You can design the Data Archive system configuration to minimize service interruption and ensure continuous availability of the Data Vault. When you configure high availability, the archive processes can continue to run despite temporary network, hardware, or service failures.
One approach to high availability for Data Archive is to set up a failover server for the ILM Engine and the Data Vault Service. Set up a server cluster with at least two nodes, a primary server and a failover server. The primary server runs in active mode and the failover server runs in passive mode. If the primary server fails, the failover server takes over the archive and query processes.
The primary server, in active mode, processes all archive and query requests for the Data Vault. The failover server, in passive mode, does not process archive requests. However, to improve efficiency, you can install a Data Vault Service agent on the failover server so that it can also process queries sent to the Data Vault.
The primary and failover servers must have identical directory structures to make the switch from one server to another seamless. The primary and failover servers archive data to a network storage that must be accessible to both servers.
Install the Data Archive and Data Vault components on the primary and failover servers. After installation, configure the primary and failover servers to connect to the same directories for the Data Vault repository and the run-time files. Update the configuration files to use the same directories.
