Example of a complete Oracle RMAN backup and recovery

Source: Internet
Author: User
The target database version is oracle8.1.7, the directory database version is oracle9.2.0, and all data files (including control files and On-line log files) are lost. Examples of using RMAN for backup and recovery are as follows:

Tutorial steps:

1. Create a tablespace in the directory database to restore the directory:

SQL> Create tablespace rmants datafile '/opt/Oracle/DB02/oradata/orcl/rmants. dbf' size 100 m autoextend on next 1 m maxsize unlimited;

Tablespace created.

2. Create and authorize the RMAN user in the directory database:

SQL> create user RMAN identified by RMAN default tablespace rmants temporary tablespace temp quota unlimited on rmants;

User Created.

SQL> grant recovery_catalog_owner to RMAN;

Grant succeeded.

3. Create a recovery directory in the directory database:

$ RMAN catalog RMAN/RMAN

Recovery MANAGER: Release 9.2.0.4.0-64bit Production

Copyright (c) 1995,200 2, Oracle Corporation. All rights reserved.

Connected to recovery Catalog Database
Recovery catalog Is Not Installed

RMAN> Create catalog tablespace rmants;
Recovery catalog created

4. register the target database to the recovery directory
The service name used by my target database is rcat.
$ RMAN target/(execute this command on the target database and connect to the target database with RMAN first)

Recovery MANAGER: Release 8.1.7.3.0-Production

RMAN-06005: connected to target database: orcl (dbid = 1000277484)

RMAN> connect catrman RMAN/RMAN @ rcat (connect to the catalog directory database)

RMAN-06008: connected to recovery Catalog Database

RMAN> Register database; (register the target database on the catalog directory database)

RMAN-03022: compiling command: Register
RMAN-03023: Executing command: Register
The RMAN-08006: Database registered in recovery catalog
RMAN-03023: Executing command: Full Resync
RMAN-08002: Starting full Resync of recovery catalog
RMAN-08004: Full Resync complete

The preparation is complete. Now we use RMAN for backup and recovery.

5. Complete RMAN backup:
RMAN> RUN

Some error messages are found. The cause of analysis is mainly because arch_1_5.arc archiving logs are not found. At this time, you can only manually execute alter database open resetlogs to open the database:
SQL> alter database open resetlogs;

Database altered.

Note: When the database is opened, some data may be lost, mainly the data in the current redolog. Therefore, use the current redolog to restore the last log file in the previous step.
