16.1 Understanding Oracle Fusion Middleware Backup and Recovery

An Oracle Fusion Middleware environment can consist of different components and configurations. A typical Oracle Fusion Middleware environment contains an Oracle WebLogic Server domain with Java components, such as Oracle SOA Suite, and a WebLogic Server domain with Identity Management components. It can also include Oracle instances containing system components such as Oracle HTTP Server, Oracle Web Cache, Oracle Internet Directory, and Oracle Virtual Directory. The installations of an Oracle Fusion Middleware environment are interdependent in that they contain configuration information, applications, and data that are kept in synchronization. For example, when you perform a configuration change, information in configuration files is updated. When you deploy an application, you might deploy it to all Managed Servers in a domain or cluster. It is, therefore, important to consider your entire Oracle Fusion Middleware environment when performing backup and recovery. You should back up your entire Oracle Fusion Middleware environment at once, then periodically. If a loss occurs, you can restore your environment to a consistent state. The following topics describe concepts that are important to understanding backup and recovery: ■ Impact of Administration Server Failure ■ Managed Server Independence MSI Mode ■ Configuration Changes in Managed Servers
