   One common problem - does the ODBC know about the TNSNAMES?  In other   
   words, are you using the same TNSNAMES file for ODBC as you  are for   
   SQL*Plus?   
      
   Are there multiple homes?  Was the ODBC driver installed into/linked   
   with an Oracle_home whose TNSNAMES works?  Does that ODBC driver   
   undrstand the TNSNAMES_ADMIN variable?   
      
   (I haven't looked at 8.1.5 in a donkey's age.  Consider upgrading to one   
   that's supported if possible!)
