Role of SMP/E

SMP/E is a tool to install and maintain software changes to the z/OS operating system. If used properly and consistently, it acts as the official registrar of software that is currently executing in the system. It does all of the following:

• Coordinates the application of new functions, changes, and maintenance by ensuring that the proper levels of software are installed in the current environment before the changes are applied
• Invokes the proper system utility programs, such as the linkage editor or superzap, to install z/OS system components or apply maintenance to them
• Tracks the changes SMP/E installed in its own data sets
