Recover Deleted Oracle Data

To recover mistakenly deleted Oracle data, you can try the following methods:

1. Utilize backup recovery: If you have recent backup files, you can use Oracle’s recovery tool to restore accidentally deleted data. You can use the RMAN tool to restore the database to a specific point in time from the backup file, or import the backup file into a new database to recover the data.
2. Flashback technology is available in Oracle to assist in quickly recovering accidentally deleted data. You can use the FLASHBACK TABLE statement to restore deleted data in a table, or use the FLASHBACK QUERY statement to view data in a table at a specific point in time.
3. Utilizing Undo Tablespace: In Oracle, the Undo tablespace enables you to recover accidentally deleted data. By querying the information in the Undo tablespace, you can retrieve deleted data and then reinsert it into the database.
4. Using third-party tools: If the above methods are unsuccessful in recovering your data, you may want to consider using some third-party tools to restore accidentally deleted Oracle data. These tools are typically able to scan database files and attempt to recover the deleted data.

It is recommended to make a full backup before recovering data using any method to prevent further data loss in case of problems during the data recovery process.
