Host Integration Server 2006 can now connect to IBM iSeries Systems using the HPR protocol. This will allow customers to support existing SNA applications in an all TCP/IP network. With the release of IBM OS/400 version 5 release 4, Host Integration Server can now establish a connection to an iSeries system using our IP-DLC link service. On the iSeries system we had to create a Controller Description of Link type *HPRIP and with 'Remote Internet Address' set to the IP address of the Host Integration Server. Our system also had the network attribute 'APPN Node Type' set to *BEXNODE, which is branch network node. This may vary depending on your APPN topology.
