$ACTIVE – Specify processor is active

z/OS JES2 Macros
SA32-0996-00

Use $ACTIVE to indicate to JES2 that the associated processor is performing activities for the JES2 main task; this prevents JES2 from being cleanly withdrawn from the system (through $P JES2) when JES2 is processing a job or task.

Format description


>>-+--------+--$ACTIVE--+----------+---------------------------><
   '-symbol-'           '-R=--R--n-'

R=

Specifies the work register which is to be used by the $ACTIVE macro instruction. Do not enclose the register (R=) value in parenthesis. Register 1 is the default.

Note:

JES2 is considered active when the active count is greater than 0 ($DORMANT decreases the active count). When the active count is 0, JES2 issues $HASP099.
Do not use R=0.

Environment

Main task.
$WAIT cannot occur.
