![Create RAC Standby Database Using DBCA [19c Version]](https://project42.site/wp-content/uploads/2020/08/Standby_DBCA_RAC-360x240.png)
DBCA evolves the same way than most Oracle Components, and since 12.2 version, you can create Standby Databases directly using DBCA.

Since 12.2, Managed Recovery Process (MRP) can be started on multiple instances, making Standby recovery much faster and making easier for the system to be kept on Sync with your Primary Database (Found thanks to this old post: http://jeyaseelan-m.blogspot.com/2018/05/mira-multi-instance-redo-apply-12cr2.html) This new feature is called MIRA (more info in following PDF https://www.oracle.com/technetwork/database/availability/redo-apply-2745943.pdf) The process to enable... » read more
