How to Diagnose and Fix the ORA-00202 Invalid NEXT Storage Option Value Error in Oracle

by

If you encounter the ORA-00202 error in Oracle, it means that the NEXT storage option value specified in the storage clause of a data file is invalid. This error can occur when creating or altering a tablespace, adding a data file, or resizing a data file.

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

Diagnosing the ORA-00202 Error

1. Check the storage clause of the tablespace, data file, or resize operation that triggered the error. Look for the NEXT parameter and its value.

2. Verify that the value of the NEXT parameter is a valid size for the data file. The value should be specified in bytes, kilobytes (K), megabytes (M), gigabytes (G), or terabytes (T).

3. If the value of the NEXT parameter is not in a valid format or exceeds the maximum allowable size for a data file, it will trigger the ORA-00202 error.

Fixing the ORA-00202 Error

Once you have identified the invalid NEXT storage option value, you can fix the error by adjusting the value to a valid size. Here are some examples of how to fix the error:

1. If the NEXT parameter value is not in a valid format, you can correct it by specifying the size in a valid format. For example, if the value is specified as “100M” and should be “100MB”, you can alter the storage clause to use the correct format:

   ALTER TABLESPACE example_ts
   ADD DATAFILE '/path/to/datafile.dbf' SIZE 100M
   AUTOEXTEND ON NEXT 100M;

2. If the value of the NEXT parameter exceeds the maximum allowable size for a data file, you can reduce the size to a valid value. For example, if the value is specified as “100G” and exceeds the maximum size, you can resize the data file to use a smaller NEXT value:

   ALTER DATABASE DATAFILE '/path/to/datafile.dbf' RESIZE 50G;

3. If the error occurs during the creation of a tablespace or data file, ensure that the NEXT parameter value is specified in a valid format and does not exceed the maximum allowable size for a data file.

Additional Resources

For more information on the valid formats and maximum allowable sizes for the NEXT storage option value, refer to the Oracle documentation on data file storage parameters.

In conclusion, the ORA-00202 error in Oracle indicates an invalid NEXT storage option value, which can be diagnosed by checking the storage clause of the affected tablespace or data file. Once identified, the error can be fixed by adjusting the value to a valid size. By following the steps outlined above, you can effectively diagnose and fix the ORA-00202 error in Oracle.
