Metalink doc ID 828274.1 might be worth looking at for you but the standard answer of "it depends" seems relevant here. What is your standby DB going to be used for...Reporting? Failover? It is important to you that transactions are applied as quickly as possible to the standby?

Subject: Real time apply feature in 10.2
Hi All,
I am a newbie to oracle dataguard.
I had one doubt regarding real time apply feature in 10.2
Using Real-Time Apply to Apply Redo Data in a physical standby in 10.2 has the following benefits according to the oracle 10.2 dataguard documentation.
"If the real-time apply feature is enabled, log apply services can apply
redo data as it is received, without waiting for the current standby redo
log file to be archived. This results in faster switchover and failover
times because the standby redo log files have been applied already to the
standby database by the time the failover or switchover begins."
are there any advantages other than the above to enable the real time apply
feature in 10.2 for a physical standby.
what is the recommended way (enable or disable real time apply) and why is
that so?
Please advise.
Regards,
Satvik
