PK12008: NO SAMSTL EVENT EYUPN0005W EYUPARM STALLENQTSK 2 STALLENQCNT 1

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• User specified the following EYUPARM in the MAS to request
  RTA SAM stall detection for ENQUEUE waits but no stall
  detection occurs and no EVENT is generated or EYUPN0005W
  message.
  .
  STALLENQTSK(2)
  STALLENQCNT(1)
  .
  In this case 2 or more tasks were in ENQ suspends over 2
  CPSM MAS agent heartbeats but no events were generated.
  .
  The STALL_TYPETABLE in method NLHS only specifies a suspend
  type of KC_ENQ instead of ENQUEUE.

  The STALL_TYPETABLE in module EYU0NLHS (NLHS - MAS Stall Detec-
  tion Agent) specifies a resource type of KC_ENQ instead of
  ENQUEUE for ENQUEUE waits.
  

Problem conclusion

• EYU0NLHS was updated to add several new wait resource types
  which were previously omitted from STALL_TYPETABLE.
  

Temporary fix

• FIX AVAILABLE BY PTF ONLY
  

Comments

• You enter nonzero values for the STALLENQTSK and STALLENQCNT
  EYUPARMs to enable CPSM stall detection for ENQUEUE waits
  but no stall detection occurs and no EVENT or EYUPN0005W
  message is generated for !!SAMSTL with type ENQUEUE.  In
  this case two or more tasks were in ENQUEUE suspends over
  two CPSM MAS agent heartbeats but no events were generated.
  
  The STALL_TYPETABLE in module EYU0NLHS (NLHS - MAS Stall Detec-
  tion Agent) specifies a resource type of KC_ENQ instead of
