AUL (MyDUL) has recovered a lot of data for global customers. As it can read the rows out from data files without Oracle environment just as Oracle DUL can do, we can use it in the following case when you have no valid backup (Sometime customer have backup but it's incomplete or corrupted, and cannot be used for data recovery) available, sometime it is the last solution for data recovery.
- 1. Lost system tablespace
- 2. System tablespace corrupted
- 3. Tablespace dropped but data files still exist
- 4. Table dropped if no new object has reused the freed space
- 5. Table truncated with reuse storage option
- 6. Table truncated, but no new object has reused the freed space
- 7. Missing some data files for a given tablespace
- 8. Other cases that I don't list.
