What is the method for recovering data using Oracle timestamps?
To restore timestamp data in an Oracle database, the following methods can be used:
- Oracle database offers the Flashback technology, which allows for data recovery at a specified point in time. Flashback Query can be used to retrieve data from a specific time, while Flashback Table can restore the entire table to a specific point in time.
- Backup and restore: If a backup is available, data can be restored by using the backup. Oracle Recovery Manager (RMAN) can be used for backing up and restoring databases.
- Utilize the restore to point in time feature of Oracle to revert the database to a specific point in time.
- Manual recovery: If the above methods fail to recover the data, you can also try manual recovery. This involves either stepping through transactions one by one or manually recovering corrupted data blocks.
It is important to note that when recovering data, always remember to backup current data first to prevent further loss. Additionally, choose the appropriate recovery method based on the specific situation to ensure data integrity and consistency.
