Abstract
Under control of a first agent, a resource controlled by a second agent is locked with a first operation identifier. Under control of the second agent: a request is received to lock the resource controlled by the second agent with a second operation identifier for a client request for a client application, wherein the resource is already locked with the first operation identifier; it is determined whether the first operation identifier and the second operation identifier are determined to be a same identifier; if it is determined that the first operation identifier and the second operation identifier are the same identifier, the request is responded to with an indication that the resource is locked with the same operation identifier; and, if it is determined that the first operation identifier and the second operation identifier are not the same identifier, the lock request is denied.
