  Key Concepts: 
  A standby database is a type of database that is used as a backup for a primary database. It is kept in a state of readiness so that it can be quickly activated in the event of a failure or disruption of the primary database. The standby database is usually kept up-to-date with the primary database by replicating changes from the primary to the standby. 
  
  How to use it: 
  In order to use a standby database, you must first configure the primary and standby databases. This includes setting up replication between the two databases, as well as configuring the standby database to be ready for activation. Once this is done, you can then activate the standby database in the event of a failure or disruption of the primary database. 
  
  Tips & Tricks: 
  When configuring a standby database, it is important to ensure that all changes made to the primary database are replicated to the standby. This will ensure that when the standby is activated, it will be up-to-date with the primary. Additionally, it is important to regularly test and monitor both databases to ensure that they are functioning properly and that replication is working correctly.
