There are five main points that have to be configured in order to configure SNA over TCP/IP. These steps must be true/configured on both the host and the target system.
1. You must have 5722SS1 option 22 "ObjectConnect" on your system.
2. Your network attributes must have "Allow AnyNet support....*YES"
3. You must have a host entry on the host system, for the target system, that has a valid IP address and route to the target system with a host name of XXX.SNA.IBM.COM (XXXX =System name of the target system)
4. You must create an APPC controller on the host and target system.
CRTCTLAPPC CTLD(XXXX) LINKTYPE(*ANYNW) RMTNETID(SYSTEMB)
RMTCPNAME(ANYNET)TEXT('AnyNet connection to system SYSTEMB')
XXXX = the controller name
RMTNETID = the remote systems name
RMTCPNAME = the remote control point name
I named mine ANYNET. This will be used on both the target and host system.
5. You have to create or modify the Remote Configuration list for QAPPNRMT.
CRTCFGL TYPE(*APPNRMT) TEXT('AnyNet TCP Connection list') <<ENTER>>
REMOTE LOCATION = the remote systems name.
REMOTE NET ID: APPN
LOCAL LOCATION: The local systems name is found by issuing a DSPNETA.
REMOTE CONTROL POINT: Is the same control point that was used when creating the controller.
CONTROL POINT NET ID: APPN
Naturally, both the host and the target systems must be configured this way. If you e-mail me, I have a nice Word document that would walk you through these steps in better detail.
