- PM2.3 Percentage Service availability – DCC Service Management System
PM 2.2 Percentage Service availability – DCC User Interface (Production Services)This Performance Measure shall be used to assess the amount of time that the DCC User Interface is available to Users. Provision of the DCC User Interface is an activity that is performed over a period of time. The availability of the DCC Gateway Connections and other components making up the DCC User Interface covering servers, interfaces and networks shall be monitored in real-time by an infrastructure monitoring tool in accordance with Good Industry Practice. Any component unavailability will be automatically alerted to the Service Provider and where this results in an Incident an Incident shall be recorded in the DCC Service Management System; an example where component unavailability would not result in an Incident is where there is redundancy built into the infrastructure and a system 'fail over' has occurred to a back-up component. Periods of unavailability of the DCC User Interface shall be recorded in the DCC Service Management System in accordance with the Incident Management Policy. The Average Unscheduled Downtime of the DCC User Interface shall be calculated as follows: the number of complete minutes each DCC Gateway Connection is unavailable minus the number of minutes of agreed downtime due to Planned Maintenance on each DCC Gateway Connection; divided by the number of DCC Gateway Connections in the DCC Live Systems. In respect of each Performance Measurement Period (p), the Service Level for the Performance Measure shall be calculated as follows: 
Where:
AUDDUGp = the Average Unscheduled Downtime of the DCC User Interface in minutes RTp = the number of minutes within the Performance Measurement Period. The duration of the Performance Measurement Period shall be a calendar month. PM2.3 Percentage Service availability – DCC Service Management SystemThis Performance Measure measures the amount of time that the DCC Service Management System is available to DCC. Provision of the DCC Service Management System is an activity that is performed over a period of time. The availability of the components making up the DCC Service Management System, covering the associated servers, interfaces and networks shall be monitored in real-time by an infrastructure monitoring tool in accordance with Good Industry Practice. Any component unavailability will be logged on DSP systems and an Incident raised in accordance with the Incident Management Policy and, where appropriate, the business continuity and disaster recovery policies. Periods of unavailability of the DCC Service Management System shall be recorded by the DSP in accordance with the Incident Management Policy. The Unscheduled Downtime of the DCC Service Management System shall be calculated as follows: the number of complete minutes where the DCC Service Management System is unavailable to the DCC; minus the number of minutes of down time due to agreed Planned Maintenance. In respect of each Performance Measurement Period (p), the Service Level for the Performance Measure shall be calculated as follows: 
Where:
UDSMSp = the Unscheduled Downtime of the DCC Service Management System in minutes RTp = the number of minutes within the Performance Measurement Period. The duration of the Performance Measurement Period shall be a calendar month.
