Configure the queue manager and channel initiator

Configure the queue manager and channel initiator

Use these topics as a step by step guide for configuring the queue manager and channel initiator.

Define the IBM MQ subsystem to z/OS
Update the subsystem name table and decide on a convention for command prefix strings.
Create procedures for the IBM MQ queue manager
Each IBM MQ subsystem needs a cataloged procedure to start the queue manager. We can create your own or use the IBM-supplied procedure library.
Create procedures for the channel initiator
For each IBM MQ subsystem, tailor a copy of CSQ4CHIN. Depending on what other products you are using, you might need to allow access to other data sets.
Define the IBM MQ subsystem to a z/OS WLM service class
To give IBM MQ appropriate performance priority in the z/OS system, you must assign the queue manager and channel initiator address spaces to an appropriate z/OS workload management (WLM) service class. If we do not do this explicitly, inappropriate defaults might apply.
Implement your ESM security controls
Implement security controls for queue managers and the channel initiator.
Update SYS1.PARMLIB members
To ensure that your changes remain in effect after an IPL, you must update some members of SYS1.PARMLIB
Customize the initialization input data sets
Make working copies of the sample initialization input data sets and tailor them to suit your system requirements.
Create the bootstrap and log data sets
Use the supplied program CSQJU003 to prepare the bootstrap data sets (BSDSs) and log data sets.
Define your page sets
Define page sets for each queue manager using one of the supplied samples.
Tailor your system parameter module
The IBM MQ system parameter module controls the logging, archiving, tracing, and connection environments that IBM MQ uses in its operation. A default module is supplied. You should create your own system parameter module as some parameters, for example data set names, are usually site specific.
Tailor the channel initiator parameters
Use ALTER QMGR to customize the channel initiator to suit your requirements.
Set up Batch, TSO, and RRS adapters
Make the adapters available to applications by adding libraries to appropriate STEPLIB concatenations. To cater for SNAP dumps issued by an adapter, allocate a CSQSNAP DDname. Consider using CSQBDEFV to improve the portability of our application programs
Set up the operations and control panels
To set up the operations and control panels you must first set up the libraries that contain the required panels, EXECs, messages, and tables. To do this, you must take into account which national language feature is to be used for the panels. When we have done this, we can optionally update the main ISPF menu for IBM MQ operations and control panels and change the function key settings.
Include the IBM MQ dump formatting member
To be able to format IBM MQ dumps using the Interactive Problem Control System (IPCS), you must update some system libraries.
Suppress information messages
Your IBM MQ system might produce a large number of information messages. We can prevent selected messages being sent to the console or to the hardcopy log.
