In this post I will show you how to create scheduled services that could be executed on a certain period of time - hourly, daily, weekly, monthly etc. The post will expose web service that runs a Sitefinity search index. The implementation requires

 

1.Creating a web service in Sitefinity

2. Creating a console application that will be used to call the service

3. Using Windows Task Scheduler.

 

Creating a web service.

 

WebService

  • Leave the generated asmx in project's root. 
  • Make sure that the generated class is located in App_Code folder

 

In the WebMethod I'm adding getting all services using IndexDataManager object. Then I am looping through all indexes and if the name of the index that I am going to pass exists in the IndexingServiceInfo I run the index programmatically using IndexingService object

 

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Web.Services; 
using Telerik.Search; 
using Telerik.Search.Data; 
using System.Collections; 
using Telerik.Search.Engine; 
 
/// <summary>  
/// Summary description for IndexingService  
/// </summary>  
[WebService(Namespace = "http://tempuri.org/")] 
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] 
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.   
// [System.Web.Script.Services.ScriptService]  
public class IndexingService : System.Web.Services.WebService 
 
    public IndexingService() 
    { 
 
        //Uncomment the following line if using designed components   
        //InitializeComponent();   
    } 
 
    [WebMethod] 
    public void StartIndex(string indexName) 
    { 
        IndexDataManager dataManager = new IndexDataManager(); 
        IList indexes = dataManager.GetServices(); 
        IndexingServiceInfo indexServiceInfo = null
        foreach (IndexingServiceInfo service in indexes) 
        { 
 
            if (service.Name == indexName) 
            { 
                indexServiceInfo = service; 
                break
            } 
        } 
        if (indexServiceInfo != null
        { 
            Telerik.Search.Engine.IndexingService service = 
                new Telerik.Search.Engine.IndexingService(indexServiceInfo); 
            int timeout = this.Context.Server.ScriptTimeout; 
            this.Context.Server.ScriptTimeout = 4800; 
            service.Index(false); 
            this.Context.Server.ScriptTimeout = timeout; 
        } 
        else 
        { 
            throw new ApplicationException("not found name"); 
        } 
    } 

.

 

Creating Console Application

  • Create the console application

 ConsoleApplication

 

  • Add Web reference to the WebService that is located in Sitefinity website

 

  • Implement the logic in the console application to call the WebService method, pass the name of the index and finally run it.

 

namespace IndexConsoleApplication 
    class Program 
    { 
        static void Main(string[] args) 
        { 
            StartIndex("RunFromConsole"); 
        } 
        public static void StartIndex(string indexName) 
        { 
            IndexingService client = new IndexingService(); 
            client.StartIndex(indexName); 
            Console.Write("the website was indexed at" + DateTime.Now.ToUniversalTime().ToString()); 
            Console.Write("next index is scheduled for" + DateTime.Now.ToUniversalTime().AddDays(1).ToString()); 
            Console.Read(); 
        } 
    } 
}  

 

Using Windows Task Scheduler

  • Open My Computer >> Management >> System Tools >> Task Schedler

 

  •  Click Create New Task

- Triggers tab - set the time you want to run the index

- Actions tab - set the path to the exe generated by the console application.
