PH35135: ABEND0C9 IN IWXCTRXF CAUSED BY FIXED POINT DIVIDE EXCEPTION WHEN ATTEMPTING TO CALCULATE PATH ROUTING INDICES

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• ABEND0C9 in IWXCTRXF caused by fixed point divide exception when
  attempting to calculate path routing indices, that is when WLR
  is figuring out which path to use based on GOALS when values
  such as:
  - Total number of transactions processed: 4,294,888,843
  and
  - Number of transactions processed by the LOCAL/IMSG path:
    4,126,489,049
  are encountered.
  

Local fix

• Issue the /FORMAT IWXADM LEVEL command to zero out these
  counters until a PTF is available to fix this problem.

  ****************************************************************
  ABEND0C9 in IWXCTRXF caused by fixed point divide exception when
  attempting to calculate path routing indices, that is when IMS
  Workload Router is figuring out which path to use based on GOALS
  when values such as:
  - Total number of transactions processed: 4,294,888,843
  and
  - Number of transactions processed by the LOCAL/IMSG path:
    4,126,489,049
  are encountered.
  This problem has been resolved by APAR PI25916, but the IMS V14
  and IMS V15 modules in IMS Workload Router do not have the fix
  for it yet.
  

Problem conclusion

• IMS Workload Router has been changed to reset the transaction
  counters when they are about to exceed 2,147,483,647
  (x'7FFFFFFF').
  At that time, the system messages IWX601I and IWX607I are
  issued.
  This fix is forward fit of PI25916 for IMS V14 and IMS V15
  modules in IMS Workload Router.
