Well, that is my guess too.
When we were planning the upgrade we asked our VAR if we needed to build
a 32 bit Linux server and were told that UD 7.2 would work just fine on
64 bit Linux.
So how can I connect to a SQL Server or Oracle database from UD and read
data from it if BCI only works
You may be having an issue like I am. Universe (and probably Unidata) is a
32bit application. It will run on a 64-bit platform but will only link with
other 32bit apps. I downloaded and got running the new and free Microsoft SQL
Server odbc driver for Linux which is only supported as a 64bit
