How to Diagnose and Fix the ORA-02217 Invalid Rollback Segment Name Error in Oracle

If you are encountering the ORA-02217 Invalid Rollback Segment Name error in Oracle, it means that the specified rollback segment name does not exist or is misspelled. This can occur when trying to perform a rollback operation or when a transaction is trying to use a non-existent rollback segment.

To diagnose and fix this error, follow the steps below:

Diagnosing the Error

1. Check the Rollback Segment Name: Verify the rollback segment name that is causing the error. Ensure that the name is correct and exists in the database.

2. Review the SQL Statement: If the error occurs during a specific SQL statement, review the statement to ensure that the correct rollback segment is being referenced.

3. Check Database Logs: Look for any relevant error messages or warnings in the Oracle database logs that may provide additional information about the error.

Fixing the Error

Once you have diagnosed the ORA-02217 error, you can take the appropriate steps to fix it:

1. Use a Valid Rollback Segment: If the error is caused by referencing an invalid rollback segment, update the SQL statement to use a valid rollback segment.

2. Create a New Rollback Segment: If the required rollback segment does not exist, you can create a new one using the following SQL command:

CREATE ROLLBACK SEGMENT segment_name TABLESPACE tablespace_name;

Replace “segment_name” with the desired name for the new rollback segment and “tablespace_name” with the name of the tablespace where the segment will be located.

3. Modify Rollback Segment Settings: If the error is recurring due to incorrect settings for the rollback segments, you can modify the segment settings using the ALTER ROLLBACK SEGMENT command. For example:


Replace “segment_name” with the name of the rollback segment and “size” with the desired size for the segment.

4. Check Privileges: Ensure that the user or role executing the SQL statement has the necessary privileges to access and use the rollback segments.

5. Consult Oracle Documentation: For more in-depth information on rollback segments and troubleshooting the ORA-02217 error, refer to the Oracle documentation or seek assistance from Oracle support.

By following these steps, you can diagnose and fix the ORA-02217 Invalid Rollback Segment Name error in Oracle, ensuring smooth operation of your database transactions.
