Restore the data files to their original locations. Any existing file named 'filename' is overwritten. If recovery was successful, then open the database and reset the online logs: Disaster recovery includes the restoration and recovery of the target database after the loss of the entire target database, the recovery catalog database, all current control files, all online redo log files, and all parameter files. Use the DROP DATABASE command to delete all files associated with the database automatically. Set the DBID and start the database instance without mounting the database. Run recovery process. You can perform limited recovery of changes to a database running in NOARCHIVELOG mode by applying incremental backups. Restoring a database running in NOARCHIVELOG mode is similar to restoring a database in ARCHIVELOG mode. This article explains a method which can be used to restore oracle incremental level backup to restore rman backups on new server. To terminate the restore operation if you do not find the autobackup in the current day (or specified day), set MAXDAYS 1 on the RESTORE command. To restore the server parameter file from the control file autobackup, you must first set the DBID for your database and then use the RESTORE SPFILE FROM AUTOBACKUP command. Write a command file to perform the restore and recovery operation, and then execute the command file. Allocate a channel to the media manager and then restore the server parameter file from autobackup. A target database named trgta is on hosta and is registered in recovery catalog catdb. Thus, you must configure the media management software so that hostb is a media manager client and can read the backup sets created on hosta. This example shows how to restore the control file autobackup and recover through the latest log. Recover the data files. Connected to:Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 64bit ProductionWith the Partitioning, OLAP, Data Mining and Real Application Testing options. Enter a command such as the following to copy all data file copies to the ?/oradata/trgt directory on the new host: Enter a command such as the following to copy the autobackup backup piece to the /tmp directory on the new host: As explained in "Restoring the Server Parameter File from a Control File Autobackup", you must use the SET CONTROLFILE AUTOBACKUP FORMAT command when restoring an autobackup from a nondefault location. Restore the autobackup of the control file, optionally setting the maximum number of days backward that RMAN can search and the initial sequence number that it should use in its search for the first day. In the following example, the online redo log files have been lost, and the most recent archived redo log sequence number is 13243. Consult the media management vendor for support on this issue. To move the database to a new host by using data file copies or backup sets on disk, you must transfer the files manually to the new host. You are restoring the database to a new Linux host with the same directory structure as the old host. RMAN displays the DBID whenever you connect to a target database. Its backup information will be used while recovering database upto level of incremental level 1. At this stage, no initialization parameter file exists. If you do not care about using configured channels from your control file, then you can simply mount the database. If the database uses a recovery area, then RMAN updates a control file restored from backup by crosschecking all disk-based backups and image copies recorded in the control file. The following RMAN command creates an initialization parameter file named /tmp/initTEMP.ora on the system running the RMAN client: To restart the instance with the initialization parameter file, use the following command, again running RMAN on the same client host: This section explains what to do when all current control files are lost and you must restore a backup control file. If you know that RMAN never produces more than n autobackups each day, then you can set the RESTORE SPFILE FROM AUTOBACKUP MAXSEQ parameter to n to reduce the search time. The following example of the RUN command shows the same scenario except with new file names for the restored data files: If your goal is to perform a test run of your disaster recovery procedures, or to permanently move a database to a new host, then you can use the procedure in this section. restore controlfile from d:\oracle\backupHOQJ2VQ_1_1; 2> allocate channel c1 device type disk format D:\oracle\backup\%U; 3> backup incremental level 1 as compressed backupset database plus archivelog; restore controlfile from D:\oracle\backupROQJ719_1_1; Create a free website or blog at WordPress.com. If you have set ORACLE_SID and ORACLE_HOME, then you can use operating system authentication to connect as SYSDBA. This example assumes that RMAN is using a recovery catalog. For example: Set the database identifier for the target database with the SET DBID command. Unlike the loss of the control file, the loss of the server parameter file does not cause the instance to immediately stop. Because the autobackup uses a well-known format, RMAN can restore it even though it does not have a repository available that lists the available backups. imaginary 12c For example, enter the following command to view data file copies: For example, enter the following command to view control file backups: The piece name of the autobackup must use the %F substitution variable, so the autobackup piece name includes the string c-IIIIIIIIII-YYYYMMDD-QQ, where IIIIIIIIII stands for the DBID, YYYYMMDD is a time stamp in the Gregorian calendar of the day the backup is generated, and QQ is the sequence in hexadecimal. The following example illustrates a RUN command that restores a server parameter file from an autobackup on tape: Restart the database instance with the restored file. standby dba The DUPLICATE command assigns a new DBID to the database it creates, enabling it to be registered in the same recovery catalog as the original database. If you are using disk copies, then use the procedure in the following section. An UNTIL clause is required to specify a target time, SCN, or log sequence number for the recovery before the first SCN of the online redo logs (otherwise, RMAN issues the RMAN-6054 error). Copy the file from the old host to a new host by using an operating system utility. Similarly, RMAN attempts to find the online redo logs by using the file names listed in the control file. All rights reserved. If you do not know the DBID for your database, then see "Determining the DBID of the Database" to learn how to determine the DBID. Change), You are commenting using your Twitter account. You can query V$ views to obtain this information. connected to target database (not started)Oracle instance started. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); RESTORING INCREMENTAL RMAN BACKUP TO SAVE RESTORETIME. If you are performing a trial restore of the production database, then perform either of the following actions before restoring the database in the test environment: If the test database uses a fast recovery area that is physically different from the recovery area used by the production database, then set DB_RECOVERY_FILE_DEST in the test database instance to the new location. The recovery stops with an error if no SET UNTIL command is specified. (LogOut/ Otherwise, the recovery catalog considers the restored database as the current target database. For example, start RMAN to connect to the target database and run the @ command: Open the restored database with the RESETLOGS option. Ensure that backups used for the restore operation are accessible on the restore host. (LogOut/ For example, run SET DBID to set the DBID, then run STARTUP NOMOUNT: RMAN fails to find the server parameter file, which has not yet been restored, but starts the instance with a "dummy" file. If one is found, RMAN restores the control file to all control file locations listed in the CONTROL_FILES initialization parameter. Start RMAN and connect to a target database and recovery catalog. Afterward, use the copied recovery catalog for the test restore. MAXSEQ is set to 255 by default, and RESTORE counts backward from MAXSEQ to find the last backup of the day. It will skip files already restored. If the database instance is not started when the server parameter file is lost, and if you are not using a recovery catalog, then run the SET DBID command to set the DBID of the target database. The preceding chapters in Part V, "Diagnosing and Responding to Failures" cover the most basic recovery scenarios and are intended to be as generic as possible. To test disaster recovery, you must have a recoverable backup of the target database. Otherwise, RMAN returns an error. Sample output follows: Restore and edit the server parameter file. Because no recovery catalog is available, you cannot use preconfigured channels. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. RMAN restores the control file to whatever locations you specified in the CONTROL_FILES initialization parameter. RMAN replicates the control file to all CONTROL_FILES locations automatically. If possible, restore or re-create all relevant network files such as tnsnames.ora and listener.ora and a password file. Change). For example, enter the following command to restore the server parameter file from Oracle Secure Backup: Restart the instance with the restored server parameter file. After restoring the control file to a new location, you can then update the CONTROL_FILES initialization parameter to include the new location. If you must use a recovery catalog because the control file is not large enough to contain the RMAN repository data on all of the backups that you must restore, then use Oracle Data Pump to export the catalog and import it into a different schema or database. It will apply changes from Incremental level 1 backup. Make the source database initialization parameter file accessible on the new host. This metadata interferes with future attempts to restore and recover the primary database. If you use the procedure in this section, then the DBID for the restored database equals the DBID for the original database. To recover a NOARCHIVELOG database with incremental backups: After connecting to the target database and the recovery catalog, place the database in a mounted state: For example, you can perform incomplete recovery with the following commands: Open the database with the RESETLOGS option. You can also obtain it by inspecting saved RMAN log files, querying the catalog, or looking at the file names of control file autobackup.

The scenario assumes the following: Oracle Database is already installed on the new host. To restore the server parameter file from autobackup: If the database instance is started at the time of the loss of the server parameter file, then connect to the target database. Take another incremental level 1 backup on source DB. If an SBT channel created the control file autobackup, then allocate one or more SBT channels. If you are using tape backups, then you can restore and mount the control file, and optionally crosscheck the backups on tape, as shown in the following example: This section assumes that you have RMAN backups of the control file, but do not use a recovery catalog. If a control file autobackup is found, then RMAN restores the server parameter file from that backup to its default location.
