Depending on the version LogMiner can't decode certain redo and redo block dump would help. I remember we once figured a bug when Oracle was going crazy doing branch block splits over and over again for the same index change. Another example is IOT - IIRC, LogMiner doesn't support IOT tables in 9i but not sure about 10g. On 2/9/07, Tim Gorman <tim@xxxxxxxxx> wrote:
Antonio, Why can't you use LogMiner? Does it not display what you need to see? The command ALTER SYSTEM DUMP LOGFILE '<logfile-name>' (which generates a ".trc" file in USER_DUMP_DEST) may help you gain a little more familiarity with the contents of redo log files. The contents of the ".trc" text file is quite cryptic. It won't directly show you the structure, but it may fill in the pieces of some of the things stored there for you. Hopefully, you'll learn enough to convince you that you should use LogMiner instead. Life is too short to reverse-engineer that which is readily available... Hope this helps... -Tim Antonio Belloni wrote: > I need to extract information from some archived log files but I can't use LogMiner. > > 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. > > Regards, > Antonio Belloni > > __________________________________________________ > Fale com seus amigos de graça com o novo Yahoo!
