Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• Allow the REMDSREC parameter to be used in TWSz 9.2 release,
  to remove CP16 records from the current plan in the event
  that RCLEANUP(YES) was specified for the controller parms but
  RCLEANUP(NO) was inadvertently coded in the BATCHOPT parm.

  When RCLEANUP(YES) parameter is specified in BATCHOPT and
  RCLEANUP(NO) parameter is specified in OPCOPTS, the CP16
  records are never removed from the current plan.
  A new parameter, REMDSREC, can be specified in BATCHOPT
  to remove these records from the current plan.

Comments

• The new parameter, REMDSREC, has been added to remove CP16
  records from the current plan.

  |The following parameter must be added to the above section:  |
  |REMDSREC (YES NO)                                            |
  |Controls if the daily planning program ignores and does      |
  |not carry forward any CP16 data store records that           |
  |accumulated. Typically, use the value NO (this is also the   |
  |default). If you need to set this parameter to YES, change it|
  |back to NO as soon as possible.                              |
  |CP16 data store records accumulate in several situations,    |
  |for example when the RCLEANUP parameter of BATCHOPT and the  |
  |RCLEANUP parameter of OPCOPTS are set to different values.   |
  |Usually, these two RCLEANUP parameters are either both set   |
  |to YES or both set to NO. However, if RCLEANUP(YES) is set   |
  |in BATCHOPT and RCLEANUP(NO) is set in OPCOPTS, the          |
  |CP16 records accumulate over the period that RCLEANUP(NO)    |
  |is specified for the controller task. This occurs because    |
  |the CP16 records are created by the batch job, but they are  |
  |never processed or deleted by the controller. Later, when    |
  |you set RCLEANUP(YES) also for the controller, the           |
  |controller performance might significantly decrease and      |
  |return to normal after a long time, or the controller might  |
  |run out of storage and end with ABEND S878.                  |
  |When you set REMDSREC=YES, accumulated CP16 records are      |
  |deleted and message EQQ0548I is issued in the message log.   |
