AUL(MyDUL) Features Overview

    AUL (MyDUL) has recovered a lot of data (including Oracle 8, 8i, 9i, 10g, 11g and ASM storage) for customers from different countries since 2005. 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 for data recovery, at worst case it can be the last solution for data recovery. We could save the world by saving the data! With AUL version 6, you can recover data files from crrupted Oracle ASM storage.

  • 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. Corrupted Oracle ASM storage, corrupted ASM disks
  • 9. Other cases that I don't list.

    AUL is not free software. By default you can only open maximum 10 data files, and data stored behind the 512MB cannot be recovered freely, unless you get the full license and register it.

    AUL for Oracle ASM (download) can be used to copy files out of Oracle ASM storage if you have probem to start up the Oracle ASM instance due to one or more disks corruptions. If your Oracle ASM storage has less than 16 disk, you can use it freely, for more disks (up to maximum 2048 disks) support, you need to contact me for official version.
