Creating a Physical Standby database using RMAN restore database from service ( Doc ID 2283978.1 )
I have a Exadata RAC environment. Primary DB is (50 TB+) and I have to create a DR/Standby DB for it. Primary has 7 DB nodes. DR has 2 DB nodes. Average daily REDO logs are 5 TB. I am using HIGH redundancy.
I am following Oracle's Doc ID 2283978.1. According to it : Primary DB online redo logs :
are sized so they do not switch more than 6 times per hour at peak redo generation (this can significantly impact redo apply in Data Guard)
reside on the DATA disk group
are multiplexed on NORMAL redundancy disk groups (HIGH redundancy disk groups are not multiplexed)
have a minimum of 3 groups for each thread of a RAC database
