Distribution

You can distribute IDOL over multiple machines, by using the Distributed Index Handler (DIH) and Distributed Action Handler (DAH). These components distribute index actions and ACI actions respectively to multiple IDOL Servers.

Distributed Index Handler

Distributed Action Handler

  • DAH Distribution Modes. Information about the basic ways to distribute actions between multiple IDOL server instances.

  • Distribution Methods. Information about distributing actions for failover and load balancing, or for distributing actions to View servers.

  • Advanced DAH Structures. Configure complex DAH structures with large distributed indexes, and multiple tiers of servers.

  • Virtual Databases. Use virtual databases to determine how to distribute actions and aggregate content.

  • Engine Management in DAH. Use the EngineManagement action to control the DAH and its child servers.
