How to Diagnose and Fix the ORA-00210 Invalid MAXEXTENTS Storage Option Value in Oracle

If you encounter the ORA-00210 error in Oracle, it means that the MAXEXTENTS storage option value for a tablespace is invalid. This error can occur when trying to create a table or index, or when altering the storage parameters of a table or index.

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

Diagnosing the ORA-00210 Error

When you encounter the ORA-00210 error, you can diagnose it by checking the storage parameters of the tablespace in question. You can use the following SQL query to do so:

SELECT tablespace_name, max_extents
FROM dba_tablespaces
WHERE tablespace_name = 'your_tablespace_name';

Replace ‘your_tablespace_name’ with the actual name of the tablespace where the error occurred. This query will show you the current MAXEXTENTS value for the tablespace.

Fixing the ORA-00210 Error

To fix the ORA-00210 error, you can adjust the MAXEXTENTS value for the tablespace. You can use the ALTER TABLESPACE statement to modify the MAXEXTENTS value:

ALTER TABLESPACE your_tablespace_name

Replace ‘your_tablespace_name’ with the actual name of the tablespace, and ‘new_value’ with the desired maximum number of extents for the tablespace.

If the MAXEXTENTS value is set to UNLIMITED, you can also consider setting a specific value to avoid the error. However, make sure to assess the storage requirements of your tablespace before doing so.

Additional Considerations

It’s important to consider the storage requirements and limitations of your tablespace when setting the MAXEXTENTS value. You can refer to the Oracle documentation for more information on tablespace storage parameters and best practices for setting MAXEXTENTS.

Additionally, you may want to review the data dictionary views related to tablespace and storage parameters in Oracle for a more in-depth understanding of the error and its resolution.

By following these steps and considering the additional considerations, you can diagnose and fix the ORA-00210 error in Oracle related to the invalid MAXEXTENTS storage option value.
