An Overview of SAP OpenSwitch

    By: Paul Vero on Jul 31, 2014

    This article covers the basic configuration of the SAP OpenSwitch at a high level and then provides a simple example of using one SAP OpenSwitch server to connect to two different SAP ASE database servers.

    SAP OpenSwitch 15.1 is an SAP Open Server gateway application providing a transparent means for TDS clients (Open Client, ODBC, jConnect, etc) to transfer their connectivity sessions to SAP server products such as SAP ASE, SAP Open Servers or even other SAP OpenSwitches via manual intervention through administrative commands or automatically when server failures and outages occur.

    The clients require no reconnection when the switching occurs, as backend servers are started and stopped for maintenance, failover, batch processing and other tasks. This seamless connection makes for convenient availability for clients and their applications. There are various configurations that we’ll explore in this article, and in the next article (or two), we'll explore some of the possibilities for this gateway.

    If you read my previous SAP Open Server series, you’ll see how this product is an excellent example of applying the SAP Open Server API into a practical and functional component to provide all around availability.

    In this article, we’ll go over the basic configuration of the SAP OpenSwitch at a high level, touching on some of the more important aspects of the setup and demonstrating a simple example of using one SAP OpenSwitch server to connect to two different SAP ASE database servers. Connections will connect to the SAP OpenSwitch and based on the application name provided, clients connect to SAP ASE1 or ASE2. This will provide the basic understanding of the SAP OpenSwitch concept. In the next article, a more sophisticated scenario will be presented.
