Preventing Startup Program from Running

Problem

This document describes how to prevent the system startup program from running.

Resolving The Problem

This document addresses how to prevent the startup program from running after starting the controlling subsystem or after the system is IPLed.

In the QCTL controlling subsystem, there is an auto job entry called QSTRUPJD. It runs as soon as the QCTL is started. In the QSTRUPJD job description, a request data CALL QSYS/QWDAJPGM retrieves system value QSTRUPPGM. The program that is specified in the system value will run. If system value QSTRUPPGM is set to *NONE, there is no startup program to call.

To change the system value, on the operating system command line type the following:

CHGSYSVAL SYSVAL(QSTRUPPGM) VALUE(*NONE)

Press the Enter key.

The help text on the operating system for the system value includes the following:
 
A change to this system value takes effect the next time the system is IPLed. The shipped value is QSYS/QSTRUP.
