Sorry, if this is already answered. >> but, back to my original question, am I correct that "ROLLBACK=1" indicates that this transaction was applied to rollback a row? Yes. That's correct. But, there may be more than one redo record per row, for dependent objects (such as index) etc. ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Ahbaid Gaffoor Sent: Sunday, December 09, 2007 2:00 PM To: nigel_cl_thomas@xxxxxxxxx Cc: oracle-l Subject: Re: Logminer Question Hello Nigel, there are no deferred constraints, actually the design is so bad that there are very few constraints. I'm beginning to want to take the app from the developer and start going through it with a fine tooth comb. This is perhaps the best approach to see what's going wrong. The problem I am faced with is the developer is claiming "Oracle is doing something" :) I think I need to tear the app apart... but, back to my original question, am I correct that "ROLLBACK=1" indicates that this transaction was applied to rollback a row? Also, how do you order entries in V$LOGMNR_CONTENTS if they have the same SCN and TIMESTAMP? many thanks Ahbaid
