Designing for Recovery

When a connector to a coupling facility lock structure fails, the following occurs:

XES reports the failure event to all surviving connectors.
The surviving connectors must respond to the event.
When all responses have been received by XES, XES performs its cleanup.

As part of your recovery protocol, you might require that connectors do their application-specific cleanup before responding to the connection failure event.

Your recovery protocol has several dependencies:

How connections are defined at connect time
How recovery information is used for peer and restart recovery.
