[2/8/2013 13:11:26:653 EDT] DCPC0331I: The application placement controller Output is
(Map Time=1360347071465)
DCPC0335I: The Application Placement Controller is suggesting to start a server for xdhv01v04Cell02/pc1dc1 to meet the required number of running instances.
The application placement controller prints input and output information each time it runs a processing cycle. The input displays the current cluster and node information, and the output displays any actions suggested by APC. In the previous example, APC suggests starting a server for the cluster xdhv01v04Cell02/pc1dc1 to meet the minimum instances requirement. To confirm this suggestion, review the input data: minimum instances is 1 (Min/Max Instances=1/2147483647), and there are currently no running servers (Cluster Placements: None).
