Arup, I kinda shook my head on that one also. So Pete, you got some inside-scoop that i've missed, i admit i've not much touched logminer in 9ir2(did alot of it and presentations back in 8i days), but have been spending my days now doing DR/RMAN implementations.

Hi Pete,

I am a little prerplexed by "selects are not recorded in redo prior to 9i ". AFAIK selects are nevere recorded in the redo, and therefore archived logs - so they are never unearthed by LogMiner, even in 9i Release2. Isn't that true?
Thanks.

Hi Robin,

LogMiner is a good tool for forensics, after the fact type work i.e to find out when your junior dba dropped that table. It shouldn't be used to do run of the mill daily work. It has a few deficiencies that are hard to work around:

o - log miner user PGA memory so cannot be used in MTS environment
o - it doesn't fully support objects
o - doesn't support chained or migrated rows (fixed in 9i, not sure

which release.)
o - doesn't support analysis of clustered tables or indexes or IOT's o - selects are not recorded in redo prior to 9i (again not sure which

release).
creating a trigger and a history table is far far more sensible and robust.
hth

kind regards

Pete
