Handling of communication errors

HiRDB processing: Returns control, issuing a message indicating that a communication error occurred in a specified transaction.

HiRDB administrator's action: Check the cause of the communication error, terminate HiRDB, and take appropriate action to correct the error.; It might not be possible to terminate HiRDB normally after a communication error. If this is the case, terminate HiRDB forcibly. If HiRDB still will not terminate, recover each unit if units can be terminated or started individually. Otherwise, shut down the entire system, eliminate the cause of the error, then restart the system.
