oracle 12c backup and recovery

When we use a database, we always want the contents of the database to be reliable and correct, but because of the calculation Failure of the machine system (including machine failure, media failure, misoperation, etc.), the database may sometimes be destroyed, How to recover data as soon as possible is a top priority. If you make a backup of your database at this time, then the number of restores It seems to be easy. This shows that a good database

Oracle Clusterware places the configuration information of the entire cluster on shared storage. The information includes the list of cluster nodes, the ing between cluster database instances and nodes, and the CRS Application resource information. That is, it is stored on the ocr disk (or ocfs file. Therefore, the importance of this configuration file is self-evident. We recommend that you back up ocr immediately between or after any operation that c

Before recovery: 1. full closed backup Do not use shutdown abort to forcibly shut down the shutdown database), implement a file-level backup, back up all Oracle related files, including Windows system files, system status and Oracle program files and data files. This cold

start point is in the data file header, and the end point is obtained in the control file. Because the archived redo log files 17 and 18 are read from the online redo log files 1 and 2. Oracle will first find online redo log files. In other words, Oracle will find the online redo log file itself during full recovery. If the file is not completely restored, we ca

Oracle backup recovery overview introduces that backup recovery is an important technology of oracle. Of course, we 'd better not use this technology, just as we do not need to go to the hospital. When you open the database,

Oracle Hot Backup refers to copying data files when they are in use. DBWR is also in progress during the replication process. Therefore, the backup may result in "inconsistent" backup: Articles: Oracle recovery Internal principles

---- When we use a database, we always hope that the content of the database is reliable and correct. However, due to computer system faults (including machine faults, media faults, and misoperations ), databases may also be damaged, so it is imperative to restore data as soon as possible. If the database is backed up at ordinary times, it is easy to restore data. This shows how important it is to back up a database. Let's take oracle7 as an example to describe how to back up and restore the dat
