Startup Boost

Start of changeStartup Boost is controlled by BOOST= in IEASYSxx. End of changeIf you haven’t disabled System Recovery Boost in parmlib, Startup Boost will automatically be activated during IPL, and last for 1 hour. If for some reason you want to stop the startup boost prior to the 1 hour time limit, you can issue system command START IEABE (IEA Boost End) to do so. The invoked module will likely complete before the (asynchronous) stopping of the boost completes.

During Startup Boost, WLM Routing Services will specify the correct, boosted capacity for most of the duration of the boost. A few minutes before the scheduled end of the boost, WLM will start reducing the routing weight, so that by the end of the boost, the routing weight will match the regular capacity of the image. The interval of time this decrease in routing weight happens over can be influenced via the RTBELEADTIME option in IEAOPTxx.
