IBM MQ Replicated Data Queue Manager Kernel Modules

Preventive Service Planning


Abstract

The Replicated Data Queue Manager (RDQM) feature of IBM MQ Advanced relies on a kernel module to provide data replication.

Content

*** Update 19 May 2021: RDQM is not currently supported on RHEL 8.4 (kernel release 4.18.0-305). IBM is evaluating the changes that are necessary to support RHEL 8.4 and will update this document as the work progresses. ***

The Replicated Data Queue Manager (RDQM) feature of IBM MQ Advanced relies on a kernel module to provide data replication.

The kernel module is only required when the RDQM component is installed.

Each IBM MQ Continuous Delivery (CD) and Long Term Support (LTS) image includes the RDQM kernel modules for each Red Hat Enterprise Linux (RHEL) kernel supported by that image.

If you upgrade to a newer RHEL kernel, then you might need to upgrade the RDQM kernel module before you are able to use RDQM with that new RHEL kernel. Failure to upgrade the RDQM kernel module, where needed, results in a failure to start the Replicated Data Queue Managers.

This document is updated at each new LTS fix pack or CD Release.

It is also updated when a new RHEL kernel is released for a version of RHEL that is supported, and indicates whether a new RDQM kernel module is required.

To get an RDQM kernel module listed on this page, either follow the Fix Central link to download, or install the relevant IBM MQ release.

RHEL Kernel Releases

Each RHEL release introduces a new kernel release, as documented at https://access.redhat.com/articles/3078

For example, RHEL 7.5 introduced kernel release 3.10.0-862.

There can be kernel updates within an RHEL release and some of these updates require an updated RDQM kernel module.

A typical RHEL kernel release has an identifier like this:

3.10.0-862.3.2

The extra digits, here “.3.2” are referred to in this document as a subrelease although that is not official terminology.

Where releases and subreleases require different RDQM kernel modules, IBM provides all of the relevant RDQM kernel modules.
