Changing 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 sign-on 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.
