Machine Caching in SharePoint 2010

Some caching techniques in SharePoint 2010:-

1. Object Caching (Configurable)
2. BLOB Cache (Configurable) :  Open web.config in SharePoint Root Hive:
<BlobCache location="D:\BLOB\" path="\.(gif|jpg|jpeg|jpe|jfif|bmp|dib|tif|tiff|ico|png|wdp|hdp|css|js|asf|avi|flv|m4v|mov|mp3|mp4|mpeg|mpg|rm|rmvb|wma|
wmv)$" maxSize="10" enabled="true" />

3. Caching in code (Programmable)

Web Part Caching – A simple approach:-
Open Visual Studio2010 and select a WebPart form SharePoint 2010 Template:

using System;
using System.ComponentModel;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;
using System.Collections.Generic;

namespace VisualWebPartProject1.VisualWebPart1
{
    [ToolboxItemAttribute(false)]
    public class VisualWebPart1 : WebPart
    {       
        private const string _ascxPath = @"~/_CONTROLTEMPLATES/VisualWebPartProject1/VisualWebPart1/VisualWebPart1UserControl.ascx";
       
        protected override void CreateChildControls()
        {
            Control control = Page.LoadControl(_ascxPath);
            Controls.Add(control);

            List<SPList> lists = new List<SPList>();
            string status = "";

            if (HttpRuntime.Cache["SimpleSampleCache"] == null)
            {
                status = "The following items are <strong>NOT</strong> fetched from the cache<br/><br/>";

                SPWeb web = SPContext.Current.Web;
                foreach (SPList list in web.Lists)
                    lists.Add(list);

                HttpRuntime.Cache.Add("SimpleSampleCache",
                lists,
                null,
                DateTime.MaxValue,
                TimeSpan.FromMinutes(10),
                System.Web.Caching.CacheItemPriority.Default, null);
            }
            else
            {
                status = "The following items <strong>ARE</strong> fetched from the cache!<br/><br/>";
                lists = (List<SPList>)HttpRuntime.Cache["SimpleSampleCache"];
            }
           
            Controls.Add(new LiteralControl(status));

            foreach (SPList l in lists)
                Controls.Add(new LiteralControl(l.Title + " - " + l.ItemCount + " items<br/>"));   
        }
    }
}

Press F5 and add WebPart to an WebPart Page and Show the Result as follows:-

Thank You.
 

Developer Dashboard

Activating the Developer Dashboard

•    PowerShell
•    STSADM.exe
•    SharePoint Object Model (API's)

Activate the Developer Dashboard using PowerShell:-
$devdash = [Microsoft.SharePoint.Administration.SPWebService]::ContentService.DeveloperDashboardSettings;
$devdash.DisplayLevel = 'OnDemand';
$devdash.TraceEnabled = $true;
$devdash.Update()

Activate the Developer Dashboard using STSADM.EXE:-
STSADM.EXE -o setproperty -pn developer-dashboard -pv ondemand

Activate the Developer Dashboard using the SharePoint Object Model:-
using Microsoft.SharePoint.Administration;
SPWebService svc = SPContext.Current.Site.WebApplication.WebService;
svc.DeveloperDashboardSettings.DisplayLevel =
    SPDeveloperDashboardLevel.Off;
svc.DeveloperDashboardSettings.Update();

•    Off (Disables the Developer Dashboard)
•    On (Enables the Developer Dashboard)
•    OnDemand (Enables the Developer Dashboard upon request by clicking the icon in the upper right corner)

SPMonitoredScope to track performance in your applications:-
 using (new SPMonitoredScope("Monitoring"))
{
    Controls.Add(new Literal { Text = "When the awesomeness is flying... " });
               
    using (new SPMonitoredScope("Sub-Monitoring"))
    {
        Controls.Add(new Literal { Text = "Hello this is --Sub-Monitoring! " });

        using (new SPMonitoredScope("Sub-Sub-Monitoring"))
        {
            Controls.Add(new Literal { Text = "<br/>Hello this is Sub-Sub-Monitoring!" });
        }

        using (new SPMonitoredScope("Sub-Sub-Monitoring_1"))
        {
            Controls.Add(new Literal { Text = "Hello this is Sub-Sub-Monitoring_1" });
        }
    }
}

Now go and test Doveloper Dashboard to find the Result with about scope names
0.Monitoring
1. Sub-Monitoring
2. Sub-Sub-Monitoring
3. Sub-Sub-Monitoring_1
  

SharePoint 2010 Backup and Recovery

Initial Backup Configuration
•    Farm, Service Applications, Content Databases: Local Administrator Group Member
•    Site collections, sites, lists, document libraries: Farm Administrator Group Member

Backing Up the Farm
following services must be running at the time you are issuing the backup command from CA:
•    Timer Service
•    SharePoint Foundation Administration Service

    In order to be able to back up the content databases, you must have the db_backupoperator role assigned to the user you are trying to perform the backup with.
Backing Up Content Databases
Backup-SPFarm -Directory "path" -BackupMethod "Full|Differential" -Item

•    Directory: Set the backup folder
•    BackupMethod: Specify whether to run a full or differential backup
•    Item: Specify the farm, web application or (shared) service application you want to backup

    At the end of the backup/restore operation you will find either spbackup.log or sprestore.log.
Backing Up Site Collection, Lists and Document Libraries
    The preferred file extension is .bak.
Backup-SPSite -Identity "Site Collection Name" -Path "path"  [-UseSqlSnapshot] [-NoSiteLock]

we can back up single sites, lists or document libraries:
Export-SPWeb -Identity "Site/List/Library name" -Path "path" [-IncludeUserSecurity] [-GradualDelete] [-IncludeVersions]

Backing Up Log Files
Merge-SPLogFile -Path"path" -Overwrite

Initial Restore Configuration
1.    Start the SharePoint Foundation Administration Service on all farm servers
2.    Do not restart services using the Product Configuration Wizard (which causes custom configuration of the service apps to be lost).

Restoring an Entire Farm
1.    Restore-SPFarm –Directory "path" –RestoreMethod Overwrite [-BackupId "guid"]
2.    Get-SPBackupHistory -Directory "path"

Start and Stop Service using Powershell
1.    Get-SPServiceInstance | Stop-SPServiceInstance
2.    Get-SPServiceInstance | Start-SPServiceInstance

Restore Using the SQL Server Tools
•    You cannot restore the SharePoint 2010 configuration data.
•    You cannot restore SharePoint 2010 search.

Backing Up and Restoring Configuration Settings on Another Farm
What you need to bear in mind for the mentioned scenario is that you must copy and restore the configuration settings for the following elements:
•    The farm
•    Web applications
•    Service applications
1.    Get-SPWebApplication | %{$_.Name;$_.Url;%{$_.ContentDatabases|%{$_.Name}; Write-Host “” }}
2.    Get-SPContentDatabase | Dismount-ContentDatabases3.   
4.    Backup-SPFarm –Directory "path" -BackupMethod "Full | Differential"
5.    Mount-SPContentDatabase –Name "WSS_Content" -WebApplication "URL"
6.    Restore-SPFarm –Directory "path" -RestoreMethod Overwrite -ConfigurationOnly
7.    Restore-SPFarm –Directory <backup folder> -RestoreMethod Overwrite –ConfigurationOnly –Item "web app | service app"
8.    Update-SPSecureStoreApplicationServerKey –Passphrase <passphrase>
9.    Mount-SPContentDatabase –Name <db name> -WebApplication <web app URL>

Restoring Site Collections
1.    Restore-SPSite –Identity <site_collection_url> -Path <network_shared_path>\newteamsite.bak -Force

Import list and libraries
1. Import-SPWeb –Identity <site_collection_url> -Path <network_shared_path>\listname.cmp

Create a network shared folder
1. Start, Command Prompt
2. cd /
3. mkdir SPBackupFolder
4. Cacls SPBackupFolder /G <DomainName>\Administrator:F
5. Net Share SPBackupFolder=C:\SPBackupFolder /GRANT:<DomainFolder>\Adminstrator,FULL
-----------------------------------------------------------------------
Get-Help Restore-SPSite -detailed
Get-Help Import-SPWeb -detailed
Get-Help Get-SPBackupHistory -detailed
Get-SPBackupHistory –Directory <network_shared_path>\SPBackup
