Summary
- Privileges
- System manager
- Function
- Makes unavailable a remote file or scattered group that belongs to a local Parallel Query Option/204 subsystem
Syntax
DISABLE SUBSYSTEM subsysname {[FILE filename | GROUP grpname] AT location}
Where:
| subsysname | is the name of the client subsystem. |
|---|---|
| filename | is the name of a remote file. You cannot specify local files. |
| grpname | is the name of a scattered group. You cannot specify non scattered groups. |
| location | must match the value of a symbolic destination name specified in the DESTINATION parameter of a local CCAD2C process definition. |
Syntax notes
location is required. You cannot specify local files.
Example
DISABLE SUBSYS PQODENV FILE VEHICLES AT DENVER
Usage notes
If a file or group is marked "enabled" to a client subsystem, a user can open the file or group. To make a file or group inaccessible, you must issue DISABLE SUBSYSTEM for the file or group.
If a file or group is disabled because of a communications problem and the problem is resolved, the file or group remains disabled until you explicitly enable it.
You can disable a subsystem file to keep the file itself, or the subsystem to which it belongs, inaccessible for a short period of time, without shutting down the subsystem by using the DISABLE SUBSYSTEM command.
The consequence of disabling a subsystem file depends on whether the file is an optional or mandatory group member:
| If you disable... | Consequences |
|---|---|
| Mandatory file | You effectively disable the subsystem, because users attempting to access the disabled file cannot access the subsystem. |
| Optional file | Users can log in to the subsystem, but cannot access the disabled file. |
