EngineManagement

Take child servers online and offline. With the EngineManagement action, you can dynamically (without restarting the Distributed Action Handler) bring child IDOL servers online or take them offline.

If a child server is marked as offline, the Distributed Action Handler sends no requests (even polling requests) to it, until it is brought back online again.

Note: This is an administrative action that can be sent only from Distributed Action HandlerAdminClients (which are set in the Distributed Action Handler configuration file [Server] section).

Example

http://Hobbes:25000/action=EngineManagement&EngineAction=PowerDown&EngineID=2,4

This action uses port 25000 to take offline the child IDOL servers with IDs 2 and 4 of the Distributed Action Handler on the host Hobbes.
