ExpressConnect for HANA DB

ExpressConnect for HANA DB (ECH) is a library that is loaded by Replication Server for HANA DB replication.

The advantages of ECH include:

It does not require a separate server process for starting, monitoring, or administering.
Server connectivity is configured with the Replication Server create connection and alter connection commands, and there is therefore no need for a separate configuration. See Replication Server Reference Manual.

A Replication Server database connection to HANA DB can be:

secure, in which the connection uses the hdbuserstore key specified in the database connection, or
standard, in which the login requires a user ID, password, and host name. A standard connection requires an entry in the interfaces file.
