MONITOR command: Subsystems

Summary

Privileges

System administrator

Function

Displays a list of active subsystems and information about those subsystems.

Syntax

MONITOR SUBSYSTEM [(option [[,] option]...)] {name [FROM location] | LIKE' pattern' [FROM 'loc-pattern']}

Where:

name	The name of a subsystem.
location	In information about Parallel Query Option/204 service subsystems, the value of the client CCAIN LOCATION parameter. location is also the value of the CLNT field in the LOGWHO command output.
LIKE pattern	Displays the specified information for subsystems whose names match the designated pattern. The pattern must be enclosed in single quotes. An asterisk (*) finds all.
loc-pattern	In information about PQO service subsystems, matches a client CCAIN LOCATION parameter. An asterisk (*), meaning all nonlocal locations, is a valid value for loc-pattern. If you use this pattern matching, you must specify a pattern for both the subsystem name and location, and you can only match remote location names.
option	A term from the "MONITOR SUBSYSTEM options" table, below (options must be enclosed in parentheses).

Usage notes

If you have both client and server subsystems, you can monitor both, but only one at a time:

• FROM location looks only for server subsystems.
• A name only or loc pattern looks only for client or local systems.
