Distributed Index Handler 12.12

# Disable the IDOL Servers

You can use the `EngineManagement` action to dynamically take child servers offline (without restarting the DIH). Send the `EngineManagement` action with the `EngineAction` parameter set to `Edit` and the `Disabled` parameter set to `True` to temporarily disable a child server of the DIH:

    http://DIHhost:ACIPort/action=EngineManagement&EngineAction=Edit&ID=1&Disabled=True

This action disables the server with ID `1`. When a child server is disabled, the DIH continues to assign documents and queue index actions. It does not attempt to send them until you enable the server again, by sending another `EngineManagement` action. For example:

    http://DIHhost:ACIPort/action=EngineManagement&EngineAction=Edit&ID=1&Disabled=False

This behavior is identical to when the DIH has lost contact with one of its child servers. It allows you to manually take a child server offline for maintenance.
