Installing the WebSphere Application Server for z/OS product code

You must have a file system for storing the installed WebSphere Application Server product code. This product file system must be large enough to also contain the IBM® Business Process Manager product code that will be installed at a later stage. The default space allocations that are specified in the WebSphere Application Server Program Directory and sample jobs are considered to be sufficient because the file system can use these values to expand dynamically, provided disk space is available.

When you log in to the UNIX System Services shell to run the imcl command, you must do so with the user ID that was used to create the Installation Manager instance, or with a user ID that is connected to the default group for the user ID that created the instance. If you prefer to submit a job instead of working from the UNIX System Services shell, ensure that you run the job under this user ID.
