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
