In this guide, I will show you how to create a primary and standby database in the cloud. Login to your cloud account, switch to the Oracle Database Cloud Service page and create a new service. Select “Oracle Database Cloud Service” as a subscription type and click Next.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Select a database release and click Next.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Select “Enterprise Edition – Extreme Performance” as a Software Edition and click Next

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Provide the service name, SSH public key and select “Standby Database with Data Guard” option, select “High Availability” and click Next

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Review the configuration settings and click Create to create a primary and a standby database

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

After a few minutes the primary and standby database will be created successfully

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Click on the service name (srvdg) to open the home page of both databases

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Now open two different Putty executables and connect to the both machines

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Connect to the both databases and check the DB_UNIQUE_NAME parameter. PRODDB_01 is set to the primary database, PRODDB_02 for the standby database. Also check LOG_ARCHIVE_DEST_2 parameter on the primary database. As you see, archived log files are shipped to the standby database using PRODDB_02 service.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Now let’s test the functionality of the standby database. First of all, open an alert.log file of the standby database, switch the log file on the primary database and check if the log file is applied

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Now perform a switchover

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Switch the log file and see if it is applied to the new standby database

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

It worked. Now switch back

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

As you see, it’s very easy to create a database with its own standby database in the cloud!
