Oracle Managed DataAccess and tns access
Oracle ManagedDataAccess.dll
File Version 4.121.10
Oracle Data Provider for .NET
Our development team plans to change their Oracle Data Access method away from using the Oracle Client, but instead 'baking' (my term) the data access into the application using this DLL.
The connection string uses a service defines in tnsnames.ora.
If the hostname in the tnsnames.ora is fully qualified with the domain name, such as host_name.domain_name the connection works.
If the hostname in the tnsnames.ora is not qualified with the domain name, the connection doesn't work. It doesn't find a default domain name.
On the other hand, when I use the Oracle client and this same tnsnames.ora entry, I can connect without issue either using the domain name, or not.
