With the VDBManagement
action, you can dynamically (without restarting the Distributed Action Handler) bring VDBs online or take them offline, when running in non-Mirror mode.
If a VDB 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).
