How can you configure ODBC Driver for OBIEE on Windows 2003 64bit Operating System?
64-bit Windows has two ODBC Data Source admin utilities. The default is found in the Windows\system32 folder, the other (same named of .exe) is found in the Windows\SysWOW64 folder; these two utilities manage distinct sets of DSNs and ODBC drivers. They use different registry sections.
The OBIEE BI Administration Tool uses the ODBC DSNs that are managed by the one in Windows\SysWOW64 folder.
Installing the Oracle 10g Client (either 32-bit or 64-bit) on a Windows x64 server creates an ODBC driver that is seen by the first one in Windows\system32, but not the second one Windows\SysWOW64 folder.
