Current solution I'm working with there is a scheduled job to synchronize (create, update & delete) pages in different part of epi tree. As I know when a page is updated there will result in a "clear all cache". Lets say there is an updation for 1000 pages there will be lot of "clear all cache"-events and current site will not be optimized during current job is running because of the cache is cleared a lot of times.

I have read on "epiwiki.se" that you could disable clear cache in clustered environment by setting: CacheManager.ClearCacheOnLoadBalanceEventMissed = false;

If I set "CacheManager.ClearCacheOnLoadBalanceEventMissed = false;" when my scheduled job starts will this be propagated to all servers in clusterd environment or do I have to set this programmaticly on all servers by listening on some event? 

Does anyone have any recommendation how to solve this i.e not to clear cache for all pages during scheduled work is running but only when current scheduled job has finished i.e once and not 1000 times? 

Thanks in advance!
