I'm trying to connect via OBDC to a set of Oracle Databases that reside on the same server. I do not have any problem accessing them thru their Database SID's using the Oracle Discoverer software, however, I cannot seem to find where to specify the SID's in the MS ODBC setup. I want to have access to both dbases so I can query them using MS Access. The database SID's are ORCL and SSMA. The ORCL database existed first, and this is the only dbase I can connect to thru ODBC and MS Access. Any help is most appreciated!
