Oracle DUL & Desperation: The Trials and Tribulations of Corruption

What tools exist for DUL?
As mentioned before, there are very few utilities available for unloading Oracle data files. If you should run into a situation where you need this type of utility or service, I’ve compiled a comprehensive list below:

• Bernard’s Data UnLoader
  Oracle’s official DUL utility was initially written by Bernard van Duijnen as a standalone C application for Oracle Support in the Netherlands. DUL services from Oracle are offered only as a consulting-based engagement and are rumored to be quite expensive.

• PRM-DUL by ParnassuData

• Download :   http://zcdn.parnassusdata.com/DUL5108.zip  , ParnassusData provide PRM-DUL as a product , they also provide Data Recovery/Rescue Service. PRM-DUL is written by Java, support mos of OS platforms .

• Oracle Salvage
  Oracle Salvage is a SQLite-based data unloader written in C by former Oracle kernel developer Scott Martin of Terlingua Software. It is offered as a product.

• OracleRecovery
  A MSVC++-based DUL utility from OfficeRecovery. It is offered only as a product.

• Recovery for Oracle
  Recovery for Oracle is a Delphi-based DUL utility offered as both a service and a product from a guy in Poland.

• WisdomForce FastReader for Oracle
  Another utility capable of performing parallel and selective data unload from Oracle.

• MyDUL
  Different from AUL, MyDUL is a non-commercial utility written by Jerry Sun. I am not sure whether it is still publicly available.

• CLOUT
  Clever Little Oracle Unloading Tool, my own proof-of-concept DUL utility, is not commercially available.

• K2Tor Pro
  Available in both educational and real-life versions, K2Tor is able to describe the data file structures as well as perform data unloading.

• FlashUnload
  Currently listed as an empty SourceForge project (with screenshots), I’m currently verifying that this utility was written by ex-Oracle RAC performance guru Stefan Roesch.
