Example: Three iSeries systems using HPR

To configure HPR, you must first configure APPN properly. To do this refer to the page, Three iSeries systems using APPN.

1. Systems A and B, shown below, must have the Allow HPR transport tower support (ALWHPRTWR) parameter set to (*YES). These systems must be V4R2 or greater.
2. The intermediate system must be V3R1 or greater, with the appropriate hardware.

In Figure 10, A and B are end nodes. The network node must configure its network attributes to reflect that it is a network node. Each system must configure the remote control-point name in the controller description that represent the adjacent system. Also, A and B must indicate in the controller description for the network node that it can be a network node. A and B must add the network node to the server list in network attributes so that the network node might act as a network server for both end nodes.
