Job Management Partner 1/Automatic Job Management System 3 Administration Guide
If you run JP1/AJS3 concurrently on multiple hosts (a physical host and one or more logical hosts), consider the following points and estimate the amount of resources required in the entire system, and then allocate sufficient resources to each instance of JP1/AJS3. If sufficient resources are not allocated, programs might not operate correctly or processing might be delayed due to degraded performance.
- Because each JP1/AJS3 program running on each host uses system resources (memory, disks, CPU, communication ports, processes, and semaphores), make sure that the amount of the resources that will be in the entire system does not exceed the limit.
- Starting just JP1/AJS3 consumes a fixed amount of system resources that creates a load on the entire system. Accordingly, processing does not improve proportionately to the number of JP1/AJS3 programs started. Adjust the number of JP1/AJS3 programs that can start concurrently based on the system performance considerations.
- Make sure that the total number of JP1 events that can occur or jobs that can be executed is within the range of operation permitted for the system containing the physical host and logical hosts.
For details about how to estimate the resource usage on a logical host, see 3.2 Estimating system performance in the Job Management Partner 1/Automatic Job Management System 3 System Design (Configuration) Guide, and then estimate those system resources whose setting values change according to the number of logical hosts.
