PK78894: DFHSM0133 CICS SHORT ON STORAGE. CPSM TRANSACTION COVC IN LOOP, USING ECDSA STORAGE.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If CPSM program resource EYUTVTME is not defined in CICS region,
  and transaction COVC attempts to issue a message, it will get
  into a loop and cause the region to go SOS.  The storage will be
  out of the ECDSA.  Browsing the storage you will see the
  following in the eye-catcher area
  .
        EYUBVKSBSTAKHDR
  .
  and repeated messages
  .
        EYUVS0120E UNABLE TO LOAD RESOURCE TABLE (EYUTVTME).

  ****************************************************************
     Module EYU0VCTL (VCTL - WUI Terminal Control transaction)
  calls EYU0VCTR (VCTR - Manage WUI Control Main Menu) to display
  the primary menu and handle user requests.  VCTR must retrieve
  strings from one of the NLS string table modules to complete
  the main menu screen definition.  Non-NLS Message EYUVS0121W is
  written to the console if the target language cannot be deter-
  mined from an INITPARM, and an attempt is made to load the ENU
  string table module, EYUTVTME.  The load fails because the WUI
  resource group EYU310GW is not installed.  This causes non-NLS
  message EYUVS0120E to be written to the console and the COLG
  transient data queue (EYULOG).  The WRITETD fails because COLG
  is defined in group EYU310GW.  This causes message EYUVS0150E
  to be sent to the console and joblog, but EYUVS1050E is an NLS
  message and requires strings from the appropriate NLS string
  table.  This results in a recursive call to EYU0VMSB (VMSB -
  WUI String resource Lookup).  The process continues until the
  region goes short on storage and the COVC task is unable to
  GETMAIN an additional block of storage for stack.
     When an overflow stack block is required, module EYU0VKES
  (VKES - GETMAIN Storage to Extend WUI Stack) is called to get
  and format a block of storage as a stack extension.  VKES also
  writes a USER trace record but the trace identifies VKES as the
  active method and the calling method, making it difficult to
  identify the real requestor.
     The CPSM dump verb exit EYU9D310 issues message EYUDV0106E
  and terminates if a valid Kernel Linkage Work Area (XLWA)
  cannot be located in the dumped region.  However the WUI may
  write trace records in the CPSM format in a region without an
  XLWA.  EYU9D310 should be able to format these trace records.
  

Problem conclusion

•    Module EYU0VCTL was modified to inquire on the status of
  transient data queue COLG and transaction COVG (the CPSM WUI
  Global Long Running Task).  If either of these resources is
  not found, or is not ENABLED, the COVC transaction issues non-
  NLS message
  .
     EYUVS0999S  WUI FAILED: VCTL: MISSING RESOURCES :
                 resp,status
  .
  indicating that an internal error occurred.  Inserts "resp" and
  "status" are the EIBRESP and enable status returned by INQUIRE.
  The task then ends without attempting to access any additional
  resources.
     Module EYU0VKES was modified to copy the last four characters
  of the calling module name from the caller's stack header into
  the trace record being constructed.
     Copy module EYUBDVKE (CPSM Verb Exit Keyword Table Entry Map)
  was modified to define a new bit flag identifying options which
  do not require a valid XLWA to process.  This flag was set for
  the TRC keyword in module EYU0DVKW (DVKW - Verb Exit Keyword
  Parser).  Module EYU0DVJF (DVJF - Verb Exit Job Format Driver)
  was also modified to process keyword options for which a valid
  XLWA is not required, if an XLWA cannot be found in the dump for
  the current job.
