If you decide that you do not want the servers to use the prestart job function, you must follow these steps.
Prestarted jobs ended with the ENDPJ command will be started the next time the subsystem is started if start jobs *YES is specified in the prestart job entry or when the STRHOSTSVR command is issued for the specified server type. If you only end the prestart job and do not perform the next step, any requests to start the particular server will fail.
The prestart job entries removed with the RMVPJE command are permanently removed from the subsystem description. After the entry is removed, new requests for the server will be successful, but will incur the performance overhead of job initiation.
