I want to know how make NHibernate store my queries at 2-nd level cache for specified time
I see it only for entities cache.
Thank you for replying.
The query cache is not enabled by default. To enable it in your hibernate.cfg.xml:
<add key="hibernate.cache.use_query_cache" value="true" />
You should specify a cache region for queries. If not specified, the region will be "NHibernate.Cache.StandardQueryCache".
Session.CreateCriteria<User>()
.SetCacheRegion("UserQuery")
.List();
For syscache, cache regions are configured in you app.config:
<configuration>
<configSections>
<section name="syscache" type="NHibernate.Caches.SysCache.SysCacheSectionHandler,NHibernate.Caches.SysCache" />
</configSections>
<syscache>
<cache region="User" expiration="300" priority="3" />
<cache region="UserQuery" expiration="60" priority="3" />
</syscache>
</configuration>

I recently rewrote a large program that my company uses to conduct business. I changed to Entity Framework early on. For the most part it has been working quite well.
One issue that has annoyed me for quite some time and now I have time to look into is, a custom control that pulls a question from the database causes a strange error.
When the custom control used SQL it would actually show the question on form display in the designer. At first this was pretty cool and I liked it. After switching it to use Entity Framework 6, when I load the form in the designer I get the error
No connection string named 'wotcDB' could be found in the application
config file.
It's totally in the app.config file. In fact the program has no problem compiling and running without issue. For the longest time I would just push Ignore and go to work on the form. The question of course no longer shows up in the designer.
The User Control is part of the application. The app.config file is there, and the program both runs and deploys fine. What's causing this?
Here is my app.config, ####### is sensitive data.

Rather than deal with the issue, since only I see it. I've found an answer at
This Stack Article
I put
If (System.ComponentModel.LicenseManager.UsageMode = System.ComponentModel.LicenseUsageMode.Designtime) Then
Load_Question()
End If
in the custom control load. I don't see the question during design time, which is fine for me. My other option was to put the connection string into the EF class, which is difficult to keep up since I'm using EF-Design and not code first.
I'm trying to cluster a pair of servers with a shared Infinispan cache (Replicated Asynchronously). One always starts successfully, and registers itself properly with the JDBC database. When the other starts, it registers properly with the database, and I see a bunch of chatter between them, then, while waiting on a response from the second server, I get
`org.infinispan.commons.CacheException: Initial statue transfer timed out`
I think it's just an issue of configuration, but I'm not sure how to debug my configuration issues. I've spent several days configuring and re-configuring my Infinispan XML, and my JGroups.xml:
Infinispan:

I've tried, frankly, every configuration option I can think of, and I'm not sure why the replication keeps timing out. All communication between these servers is wide open. Sorry to just dump so much XML, but I'm not even sure how to collect more information.
Continued exploration indicated that Infinispan was pushing logs to the server.log, but - due to my configuration, this was not duplicated on the console. Further inspection revealed that I left a single element in my cache objects unserializable - making it impossible for it to be written to the wire and transferred. The logs are very specific, making this actually a very easy problem to track down once I realized where the logs were being written.
If you come here from the future, my advice is to just tail every single log you can on the working server, and see what comes up.
I am launching my first website. I have published it and I am getting this error.
The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.
What trustlevel should I use now the site is online?
<system.web>
<securityPolicy>
<trustLevel name="Full" policyFile="internal"/>
</securityPolicy>
</system.web>
are there any other web.config settings I must be aware of now I am putting the site online? Like changing the connectionstring?
Fixed it by using
<trust level="Full" />
inside <system.web>
Depending on your host provider, you may need to take out the compilers as well.
In my experience with GoDaddy I had to comment out my compilers and put trust level="Full".
Set your custom errors to On or RemoteOnly so end users do not see any error messages a.k.a "the yellow screen of death".
<system.web>
<trust level="Full" />
<customErrors mode="On" />
..... other settings in system.web ...

I am attempting to set up 2nd level caching for NHibernate 3.2 with Windows Azure Caching. So far, using https://www.windowsazure.com/en-us/develop/net/how-to-guides/cache/, I have setup Azure caching in my web.config :
<section name="dataCacheClients" type="Microsoft.ApplicationServer.Caching.DataCacheClientsSection, Microsoft.ApplicationServer.Caching.Core" allowLocation="true" allowDefinition="Everywhere" />
...
<dataCacheClients>
<dataCacheClient name="default">
<autoDiscover isEnabled="true" identifier="App.UI" />
</dataCacheClient>
I then downloaded and added the Velocity cache provider DLLs from http://sourceforge.net/projects/nhcontrib/files/NHibernate.Caches/3.2.0.GA_for_NH3.2.0GA/
Finally, my hibernate.cfg.xml is:
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<session-factory>
...
<property name="cache.use_second_level_cache">true</property>
<property name="cache.use_query_cache" >true</property>
<property name="cache.provider_class">NHibernate.Caches.Velocity.VelocityProvider, NHibernate.Caches.Velocity</property>
</session-factory>
</hibernate-configuration>
UPDATE
Solved, the dependency issue, I now get an error
{"ErrorCode:\"dcacheClient\" tag not specified in the application configuration file. Specify valid tag in configuration file."}
Thank you
I am new to web.config transformations but have it working for my connection string. However, my transforms for a custom section (nhibernate) are not being applied. Here's the transform file:
<?xml version="1.0"?>
<!-- For more information on using web.config transformation visit http://go.microsoft.com/fwlink/?LinkId=125889 -->
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<connectionStrings>
<add name="ApplicationServices"
connectionString="Data Source=.\SQLEXPRESS;Database=msmri_Users;UID=myuser;pwd=mypass;"
providerName="System.Data.SqlClient" xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
</connectionStrings>
<appSettings>
<add key="TableStorageEndpoint" value="http://127.0.0.1:10002/devstoreaccount1" xdt:Transform="Remove" xdt:Locator="Match(key)" />
</appSettings>
...
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<session-factory>
<property name="connection.connection_string" xdt:Transform="Replace" xdt:Locator="Match(name)">
Data Source=.\SQLEXPRESS;Database=mydb;UID=myuser;pwd=mypass;
</property>
</session-factory>
</hibernate-configuration>
</configuration>
All ideas appreciated. Thanks!
The trick is to add the xml namespaces to the transform configs.
Here's an example setup of the Web.config:
<section name="hibernate-configuration"
type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate" />
...
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<session-factory>
...
<property name="show_sql">true</property>
...
</session-factory>
</hibernate-configuration>
Now add the xml namespace to your transformation config. (eg Web.Release.config):
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform"
xmlns:nhib="urn:nhibernate-configuration-2.2">
...
<nhib:hibernate-configuration>
<nhib:session-factory>
<nhib:property name="show_sql" xdt:Locator="Match(name)" xdt:Transform="SetAttributes">false</nhib:property>
</nhib:session-factory>
</nhib:hibernate-configuration>
The code should be replaced the way you want now.
Well, this won't work for all situations, but based on my comment above, if this really is not supported, my solutions is to add the connection string under connectionStrings and reference it from the hibernate config section. Then my transform is still being done within the one of the default config sections. Would still love to hear that this isn't a real limitation.
Late Update: So, the problem here is with sections containing an xmlns attribute - the config transform won't handle those. The workaround in some cases (e.g., with the assemblyBinding section), where there is a containing element, is to use Transform="Replace" on the parent element, like so:
<runtime xdt:Transform="Replace">
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<qualifyAssembly partialName="MySql.Data"
fullName="MySql.Data, Version=6.2.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d">
</qualifyAssembly>
</assemblyBinding>
</runtime>
This still doesn't work for my nhibernate section, whose only parent is the configuration element itself, but . . .
