Is it possible to abort system start during SYSTEM^%ZSTART?

If some conditions are not met, I want to shut down IRIS instead of continuing with the startup.

In some way, I wonder about your question. This is a very specific question and a correct and accurate answer can be given by Intersystems only. If you take a look on the articles here, the most of them are about other lanuages, new technologies etc. but none of Cache/IRIS internals. If you look on the questions, very often they start with "I'm new to ISC technologies, need some help". Do you really expect an answer from an newbe? Or you really expect an answer from a Kubernetes, Phyton, Angular etc. developer? On the other hand, you are an Intersystems employee, so why don't ask somebody from the developer department? What about contacting WRC? I would be ashamed to ask such a question here.

I think in some cases questions are simply seeds planted for the growth of stimulating exchanges of ideas.

This is a topic I would find interesting, and I'm no newbie, nor am I an ISC employee.

If the answers to this question don't interest you, there are other questions that can use your help 😉

Don't agree. Why be ashamed of asking questions at all? :) We don't know everything. WRC doesn't know everything.

I try to ask all non-sensitive questions on community so that the info would be available publicly.
