NHibernate с Appfabric Velocity падает после очистки региона - PullRequest
0 голосов
/ 25 мая 2011

Я использую NHibernate с Velocity в качестве провайдера 2-го уровня кэша.

Мне нужно очистить регион.Я использую этот код:

_sessionFactory.EvictQueries("Authorization");
var authCache = _sessionFactory.GetSecondLevelCacheRegion("Authorization");
authCache.Clear();

authCache.Clear () фактически вызывает метод NHibernate.Caches.Velocity.VelocityClient.Cache.

Область очищена правильноНо сразу после этого открывается новый сеанс и делается запрос к объекту, который был ранее кэширован.Он пытается GetAndLock в VelocityClient.Взрыва.Сбой AppFabricCachingService (см. Журнал событий ниже)

Правильно ли очищается кэш?В чем моя ошибка?

Это известная ошибка AF Cache.Очистка области приводит к сбою при наличии заблокированных элементов кэша.См. Эту ветку:

Исключение при очистке системных областей

Обходной путь: вместо очистки следует выполнить перезагрузку кластера во включенной консоли AF Cache PS.
