Installing z/OS without using an installation package

You might find that sharing system libraries or cloning an already-installed z/OS® system is faster and easier than installing z/OS with an IBM® installation package such as ServerPac. You do not have to wait for the order to be processed and the package delivered, and you do not have to use the CustomPac Installation Dialog twice. Sharing the system libraries (logical SYSRES volume) may also save DASD and support costs because you only need to install service (or additional products) once.

However, before sharing or cloning z/OS, you must have a license for each z/OS operating system that you run. If you do not have the appropriate license or licenses, you must contact IBM. Any sharing or cloning of z/OS without the appropriate licenses is not an authorized use of such programs.
