****************************************************************
A task makes a remote FC request however all the sessions to
the remote system are unavailable, so the task enters an
allocate wait. Due to the task definition, a DTIMOUT and then
an AAL8 abend occurs. The task then enters recovery and backout.
Since the original request was a file control one, backout
finds a FRTE and so attempts to release it. The task attempts to
unlock the file remotely. However there are still no sessions
available but because we are in backout a DTIMOUT does not
occur so the task hangs forever.

Problem conclusion


    

  • DFHFCFR's recovery routine has been changed. When a file
request had been shipped it will be checked if recovery is
due to an AAL8 abend. If so, the FRTE at the time of the
shipped request will be released.
