Set the backup set size ( all results of a backup are one backup set, pay attention to the backup set size ) backup database maxsetsize = 100m tag = 'datafile1'; Note: maxsetsize limits the size of the backup set. All Link Inmportantes http://basesdedatosues.blogspot.com/2010/07/creando-manualmente-un-data-guard-en.html CONFIGURACION DATAGUARD PARA D 1)Query-select 2)DDL - Data Definition Language: statements used to define the database structure or schema. To view backups of archivelog between two sequences: Use the SUMMARY directive to view only the backupsets affected: To view backups completed before a specific date: To list archivelogs recognized by the controlfile: Displaying Index Code From time to time youll need to drop an index. 4.2.2 Backup optimization backup optimization configure backup optimization on; configure backup optimization off; configure backup optimization clear; the default value is closed , if open, rman will perform an optimized algorithm for backup data files and archives and other files. RMAN-06183: datafile or datafile copy larger than MAXSETSIZE: file # 1 /data/oradata/system01.dbf 3. The third and fourth: NONE can invalidate the backup retention strategy.

List backup summary; --Overview available backups B means backup A means Archivelog, F means full backup, 0,1,2 means incremental level backup A means available AVALIABLE, X means EXPIRED This command can derive many similar commands, For example, list backup of database summary list backup of archivelog all summary list backup of tablespace users summary; list backup of datafile n, n, n summary These commands allow us to have an overall and intuitive understanding of the existing backup files. Based on Back up data files at the second backup time 1> Only back up the new data files added backup database not backed up; 2> Back up the data files that have not been backed up within a limited time period backup database not backed up since time = 'sysdate-2'; 10.

Therefore, it must be larger than the total data file size of the database, otherwise an error will be reported.

Set backup flag backup database tag = 'full_bak1'; Note: Each tag must be unique, the same tag can be used for multiple backups to restore only the latest backup. Check database errors backup validate database; use RMAN to scan the database for physical / logical errors, and do not perform actual backups. 2. Any backups that exceed the latest 5 copies will be marked as redundancy. configrue snapshot controlfile name clear; Forces the database to automatically back up the control file after backing up files or executing commands that change the structure of the database . all results of a backup are one backup set, pay attention to the backup set size, Skip offline, inaccessible or read-only files, Based on Back up data files at the second backup time, Check logical errors during backup operation, Display the current configuration information, generally safest way is to use the second retention strategy. This snapshot file is generated during the backup and is used to control the read consistency of the file. dbf and users01.dbf. Backup common command summary notes 1. 2.3.report unrecoverable; report unrecoverable data files in the current database (that is, there is no backup of this data file, or the backup of this data file has expired), 2.4.report need backup; report the data files that need to be backed up (according to different conditions) report need backup days = 3; -data files that have not been backed up in the last three days (if there is a problem, these data files will need to be archived in the last 3 days The log can be restored) report need backup incremental = 3;-How many incremental backup files are needed to restore the data files. 1.2 Query non-default values in RMAN settings : SQL> select name, value from v $ rman_configuration ; 4.2 commonly used configure options 4.2.1 preservation strategies (Retention Policy) configure Retention Policy to Recovery window of 7 Days; configure Redundancy Retention Policy to 5; configure the Clear Retention Policy; CONFIGURE RETENTION POLICY TO NONE; The first type of recover window is to keep all sufficient backups, which can restore the database system to any time within the last seven days. Force backup backup database force; 9. This snapshot file is generated during the backup and is used to control the read consistency of the file. This command is very useful for read-only table spaces. Its default value is 1 copy. Backup control file backup database device type disk includ current controlfile; Fourth, configure common commands summary memo. The generally safest way is to use the second retention strategy. 3. Each backup of Oracle can have multiple identical copies. 4.3.8 backup set size maxsetsize configure maxsetsize to 1G | 1000M | 1000000K | unlimited; configure maxsetsize clear; 4.3.9 Other options auxiliary CONFIGURE AUXNAME FOR DATAFILE 1 TO '/oracle/auxfiles/aux_1.f'; CONFIGURE AUXNAME FOR DATAFILE 2 the TO '/oracle/auxfiles/aux_2.f'; the CONFIGURE DATAFILE AUXNAME the FOR. This prevents the control file and catalog from being lost, and the control file can still be recovered. and text available under

1.1. Set the backup slice size ( tape or file system limit ) run { allocate channel c1 type disk maxpicecsize 100m format '/ data / backup / full_0_% U_% T '; backup database tag =' full_0 '; release channel c1; You can also set the backup slice size in configure.

Switching Datafile Filenames After a Restore: Transporting Tablespaces on the Same OS Platform, Tuning RMAN Backup Performance: Procedure. List the database currently backed up by RMAN : RMAN> list incarnation; summary query: --If there are many backup files, use these two list commands to get an overall understanding of the backup files. Any database backup older than the last seven days will be marked as obsolete. The second type of redundancy is to maintain the latest 5 database backups that can be restored. 3 the TO '/oracle/auxfiles/aux_3.f'; the CONFIGURE DATAFILE AUXNAME the FOR. is the storage path and file name of the snapshot file of the configuration control file. This command is very useful for read-only table spaces. 4.3.7 exclude option the exclude the configure the exclude for TABLESPACE 'the Users'; configrue the exclude the Clear; This command is used to not back up the specified table space to the backup set. Generate backup copies backup database copies = 2; 12. Check logical errors during backup operation backup check logical database; backup validate check logical database; 11.
