4.5.5 WAS for z/OS

The Update Installer is only used when upgrading WAS for z/Linux but not for WAS for z/OS®. WebSphere on Z/OS is installed via a SMP/E (System Modification Program Extended) process. SMP/E is an element of z/OS that is used to install most software products in z/OS and OS/390® systems and subsystems. It controls these changes at the element level by: - Select the proper levels of elements to be installed from a large number of potential changes.

- Calling system utility programs to install the changes.

- Keeping records of the installed changes.

SMP/E is an integral part of the installation, service, and maintenance processes for z/OS and OS/390 software products and product packages. See the Applying product maintenance article in the WebSphere for z/OS InfoCenter for additional information. This article is available at:
