# ActivateIRSMode

Use Instant Response Server mode. If you are running the Distributed Action Handler in Non-mirror mode and are using Distributor VDBs that are mapped to a normal child server and an IRS (Instant Response Server), you can type `true` to operate the Distributed Action Handler in IRS mode. This option instructs the Distributed Action Handler to forward all `Query`, `Suggest` and `SuggestOnText` actions to the normal child server, unless they include the parameter IRS set to `true`, in which case they are forwarded to the child IRS.

NOTE: You must identify IRS children in the configuration file `[Engines]` section by setting an appropriate `N` for them.
