Installation changes for IBM MQ 9.1.0

A number of changes relating to installation have been made at IBM® MQ 9.1.0.

Optional installation of the Java Runtime Environment (JRE)

From IBM MQ 9.1.0, if you are not using Java in your messaging applications, and you are not using portions of IBM MQ that are written in Java, you have the option to not install the JRE (or to remove the JRE if it was already installed).

Attention: If you choose not to install the JRE, or to remove the JRE if it was already installed:
  • You must perform your key management by using the runmqakm command line tool rather than the strmqikm GUI tool, or the runmqckm command line tool.
  • The IBM Key Management shortcut is still installed. Clicking the shortcut has no effect. You should use the runmqakm command line tool instead.
  • Use of the runmqras command fails unless a JRE at version 7, or later, is available on the system path.

[Linux]On Linux®, You can install IBM MQ without installing the MQSeriesJRE RPM, unless you are installing the portions of the product that require the presence of the JRE, in which case the RPM prerequisites test fails. From IBM MQ 9.1, you can now also install the MQSeriesGSKit RPM without the JRE.

[Windows]On Windows, before IBM MQ 9.1, the JRE was a hidden installation feature that was always installed. From IBM MQ 9.1.0, the JRE becomes an independently installable feature. The feature can be installed or omitted, either silently or though the GUI installer, as long as you are not installing other features that require the presence of the JRE. For more information, see Install features that require the Server or JRE.

Upgrading from an earlier version of IBM MQ to IBM MQ 9.1.0 (or later) adds the separately installed JRE feature to the installed product.

For more information, see Using runmqckm, runmqakm, and strmqikm to manage digital certificates.

[Linux]

Debian installer for Linux Ubuntu

From IBM MQ 9.1.0, IBM MQ provides packages in Debian installer format (.deb files) for installation by using the dpkg command, or a higher-level installation tool, on the Linux Ubuntu distribution on all three supported architectures.

For more information, see Installing IBM MQ on Linux Ubuntu using Debian.

[Windows]

Changes to install feature names on Windows

From IBM MQ 9.1.0, there are changes to the names of some of the installable features on Windows:
  • The Java and .NET Messaging and Web Services feature is now named Extended Messaging APIs.
  • The Windows Client is now named MQI Client.

Client eImages and DVDs

From IBM MQ 9.1, separate client eImages are not available for downloading from Passport Advantage®. A separate client DVD is also not available. Instead, you can either obtain the client eImage from inside the main IBM MQ server eImage, or server DVD, which include the server and client. Alternatively, you can download the MQC91 supportpac from Fix Central (see MQC91: IBM MQ Clients).
