Monitoring Restarts through the ENFREQ Macro

To monitor automatic restart activity, use the ENFREQ macro to listen for ENF code 38, which MVS™ issues for the following events:

An element was deregistered because of an MVS internal error.
The restart of an element failed.
An element issued the register, ready, or deregister request.
Connectivity to the ARM couple data set is either established or re-established.
An element is deregistered because of an ARM error.
An element is deregistered because of a SETXCF FORCE,ARMDEREGISTER command.

For example, using the ENFREQ macro can help you design programs that have predecessor elements, or help you coordinate automation packages.
