Configuring using catalog aliases in z/OS

Catalog aliases can be used for configuring WebSphere Application Server for z/OS. This topic covers considerations when working with aliases.

Before you begin

About this task

A node uses either LPA/LNKLST or STEPLIB to access the traditional MVS module libraries that are part of the WebSphere Application Server for z/OS product, depending on what you specify in the z/OS Profile Management Tool. If STEPLIB is specified, STEPLIB statements are built in the JCL start procedures and a file called setupCmdLine.sh. When you apply service to a node that is using STEPLIB to access the MVS module libraries, you will need to update your JCL start procedures and setupCmdLine.sh file for the node -- unless you use catalog aliases rather than the actual data set names.

A catalog alias is a reference in the catalog that points to an actual data set. With a catalog alias, your STEPLIB can point to the alias, while the alias points off to the maintenance-specific dataset. When it comes time to switch a node over to a new level of maintenance, you can simply change the alias rather than crawling through STEPLIBs in the JCL start procedures and setupCmdLine.sh shell scripts.
