Question

Anyone know how to configure an ActiveRecord/nhibernate application to use Memcache as the 2nd level cache?

Answer 1

Start with the ActiveRecord docs on second level cache configuration. Then, for specific information about Memcached, see this question.

You’ll end up with a config similar to this:

<activerecord>      
  <config>
    <add key="connection.driver_class" value="NHibernate.Driver.SqlClientDriver" />
    <add key="dialect" value="NHibernate.Dialect.MsSql2005Dialect" />
    <add key="connection.provider" value="NHibernate.Connection.DriverConnectionProvider" />
    <add key="connection.connection_string" value="Data Source=.;Initial Catalog=test;Integrated Security=SSPI" />    
    <add key="cache.provider_class" value="NHibernate.Caches.MemCache.MemCacheProvider, NHibernate.Caches.MemCache"/>
    <add key="cache.use_second_level_cache" value="true"/>
    <add key="cache.use_query_cache" value="true"/>
  </config>      
</activerecord>
