If you encounter the ORA-01295 error in Oracle, it means that there is an invalid option specified for the CREATE ROLLBACK SEGMENT command. This error can occur due to various reasons, such as using an unsupported option or a syntax error in the command.
To diagnose and fix the ORA-01295 error, you can follow the steps outlined below:
1. Check the CREATE ROLLBACK SEGMENT Command
First, review the CREATE ROLLBACK SEGMENT command that you are trying to execute. Ensure that the syntax is correct and that you are not using any unsupported options. The correct syntax for the CREATE ROLLBACK SEGMENT command is:
CREATE ROLLBACK SEGMENT segment_name TABLESPACE tablespace_name;
Make sure that you are not using any additional options or incorrect syntax in the command.
2. Verify the Oracle Version
Check the version of Oracle that you are using. Some options for the CREATE ROLLBACK SEGMENT command may be deprecated or no longer supported in newer versions of Oracle. Refer to the Oracle documentation for the specific version you are using to ensure that you are using valid options for the command.
3. Use the ALTER ROLLBACK SEGMENT Command
If you are encountering the ORA-01295 error when trying to create a new rollback segment, consider using the ALTER ROLLBACK SEGMENT command instead. This command allows you to modify existing rollback segments, including adding space or changing storage options.
Here is an example of how to use the ALTER ROLLBACK SEGMENT command:
ALTER ROLLBACK SEGMENT segment_name STORAGE (MAXEXTENTS unlimited);
Replace “segment_name” with the name of the rollback segment you want to modify, and adjust the options as needed.
4. Review the Oracle Alert Log
Check the Oracle alert log for any additional error messages or warnings related to the ORA-01295 error. The alert log can provide valuable information about the cause of the error and potential solutions.
5. Consult the Oracle Documentation and Support
If you are unable to resolve the ORA-01295 error on your own, refer to the Oracle documentation for the specific version you are using. Additionally, consider reaching out to Oracle support for further assistance in diagnosing and fixing the error.
By following these steps, you can diagnose and fix the ORA-01295 error in Oracle. Remember to review the CREATE ROLLBACK SEGMENT command for any syntax errors or unsupported options, verify the Oracle version for compatibility, consider using the ALTER ROLLBACK SEGMENT command, review the Oracle alert log for additional information, and consult the Oracle documentation and support for further assistance.
