PI09362: DFHFC0999 : CICS NEVER RECONNECTS TO RLS FOLLOWING A DYNAMIC RLS RESTART. 14/01/22 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A CICS region remains up while the DFSMS RLS server is brought
  down and restarted. Dynamic RLS restart begins but does not
  end.  Access to RLS files from this CICS region remains
  disabled.
  .
  This CICS region issues the following message when dynamic RLS
  restart begins:
  .
  DFHFC0568I CICSPRD1 File control dynamic RLS restart has
  started.
  .
  But this CICS region never issues the message DFHFC0569I saying
  that dynamic RLS restart has ended.  And it never issue the
  message DFHFC0570 saying that RLS access is enabled.
  .
  In this state when there is an attempt to open an RLS file from
  this region, the following message is issued:
  .
  DFHFC0999 CICSPRD1 RLS OPEN of file FILERLS1 failed. RLS access
  is disabled.
  .
  Earlier in the log, this CICS region issued the following
  message:
  .
  DFHFC0001 CICSPRD1 An abend (code 058/AKEX) has occurred at
  offset X'4D7A' in module DFHFCRO.
  .
  
  In the DFHFC0001 dump you can see that this abend058 happened
  while a file ABCDFIL1 was being closed.
  .
  In a dump taken later, you can see that there is a CSFR task
  that is in a FCACWAIT *CTLACB* wait.  This task is waiting for
  all open RLS files to close.  In FC=3 you can find the FC
  Static area.  +3B8 into that is FC_RLS_ACB_CHAIN which is the
  anchor for a chain of open RLS files.  File ABCDFIL1, the file
  involved with the Close that resulted in abend058, is on that
  chain. Because of the abend while closing the file, the file
  will never completely close and CICS will never be able to
  reconnect to RLS.
