1. Introduction

This section will contain an overview of the Dbvisit Standby Agent - dbvagent.  



Dbvagent

(Dbvisit Agent)

The Dbvisit Agent is used to manage the Standby core background processes as well as managing the communication between the Dbvserver (Web-based interface) and the Dbvisit Standby core.

  • dbvagent - The main Dbvisit Agent executable, and is used to start/stop the Dbvisit Agent.

  • This agent is the link between the Central Console and the Dbvisit Standby Core which must be installed on each database server (primary and standby)

  • The Dbvisit Agent has a small footprint and is listening for secure connections on port 7891 from the Central Console

  • All communication with the Central Console is secure and encrypted

  • The Dbvisit Agent and Central console do not have to be used - some users might only want to use the Command Line Interface (Standby Core) which does not require the Central Console or the Dbvisit Agent. In this case, the Dbvisit Agent does not have to be installed or can be left shutdown.

  • The Dbvisit Agent is compulsory to run on a host to be managed by the Dbvisit Standby Central Console

  • A small repository is used to keep track of tasks being executed from the Central Console
