PM73364: NEW SET COMMAND SUBTASK-DATASET-EXTENSIONS

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• This enhancement allows dataset extents to be processed in any
  available subtask. Previously, all extents were always processed
  after the initial (A001) dataset and in the same subtask. If
  there are a significant number of extents to be processed by the
  target job, this might be an option to consider to improve the
  total elapsed time of the target job. If DB2 START commands
  starts are enabled for target objects, they will be done when
  the last extent of an object has been processed, regardless of
  the subtask used. The number of subtasks must
  be greater than one for this to be a useful feature.
  
  There are several restrictions when using this enhancement...
  #1. no log apply
  #2. no data masking
  #3. no runtime repository
  #4. no DB2 STOP commands in the target job (via the PARMLIB
      parm, AUTO_STOP_TARGET_SPACE)
