Installing from Pax Files Using Pax ESD or DVD › How to Install a Product Using Pax-Enhanced ESD Files › USS Environment Setup

USS Environment Setup

You need a UNIX System Services (USS) directory and a file system with adequate space to perform the following tasks:

• Receive product pax files from http://ca.com/support.
• Perform utility functions to unpack the pax file into MVS data sets that you can use to complete the product installation.

We recommend that you allocate and mount a file system that is dedicated to Pax ESD. The amount of space that you need for the file system depends on the following variables:

• The size of the pax files that you intend to download.
• Whether you plan to keep the pax files after unpacking them. We do not recommend this practice.

CA Common Services software components are packaged using four pax files. To determine which pax files to upload, see the Introduction chapter. Store each pax file you upload into its own USS directory. For example, create a directory named "base" in the USS file system that was created for ESD processing, then upload the CA Common Services base pax file to this "base" directory.

Important! Downloading pax files for the SMP/E installation as part of the Pax ESD process requires write authority to the UNIX System Services (USS) directories that are used for the Pax ESD process. In the file system that contains the Pax ESD directories, you also need free space approximately 3.5 times the pax file size to download the pax file and unpack its contents. For example, to download and unpack a 14 MB pax file, you need approximately 49 MB of free space in the file system hosting your Pax ESD directory.
