JnextPlan fails to start

This error might be a symptom that your IBM Workload Scheduler network requires additional tuning because of a problem with the sizing of the pobox files. The default size of the pobox files is 10MB. You might want to increase the size according to the following criteria:

• The role (master domain manager, domain manager, or fault-tolerant agent) of the workstation in the network. Higher hierarchical roles need larger pobox files due to the larger number of events they must handle (since the total number of events that a workstation receives is proportional to the number of its connections). For a domain manager, also the number of sub domains under its control make a difference.
• The average number of jobs in the plan.
• The I/O speed of the workstation (IBM Workload Scheduler is IO- dependent).
