What is Distributed Cache Service?

Posted By :abhays     Posted Date :May 06, 2014    Points :40   Category :SharePoint 
The Distributed Cache service provides caching features in SharePoint Server 2013. The Distributed Cache service is built on Windows Server AppFabric, which implements the AppFabric Caching service. Windows Server AppFabric installs with the prerequisites for SharePoint Server 2013.

How can I see what assemblies are installed in the global assembly cache?

  
The .NET Framework ships with a Windows shell extension for viewing the assembly cache. Navigating to % windir%\assembly with the Windows Explorer activates the viewer. (More...)

What is SQL Cache Dependency in ASP.NET?

  
SQL cache dependencies is new technique in ASP.NET 2.0 onwards which can automatically invalidate a cached data object just like a Dataset. when the related data is modified in the database. So for instance if you have a dataset which is tied up to a database tables any changes in the database table will invalidate the cached data object which can be a dataset or a data source.

To enable this we need a syntax that is as follows in visual studio command prompt type the following command

aspnet_regsql -ed -E -d (More...)

What is the Transport Protocol you use to call a Web Service ?

  
SOAP (Simple Object Access Protocol) is the preferred protocol. (More...)

What is SQL Server Service broker?

  
Service Broker is a unique feature in Microsoft SQL Server 2005 which is used to by internal or external processes to send and receive guaranteed, asynchronous messages by using extensions to Transact-SQL Data Manipulation Language (DML).

It's a platform for building a new class of loosely coupled services for database applications. Service Broker not only brings asynchronous, queued messaging to database applications but significantly expands the state of the art for reliable messaging.

The key components of SQL Server Service broker are
.Queue stores the messages for a particular service.
.Dialog is a conversation between two services.
.Conversation group is a group of related conversations. Every conversation belongs to exactly one conversation group.
.Activation specifies a stored procedure that will handle messages destined for a particular service. (More...)

What are the essential components of SQL Server Service broker?

  
Queues
Service Broker uses queues to provide loose coupling between the message sender and the message receiver. The sender can put a message in a queue and then continue on with the application, relying on Service Broker to ensure that the message reaches its destination. Queues permit a lot of scheduling flexibility.

Dialogs
Dialogs are bidirectional streams of messages between two endpoints. All messages in a dialog are ordered, and dialog messages are always delivered in the order they are sent. The order is maintained across transactions, across input threads, across output threads, and across crashes and restarts.

Conversation Groups
It's a way of grouping all the dialogs that are used for a particular task. All the dialogs associated with processing a particular order would be grouped into a single conversation group. The conversation group is implemented as a conversation group identifier, which is included with all messages in all dialogs contained in the conversation group. When a message is received from any of the dialogs in a conversation group, the conversation group is locked with a lock that is held by the receiving transaction. For the duration of the transaction, only the thread that holds the lock can receive messages from any of the dialogs in the conversation group. This makes our order entry application much easier to write because even though we use many threads for scalability, any particular order is only processed on one thread at a time. This means we don't have to make our application resilient to problems that are caused by the simultaneous processing of a single order on multiple threads.

Activation
You use the activation feature of Service Broker to specify a stored procedure that will handle messages destined for a particular service. When messages arrive for a service, Service Broker checks whether there is a stored procedure running that can process the messages. If there isn't a running message-processing stored procedure, Service Broker starts one. The stored procedure then processes messages until the queue is empty, after which it terminates. Moreover, if Service Broker determines that messages are arriving faster than the stored procedure can process them, it starts additional instances of the stored procedure until enough are running to keep up with the incoming messages (or until the configured maximum number is reached). This ensures that the right number of resources for processing incoming messages are always available. (More...)

What are Cache - Dependencies types?

  
When anyone add an item to cache, he/she can define the dependency relationships that can force that item to be removed from the cache under specific activities of dependencies.

For example: If the cache is dependent on file and when the file data changes you want the cache object to be updated.

Following are the difference dependencies:
(a) File Dependency :
Allows invalidating a specific cache item when a disk based file or files change.
object errorData;
//Load errorData from errors.xml

CacheDependency fileDependency =
new CacheDependency(Server.MapPath("errors.xml"));
Cache.Insert("ERROR_INFO", errorData, fileDependency);

(b) Time based expiration :
Allows to invalidate a specific cache item depending on predefined time.


//Absolute Expiration

Cache.Insert("EMP_NAME", "Shubhabrata", null,
DateTime.Now.AddDays(1), Cache.NoSlidingExpiration);

//Sliding Expiration

Cache.Insert("EMP_NAME", "Shubhabrata", null,
Cache.NoAbsoluteExpiration, TimeSpan.FromSeconds(60));


(c) Key dependency :
Allows to invalidate a specific cache item depending when another cache item changes.


string[] relatedKeys = new string[1];
relatedKeys[0] = "EMP_NUM";
CacheDependency keyDependency = new CacheDependency(null, relatedKeys);
Cache["EMP_NUM"] = 5435;
Cache.Insert("EMP_NAME", "Shubhabrata", keyDependency);
Cache.Insert("EMP_ADDR", "Bhubaneswar", keyDependency);
Cache.Insert("EMP_SAL", "5555USD", keyDependency); (More...)

Can you place two .dll files with the same name in GAC (Global Assembly Cache)?

  
Yes, provided both have different versions.
GAC is a Folder that contains .dll that have strong name. So we can keep myproject.dll and myproject.dll two files into GAC with different version like 1.0.0.0 and 1.0.0.1 (More...)

Can a .NET web application consume Java web service?

  
Yes Offcourse.Actually Webservices are independent to language. it depends on WSDL and SOAP. so any one can develope the Webservices anddisclose the wsdl and users can consume the webservices.wsdl and soap both are xml based.. and all languages having xml parsing
capability and access to http protocol will be able to work with Webservices. (More...)

Is the ASP.NET AJAX Control Toolkit(AjaxControlToolkit.dll) installed in the Global Assembly Cache?

  
No. You must copy the AjaxControlToolkit.dll assembly to the /Bin folder in your application. (More...)

How do you invoke a web method of web service in AJAX?

  
In order to use a webmethod of a webservice, we need to add the reference of webservice in the section of ScriptManager. Under services you have to configure the servicepath.

< asp:ScriptManager ID="ScriptManager1" runat="server">
< Services>
< asp:ServiceReference Path="..\service1.asmx" />
< /Services>
< /asp:ScriptManager>

Inside JAvascript Use methods of this service directly like
service1.methodname() (More...)
