Use RMAN for recovery from different machine backups (WIN platform)

-- ========================================
-- Use RMAN for recovery from different machine backups (WIN platform)
-- ========================================

In some cases, if the database server is under disk space pressure or costs control, you need to back up the data files to a different machine, and RMAN can be used to complete this work. Based on Windows
The configuration required is relatively simple. It is only necessary to add an account and use the newly added account to start the database service and set the sharing path.
The following is a detailed description.

1. Configure the database server and backup target host
1. Account configuration (assume that host a and host B are used as the database server, and host B is used as the backup destination and can ping each other)
If host a and host B use the same administrator password, and oracleservicedbname and oracleorahome92tnslistener services on host a both use
Local System Account Login"
If host a and host B use different administrator passwords and are not considered to be the same in terms of security, you can create a new user on host a and host B separately.
Set dba_oracle on host a and set the password to ora_pwd. This user is also created on host B (the user name can be different and the password must be the same). The password is also set to ora_pwd.
. Add the user on the host to the aministrators group.
2. Set the startup account for the oracleservicedbname service and oracleorahome92tnslistener service. Enter services. MSC at run. Set this account on host
User Login, that is, using the dba_oracle just created, enter the password to start, this setting needs to be effective after restart
3. Set the shared folder on host B, such as rman_shared, and set its permissions to full control (use \ IP \ rman_shared on host a to test whether files can be written)

Ii. Check RMAN configuration and database information

RMAN> show controlfile autobackup; </P> <p> The RMAN configuration parameter is: <br/> Configure controlfile autobackup on; --> automatic backup of control files, we recommend that you enable </P> <p> RMAN> show controlfile autobackup format; </P> <p> The RMAN configuration parameter is: <br/> Configure controlfile autobackup format for device type disk to '\ 192.168.1.151 \ rman_shared \ Control <br/> _ % F '; --> control the file backup location </P> <p> RMAN> show snapshot controlfile name; </P> <p> The RMAN configuration parameter is: <br/> Configure snapshot controlfile name to 'd: \ oracle \ ora92 \ database \ sncftesthh. ora '; # default --> snapshot Control File Location </P> <p> SQL> select * from V $ version; --> database version, the current demo environment is Oracle 9i </P> <p> banner <br/> release <br/> Oracle9i Enterprise Edition Release 9.2.0.1.0-production <br/> PL/SQL release 9.2.0.1.0- production <br/> core 9.2.0.1.0 production <br/> TNS for 32-bit windows: version 9.2.0.1.0-production <br/> nlsrtl version 9.2.0.1.0-production </P> <p> SQL> show parameter db_name </P> <p> name type value <br/> ------------------------------------ ----------- --------------- <br/> db_name string testhh <br/>

3. Back up and shut down the database and delete the system01.dbf File
Use the backup script to back up the database.

D: \> RMAN target Robinson/Robin @ testhh export file = D: \ oracle \ oradata \ testhh \ backup. RMAN log = D: \ oracle \ ora <br/> data \ testhh \ backup. log <br/>

4. Restore and restore data from different hosts
1. Shut down the database

SQL> shutdown immediate; <br/> the database has been disabled. <Br/> the database has been detached. <Br/> the Oracle routine is disabled. <Br/>

2. Delete the system01.dbf data file for test recovery.

SQL> Ho del D: \ oracle \ oradata \ testhh \ system01.dbf

3. Restart the instance and receive an error message.

SQL> startup <br/> the Oracle routine has been started. </P> <p> total system global area 126950220 bytes <br/> fixed size 453452 bytes <br/> variable size 109051904 bytes <br/> database buffers 16777216 bytes <br/> redo buffers 667648 bytes <br/> the database has been loaded. <Br/> ORA-01157: unable to identify/lock data file 1-see dbwr tracking file <br/> ORA-01110: Data File 1: 'd: \ oracle \ oradata \ testhh \ system01.dbf' <br/>

4. Restore and restore with RMAN

D: \> RMAN target/--> connect to the default target database </P> <p> recovery MANAGER: Version 9.2.0.8.0-production <br/> copyright (c) 1995,200 2, oracle Corporation. all rights reserved. <br/> connect to the target database: testhh (dbid = 3955637780) </P> <p> RMAN> Restore database; --> restore the database </P> <p> Start restore from month 25 to month 11 <br/> the target database control file is being used to replace the recovery directory <br/> allocated channel: ora_disk_1 <br/> channel ora_disk_1: SID = 14 devtype = disk <br/> channel ora_disk_1: Recovering data file backup set <br/> channel ora_disk_1: specifying a data file to be restored from the backup set <br/> restoring data file 00002 to D: \ oracle \ oradata \ testhh \ undotbs01.dbf <br/> restoring data file 00003 to D: \ oracle \ oradata \ testhh \ cwmlite01.dbf <br/> restoring data file 00005 to D: \ oracle \ oradata \ testhh \ example01.dbf <br/> restoring data file 00006 to D: \ oracle \ oradata \ testhh \ indx01.dbf <br/> restoring data file 00010 to D: \ oracle \ oradata \ testhh \ xdb01.dbf <br/> channel ora_disk_1: recovered backup segment 1 <br/> segment handle = \ 192.168.1.151 \ rman_shared \ full_testhh_15mibdka_1_1 tag = full_bak Params = NULL <br/> channel ora_disk_1: recovery completed <br/> channel ora_disk_1: Recovering data file backup set <br/> channel ora_disk_1: specifying a data file to be restored from the backup set <br/> restoring data file 00001 to D: \ oracle \ oradata \ testhh \ system01.dbf <br/> restoring data file 00004 to D: \ oracle \ oradata \ testhh \ drsys01.dbf <br/> restoring data file 00007 to D: \ oracle \ oradata \ testhh \ odm01.dbf <br/> restoring data file 00008 to D: \ oracle \ oradata \ testhh \ tools01.dbf <br/> restoring data file 00009 to D: \ oracle \ oradata \ testhh \ users01.dbf <br/> channel ora_disk_1: recovered backup segment 1 <br/> segment handle = \ 192.168.1.151 \ rman_shared \ full_testhh_16mibdmb_1_1 tag = full_bak Params = NULL <br/> channel ora_disk_1: recovery completed <br/> restore completed in month 25-7-11 </P> <p> RMAN> recover database; --> restore the database </P> <p> Start recover on month 25-7-11 <br/> Use channel ora_disk_1 <br/> media recovery is starting <br/> <br/> complete the recover on month 25-7-11 </P> <p> SQL> alter database open; </P> <p> SQL> select name, open_mode from V $ database; </P> <p> name open_mode <br/> --------- ---------- <br/> testhh read write <br/>

5. Conclusion
From the above backup and recovery, there is no much difference between the use of backup and recovery from different machines and the use of local server backup and recovery operations, but the database performance is subject to a certain
. That is, the backup and recovery speed is lower than the backup and recovery speed on the local server. In a large production environment with extremely high real-time requirements, try to avoid exceptions
Backup and recovery. However, backup to recovery from different machines is still an optional solution.
