Plan the IBM MQ environment on z/OS
When planning your IBM MQ environment, you
must consider the resource requirements for data sets, page sets, Db2®, Coupling Facilities, and the need for logging, and
backup facilities. Use this topic to plan the environment where IBM MQ runs.
Before you plan your IBM MQ architecture, familiarize
yourself with the basic IBM MQ for z/OS® concepts, see the
topics in
IBM MQ for z/OS concepts .
Plan for your queue manager
When you are setting up a queue manager, your planning should allow for the queue manager to grow, so that the queue manager meets the needs of your enterprise.
Plan the channel initiator
The channel initiator provides communications between queue managers, and runs in its own address space.
Plan the queue sharing group (QSG)
The easiest way to implement a shared queuing environment, is to configure a queue manager, add that queue manager to a QSG, then add other queue managers to the QSG.
Plan for backup and recovery
Developing backup and recovery procedures at your site is vital to avoid costly and time-consuming losses of data. IBM MQ provides means for recovering both queues and messages to their current state after a system failure.
Plan the z/OS UNIX or UNIX System Services environment
Certain processes within the IBM MQ queue manager (MSTR) and the channel initiator (CHIN) use z/OS UNIX or UNIX System Services (USS) for their normal processing. Plan your configuration if we do not want to use the default USS configuration.
Plan for Advanced Message Security
TLS (or SSL) can be used to encrypt and protect messages flowing on a network, but this does not protect messages when they are on a queue ("at rest"). Advanced Message Security (AMS) protects the messages from the time that they are first put to a queue, until they are got, so that only the intended recipients of the message can read that message. The messages are encrypted and signed during put processing, and unprotected during get processing.
Plan for Managed File Transfer
Use this topic as guidance on how you need to set up your system to run Managed File Transfer (MFT). The queue manager needs to be a the same or higher level than the MFT code.
Plan to use the IBM MQ Console and REST API on z/OS
The IBM MQ Console and REST API are applications that run in a WebSphere Application Server Liberty (Liberty) server known as mqweb. The mqweb server runs as a started task. The MQ Console allows a web browser to be used to administer queue managers. The REST API provides a simple programmatic interface for applications to do queue manager administration, and to perform messaging.
