Setting special processing modes
After user signon, you can set the following processing modes by using IMS commands.
- Exclusive mode
- /EXCLUSIVE command
- Preset destination mode
- /SET command
- MFS test mode
- /TEST MFS command
- Test mode
- /TEST command
These special processing modes, except for the test mode and the preset destination mode, are retained for the user after signing off and are reestablished with the next terminal on which the user signs on.
When you issue the following commands, IMS creates the required control
blocks for a terminal or user, or it maintains a user's status:
- /EXC USER
- Places a user structure in exclusive mode.
- /STOP NODE or /STOP USER
- Stops a node or user structure.
- /TEST MFS USER
- Places a user structure in MFSTEST mode. When a user signs on, IMS places the terminal in MFSTEST mode, if the terminal supports MFS.
- /TRACE NODE
- Traces a logged-on node.
Control blocks are not immediately deleted when special status is removed. They are deleted at the next checkpoint if they meet all deletion requirements. If an outstanding status exists, they are not eligible for deletion.
To reset terminal status
and make the control blocks eligible for deletion at the next simple
checkpoint, use the following commands:
- /END
- Clears exclusive and test modes.
- /RESET
- Removes the preset destination.
- /RSTART
- Starts stopped resources.
- /START
- Starts stopped resources. For other status reset by the/START command, see IMS Version 15.5 Commands, Volume 2: IMS Commands N-V.
- /TRACE
- Sets trace off.
Use the preceding set of commands if the control blocks exist solely for status retention.
You can use the Signoff exit routine, DFSSGFX0, to reset these states.
