Create a Database Standby (Data Guard) on OCI Oracle Cloud for a DB System Database

Create a Database Standby (Data Guard)  on OCI Oracle Cloud for a DB System Database


In one of my previous post I have created a 12c DB System on Oracle Cloud OCI.

Now for that database I am going to create a Dataguard for that database. In OCI we need to have an Enterprise version to create a data guard.

Steps:

1) Login to OCI console and go to Database Services. Select the Database and click on Data Guard Association.




2) But Wait ....!!! Before creating the dataguard, let's create a database image. Go to Database details and follow below screenshots. This image will be needed while creating the dataguard






It takes some time to create the image.
Validate that the database image is created.





3) Now we will create DG. Go to navigation as given in point 1 and follow as below. Give the same shape as primary database(not mandatory) and choose the image created in step 2.










Click Next







Click on Enable Data Guard

It will take time to complete. Approx. 1 hr 25 mins 
Process is running to provision the DG.





My Standby is created.




Lets connect to my Primary and Standby to verify

The standby host will also use same ssh keys as per the primary.
