Oracle Database Recovery: Rebuild & Restore

Rebuilding and recovering databases in Oracle typically involves the following steps:

1. Backup the database: Make sure to backup the database before performing any rebuilding and restoring processes to prevent data loss.
2. Rebuild the database: If the database is damaged or encountering issues, you can use tools and commands provided by Oracle to rebuild the database. This can be done using the Database Configuration Assistant (DBCA) or by manually creating the database using SQL commands.
3. Database Recovery: In case of database failure or data loss, you can restore the database using backup files. The Recovery Manager (RMAN) tool can be used to recover the database.
4. Database Testing: After rebuilding and restoring the database, it is essential to conduct tests to ensure that the database is functioning properly and data integrity is maintained.

In general, rebuilding and recovering a database is a complex and tedious process. It is recommended to carefully read the official Oracle documentation and proceed with the operation based on specific circumstances.
