PK07380: WHEN CEMT DISCARD WEBSERVICE IS ENTERED TWICE, CPIH HANGS IN LMQUEUE WAIT FOR LOCK PIWEBSRV.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If there has been at least one WEBSERVICE installed then the
  PIWEBSRV lock will be obtained exclusively. After that, a
  directory lookup is done to find the requested WEBSERVICE,
  which failes because the WEBSERVICE is not found. The not
  found response is returned and the routine exits without
  ever releasing the lock.

  ****************************************************************
  CEMT DISCARD WEBSERVICE is issued for a WEBSERVICE that does
  not exist.  If at least one WEBSERVICE has been installed in
  this CICS region then CEMT will hang.  The hang is caused by
  CEMT trying to obtain the PIWEBSRV lock in SHARED mode while
  already holding it in EXCLUSIVE mode.  The lock is still held
  exclusively because DFHPIWR failed to release it when the
  DISCARD WEBSERVICE failed and returned NOTFND.
  
  The same problem exists with any application issuing DISCARD
  WEBSERVICE followed by INQUIRE WEBSERVICE where the WEBSERVICE
  being discarded does not exist.
  
  Once the lock is held exclusively and not released all
  operations involving WEBSERVICEs will hang waiting to acquire
  the PIWEBSRV lock.
  

Problem conclusion

• DFHPIWR has been changed to release the PIWEBSRV lock before
  returning with a not found condition.
