LOGMINER - any performance issue?

Hi,

Is there any performance issue to configure and switch on the 'LOGMINER' in production server? If yes why?

Regards

define "switch on".

I mean, if I will execute/run logminer in production.

of course it will affect performance, just as any other session "affects" performance. The best performing box is a box that has no users.

The question main question is "Is the need for the information out of logminer greater than the need of the population at large?". This is a question only you and your management team can answer. If you have a development box, run logminer on your development box with the production archived redo logs.
