Parameter Description for INITDEF

PARTNUM=nnnn|3
Specifies the number (0-9999) of JES2 logical (batch) initiators to be defined.
  • The actual number of initiators that you can start varies by installation. The maximum number of allowable initiators that can be started depends on factors such as the amount of available auxiliary storage.
  • PARTNUM=3 is the default. If you omit the INITDEF initialization statement from the JES2 initialization stream, "3" initiators are initialized, all set with CLASS=A and START=YES.
  • If you specify PARTNUM=0, JES2 does not define any logical initiators and therefore does not create an associated $PIT.
  • JES2 does not recognize JES2–controlled initiators that are numbered greater than the PARTNUM= specification.

Modification: Single-member warm start.
