PH39776: EYUNL0913I COUNT IS NON-ZERO WHEN THE COUNT IN EYUNL0912I IS ZERO

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• At MAS agent termination time, CPSM issues messages about the
  use and high water mark for alternate long running tasks in a
  MAS. Those counts can be inaccurate and misleading between
  messages EYUNL0913I and EYUNL0912I as in the following
  .
  EYUNL0911I Number of active alternate LRTs : 4.
  EYUNL0912I Maximum concurrently busy alternate LRTs : 0.
  EYUNL0913I Number of times all alternate LRTs were busy: 1.
  .
  Note that it does not make sense that the count in EYUNL0912I
  is zero if the count in EYUNL0913 is non-zero.

  ****************************************************************
  * PROBLEM DESCRIPTION: Message EYUNL0913I may incorrectly show *
  *                      a non-zero value, when EYUNL0912I is    *
  *                      zero when alternate long running tasks  *
  *                      are used (MASALTLRTCNT).                *
  ****************************************************************
  EYUNL0913I shows the number of times all alternate tasks were
  busy. EYUNL0912I displays the maximum number of alternate tasks
  which were busy concurrently. It is expected that for EYUNL0913I
  to show a non-zero value, EYUNL0912I should show the number of
  alternate long running tasks. However, if work that can run on
  an alternate long running task (such as WUI and CPSM API
  requests) comes into the MAS agent, while the MAS agent is
  terminating, the value used for the count on EYUNL0913I,
  CTRB_NLRA_BUSY_ALL, is incorrectly incremented if the alternate
  tasks have already been terminated. This results in EYUNL0913I
  to incorrectly show a non-zero value, e.g. :
    +EYUNL0911I Number of active alternate LRTs : 2.
    +EYUNL0912I Maximum concurrently busy alternate LRTs : 0.
    +EYUNL0913I Number of times all alternate LRTs were busy : 1.
  

Problem conclusion

• The incorrect incrementing of CTRB_NLRA_BUSY_ALL used for
  EYUNL0913I has been corrected for the cases where alternate
  long running tasks have been terminated during MAS agent
  termination.
