KDFAP1801S SERVICE CHECKPOINT DATASET OWNERSHIP ACQUIRE FAILED. DSN=[ dsn].

Explanation
 			 				The service probes claimed ownership of the service 				checkpoint data set but the request failed. This message 				indicates another Tivoli® Enterprise Monitoring Server 				address space, perhaps on another system in a shared 				DASD environment, owns the service checkpoint data set, 				thus preventing this address space from having exclusive 				control. 			 		
System action
 			The service probes terminate. 		
User response
 			 				Identify the other Tivoli Enterprise Monitoring Server 				address space that owns the checkpoint data set 				specified in the KDFACTIN runtime parameter member. 				Ensure that no two Tivoli Enterprise Monitoring Server 				address spaces use the same checkpoint data set. The 				destination is the Tivoli Enterprise Monitoring Server 				Engine log file, RKLVLOG.
