Disaster recovery is a backup operation that allows you to switch to an alternative BMC ProactiveNet Server (recovery BMC ProactiveNet Server) if the primary BMC ProactiveNet Server fails or is temporarily shut down for maintenance. Disaster recovery reduces the system down time and provides continued data and service availability by replicating the files between primary and recovery BMC ProactiveNet Servers. The architecture of disaster recovery system varies according to the database you use.

Disaster recovery system architecture for BMC ProactiveNet (Sybase)

The disaster recovery system consists of two BMC ProactiveNet Servers, a primary server and a recovery server. During a disaster, the DNS alias name resolves to the recovery BMC ProactiveNet Server so that data and service availability are continued.

Disaster recovery system architecture for BMC ProactiveNet (Oracle)

The disaster recovery system consists of two BMC ProactiveNet Servers, a primary server and a recovery server. They are connected to separate database servers that run Oracle Database. During a disaster, the DNS alias name resolves to the recovery BMC ProactiveNet Server so that data and service availability are continued.

Recommendation

On a high availability setup, you must enable disaster recovery as a postinstall configuration setup because the disaster recovery does not get enabled during installation even if you enable the Disaster Recovery Mode - Enable option.
