    An extreme load situation in the database caused an unexpected database crash and required full system start up to bring the system back to full functionality.

    Ex Libris engineer’s preliminary analysis is that in order to deal with this situation in the future, the database server requires additional memory.

    How is Uptime Calculated?

    The uptime calculation is based on the following calculation (as defined in the Service Level Agreement):

    "Uptime" means the total period in minutes during which the Service is available for access and use during this period.

     

    Uptime Percentage” means Uptime expressed as a percentage, calculated in accordance with the following formula:   

      

     Uptime Percentage = X /(Y–Z) × 100    

    Where: 

      X = Uptime

      Y = Last 12 months period

      Z = The duration (in minutes) of any SLA Exclusions* during these 12 months

     

    *SLA exclusions are defined in the contract SLA (e.g. Scheduled maintenance, etc.)
