DFS3877I JOINRSE FAILED

Explanation

The IMS system failed to register as either the active system or the alternate system of an XRF complex. The name of the recoverable service element (RSE) can be found on the RSENAME parameter in the DFSHSBxx member of PROCLIB.

In a Fast Database Recovery environment, the subsystem name of the active IMS is used as the RSE. When this message is issued by the active IMS, I/O prevention is not invoked in case of IMS failure. The Fast Database Recovery region does not issue this message.
