DFS4888I UOW LOCK NOTIFY RECEIVED TIMEOUT RESPONSE FROM ims_id

Explanation

In a Fast Path environment, the IRLM notify process is used to notify all of the IMS subsystems in an IMS sysplex of a request. An IMS system waits until all other IMS systems in the sysplex respond to the IRLM notify process. Or, an IMS system waits until a timeout response is returned to the notify process, and then the request is terminated by the IMS system that initiated the request.

This message was issued because an IMS system in an IMS sysplex sent a unit of work (UOW) lock mode transition message to other members of the sysplex for high-speed sequential processing (HSSP) or high-speed reorganization (HSR). A timeout then occurred in the UOW lock mode transition process, and a timeout response was returned by the IMS system ims_id to the IRLM notify process. This indicates that the IMS system ims_id is holding CI locks on the area data set.
