This is not documented by Oracle, and is likely to change from one version to another. If you have any luck at all finding such information, it's due to a reverse engineering effort which, as you've discovered, is non-trivial. Good luck... -Mark PS Why not use log miner? -- Mark J.

I wrote a small Java program and am trying to guess the record struct reading one archived file, but I can´t figure it out. Does any one knows where can I find archived log files struct definition ? I've searched ixora.au and other sites containing Oracle internals information, but I found nothing.
