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