Introduction to the Oracle Recovery Manager (RMAN)

Siemens Digital Industries Software recommends the Oracle Recovery Manager (RMAN) product be used with the Teamcenter integrated backup application. RMAN is an Oracle utility that backs up, restores, and recovers database files. This is a feature of the Oracle database server and does not require separate installation. Recovery Manager uses database server sessions to perform backup and recovery operations. It stores metadata about its operations in the control file of the target database, and optionally, in a recovery catalog schema in an Oracle database. You can invoke RMAN as a command line executable from the operating system prompt or use some RMAN features through the Enterprise Manager interface. The features of RMAN are available using the Oracle Backup Manager interface. This is a command line interface, similar to SQL*DBA. It provides a powerful operating-system- independent scripting language and works in interactive or batch mode. The RMAN environment consists of the utilities and databases that play roles in a backup and recovery strategy. A typical RMAN setup utilizes the following components: RMAN executable Target database Recovery catalog database Media management software Of these components, only the RMAN executable and target database are required. RMAN automatically stores its metadata in the target database control file, so the recovery catalog database is optional. Siemens Digital Industries Software recommends maintaining a recovery catalog. If you create a catalog on a separate machine and the production machine fails completely, you have all the restore and recovery information you need in the catalog. When configuring backup and recovery, you must specify all the following items to ensure a complete recovery: The database (such as Oracle and MS SQL). All database volumes. The TC_DATA directory. The TC_ROOT\install directory, which stores configuration data. The TC_ROOT\bmide directory (if the Business Modeler IDE is installed). This directory can contain database templates and custom templates under project folders. All local Business Modeler IDE project folders, including project folders within source control management (SCM) systems. You can hot back up the database and volumes. You must cold back up the remaining items.
