This answer to a similar question concerning Oracle 8i was posted to the TestStand ListServ:
I have used Oracle 7 and 8.0.5 but not 8i. If you are using the Microsoft Oracle driver, I would not recommend it. If you are using an Oracle ODBC driver, I would recommend that you check their web site to see if you have the latest Oracle ODBC driver especially if you are using the default shipped with 8i. In addition, I have had better performance and less errors with the Oracle OLE-DB Provider that now comes with Oracle Client and it is available from their web site. The next version of TestStand will recommend to use the Oracle provider instead of the ODBC driver because of some problem that we saw with the ODBC driver that did not occur with the provider.
