5.9.1 Considerations when using logical hosts in a non-cluster environment
When you run JP1 on multiple logical hosts, each instance of JP1 takes up system resources (including memory, disk space, CPU time, and semaphores). The system will not work properly if insufficient resources are available when multiple JP1 programs run concurrently. Estimate the system resources required according to the number of JP1 programs that will run concurrently. Alternatively, you can limit the number of concurrent JP1 programs to a number that the system can handle.
For information on estimating memory and disk space requirements, see the Release Notes.
