Problem summary

  • ****************************************************************
* USERS AFFECTED: All users of IBM Common Data Provider for z  *
*                 Systems v1.1.                                *
****************************************************************
* PROBLEM DESCRIPTION: High CPU in Log Forwarder when          *
*                      collecting joblog data.                 *
****************************************************************
* RECOMMENDATION: Apply this PTF.                              *
****************************************************************
When collecting joblog data and 1 byte remains in the collection
buffer, a loop may occur, causing high CPU.

Problem conclusion

  • Log Forwarder code has been changed to recognize the single byte
remaining condition and prevent the loop.  JES2 APAR OA61894 for
z/OS V2R3 (or the equivalent for other z/OS releases) may also
be applied for this condition.
