WebSphere Application Server for z/OS product code resides in MVS-partitioned product data sets and MVS file system (the product directory and its subdirectories). This topic describes the WebSphere Application Server for z/OS product directory.
Product directory
All WebSphere Application Server for z/OS product HFS files reside in the product directory and its subdirectories. The default product directory is /usr/lpp/zWebSphere/V5R1. Throughout the product and documentation, install_root is used to represent the fully-qualified path name of the WebSphere Application Server for z/OS product directory.
Locate the product directory and all of its subdirectories in the same hierarchical file system (HFS) or zSeries file system (ZFS) data set. This data set can be the same as the z/OS root or version data set, which is not recommended, or a separate data set that is used just for WebSphere Application Server for z/OS. The installation jobs and program directory assume that such a separate data set is allocated. This data set is referred to as was_hlq.SBBOHFS, where was_hlq represents the product data set name high-level qualifiers. This directory gets created during the installation process. Refer to the Program Directory, for more details.
Product directory and configuration directory
Each WebSphere Application Server for z/OS application serving environment (stand-alone application server node or Network Deployment cell) has configuration files in one or more WebSphere configuration directories. These configuration directories are created through the configuration process and contain symbolic links to files in the product directory.
