I want to corrupt a datablock(!)
Hi there,
ok, I want to do a demo of how to recover if you get a block corruption, and need to use dbms_repair & rowid scans to retrieve as much data as poss etc.
To do that I need to corrupt a single block in a datafile on unix, and this is where im stuck....
Anyone out there have any ideas how to do this. I have an idea I can use dd to copy the file out and then edit in Vi, and the use dd to put it back... or something - dunno. Any advice would be usefull...
ta lots, Bob
