IMS Automated Operator Interface (AOI)

The IMS Automated Operator Interface (AOI) lets an application program, using DL/I calls, issue most IMS operator commands and receive command responses.

AOI lets you write an exit routine to intercept:

• IMS system messages routed to the MTO
• Commands
• Command responses

Using AOI, you can examine these messages, commands, and command responses and issue a message to any terminal or to the IMS message queue to be processed by an application program.

You can use AOI to develop commands tailored to your installation and to automate some portions of the recovery process. AOI can relieve the MTO of numerous controlling and monitoring duties. This is especially useful if you manage a large terminal network. IMS can send single segment or multi-segment messages. Your AOI exit must be able to handle both types of messages in the event that messages run over one line.

Using AOI:

• Relieves operators from repetitive command entry.
• Increases accuracy for command entry, especially when the commands have LTERM and telecommunication line control parameters.
• Helps you control IMS resources at prearranged times, such as during region startup and database image copy.
• Lets you prompt the MTO to take specific actions.
• Allows entry of commands with long operand lists. This can be important for commands that are larger than can be entered from a terminal.

Automated operator programs can:

• Supervise terminals
• Control IMS monitor and trace operations
• Help detect database problems
• Assist in recovery by issuing the commands /STOP DB, /LOCK DB, and either the /DBRECOVERY DB or UPDATE DB STOP(ACCESS)
