The IMS Operations Facility (IOF) is an interface between CA OPS/MVS and IMS that extends the CA OPS/MVS facilities to IMS. For example, you can write AOF rules that process IMS messages, and you can use OPSVIEW to operate IMS.
A single copy of CA OPS/MVS can handle up to 32 copies of IMS. If you run multiple copies of IMS under the control of one copy of CA OPS/MVS, the copies of IMS may be any combination of IMS levels that CA OPS/MVS supports.
The IOF interface enables CA OPS/MVS to seamlessly integrate IMS control regions with the CA OPS/MVS operation of z/OS and JES. IMS requires its own master terminal, which receives most IMS related messages. The IOF interface dynamically inserts an IMS Automated Operator (AO) exit to capture the IMS command and message traffic, and also identifies and captures z/OS messages that are associated with the IMS. It provides integrated support for IMS DB/DC, data communication control (DCCTL), and database control (DBCTL) environments.
To issue IMS commands and retrieve command responses, the IOF interface can use a batch message processing (BMP) region, if it is available, or it can use the IMS write-to-operator-with-reply (WTOR) method when it needs to issue an IMS command.
