COM+/Microsoft Transaction Server components can access Oracle 7, Oracle 8, and Oracle 8i database servers. They can access Oracle database servers on Microsoft Windows NT and Microsoft Windows 2000, Unix, and other platforms. They can access Oracle Workgroup Servers, Oracle Enterprise Servers, and Oracle Parallel Servers.
NOTE: Due to problems with MTS/COM+ using older versions of Oracle Client, the minimum version of Oracle Client now supported is 8.1.7. Oracle Client 8.1.7 is still able to access older versions of Oracle Server, however you should contact Oracle Support for more information on this.
