- System resources are optimally used without being overloaded
- Workload is automatically distributed to make best use of available capacity
- Innovative algorithms eliminate delays inherent to z/OS
- Lower priority work doesn’t interfere with higher priority work
- Jobs complete sooner easing batch window constraints
A batch job can be processed by ThruPut Manager in a shorter elapsed time with Service Level Manager (SLM). It stages volumes and recalls archived datasets while the job is in the queue, manages and prioritizes job selection, eliminates execution delays, controls resources, optimizes system load and eliminates interference. These system-oriented improvements and internal efficiencies reduce the time jobs spend in the system.
With SLM, the system is effectively used without being overloaded. Otherwise unused capacity is deployed for useful work. Workload is distributed across available LPARs. Lower priority work doesn’t interfere with higher priority work and the most important jobs are given preference when the system is heavily loaded.
One might assume all of these things are already happening; however, a closer look at how batch jobs are processed by JES2 shows that is not the case. With the optimizations from ThruPut Manager with SLM, more batch work can be completed in the same batch window.
