Description

Use the IXLEERSP macro if you are an active connection to a structure in the coupling facility and must provide an asynchronous response to an event exit event (at a time other than when the event exit gets control). Use IXLEERSP to respond to the following specific events reported to your event exit:

Disconnected or Failed Connection event
Existing Connection event for a failed-persistent connection
Rebuild Quiesce event to start rebuilding or duplexing a structure
Rebuild Cleanup event to indicate that resource clean-up for rebuilding or duplexing a structure is complete
Rebuild Stop event to confirm that the system stop the rebuilding or duplexing process
Rebuild Connection Failure event to confirm the failure of a rebuild connection
Structure Temporarily Unavailable event to acknowledge that a system-managed process has been initiated.

For EVENT=DISCFAILCONN, the requestor is able to indicate, using RELEASECONN=YES, that all needed recovery for the failed connector has been performed, and that, as a result, the failed connector need not be made failed-persistent when all confirmations are received. Using PROXYRESPONSE=YES, the requestor is also able to provide a response on behalf of a peer connector that is the subject of a Disconnected or Failed Connection event. The events for which the response can be provided are the Rebuild Cleanup and Rebuild Stop events.

Before using IXLEERSP, the requestor must have set a return code X'08' in the event exit parameter list (IXLYEEPL). See field IXLRCEVENTEXITLATERESPONSE in IXLYCON. Setting the return code indicates, at the time the event is presented to the event exit, that the requestor intends to issue IXLEERSP to respond to the event. If the connector intends to respond to the event asynchronously, the connector must use the IXLEERSP macro.
