HPIO control statement

Specifies whether the IPR Reload utility uses High Performance I/O Driver for output database data sets.

This control statement is optional. If you do not specify this control statement, the value for the HPIO option is determined as follows: If the libraries specified on the STEPLIB DD statement are not APF-authorized, HPIO=NO is used; otherwise, HPIO=YES is used.

YES
High Performance I/O Driver is used for output database data sets.
NO
High Performance I/O Driver is not used for output database data sets.
Notes:
  • For HISAM or SHISAM data sets, HPIO=NO is assumed. If you specify HPIO=YES, it is ignored. If HPIO=NO is specified, the APF authorization of libraries specified in STEPLIB DD is not necessary.
  • If you want to specify the HPIO control statement for the all subtasks of the Smart Reorg utility, including the IPR Reload utility task, it is recommended that you specify the HPIO control statement in the (REORG) block. In this case, the specification of the HPIO control statement in the (RELOAD) block is ignored. If you want to specify the HPIO control statement for each subtask of the Smart Reorg utility, you must not specify the HPIO control statement in the (REORG) block explicitly. For more information about the HPIO control statement for the (REORG) block, see HPIO control statement.
Tip: You can change the default value of this control statement by creating an Installation Default Option Table (HPSCOPTI). For more information, see Setting installation default options.
