Oracle ODP.NET fails to upload more than 4 GB data into Oracle BLOB column

I have an .NET application using C# and ODP.NET to load the large data into Oracle BLOB column. In this application, I find that Oracle ODP.NET fails to upload more than 4 GB data into Oracle BLOB column and throws the following exception

[Oracle.DataAccess.Client.OracleException] = {"ORA-22925: operation would exceed maximum size allowed for a LOB value"}

I am running this application on Windows Vista (64-bit OS) and the database using Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production and Oracle ODP.NET version 2.111.7.0


As per ODP.NET documentation it looks like it is the limitation of ODP.NET OracleBlob class.

Howdy, Stranger!
