rman backup and recovery

If the backup is not recoverable, then it is useless. RMAN provides a way to check database restore capabilities without having to restore the database, and provides several check options for the user. 1. Restore Preview command This command lets you see which backup set the Rman uses to perform a specific

About Recovery with a Backup Control FileIf All copies of the current control file is lost or damaged, then you must restore and mount a backup control file. You must then run the RECOVER command, even if no data files has been restored, and open the database with the Resetlogs option. If Some copies of the current control file is usable, however, then can follow

complete, you need to go to slplus again SQL> conn/as sysdba SQL> create spfile from pile; Then start the database to the mount status, An error occurs when the database is not modified due to the log file in the log file. My solution was to kill all oracle processes, Ps-ef | grep ora _ Find all the processes and then kill-9 PID Then, modify the path of the trace log file of the text parameter file to the path that you want to store on your local machine, and then start the database to the moun

1. Ranking explanation:Restore: RestoreRecover: RecoveryBackup set: similar to tablespaceBackup slice: a data file can be used across multiple backup slices, but in a backup set2. Principles:A. When a file is restored, the file cannot be used by the database instance.B. Only if the incremental level is 0 or full backup, the image copy can be restored. Other level

has been busy writing shell scripts, ignoring Oracle's basic review, just did an rman recovery, record a deeper impression. Oracle Full-Library backup is ideal for the mount, so there is no need to consider consistency issues. Just an ideal. To open the database in archive mode, complete the script as follows Log_file=/paic/hq/bk/restore/home/op11202/xionglang/in

before the database. Before creating the first consistent backup after RESETLOGS, you must not delete the consistent Database Backup created before RESETLOGS. If you have enough space, we recommend that you keep the consistent Database Backup created before RESETLOGS. Experiment ideas and steps: 1. Shut down the database for

Create the following directory on the new machine Mkdir/u02/mydb Mkdir-p/u02/mydb/oracl/{adump,bdump,cdump,dpdump,udump,pfile} Mkdir-p/u02/mydb/oradata/oracl Mkdir-p/u02/mydb/flash_recovery_area 5.
