Considerations for mixing interactive and batch jobs on a WAN line

When interactive jobs and large transfers are running on a communications line concurrently, you might need to change configuration parameters to work with interactive and batch jobs.

To keep interactive performance acceptable when mixing interactive and batch jobs on a wide area network (WAN) line, consider the following items:

• Use Advanced Peer-to-Peer Networking (APPN) transmission priority to prioritize the interactive jobs over that of the large transfer. This is the preferred method to transfer batch and interactive jobs.
• Change the request/response unit size to a lower value for the large transfer. This parameter setting optimizes response time at the expense of large transfer performance.
• Reduce the pacing values for the large transfer to slow it down, which allows the interactive jobs more windows for getting on the line.

The Communications Configuration manual might be a useful reference to you. It is available from the IBM® Publications Center as a printed hardcopy that you can order, in an online format that you can download at no charge, or both.
