Error description

• After modifying a WLMDEF used for workload separation by LUNAME
  to update the generic and wildcard name, all WLM users receive
  message:
  .
  EYUWR0104E CPSM Reports an unexpected error on FUNCTION SM_SCOPE
  .
  The CMAS auxtrace contains exception trace entries as follow:
  .
  XCLF WTCL TSSO CHE EXCP.     40 INVLSTID
  WTCL WASV TSSO WLM EXCP.      1 FINDWMIP
  WASV WDTR TSSO WLM EXCP.      1 WASVWTCL
  WDTR XLOP TSSO WLM EXCP.     11 WDTRAPIE
  .
  A dump taken of the environment including the WLM dataspace
  indicates the old LUNAME pattern still exists in the major
  pattern cache list.
  .
  Examining the WTCL stkfrm indicates the matching WMAP_KEY
  returned at x'35C' is the old generic LUNAME pattern which
  should have been removed when the WLMDEF was reinstalled after
  the updated changes to a mixed wildcard and generic pattern.
  The WMAP_MINOR_LID returned at x'374' into the stkfrm is no
  longer valid resulting in the INVLSTID XCLF failures.
  .
  
  Method WMWI should have requested the removal of the old major
  pattern element at label WMWI_DSC_MAJ .  This code path results
  in the WMAP_MINOR_LID being deleted and finally the WMAP entry
  itself being deleted by method XCLR.
  .
  The XCLR method call from WMWI just past label WMWI_DSC_MAJ can
  result in a RECORD_NOT_FOUND status even though the previous
  XCLF found the record.  The logic path within method XCLR for
  deleting from a generic cache list just past label VAL_KEY_GEN
  issues an EXECUTE instruction for the TRANSLATE using label
  MAIN_GENERIC_XLATE and R15 for the length of the TRANSLATE.
  R15 points to the record key address...not the key length.
  In this case the key length is 17 bytes but the last byte of
  the record key address in R15 is zeros.  The EX instruction
  for the TRANSLATE will only translate the first byte of the
  WMAP_KEY so the trailing x'5C' '*' will remain in the
  WRK_SRCHARG area beginning at x'2D4' in the XCLR stkfrm.
  .
  The EXECUTE instruction should use R1 which contains the
  key length already decremented by 1 for the TRANSLATE.

  ****************************************************************
  Problems may occur when using a WLMDEF to perform workload
  separation by LUNAME using a generic pattern. If the generic
  pattern is updated to make it less specific (for example,
  changing the pattern from HA17* to +A17*) may result in message
  EYUWR0104E.  A logic error exists in method EYU0XCLR (XCLR -
  Delete Search List Element Method Receiver), which can prevent a
  cache list element from being removed from the cache list.
  

Problem conclusion

• XCLR has been changed. An incorrect register was used on an
  EXECUTE instruction. The EXECUTE instruction for the TRANSLATE
  uses R15 for the length of the TRANSLATE.  This is incorrect.
  R15 points to the record key address. R1 contains the key length
  and should be used for the length of the EXECUTE instruction.
