R/W(+): Dynamic Read / static and dynamic Write

For online temporary change or permanent change, use the admin+ utility to modify the parameter value for a specific instance. A restart is needed for permanent changes.

This parameter enables or disables the scheduler which is in charge of refreshing the offer cache into each rater.

The cache refresh mechanism works with two caches. When the user modifies an offer or any object belonging to an offer (in the updater), the modification is propagated into a secondary offer cache in all the raters. The modification becomes effective when the primary and the secondary offer caches (in each rater) are switched.

This mechanism allows us to avoid blocking the rating process during the cache update.

Cache update can be triggered manually or automatically at a given date/time by a scheduler. By setting this parameter to true, the user activates the automatic mode according to a recurrence period specified into the REFRESH_SCHEDULER_RECURRENCE parameter.
