Oracle DUL is the last solution for recovery when no other method works, for example, when there's no backup and system tablespace datafile is corrupted. It's a tool for Oracle internal use only that can directly read rows from datafiles without an Oracle environment. However you may not be able to afford the price for Oracle DUL recovery service. So I decide to write another tool to implement almost the same features.

AUL/MyDUL is just personal software written for fun. No guarantee of 100% correction in recovery. You can only ask for it when there's no official way to recover your database. DBAs should not take this utility into account in backup & recovery strategy. Carefully design and test your backup. If you hit any problem with your database, check whether you have backup first, then contact Oracle for official support. As a last resort, try AUL/MyDUL.

AUL/MyDUL is not for sale. I can provide recovery service for you.

The demo licence is free, but it can only open 2 files and can only read the first 256M of each opened file. If you want to remove the restriction, you need to ask me for a valid licence code, which can only be used once. Every time you run AUL/MyDUL, it will generate a dynamic registration code. The licence code is calculated from the registration code, so a new licence code is required for every run. With the dynamic licence model, you can perform recovery locally without remote login.

I have successfully provided services in the past few years for customers in all continents except Africa and Antarctica, China, Germany, Hongkong, Mexico, just to name a few. Data volume varies from 1G to 70G. Every one of them was happy with my sophisticated, quality, low-price service. But for obvious reason, I'm not given permission to reveal their identity.

1. Lost system tablespace

2. System tablespace corrupted

3. Tablespace dropped but datafiles still exist

4. Table dropped if no new object has reused the space of the dropped table

5. Table truncated with reuse storage option

6. Table truncated without reuse storage option if no new object has reused the space freed by the truncation
