To ensure system and data integrity, you must shut down the N4 system using the proper procedure.
To shut down the N4 system:
Shut down all ECN4Web and N4 Billing client workstations.
Shut down the XPS clients, including any server-room clients.
Stop the ECN4Web service.
Stop the ECN4 service.
Stop the XPS service.
Stop the bridge daemon service.
Stop the Standby Center node.
Because the status of the Standby Center node is "INITIALIZING," in Windows operating systems, you must stop the service using the command line. Using a right click, open the Command Prompt from the Windows Start menu, and choose Run as administrator. Confirm in the User Account Control dialog that you want to allow the program to make changes to the computer. Then type taskmgr.exe into the command line. The Windows Task Manager appears. On the Services tab, select n4center. Right click and select Stop Service.
Stop the services for all of the Cluster nodes.
Stop the service for the Center node.
Notes
If you attempt to shut down all the N4 nodes at the same time, you may experience a delay of up to 10 minutes. When a cluster node service is stopped, the in-memory cache data is distributed by Hazelcast to other cluster nodes in order to maintain the integrity of the cache. This usually takes 30 seconds to 1 minute before the node shuts down. But when all the nodes are shut down at once, Hazelcast tries to distribute cache data on each node to other nodes that are also shutting down and trying to distribute their own cache data. Hazelcast eventually times out at 10 minutes. This causes the shutdown process to be delayed.
