WebSphere MQ CHINIT Internals [z/OS]

Project and Program: Application Architecture Development and Integration, MQ (Messaging and Queuing along with Integration Bus)

Tags: Proceedings, SHARE in Anaheim 2014, 2014

This presentation will explain some of the internal workings of the second address space, the CHINIT address space, used in the running of your WebSphere MQ subsystem on z/OS.
An assumption is made that you have a working knowledge of z/OS and WebSphere MQ on z/OS for this presentation.
We will first introduce you to the various tasks (TCBs) that run in this address space, then we will take a look at some of the system queues that are required for the CHINIT to run and then we will step through the life of a channel as it runs through these various tasks.
The aim of this session is to give you enough understanding of the internals of the address space to help you look after your CHINIT address space and keep it running smoothly.-Morag A. Hughson-IBM Corporation
