Symptoms
While using Oracles ORDCOM infrastructure installed from %ORACLE_HOME%\com\comwrap.sql on database to interact with a COM object. The COM object doesn't do anything with the database, it's just called from the database.You must have other program outside of the database that can test the COM object and that continues to work correctly.
As soon as you comment out the line (SQLNET.WALLET_OVERRIDE = TRUE) in sqlnet.ora it all works correctly, but of course you can no longer use the SEPS.
