Your code seems to be OK. The only thing that can be problematic is the interval 4*60*60 is too short which is 14.4 seconds.

Moreover it seems like you're not directing the intent to a specific receiver. you should do like this:

Calendar calendar = Calendar.getInstance();
Intent intent1 = new Intent(MainActivity.this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0,intent1, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager am = (AlarmManager)this.getSystemService(this.ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 1000 * 60 * 60, pendingIntent);

And you should catch it in:

public class AlarmReceiver extends BroadcastReceiver{

@Override
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub

    long when = System.currentTimeMillis();
    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);

    Intent notificationIntent = new Intent(context, EVentsPerform.class);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
            notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);


    NotificationCompat.Builder mNotifyBuilder = new NotificationCompat.Builder(
            context).setSmallIcon(R.drawable.applogo)
            .setContentTitle("text")
            .setContentText("text")
            .setWhen(when)
            .setContentIntent(pendingIntent)
    notificationManager.notify(yourId, mNotifyBuilder.build());

}

}

Add this to your manifest file:

 <!-- permission required to use Alarm Manager -->
 <uses-permission android:name="com.android.alarm.permission.SET_ALARM"/>

 <!-- Register the Alarm Receiver -->
 <receiver android:name="com.example.alarmmanagernotifcation.AlarmReceiver"/>
