dumps:

• IMS sysplex implementations need to consider the possibility that a hang or problem on one IMSplex member might be due to a problem originating from another member.
• Problems such as IMS Wait/Loops or partial loss-of-function conditions which require manual intervention to produce an SVC dump, should include SVC dumps from other members of the IMSplex.
• Ensure that a dump is taken for all necessary address spaces on each system.
