Parameters:

backup - The remote site.

rpcCommand - The command to send.

Returns:

A XSiteResponse that is completed when the request is completed.

isCoordinator

Description copied from interface: Transport

Invoke a command on a collection of nodes and pass the responses to a ResponseCollector.

The command is only sent immediately to the first target, and there is an implementation-dependent delay before sending the command to each target.

The command is only executed on the remote nodes.
