When things go wrong - Recovery scenarios for system logger

This information describes some of the failures that can affect system logger applications and the action taken by system logger in response.

System logger performs recovery differently for DASD-only versus coupling facility log streams. Recovery for DASD-only log streams need to be done by the application. Therefore, most of the information applies to coupling facility log streams only. For DASD-only log streams, see Recovery performed for DASD-only log streams. Other recovery information pertinent to DASD-only log streams are noted under each topic below.

For many of the failures, an application can listen for an ENF 48 event to find out when problems are resolved or resources are available again.
