Tosska SQL Tuning Expert (TSE™) for Oracle® Free Download version has the following Limitations:
If you use TSE™ without a license, the software provides only up to 30 automatic SQL alternatives to solve most common SQL performance problems.
TSE™ however will still let you know if there are better solutions beyond the 30 alternatives if you turn the ‘full power’ option on but you just won’t be able to get the tuning details.
If you are interested to get those that are beyond the 30 alternatives, you can purchase a license from us. Please note that you are not required to re-install the product again to apply the license key. Just go to our TSE™ online store and select the appropriate option that fits your needs.
