Changing the REDO LOG and STANDBY REDO LOG size on Standby database only

in High Availability Data Guard, Sharding and Global Data Services (MOSC) 8 commentsAnswered

Hi

We have a (19c) 2 node RAC primary database with a physical standby database (single instance / non RAC) that we have inherited. We noticed that the size of the REDO logs and standby redo logs on the primary database is different as compared to standby database

For example, here is primary database redo and standby redo logs


And Here is the information from STANDBY database

So as you can see that redo log size and standby redo log size on primary is 2048M

Whereas on standby database it is 1024M

We were wondering what would be the correct method / process to change it so that the STANDBY database REDO and STANDBY REDO logs are sized same as primary production database

Howdy, Stranger!
