Function

To start one or more initiators.

Parameters

ASID=asid

The initiator associated with the specific address space is to be started.

I[init[-init]]

Specifies the subscript (1-9999) of the initiator(s) that are started.

Note:

1. If you omit the initiator identification (vvvv), JES2 starts only those initiators stopped by a prior $Z I or $P I command that also did not specify an identifier. For example, note that if initiator 1 was stopped with the $P I1 command and is later to be restarted, you must issue $S I1; issuing $S I will return message $HASP000 OK, but initiator 1 is not restarted.

   If JES2 is started with the option START=NO on the INIT statement, a $SI will not be successful. In such case, the $SI command needs to be qualified with a specific or range of initiators like $SI (1–*) for example. $SI unqualified will only work if a previous $PI or $ZI was issued.

2. JES2 commands do not recognize JES2–controlled initiators that are numbered (with subscripts) greater than the PARTNUM= specification on the INITDEF initialization statement.

For information about naming initiators, see z/OS JES2 Initialization and Tuning Reference, SA32-0992.

STATUS[=ACTIVE|DRAINED|DRAINING|HALTED|HALTING |INACTIVE|RESTARTING|STARTING}

Initiators in the specified state are to be started. The following types of status can be displayed:

Type

Meaning

ACTIVE

A job is active on the initiator

DRAINED

The initiator is drained

DRAINING

The initiator is transitioning to a DRAINED state

HALTED

The initiator has been halted by the $Z I command

HALTING

The initiator is transitioning to a HALTED state

INACTIVE

The initiator has been started but has not selected a job

RESTARTING

The initiator has terminated abnormally and is in the process of restarting automatically

STARTING

The initiator has been started but has not fully initialized yet

STC=stc

The initiator associated with the specific STC that is to be started.

Authority Required

This command requires system authority. The description of the $T RDRnn command explains how to ensure that the authority of the appropriate MVS™ system command group is assigned.

This command requires control security access authority. For a description of assigning command input authority, see z/OS JES2 Initialization and Tuning Guide, SA32-0991.

Scope

Single member. This command will be in effect for this member only. There is no need to have this command issued to all members of the MAS.

Messages

The $HASP892 message indicates the command was accepted.

When the initiator starts processing a job from the job classes assigned to it, JES2 issues the $HASP373 message.

Initiator 3 (X'404040F3') begins processing jobs from the job classes assigned to it.
