If Bull DPX/20 SNA/20 Server is installed prior to installing DB2 Connect for AIX, DB2 Connect for AIX uses Bull SNA. Otherwise, you need to configure DB2 Connect to work with IBM SNA Server for AIX.
To determine if Bull SNA is installed on your AIX 4.1.4 (or later) system, issue the command:
lslpp -l express.exsrv+dsk
If Bull SNA is installed, you will see output similar to the following:
Fileset Level State Description
----------------------------------------------------------------------
Path: /usr/lib/objrepos
express.exsrv+dsk 2.1.3.0 COMMITTED EXPRESS SNA Server and
Integrated Desktop
If you install Bull SNA after installing DB2 Connect for AIX and you want DB2 Connect for AIX to use Bull SNA instead of IBM SNA Server for AIX, log on as root and run the command:
/usr/lpp/db2_05_00/cfg/db2cfgos
