Disk space requirements on z/OS

The installation of WebSphere® Message Broker for z/OS® uses approximately 400 MB of disk space; plan on using 500 MB to allow for the component directories, and for new service fixes to be applied.

When you apply service, if you do not replace your existing installation (for example, you apply the new fix pack level alongside your existing installation), you must plan the same amount of disk space for the higher service level libraries.

If you are transferring the files by using tar to package them, you need approximately 200 MB of space for the .tar file.

You can check how much space is used and how much is free in a file system by using the OMVS command:
 df -P /pathname
100 MB is 3 276 800 512 byte sectors.

The Component directory and the Started task user ID home directory must be separate to ensure that, when dumps are taken in the Started task user ID home directory, they do not cause problems with the runtime broker that still has to write to the Component directory.
