Note the following points when you start up or stop service adapters and business processes, start the standard reception during operations in the High availability cluster configuration and N-to-1 cluster configuration.

• When you start up and stop service adapters and business process
  Use the following procedure for starting up and stopping service adapters and business processes:
  
  1. Disconnect the service requester network to prevent service component execution requests from being accepted in the executing and standby nodes.
  2. You start or stop the same service adapter and business process at both the executing and standby nodes.
  When node switching occurs in the high availability cluster configuration, the status of service adapters and business processes is not inherited. Therefore, if a service adapter is terminated in the running executing node and node switching occurs in this status, consistency is lost in the status of service adapters and business processes in the executing and standby nodes.
  
• When you stop the standard reception
  To stop the standard reception, you first prevent execution requests from being accepted regardless of the standard reception status, by disconnecting the service requester network. After that, you stop the standard reception. If node switching occurs in the high availability cluster configuration, the standard reception is started in the standby node. To temporarily prevent execution requests from being accepted at the running executing node, the standard reception is terminated at the executing node. If node switching occurs in this status, execution requests may be accepted at the standby node.
  

If the system switches over to the High availability cluster configuration while the operating screen of the Screen Platform is still running during the operations in the High availability cluster configuration or the N-to-1 cluster configuration, various statuses displayed in the window correctly cannot be reflected.

When you re-execute the business process from another HCSC server during operations in the load-balancing cluster configuration and the N-to-1 cluster configuration, if you want to re-execute the business process after the node switching processing to the standby node in the High availability cluster configuration, store each type of information in the following location:

Type of information	Storage location of information
Work folder	Common disk device
Common folder
Input output permission file used in the file adapter
Text file and attachment of the mail body used in the mail adapter	Local disk device #
Definition file used in HCSC server operations
Definition file used in HCSC components

#

Set the same value in each HCSC server in the case of load-balancing cluster configuration and N-to-1 class configuration, and in the executing node and the standby node in the case of High availability cluster configuration.
