Single-Server Configurations

PPM test and development instances are typically single-server configurations that consist of one PPM Server and one Oracle database. The single PPM Server handles the entire user load and functions as the Web server. It also houses the file system for the program code, reports, execution logs, and attachments files. The Oracle database stores all other data.

When you install PPM, you specify whether you want a server cluster configuration (required for a production instance) or a stand-alone configuration. A stand-alone PPM deployment always includes just one PPM Server installation with a single-node configuration.

You can configure a server cluster that has just one node. The difference is that you can add nodes to the "server cluster" while you cannot add nodes to a stand-alone instance.

Note: In a production environment, you must deploy a server cluster. A stand-alone configuration is adequate only in a development or testing environment.
