How to Protect Your System from User Errors in Servers

At times, a request that an OPSOSF server is executing may fail to complete. A failure may occur for the following reasons:

The request (OPS/REXX program, TSO command, or TSO/E REXX program or CLIST) loops.
The request produces too many responses.
The request waits for an event that never occurs.
The request asks for additional input.
The OPSOSF server is cancelled.
