On systems with OW38840 installed or which are at OS/390® Release 9 and higher, a connector to a cache structure may request that the system suppress certain connection and disconnection events generated by the connector. The Disconnected or Failed Connection event is one of the events that can be suppressed. If a cache structure connector has specified SUPPRESSEVENTS=YES and subsequently disconnects or fails, peer connectors will not receive the Disconnected or Failed Connection event and therefore will not provide the required response. Instead, the system immediately performs the cleanup that would have been performed after all responses to the event had been received, if the event had not been suppressed. See Suppressing Certain Events for a Connector for information about event suppression.
