ABSTRACT:
A mechanism is described for transferring data between a pair of relational databases on client and server machines. A client component creates a first pipe in the client, and sends information to a server component, enabling it to create a second pipe in the server. The client component then calls the data unloading utility of the client database, causing it to start to unload the data into the first pipe. The client component then starts up a Send process in the client, which reads data from the first pipe and sends it to the server. At the server, the server component calls the loading utility of the server database, specifying the second pipe as input. As the data arrives at the server, the server component writes it into the second pipe, from where it will be read by the loading utility and written into the server database.
