Sybase Replication Products

Sybase offers product lines that specifically support replication systems with heterogeneous or non-ASE data servers, based on Sybase replication technology.

Sybase Replication products include:

Replication Server, which is the centerpiece of Sybase advanced replication technology and incorporates several features specifically to support non-ASE data servers in a Sybase replication system.
Replication Server Options that consist of a Replication Agent and either an Enterprise Connect Data Access (ECDA), or ExpressConnect for Oracle.
- Replication Agents support Replication Server by providing a way to obtain replication data from non-ASE primary databases. Replication Agents provide this support for DB2 UDB, Microsoft SQL Server, and Oracle data servers.
- ECDA database gateways support Replication Server by providing access to a variety of non-ASE databases, allowing them to function as replicate databases in a Sybase replication system.
- ExpressConnect for Oracle supports Replication Server by providing direct communication between Replication Server and Oracle database, without a need for a separate gateway server. Express Connect for Oracle is only available with Replication Server Options 15.5 or later.
Replication Agent for IBM DB2 UDB that replicates data from IBM DB2 UDB on the mainframe.

Replication Server
Replication Server can access data locally instead of from remote, centralized databases. Compared to a centralized data system, a replication system improves system performance and data availability, and reduces communication overhead.
Replication Agent
Replication Agent extends the capabilities of Replication Server by supporting non-ASE data servers as primary data servers in a Sybase replication system.
Enterprise Connect Data Access
The Enterprise Connect Data Access (ECDA) products are Open Server-based software gateways that support DB-Library™ and CT-Library application programming interfaces (APIs), and Java Database Connectivity (JDBC) and Open Database Connectivity (ODBC) protocols.
ExpressConnect for Oracle
ExpressConnect for Oracle (ECO) is a library that is loaded by Replication Server 15.5 or later for Oracle replication.
