1. Introduction
The section of the user guide explains installing Dbvisit Standby MP on AWS EC2 instances. In this guide, we focus on both primary and standby on the AWS. The setup will be a single instance primary database and a single instance standby database on Linux Platform. The data files are stored on a standard filesystem. This is just an example, and it does not limit the possibility of storing the data files on an ASM, using the Windows operating system, or using any supported Oracle platforms that are available on AWS.

The process of zero data loss role reversal is called graceful switchover. The details are discussed here . Below is the image after the switchover process is completed. The new primary is now ono.dbv-aws.envbuilder.cubicle-labs.com and the standby is rima.dbv-aws.envbuilder.cubicle-labs.com . The automated standby update is enabled in the reverse direction and rima’s is getting synced at regular intervals with archivelogs from ono.
