Hardware and software requirements on Windows systems

Check that the server environment meets the prerequisites for installing IBM MQ for Windows and install any prerequisite software that is missing from your system from the server DVD.

Before installing IBM MQ, you must check that your system meets the hardware and software requirements. For the latest details of hardware and software requirements on all supported platforms, see System Requirements for IBM MQ.

You must also review the product readme file, which includes information about last-minute changes and known problems and workarounds. For the latest version of the product readme file, see the IBM MQ, WebSphere MQ, and MQSeries® product readmes web page.

Storage requirements for IBM MQ server

The storage requirements depend on which components you install, and how much working space you need. The storage requirements also depend on the number of queues that we use, the number and size of the messages on the queues, and whether the messages are persistent. You also require archiving capacity on disk, tape, or other media. For more information, see System Requirements for IBM MQ.

Disk storage is also required:

• Prerequisite software
• Optional software
• Your application programs

Requirements for IBM MQ Explorer

IBM MQ Explorer can be installed either as part of the product installation, or from the stand-alone IBM MQ Explorer support pack MS0T.

• The product version is available for Windows x86_64.
• The support pack version is available for Windows x86 and x86_64.

The requirements for installing IBM MQ Explorer as part of the product installation, and not as the stand-alone IBM MQ Explorer support pack MS0T, include:

• A 64-bit (x86_64) processor
• 64-bit Windows operating system

Attention: From Version 9.0.0, the 32-bit version of IBM MQ Explorer is no longer supported. For further information about Windows requirements, see IBM MQ Explorer Requirements and the following web pages:

• Windows 7 system requirements
• Windows 8 system requirements

Installation directories used for Windows operating systems

The 64-bit IBM MQ server or client, by default, installs its program directories into the 64-bit installation location: C:\Program Files\IBM\MQ. Attention: From Version 9.0.0, the 32-bit client version of IBM MQ is no longer supported.

The default data directory that is used by IBM MQ changed in Version 8.0 to C:\ProgramData\IBM\MQ. This change affects both servers, in 32 and 64 bits and clients in 64 bits. However, if there has been a previous installation of IBM MQ on the machine on which you are installing, the new installation continues to use the existing data directory location. For more information, see Program and data directory locations.

Install prerequisite software

To install the prerequisite software that is provided on the IBM MQ Server DVD (which does not include service packs or web browsers), choose one of the following options:

• Use the IBM MQ installation procedure.

  When you install using the IBM MQ Server DVD, there is a Software Prerequisites option in the IBM MQ Installation Launchpad window. We can use this option to check what prerequisite software is already installed and what is missing, and then install any missing software.

• Use Windows Explorer:
  1. Use Windows Explorer to select the Prereqs folder on the IBM MQ Server DVD.
  2. Select the folder for the software item to be installed.
  3. Start the installation program.
