XCF does not provide any recovery for the message notify user routine. Routines that require recovery must establish their own. XCF does place sufficient information into the SDWA to identify the message notify user routine that was in control. The multi-system application must provide whatever diagnostic data is required for problem determination for the message notify user routine.

• For a message notify user routine that receives control as a standard XCF-managed SRB routine, SRB-to-task percolation might occur, just as for a message user routine.
• For a message notify user routine that receives control as a result of invoking the IXCMSGC Call Exit service, percolation from any recovery routine established by the message notify user routine causes XCF's recovery to percolate to the recovery established by the IXCMSGC invoker.
