DFS1917I INVALID CID
Explanation
VTAM® used an invalid control interval definition (CID), or the CID in the IMS control block was overlaid. The NODE name cannot be found for the session initiation.
System action
IMS rejected the VTAM entry to one of the IMS exits and returned to VTAM with an error code. IMS continues.
Operator response
See the Programmer response.Programmer response
Determine whether VTAM has operational problems. If possible, create a snap memory dump of the IMS CLB control blocks to determine if any of them are overlaid.
