recovery_mode managed vs managed real time apply

Neo-bMar 22 2015 — edited Mar 22 2015

Hello All,

I am using Oracle 11.2.0.3

My primary database is an Oracle RAC 2 nodes database with ASM and my standby database is a single instance physical standby database on file systems.

My protection mode is MAXIMUM PERFORMANCE

What is the difference I do :

alter database recover managed standby database using current logfile disconnect; (managed real time apply)

and

alter database recover managed standby database disconnect; (managed)

Does managed real time apply have any performance impact or disadvantage?

Regards,
