STOP SUBSYSTEM subsysname [FROM location]
Where:
| subsysname | The name of the application subsystem, comprised of a maximum of ten characters. |

Usage notes
If the STOP command is issued when there are no active users in the application subsystem, the subsystem is completely stopped. The subsystem frees the core-resident control blocks and the CCATEMP pages associated with precompiled procedures. All enqueued procedures and file groups are released and all subsystem files and groups are closed.
If the STOP command is issued with active users in the subsystem, the application subsystem facility sets the application subsystem to the drain state. Other users are barred from entering the subsystem. When the last user leaves, the subsystem is completely stopped.
