How to Diagnose and Fix the ORA-01294 Duplicate INITRANS Option Specification Error in Oracle

If you encounter the ORA-01294 error in Oracle, it means that there is a duplicate INITRANS option specification for a table or partition. This error can occur when attempting to create or alter a table, or when importing data into a table.

To diagnose and fix this issue, you can follow the steps and examples provided below.

Diagnosing the ORA-01294 Error

When you encounter the ORA-01294 error, Oracle will provide a specific error message that includes the table or partition causing the issue. This message will help you identify the object that needs to be fixed.

To diagnose the error, you can use the following SQL query to check the INITRANS value for the affected table or partition:

SELECT table_name, partition_name, initrans
FROM dba_tab_partitions
WHERE table_name = 'your_table_name';

Replace ‘your_table_name’ with the name of the table causing the error.

Fixing the ORA-01294 Error

Once you have identified the table or partition with the duplicate INITRANS option specification, you can fix the error by altering the table to remove the duplicate specification.

You can use the following SQL statement to alter the table and set the correct INITRANS value:

ALTER TABLE your_table_name

Replace ‘your_table_name’ with the name of the table causing the error, and ‘your_new_initrans_value’ with the desired INITRANS value.

If you are importing data into the table using a tool such as Oracle Data Pump, you can also specify the INITRANS value during the import process to ensure it is set correctly.

Additional Considerations

It’s important to note that the INITRANS value specifies the initial number of concurrent transactions that can be supported for the table or partition. When setting the INITRANS value, consider the concurrency requirements for the table and the expected workload.

If you need further assistance with diagnosing and fixing the ORA-01294 error, consult the Oracle documentation or reach out to Oracle Support for additional guidance.

By following these steps and examples, you can effectively diagnose and fix the ORA-01294 error in Oracle, ensuring the stability and performance of your database.
