About ExpressConnect for Oracle

ExpressConnect for Oracle (ECO) is installed automatically with SAP® Replication Server®.

ECO provides direct communication between SAP Replication Server and a replicate Oracle data server, making Oracle data easily accessible in a heterogeneous replication environment. Compared with the previous technology using a database gateway, ECO also eliminates the need for installing and setting up a separate gateway server, thereby improving performance and reducing the complexities of managing a replication system.

ExpressConnect for Oracle:

Minimizes network overhead between products
Reduces SQL parsing and datatype conversions
Takes greater advantage of “bind variable” SQL statements where it is possible to make Oracle data server processing more efficient
Uses array processing to the Oracle data server
