DFS3873I JOINRSE MODE=ACTIVE|BACKUP WAS SUCCESSFUL

Explanation

An IMS system was successfully registered with the Availability Manager as either the active system or the alternate (backup) system of an XRF complex. To the Availability Manager, the XRF-capable IMS system is a recoverable service element (RSE) consisting of both an active system and an alternate system. The name of the RSE that this IMS system is "joining" 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 an IMS system that is enabled for Fast Database Recovery issues this message, it is ready for I/O prevention invocation. The Fast Database Recovery region does not issue this message.
