Go to Configuration > Global Settings > Maintenance Settings to adjust the maintenance settings for your OpenX installation.
- Automatically perform maintenance during delivery if scheduled maintenance is not set up: this option is enabled by default.
- Maintenance Operation Interval (minutes): select a value from the dropdown to determine how often you would like maintenance to be performed. OpenX uses this information to calculate delivery priorities. When you begin using OpenX you are unlikely to notice a difference in these priorities for some weeks, as several weeks' data are necessary before meaningful adjustments can be made to the calculations. It is not advisable to change this value without good reason, or without first allowing enough time to elapse to affect changes in delivery.
Operation intervals are described in detail in the Prioritization engine developer white paper.
- Update advertisement priorities immediately when changes made in the UI: this checkbox is selected by default. This means that priorities are updated immediately. When this setting is not selected, ad priorities are updated during the next scheduled maintenance.
When you are happy with your selections, click Save Changes.
