Change a subsystem description

The Change Subsystem Description (CHGSBSD) command changes the operational attributes of the specified subsystem description. You can change the subsystem description while the subsystem is active. To change a subsystem description, use the character based interface.

Note: You cannot specify the *RMV value on the POOLS parameter while the subsystem is active, because a job might become suspended.

Command: Change Subsystem Description (CHGSBSD)

Example: This command changes the definition of storage pool 2 that is used by subsystem PAYCTL to a storage size of 1500K and an activity level of 3. The signon display file is changed to display file COMPANYA and is located in the QGPL library. If the subsystem is active when this command is issued, COMPANYA is not used until the next time the subsystem is started.

Change autostart job entries
You can specify a different job description for a previously defined autostart job entry. To change an autostart job entry, use the character-based interface
Change communication entries
You can change the attributes of an existing communications entry in an existing subsystem description by using the character-based interface.
Change job queue entries
You can change an existing job queue entry in the specified subsystem description. This command can be issued while a subsystem is active or inactive. To change the job queue entry in a subsystem, use the character-based interface.
Change prestart entries
You can change a prestart job entry in the specified subsystem description. The subsystem may be active when the prestart job entry is changed. Changes made to the entry when the subsystem is active are reflected over time. Any new prestart jobs started after the command is issued use the new job-related values. This command identifies prestart jobs that are started when the subsystem is started or when the Start Prestart Jobs (STRPJ) command is issued.
Change routing entries
You can change a routing entry in the specified subsystem description by using the character-based interface. The routing entry specifies the parameters used to start a routing step for a job. The associated subsystem can be active when the changes are made.
Change workstation entries
You can specify a different job description for a previously defined workstation entry by using the character-based interface.
Change the signon display
Your system is shipped with the default signon display file of QDSIGNON, which is located in the QSYS library. In situations where you have a multilingual environment, you might want to change what is displayed on the signon screen. Or, perhaps you want to add your company information to the signon screen. In such situations you must first create a new display file. To do so, use the character-based interface.
