How to modify terminals

Terminals and links to terminals can be modified through various type-1 commands. You can use these commands and their variations to manage terminals.

Use the /DISPLAY PTERM and /DISPLAY NODE command to display the status of terminals and nodes. You can also use the /DISPLAY STATUS command, which shows all resources that have a status requiring operator intervention, including terminals and nodes.

Use the /ASSIGN LTERM command to modify the assignment of logical terminals to physical terminals or nodes. The new assignment remains in effect until the next cold start or until you issue another /ASSIGN command.

Use the /DEQUEUE command to discard full-function response-mode output so that the /RSTART command can reset terminal response mode.

You can reset static nodes that are hung in Fast Path input response mode by issuing the /STOP NODE and /START NODE commands in sequence.

Use the /COMPT command for VTAM® terminals (nodes) to notify IMS that a terminal component is operable or inoperable.

IMS provides a VTAM I/O Timeout facility to detect VTAM hung nodes and determine what action, if any, should be taken. Use the /TRACE command to start and stop the VTAM I/O Timeout facility. Use the /IDLE command to deactivate a node and the /ACTIVATE command to activate a node. Use the /DISPLAY command to display all nodes that have I/O outstanding for a time period greater than that specified during system definition.
