How to Diagnose and Fix the ORA-00071 Invalid PCTINCREASE Storage Option Value Error in Oracle

by

If you encounter the ORA-00071 error in Oracle, it means that the PCTINCREASE storage option value specified for a table or index is invalid. This error can occur when creating or altering a table or index.

To diagnose and fix the ORA-00071 error, you can follow these steps:

Diagnosing the Error

1. Check the SQL statement that triggered the error to identify the table or index for which the PCTINCREASE value is specified.
2. Verify the PCTINCREASE value specified in the SQL statement and ensure that it is a valid integer between 0 and 100.
3. Review the table or index storage parameters to understand the current PCTINCREASE value and its impact on storage.

Fixing the Error

Once you have diagnosed the ORA-00071 error, you can take the following steps to fix it:

1. Update the SQL statement to specify a valid PCTINCREASE value for the table or index. For example:

   CREATE TABLE employees (
       employee_id NUMBER,
       first_name VARCHAR2(50),
       last_name VARCHAR2(50)
   )
   PCTFREE 10
   PCTUSED 40
   INITRANS 1
   MAXTRANS 255
   STORAGE (
       INITIAL 50K
       NEXT 50K
       MINEXTENTS 1
       MAXEXTENTS UNLIMITED
       PCTINCREASE 0
   );

2. If the error occurs during an ALTER TABLE or ALTER INDEX operation, modify the existing storage parameters to set a valid PCTINCREASE value. For example:

   ALTER TABLE employees STORAGE (PCTINCREASE 0);

3. If the error persists, consider reviewing the storage parameters for the table or index to ensure that they align with your storage requirements and best practices.

Additional Resources

If you need more information on Oracle storage parameters and their impact, refer to the Oracle documentation on managing storage in the database. Additionally, you can seek assistance from the Oracle community or support resources for further guidance on resolving the ORA-00071 error.

By following these steps and understanding the impact of the PCTINCREASE storage option value, you can effectively diagnose and fix the ORA-00071 error in Oracle.
