What are required dependencies/dlls for Oracle ODP.net unmanaged 12.2 (Oracle.DataAccess.dll)?

Question

I am using unmanaged Oracle.DataAccess.dll having version (4.122.1.0).

However I do not want to install the Oracle client on each machine.

Can someone suggest dlls/files that I can copy with my .Net Executable, so that i do not have to install Oracle client?

Answer 1

I don't recommend to copy the DLL's manually.

Download the XCopy version you need

• ODAC122010Xcopy_x64.zip from 64-bit Oracle Data Access Components (ODAC) Downloads
• ODAC122010Xcopy_32bit.zip from 32-bit Oracle Data Access Components (ODAC) and NuGet Downloads

Then you can simply install everything from command line like

install.bat odp.net4 c:\oracle myhome true

If you still prefer to make it manually, you can read the install.bat file. It copies folder instantclient_12_2 and odp.net4 plus running a few configuration changes in GAC and Registry.

Or as an alternative use the ODP.NET Managed Driver . This requires only a single DLL Oracle.ManagedDataAccess.dll
