Common topologies
Overview
The following topologies are the most common:
WebSphere Commerce is tested with all nodes in a given topology running the same operating system at the same level. This includes any patches, revisions, fixes required by WebSphere Commerce.
In the topologies, the following terms are used:
- Database node
- Only contains the database server. This node is used by WebSphere Commerce.
- Web server node
- Only contains the Web server. This node is used by WebSphere Commerce.
- WebSphere Commerce node
- Contains the WebSphere Commerce server.
The same node can also contain the database server or Web server, depending on the topology. If a node contains the WebSphere Commerce server it will be referred to as the WebSphere Commerce node.
One-node
In this topology, all WebSphere Commerce components and the supporting software are installed on a single node. This includes the database server, Web server, WebSphere Application Server, and the WebSphere Commerce server.
Two-node
A two-node configuration includes the following topologies:
- Database server is installed on one node and the remaining components are installed on a different node.
- Web server is installed on one node and the remaining components are installed on a different node.
To install a two-node topology use the custom installation option of the installation wizard.
Three-node
In a three-node topology, all WebSphere Commerce components are installed on one node, the database server is installed on a second node, and the Web server is installed on a third node. In this case, the database server is called a remote database server. The Web server is called a remote Web server.
