    Oracle DUL is the last solution for recovery when no other method left, for example when no backup and system tablespace data file is corrupted. It's an Oracle internal use only utility which could direct read rows from data file without Oracle environment. However it's very hard to get a legal copy of this utility and you may not be able to afford the expencive cost of asking Oracle DUL recovery service. Then I decide to write a another tool to implement almost the same feature.

    AUL/MyDUL is just a personal software wrote for fun. No gurantee of 100% correction in recovery, you can only ask for it when no official way to recover your database. DBA should not take this utility into account when thinking of backup & recovery strategy. Carefully design and test your backup strategy, if you hit any problem with your database, check whether you have backup first, then contact Oracle for official support, of cause, you could take a try on AUL/MyDUL finally.

    The latest version is 3.1.9, Download now.

    AUL/MyDUL is not sellable, I could provide recovery service for you.

    The demo licence is free, but it can only open 4 files and can only read the first 512M of each openned file. If you want to remove the limit, you need to ask me for a valid licence code, the licence code can only be used once, every time you run AUL/MyDUL, it will generate a dynamic register code, licence code is calculated from the register code, so new licence code is required for every run. With the dynamic licence model, you could perform recovery locally without remote login requirement.

    I have successfully provided service for customers from China, Germany, Hongkong etc. Data volumn varis from 1G to 70G.
