I found that it was according to sqlexecd. In the sqlhosts file on the client machine the two instances are specified with the same hostname, different servername and different service name. The sqlexecd instances on the server side are started one for each service with the TBCONFIG and INFORMIXDIR variables pointing to the appropriate file and directory for each instance, and the sqlhosts file on the server specifies the same as the client sqlhosts file. Ex: two instances, both version 5.07(for simplicity) Instance #1 uses tbconfig.instance1 and the other tbconfig.instance2 both running on machine fred: /etc/services: sqlinst1 1525/tcp # Instance one service sqlinst2 1526/tcp # Instance two service $INFORMIXDIR/etc/sqlhosts: inst1 tcp fred sqlinst1 inst2 tcp fred sqlinst2 Starting sqlexecd: . informix.environment.script TBCONFIG=tbconfig.instance1; export TBCONFIG $INFORMIXDIR/etc/sqlexecd inst1 TBCONFIG=tbconfig.instance2; export TBCONFIG $INFORMIXDIR/etc/sqlexecd inst2 Hope this helps.
