Creating a file system for the product code

The WebSphere® MQ product code is installed in /opt/mqm. If you cannot install the product code in the /opt/mqm file system because the file system is too small to contain the product, you can do one of the following:
  1. Create a new file system and mount it as /opt/mqm. If you choose this option, the new file system must be created and mounted before installing the product code.
  2. Create a new directory anywhere on your machine, and create a symbolic link from /opt/mqm to this new directory. For example:

      mkdir /bigdisk/mqm
      ln -s /bigdisk/mqm /opt/mqm

    If you choose this option, the new directory must be created, and the link created, before installing the product code.

The file system into which the code is installed can be a remote network device, for example, NFS. However, you must define the mount options defined on that device to allow setuid programs, including those which are setuid root, to run.
