OA41986: WHEN RUNNING THE RESOURCE COMMAND, AUTO2 MAY HANG SHOWING A COMMAND OF PIPE1. 13/04/15 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Customer was seeing AUTO2 hanging and TASKUTIL showed a command
  of PIPE1.  A LIST AUTO2 showed the task was running MEMSTORE.
  MEMSTORE is set up to run on a timer basis and it issues the
  RESOURCE command from a PIPE named PIPE1. The resource command
  was running into a problem when subtracting the parked time from
  the total CPU time and coming up with a negative value. This
  may happen when a CPU is varied offline, the parked time is not
  reinitialized when the CPU is varied offline.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All Tivoli NetView for z/OS users of the     *
  *                 RESOURCE command with PTF UA68294 installed. *
  ****************************************************************
  * PROBLEM DESCRIPTION: When running the RESOURCE command, the  *
  *                      task on which it is running may appear  *
  *                      to hang. Issuing the TASKUTIL command   *
  *                      will show that over time the 'hung'     *
  *                      task is using CPU time.                 *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The RESOURCE command collects CPU timing data from system
  control blocks on initial entry, waits for about one second and
  then makes a second collection of CPU timing data. If between
  the first and second collections there is a change in the number
  or status of the CPUs from the first collection, the RESOURCE
  will cycle to make another set of collections. The RESOURCE
  command is not resetting one of its data accumulators which
  causes the RESOURCE command to cycle to make another set of CPU
  timing data collections. This cycling will occur once every
  second until the RESOURCE command is canceled or the task is
  terminated.
  

Problem conclusion

• The RESOURCE command is being changed to reset the data
  collection variable which is causing the data collection
  cycling to occur.
