Disk space requirements on Multiplatforms

The storage requirements for IBM® MQ depend on which components you install, and how much working space you need.

Disk storage is required for the optional components you choose to install, including any prerequisite components they require. The total storage requirement also depends on the number of queues that you 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, as well as space for your own application programs.

The following tables show the approximate disk space required when you install various combinations of the product on different platforms. (Values are rounded up to the nearest 5 MB, where a MB is 1,048,576 bytes.)

Notes:
  1. A client installation includes the following components:
    • Runtime
    • Client
  2. A server installation includes the following components:
    • Runtime
    • Server
  3. A full installation includes all available components.
  4. [Windows]Not all the components listed here are installable features on Windows systems; their functionality is sometimes included in other features. See IBM MQ features for Windows systems.
[IBM i]Additional notes for IBM i:
  1. On IBM i you cannot separate the native client from the server. The server figure in the table is for 5724H72*BASE without Java, together with the English Language Load (2924). There are 22 possible unique language loads.
  2. The figure in the table is for the native client 5725A49 *BASE without Java.
  3. Java and JMS classes can be added to both server and client bindings. If you want to include these features add 110 MB.
  4. Adding samples source to either the client or server adds an extra 10 MB.
  5. Adding samples to Java and JMS classes adds an extra 5 MB.
