PM63847: The value of statistic CS_IAVRESP written to SMF might be incorrect.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If multiple CICS servers are in use, CS_IAVRESP (average CICS
  response time) is calculated from the number of requests flowed
  to a single CICS server, and an incorrect value of 0 is written
  to SMF. However if CS_IAVRESP is collected through the SDSF
  interface (by using the command
  "/F <jobname>,APPL=STATS,GS=CS_IAVRESP"), or through the
  statistics API, the returned value is correct.

  ****************************************************************
  Interval statistics are calculated, written to SMF, and reset
  ready for the beginning of the next interval. If multiple CICS
  servers were defined, CS_IAVRESP was calculated using the
  number of requests flowed to only one of the defined CICS
  servers. This caused the value of CS_IAVRESP that was written
  to SMF to be incorrect. When retrieving a value for CS_IAVRESP
  using the SDSF interface or the statistics API, the value
  returned was correct.
  

Problem conclusion

• CICS TG has been corrected. The number of requests sent to all
  defined CICS servers is used when calculating the value of
  CS_IAVRESP.
