The diagram below represents a DAH run in non-mirror mode. The DAH distributes actions to several different IDOL Servers.
DAH system architecture (non-mirror mode)
The DAH uses either combinator or distributor virtual databases (VDBs) to distribute the actions to one or more specific IDOL Server databases. The VDBs can map to one or more IDOL Server databases, or to other virtual databases that you set up for the DAH. The way a VDB forwards actions depends on its type.
