System Recovery Boost

IBM Z System Recovery Boost Content Solution

Welcome to the IBM Z System Recovery Boost content solution, your homepage for technical resources.

With the z15 machine, you have access to System Recovery Boost, which provides capabilities to minimize the impacts of stopping and restarting z/OS. System Recovery Boost increases your processor capacity during startup and shutdown, decreasing the time it takes to process backlog. System Recovery Boost can also increase processor capacity to accelerate some sysplex recovery situations.

Big Picture: System Recovery Boost

Startup Boost

Startup boost is enabled by default and delivers extra processor capacity after an IPL to get you back up and running faster.

Recovery Process Boost

Recovery Process boost is automatically invoked to provide increased short-duration processor capacity for the acceleration of some sysplex recovery situations.

Shutdown Boost

Shutdown boost enables a faster shutdown by delivering extra processor capacity upon indication that a shutdown is in progress.


Update your automation to ensure that System Recovery Boost is optimized for your system, and take advantage of System Recovery Boost upgrade.
