Failover Management

Failover Management

In this high availability configuration, the primary server performs all archive and query processes and the failover server performs only query processes. When the primary server is down, the failover server takes over all archive and query processes.
The CRM distributes query processing between the primary server in active mode and the failover server in passive mode. If the service monitor detects that the primary server has stopped responding and cannot reestablish a connection, the CRM switches the failover server from passive to active mode.
The CRM performs the following actions:
  1. Stops the Data Vault Service agents on the failover server.
  2. Starts the ILM Engine on the failover server.
  3. Starts the Data Vault Service on the failover server.
  4. Redirects incoming HTTP requests to the IP address of the failover server.
The failover server performs all archive and query processes until the primary server is restored.
