Activating system software in IBM z/OS
- Static Activation — usually, this method uses SMP to link a USERMOD into the operating system. The modification is actually applied to system libraries and an IPL usually is required to activate the product. While this is a safe method of activating system software products, there are serious system maintenance drawbacks. Manual intervention is required by system programmers whenever maintenance is applied to modified CSECTS. Just scheduling the SMP work, and an IPL, often can be a problem.
- Dynamic Activation — this method requires a sophisticated activation process. SVOS is a Started Task that performs this process for BMC AMI Storage components. SVOS loads and controls the various component program modules in the z/OS operating system. This Started Task eliminates the system maintenance problems that are involved with static modification.
