Given how the cache factory works, you can't set new values for cache
properties after it is created by configuration. You might change the
Configuration object and recreate the SessionFactory, but that would
be a heavy task...
A method I use to clear a whole cache region (not tested with
SysCache) is:
public static void ClearCacheRegion(ISession session, String
regionName)
{
var properties = new Dictionary<String, String>();
session
.SessionFactory
.Settings
.CacheProvider
.BuildCache(regionName, properties)
.Clear();
}

To remove objects from second-level cache, use some of the
ISessionFactory.Evict*() methods. For details, see:
