I was wondering if anyone had done any testing on the overhead of Dataguard
on the primary system?
We would like to setup dataguard for one of our systems and the business
can most likely not accept a performance degredation of the nightly batch
Now I understand that we have to turn on force logging and depending on the
amount of nologging that is happening in the batch this could be a
considerable overhead, I am just wondering besides this what the impacts
are in maximum performance and maximum availability and maximum protection
mode. I can turn on force logging without having to set up dataguard.
Let's assume for now that the network can keep up with the changes.....
