Recover a corrupted system tablespace without a backup

Question:

A client of mine has a dev database (11g on linux) that was never backed and due to a controller issue has a corrupted system tablespace.

DBV shows 100 corrupted blocks. Is there a way to open the database just long enough to  export some key tables with some important configuration data? All the tables are in one 2.1gb datafile without corrupted blocks. Are there any free/cheap unloader utilities?

 

 

Answer:

TRY ORACLE PRM-DUL http://www.parnassusdata.com/, it cost 1500 USD every Whole database whatever size.
