As Jim mentioned there is the DUL (Data Unloader ) tool that Oracle consulting can use for you. The normal stated accuracy is 99% depending on your system. It never understood how to follow chained rows. You are lucky to be on 8.1.6 as they never updated the tool to 9i/10g according to the developer, ( a project sometime in the future for him). Give us so more details about what exactly happened and what you have of your database, then we may be able to help you. -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of jost@xxxxxxxxxxxx Sent: Monday, September 05, 2005 9:00 AM To: ORACLE-L@xxxxxxxxxxxxx Subject: Reading corrupted Datafiles offline Hi list, assuming the following scenario: No working Backup because of several reasons. Not all datafiles of the database Corrupt blocks in the datafiles we have So, as far as i know, there no way to restore the Database in any conventional way. My question is, is there any oficiall or unoficiall way to read the data from the datafiles direct? System ist Linux and Oracle 8.1.6(!) We need not the total whole off the data but some important tables from one special tablespace. I am aware of bad luck with the location of the corrupted blocks, but i will give them a try ;-) If you need more Information feel free to ask.
