Global settings - maintenance

In the Maintenance Settings section, you can:

• The Automatically perform maintenance during delivery if scheduled maintenance is not set up option is enabled by default.
• You can change the Maintenance Operation Interval (minutes) to adjust how often maintenance is performed. OpenX uses this information to calculate delivery priorities. You are unlikely to notice a difference in these priorities for some weeks because OpenX requires several weeks' information before it can make meaningful adjustments to the calculations. It is not advisable to change this value without good reason, or without allowing a reasonable period to elapse before expecting to notice any changes in delivery. 
  
  

  Operation intervals are described in detail in the Priorisation engine developer white paper.

  
  

• The option to Delete raw statistics after processing is enbaled by default. This option reduces the amount of information stored in the database.
• You can change the Grace period before deleting processed statistics (seconds) to reduce (or extend) the amount of time raw statistics are stored in the database before they are deleted.

In the Priority Settings section you can select to Update advertisement priorities immediately when changes made in the UI. Select this checkbox to ensure priorites are updated immediately. When this setting is not selected, advertisement priorities are updated during the next scheduled maintenance.

Always remember to click Save Changes after performing any of the above actions.
