Hi Prem,
Yes there is a performance overhead with maximize protection. As I said
=
earlier, the LGWR process is going to ship the log changes to the =
standby database (does not wait till its applied) and hence It boils =
down to the network connectivity that exists between the primary and the =
standby database. Your overhead is proportional to the network =
bandwidth. Pls test it with a real load before you put in production.
Best Regards
Sriram Kumar

Thanks again Sriram .=20
Read in docs that " Maximum Protection " has some performance overhead .
what's ur opinion about it ? anyway , i need to test it and see whether
it
is acceptable for me .
Regards,
Prem.
