Shipping REDO to 12c physical standby - Fastest option?

in High Availability Data Guard, Sharding and Global Data Services (MOSC) 7 commentsAnswered

Hi

We have a 12c standby database that we just configured (MAX PERFORMANCE mode)

REDO LOGS size is 2 GB and we have configured standby REDO LOGS

We were wondering if we need to wait for the archives logs to be generated on the primary and then have those shipped out to the standby and then redo applied on the standby OR we can configure it so that as soon as the transaction is committed on the primary, it gets shipped to the standby (so basically we are shipping the REDO in smaller chunks / transaction size as opposed to waiting for the LOG switch on primary and then waiting for the entire archive log to be shipped ?

Howdy, Stranger!
