Authority Required

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

Processing Considerations

The following restrictions apply to all monitor commands. They:

Can only be issued through the MVS command interface (consoles or MGCRE) or JES2 automatic commands
Cannot be issued from the JES2 initialization data set, NJE/RJE, $M commands, or through a reader (INTRDR)
Can be the object of a $VS command
Are not limited by CONDEF CMDNUM=
Are not limited by CONDEF DISPMAX=
Support L= for directing the output but do not honor CONDEF RDIRAREA= or REDIRECT= parameters
Cannot use the JES2 command separator, semicolon (;), to separate monitor commands unless it is also the MVS command separator.

Scope

Single Member. This response to this command displays of information about this member only.

Status in the $HASP9100 message is one of:

ACTIVE– Subtask is active and processing normally.
INITIALIZING– Subtask is still completing its initialization processing (or is reinitializing after a failure.)
TERMINATING– Subtask is in the process of shutting down.
TERMINATED– Subtask has shut down.

Alerts are based on the individual subtask and the functions they perform. Alerts include:

AWAITING JES2– The JES2 address space is not active; therefore, the subtask is not performing its normal function.
RECOVERING– The subtask has ABENDed and is in the process of recovering.

The module information in the $HASP9102 display includes the name of the module, where it is located in the monitor address space, the length of the module (in hex), the date and time the module was assembled, and information on what maintenance was applied to the module.
