I got feedback on oraddlscript that exceptions are raised due to incompatible versions of Oracle.DataAccess.dll. I could reproduce these exceptions on a non-development machine.![]()
After installing Oracle Data Access Components (ODAC) 11.1.0.6.21 using the install command
install.bat all c:\oracle\odp odac
the problem was solved, and I could connect to the database server.
Oracle Data Access Components (ODAC) are available for download from Oracle here.
