I tried a simple application with a DOA Connection (TOracleSession) and a FireDAC connection (TFDCOnnection) against the same database. The application is compiled in 64bit, Oracle Client 64bit is also correctly installed. The DOA Connection works fine if the application is a dekstop exe. while it doesn't work if it is compiled as ISAPI library. FireDAC connection works fine in both situations. The class exception is EOracleError with an empty message. I also verified that DOA connection works fine in IIS 7.x (Windows7) while doesn't work in IIS 8 and above (Windows10, Windows 2012, etc...). Could you please verify it?
