When there is any activity wants to happen automatically in share
point then there is one quick solution and that is Timer job.Timer job
runs in a specific Windows service for SharePoint Server.Its very easy to
create the timer job and deploy to share point server.Timer job can
be set from seconds to years period.Timer job contains a definition of the
service to run and specifies how frequently the service is
started. SharePoint timer service runs the the timer job.This feature
is debugged uisng OWSTimer process.
Below is one example which gives idea of creating and deploying the
timer job. It definately help you in enhansing your knoweldgebase.
Steps for creating the timer job.
1. Create new project from visual studio with share
point template
2.Once the project is selected now its time to to set the SP
server url. Since the timer job can not be deployed as sandbox solutions so
select the farm solution for deployment.
3. Open the solution explorer and right click on project name
and add the new item and that is class.
4. After adding the class now add the feature because the timer is
deployed as feature to share point server. Right click on feature
and select add feature and sets its scope.
5. Add the event receiver by right clicking on the feature.
6. Once all the required files are added in solution now its time to
play with code. So open the class which we added in step 3 and add code as
below.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SharePoint.Administration;
using Microsoft.SharePoint;
namespace TestTimerJob
{
public class TestTimerJob : SPJobDefinition
{
public TestTimerJob()
: base()
{
}
public TestTimerJob(string jobName,
SPService service, SPServer server, SPJobLockType targetType)
: base(jobName, service,
server, targetType)
{
}
public TestTimerJob(string jobName,
SPWebApplication webApplication)
: base(jobName,
webApplication, null, SPJobLockType.ContentDatabase)
{
this.Title = "Test Timer
Job";
}
public override void Execute(Guid
contentDbId)
{
SPSite oSPSite = new
SPSite("http://MySharepointTestServer");
SPWeb oSPWeb =
oSPSite.RootWeb;
oSPWeb.AllowUnsafeUpdates =
true;
SPList testList =
oSPWeb.Lists["TestList"];
SPListItem newTaskItem =
testList.Items.Add();
newTaskItem["Title"]
= "NewItem";
newTaskItem.Update();
oSPWeb.AllowUnsafeUpdates =
false;
}
}
}
6. Now add the code for event receiver class for
its scheduler logic, activation and deactivation method as like
below.
using System;
using System.Runtime.InteropServices;
using System.Security.Permissions;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Security;
using Microsoft.SharePoint.Administration;
namespace Test.Features.Feature1
{
///
/// This class handles events raised during feature
activation, deactivation, installation, uninstallation, and upgrade.
///
///
/// The GUID attached to this class may be used during
packaging and should not be modified.
///
[Guid("1d48fa2f-edce-428c-bfea-bb9fc473f9ca")]
public class Feature1EventReceiver : SPFeatureReceiver
{
// Uncomment the method below to handle the
event raised after a feature has been activated.
const string List_JOB_NAME =
"TestListTimer";
public override void
FeatureActivated(SPFeatureReceiverProperties properties)
{
SPSite site =
properties.Feature.Parent as SPSite;
// make sure the job isn't already
registered
foreach (SPJobDefinition job
in site.WebApplication.JobDefinitions)
{
if (job.Name ==
List_JOB_NAME)
job.Delete();
}
// install the job
TestTimerJob listLoggerJob =
new TestTimerJob(List_JOB_NAME, site.WebApplication);
SPMinuteSchedule schedule =
new SPMinuteSchedule();
//SPHourlySchedule schedule1 =
new SPHourlySchedule();
//SPDailySchedule sc = new
SPDailySchedule();
//SPYearlySchedule scy = new
SPYearlySchedule();
schedule.BeginSecond = 0;
schedule.EndSecond = 59;
schedule.Interval = 5;
listLoggerJob.Schedule =
schedule;
listLoggerJob.Update();
}
// Uncomment the method below to handle the
event raised before a feature is deactivated.
public override void
FeatureDeactivating(SPFeatureReceiverProperties properties)
{
SPSite site =
properties.Feature.Parent as SPSite;
// delete the job
foreach (SPJobDefinition job
in site.WebApplication.JobDefinitions)
{
if (job.Name ==
List_JOB_NAME)
job.Delete();
}
}
// Uncomment the method below to handle the
event raised after a feature has been installed.
//public override void
FeatureInstalled(SPFeatureReceiverProperties properties)
//{
//}
// Uncomment the method below to handle the
event raised before a feature is uninstalled.
//public override void FeatureUninstalling(SPFeatureReceiverProperties
properties)
//{
//}
// Uncomment the method below to handle the
event raised when a feature is upgradin8. g.
//public override void
FeatureUpgrading(SPFeatureReceiverProperties properties, string
upgradeActionName, System.Collections.Generic.IDictionary
parameters)
//{
//}
}
}
7. Build the solution and deploy to the server.
8. The above deployment can be done on VM or your development server but
if you have to deploy it to the production then you have to use STSADM or
PoweShell command.
shell command” - Enable-SPFeature -Identity “FeatureName” -Url
“https://Servername″
STSADM - stsadm -o activatefeature -fileName
MyTestTimer\TestTimerFeature.xml -url -force
stsadm -o
deactivatefeature -fileName MyTestTimer\TestTimerFeature.xml -url -force
