Released Init 0

Yolanda Harvey · Posted: Thu Aug 11, 2016 8:51 pm

Hi I am a mainframe network programmer and I was doing a network checkout, which I have never done before, after our mainframe was IPLed. An operator pinged me to say he had released INIT 0. I don't exactly know what that meant. Luckily another programmer responded to his query.

I've searched google and this site, but can't find anything to state what this actually means. Can someone explain what release INIT O means?

Welcome!
INIT 0 or INIT 0 MVS, see if that's the context.

Hello Yolanda,

<Adding> OR INIT can also refer to INITiators. Speaking from past experience, seldom the SYSProgs drain the initiators prior an IPL; please note this is a very-very site-specific thing, some sites prefer keeping certain initiators drained until all post-IPL verifications are completed.

As Mr. Sorichetti has stated, your site-support should be able to give you a quicker and more accurate answer.

If an operator is involved, I assume an initiator is being released, but as others have said -- contact your site support group or coworkers as you have given a site-specific term.

I would ask my colleague, but I am his replacement, and asking basic questions are not exactly welcomed. As stated I never had to do an extensive checkout in past job experiences, as the operators always performed those functions.

Does it simply mean that if they have release INIT 0, then no batch jobs can be run? So it would need to be changed if I wanted to run a test job as part of the checkout? Thanks for the replies.

It could mean that the initiator for class 0 has been modified to allow jobs in that class to run. Or, it could mean something entirely. You HAVE to ask an operator or coworker or SOMEBODY at your site about the precise meaning. We can speculate all we want, but we don't work at your site and have no idea of the meaning.

I will definitely ask the operator. Thanks.

Also try to post your answer back here so that anyone else looking for similar question would be benefited.

I thought IPL is a generic stuff used old days during initialization of z/OS and INIT relates to that but I can be wrong in this context so what you say is possibly true and may not be useful for others.

IPL is a generic term in common use by just about every mainframe site. However, in more than 40 years of working as an operator, application programmer, installation specialist, and systems programmer at around twenty sites around the US (and UK), I have NEVER heard the term "release(d) INIT 0" -- and that's the term in question, not "IPL".

Finally able to follow up. I did question the operators on this and he stated that releasing init O (not 0 as I thought) would allow me to run batch jobs after the IPL.

Thanks once again for the help.
