Control file Archive log If the control files are lost, they must be restored before other restore operations can be performed. Only after restoring the control files can the target database be mounted and the other restore operations started. A restore operation is typically followed by a recovery operation. 8.2 Recovery Operation Recovery is a process whereby a restored file is made available, either to the most current state or to a specific point in time. Once the data files are restored, they have to be made consistent with each other. The recover command is used to perform media recovery and to apply incremental backups. During the recovery process, RMAN automatically restores the archived redo logs as required. If RMAN has a choice between restoring incremental backup sets or applying redo logs, it always uses the incremental backups. If overlapping levels of incremental backup are available, the lowest level of incremental backup, the one covering the longest period of time, is chosen automatically. The following objects can be recovered: Individual data files One or more data files can be recovered. The target database must be started and mounted. If the target database is open, the data file must be offline. Tablespaces All data files in a tablespace can be recovered or a tablespace can be recovered to a previous point in time. The target database must be started and mounted. If the target database is open, the tablespace must be offline. The entire database The entire database can be recovered under the following circumstances: - A media failure has damaged the entire database. - The entire database must be recovered to a previous point in time. - The control files have been lost. For database recovery, the database must be started but not open. 108 Backing Up Oracle using Tivoli Storage Management
8.3 Recovery examples Archive log backup sets are restored as needed to perform a recovery. They are restored to the current archive log destination as specified in the init.ora file. In the following sections we provide some examples of recovery using RMAN. 8.3.1 Datafile recovery To test a datafile recovery with RMAN, we performed following steps: The Oracle instance paris was up and running. User user1 in a SQL*Plus session was connected to paris. We created a new table in the USERS tablespace, inserted a row, and committed the changes. In a second telnet session, the root user destroyed the file with an echo ‘oops’ > /opt/app/oracle/oradata/paris/users01.dbf User user1 inserted another row in the table and committed again. Oracle user sys connected to the database and issued an alter system checkpoint. After the checkpoint, Oracle recognized the destroyed file and took that datafile in status RECOVER. In the alertlog file of the instance, we saw following entries: Chapter 8. Recovering Oracle Databases on UNIX 109
