When a resource manager percolates to the recovery environment of system logger, it is disabled with abend X'x22', regardless of whether it had the opportunity to retry. When this happens, the resource manager must disconnect from the log stream and then reconnect in order to activate the resource manager exit.
When a resource manager is disabled, an ENF 48 event is issued on the system where it is disabled. If an SDWA is available to system logger's recovery routine, the abend code is included in the ENF parameter list mapped by macro IXGENF.
The resource manager should examine the abend code and decide whether to disconnect and terminate or to disconnect and reconnect to the log stream.
