These are synchronized using Oracle Recovery Manager (RMAN), which creates the initial standby database, and Oracle Active Data Guard, which synchronizes the databases when a change occurs.Īs part of the synchronization process, the primary and secondary servers exchange the following messages: Database changes-These changes are related to configuration, performance, and monitoring data.These files are synchronized once every 11 seconds. – Near real-time-For files that are updated frequently. These files are synchronized once every 500 seconds. – Batches-For files that are not updated frequently, such as license files. File changes-File changes are synchronized using the HTTPS protocol and include changes in report configurations, configuration templates, TFTP-root directory, administration settings, licensing files, the key store, and so forth.Synchronizations between the primary and secondary servers fall under two categories: This role switching between the primary and secondary servers happens within two to three minutes. When a failback is triggered, the primary server again takes over the active role.
When issues on the primary server are resolved and the server is in a running state, it remains in standby mode and begins syncing its data with the active secondary server. If the deployment is configured for automatic failover, the secondary server takes over the active role within two to three minutes after the failover. When the primary server fails (either automatically or because it is manually stopped), the secondary server takes over and manages the network while you restore access to the primary server. Upgrade from an Earlier Version of Cisco EPN ManagerĪn HA deployment consists of a primary and a secondary server with Health Monitor (HM) instances (running as application processes) on both servers.
