Oracle archived redo logs The replication manager automatically discovers archived redo logs that are associated with Oracle tablespaces. These resources are displayed in the content pane and can be backed up and recovered using GUI actions or jobs. A complete database recovery requires the most recent backup of the datafiles, plus backups of the archived redo logs that were generated since the backing up the datafiles. • Periodic backups. Redo information is generated constantly by Oracle and it is necessary to back up archived redo logs periodically. IMPORTANT: Periodic backups is a critical aspect of backup and recovery planning. Any gap in the archived redo log sequence prevents a complete recovery. • Recovery data exposure. A recovered database can only be rolled forward to the point reflected in the most recent backup of the archived redo logs. This point determines the data exposure or maximum amount of data that might be lost in the event of a problem. • Archivelog mode. An Oracle database must be running in the archivelog mode to produce archived redo logs. • Keep or delete archived redo logs? If enough free space is available, HP recommends keeping archived redo logs between datafile backups. This can speed recovery if only the datafiles become unusable. However, once backed up, archived redo logs can be deleted to free up disk space. Oracle control files The replication manager automatically discoverscontrol files that are associated with Oracle tablespaces. These resources are displayed in the content pane. Oracle databases The replication manager automatically discovers databases on enabled hosts. These resources are displayed in the content pane and can be replicated (backed up) and restored (recovered) using GUI actions or jobs. • You can choose to back up or recover the archived redo log files that are associated with the database. See archived redo log files. • You can also select and work with individual tablespaces. See Oracle tablespaces. Oracle datafiles The replication manager automatically discoversdatafiles that make up Oracle tablespaces. These resources are displayed in the content pane and can be backed up and recovered using GUI actions or jobs. • When you select a database or tablespace to back up or recover, the replication manager backs up or recovers all the datafiles that make up the database or tablespace. • You cannot use the replication manager to back up or recover individual datafiles. License displays License information is displayed in the GUI. See the following table. If the licenses summary indicates an issue, you can use the License Events pane to identify the affected storage array. Then, you can review the affected array's license information in the Storage Properties window. 398 Oracle
