No extensions to the VTAM generation beyond the entries necessary for the homogeneous interconnection of two z/OS systems and the extensions to the LOGON mode table and the VTAM applications described above are required when the two openFT (z/OS) systems are to be interconnected via an SNA network.
Since the interconnected systems are located in different domains, the VTAM applications used for data transfer (FJMftid, A01ftid, A02ftid, etc.) must be defined as "cross domain resources".
Example
Linking two systems openFT (z/OS):
FTZOS1 (ftid = ZOS1) and FTZOS2 (ftid = ZOS2).
The VTAM applications FJNADM, FJNNDMS0 (at least), FJAZOS1, FJDZOS1, FJMZOS1, A01ZOS1, ... , A08ZOS1 must be generated in VTAM on the z/OS computer with the FT system FTZOS1 (specify PARSESS=YES with FJMZOS1, A01ZOS1).
The VTAM applications FJNADM, FJNNDMS0 (at least), FJAZOS2, FJDZOS2, FJMZOS2, A01ZOS2, ... , A08ZOS must be generated in VTAM on the z/OS computer with the FT system FTZOS2 (specify PARSESS=YES with FJMZOS2, A01ZOS2).
The VTAM applications used for transport (FJMZOS1, A01ZOS1, ..., A08ZOS1, FJMZOS2, A01ZOS2, ... , A08ZOS2) must additionally be defined as "cross domain resources".
In addition, the LOGON mode table for openFT must be generated in both computers.
The remote FT system FTZOS2 can be entered as follows in the partner list of the FT system FTZOS1:
FTADDPTN PARTNER-NAME=FTZOS2,PARTNER-ADDRESS=FJMZOS2:SNA,IDENTIFICATION= ...If you address FTZOS2 directly in FT requests then specify FJMZOS2:SNA.
The remote FT system FTZOS1 can be entered as follows in the partner list of the FT system FTZOS2:
FTADDPTN PARTNER-NAME=FTZOS1,PARTNER-ADDRESS=FJMZOS1:SNA,IDENTIFICATION= ...If you address FTZOS1 directly in FT requests then specify FJMZOS1:SNA.
In each case, the instance ID of the partner system in the IDENTIFICATION parameter of the FTADDPTN command must be entered in the same way as it has been defined there in the FTMODOPT command.
The same example using "free VTAM names"
The following names, which apply throughout the network, should be used for the FTZOS1 FT system:
MVSMAIN (for FJMZOS1)
MVSSUB1 (for A01ZOS1)
MVSSUB2 (for A02ZOS1)
...
...
MVSSUB8 (for A08ZOS1)
The VTAM-APPL statements for these applications on the computer with the FT system FTZOS1 are as follows:
MVSMAIN APPL ACBNAME=FJMZOS1, ... MVSSUB1 APPL ACBNAME=A01ZOS1, ... MVSSUB2 APPL ACBNAME=A02ZOS1, ... ... MVSSUB8 APPL ACBNAME=A08ZOS1, ...
The remote openFT system FTZOS1 can be entered as follows in the partner list of the openFT system FTZOS2:
FTADDPTN PARTNER-NAME=FTZOS1,PARTNER-ADDRESS=MVSMAIN:SNA
