Crash recovery is a critical process for ensuring the stability and business continuity of a database. This process consists of returning the database to a consistent and usable state following a system crash or unexpected power outage.
When a crash occurs, the database can suffer damage and data loss. Crash recovery is therefore essential to minimize damage and restore the database to its original form.
The crash recovery process is usually automated through crash recovery software tools. These tools are able to scan the database for any problems and fix them automatically.
In general, crash recovery can be divided into three main phases: database analysis, data recovery, and transaction recovery.
In the database scan phase, the recovery software examines the database files to verify their integrity. If problems are found, the software reports them and fixes them.
In the data recovery phase, the software tries to recover all the data present in the database. This is done by restoring data from temporary storage and database backup copies. If necessary, the software can also rebuild the database tables.
Finally, in the transaction recovery phase, the software tries to recover the transactions that were in progress at the time of the crash. This is done by trying to roll back any transactions that have been recorded in temporary storage.
In conclusion, crash recovery is a crucial process to ensure the continuity of a database after an unexpected system outage. Through the use of dedicated software tools, this process can be automated and made as efficient as possible.
