how to view supplemental data in redo log [message #149437] Thu, 01 December 2005 15:50

After enabling supplemental logging for 3 columns (c1,c2,c3):

update t1 set c2='abc' where c1=1;
commit;
alter system dump logfile ....;

In the dumpfile, only found the before/after image of column c2, but not c1 and c3. Does anyone know how to check the supplemental data from redo log?

Thanks,
Fan Zhang
