Communicating between Databases and GLS

I want to communicate from Informix Online 7.20.UC2 database to my SAP R/3 (release 2.2f) Informix Online 6.00.USAP2 Database. The 7.20.UC2 database is on a Sun box running Solaris 2.4 The 6.00.USAP2 database is on a RM600 running Sinix 5.42 When I set DBNLS=2, I can connect to my 6.00.USAP2 database with dbaccess from my 7.20.UC2 database, so I figure that my sqlhosts is set up correctly. What I am unable to do is query the 6.00.USAP2 database from within a database on my 7.20.UC2 machine. If I try, dbaccess says: 7203: DBNLS is not set or LC_COLLATE must be 'C'. 117: ISAM error: bad custom collating sequence.When I set: DBNLS=1 LC_COLLATE=C It doesn't allow me to run dbaccess until I set: DB_LOCALE=en_US.819Then it gives me the same message as before? My 6.00.USAP2 database environment is as follows: DBNLS=1 LC_COLLATE=C DBLANG=msg LC_CTYPE=De_DE.88591 I have tried various combinations of LC_CTYPE and LANG on my 7.20.UC2 database with no success. Any help would be appreciated. Regards Konrad Smuts
