SharePoint site down “An application error occurred on the server” web.config error

Hi All,

 

Recently I got below error message which you might have seen. This is a very common and generic error message which can confuse you a lot. You may face this issue in all versions of SharePoint like SharePoint 2007, 2010, 2013 or SharePoint 2016. First let us look at the error message
#################### Error Start #############
Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be view able on remote machines, please create a <customErrors> tag within a “web.config” configuration file located in the root directory of the current web application. This <customErrors> tag should then have its “mode” attribute set to “Off”.

<!– Web.Config Configuration File –>

<configuration>
<system.web>
<customErrors mode=”Off”/>
</system.web>
</configuration>
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the “defaultRedirect” attribute of the application’s <customErrors> configuration tag to point to a custom error page URL.

<!– Web.Config Configuration File –>

<configuration>
<system.web>
<customErrors mode=”RemoteOnly” defaultRedirect=”mycustompage.htm”/>
</system.web>
</configuration>

#################### Error End #############

We can see that error message says something about web.config file. Here is what we need to do.
1. Open IIS management console
2. Start > RUN > Inetmgr > Expand server
3. Expand the site you are getting this error on > right click > explore

Here you should be able to see a web.config file. If this web.config was recently modified by someone, please check with your team if anyone has recently modified this file, tried to deployed a farm\web application solution or run psconfig wizard on any of the SharePoint server in farm.
Note: If you have multiple SharePoint server, try the same on all the servers

In most cases, it is a web.config change done by someone from within the team which cause this issue.
If no one has done any changes:
1. Make a copy of this web.config file and open the original file. Search for “callstack” and set the value to True, again search for customerrors set it to OFF.
2. Rename the recent web.config to web.config.old with today’s date and revert the most recent web.config(date and time) file to web.config
3. Install Examdiff tool on a computer and copy the most recent web.config file and new web.config to identify the changes.

These steps will help you identify the actual cause of this error.

 

Myth Buster for SharePoint SQL RBS

Hi All,

 

In this article I would try to share my experience about SharePoint on SQL RBS. This article may help you decide if you should use SQL RBS with SharePoint or any other product.

 

This is my personal opinion about SQL RBS with SharePoint. I would suggest you to cross check below furnished details before taking final decision. Microsoft keeps enhancing its product so some of these may be fixed\resolved\changed.

 

Let’s first discuss what is SQL RBS? Normally when you upload a document, image, video, audio, etc on your SQL server it is stored in MDF (Master database file) of your SQL content database. As per my past experience when you upload anything to a content management system, you would revisit only 20 % of data uploaded, rest 80 % of data is never visited but used for record only purpose. IT pro’s suggest that you should keep your SQL content database on RAID 10 hard disk or SAN which is pretty expensive.

 

To resolve this issue Microsoft came out with SQL RBS which allows you to store your Files\BLOB outside (File system) of SQL database. This means you can use a Raid 0 drive to store BLOB files (image, video, document, etc). RBS is intended to lower storage costs by allowing you to store large read-intensive BLOBs on less expensive drives.

 

1st Myth of SQL RBS: Additional Storage for Content database.

This is the biggest myth about SQL RBS. Microsoft Suggest that your content database should be below 200 GB. Now days when we have a USB stick with 100 GB, a Content management server restricted to 200 GB is not a good deal. To overcome this issue few IT admin plan to use SQL RBS because RBS stores files outside of SQL server hence decrease the size of content database.

Reality: RBS does not increase the storage limits of content databases. All limitations still apply to RBS-enabled content databases. If you are using Remote BLOB Storage (RBS), the total volume of remote BLOB storage and metadata in the content database must not exceed the 200GB limit.

 

2nd Myth of SQL RBS: Files stored on FILESYSTEM through RBS cannot be accessed directly.

IT Pros and lot of other articles says that we cannot open the file directly from BLOB FILESYSTEM. We have to go through SQL database in order to read these files.

Reality: I was able to access FILESYSTEM where the BLOB files were stored and was able to open my txt, bmp, jpg, etc files. SharePoint is known for its Item level Security. So far SharePoint security was never compromised and access is only available on need to know basis. If any users who has access to FILESYSTEM can open any file stored in SharePoint without having access on SharePoint is a security issue. Also encryption is not supported on BLOBs, even if Transparent Data Encryption is enabled.

 

3rd Myth of SQL RBS: Better performance I hear a lot of IT PRO who comment that they would get better performance if FILES\BLOBS are stores outside of SQL Server.

Reality: I would accept this when we are using SharePoint to store Hugh amount of data files (70-80 % of BLOB). When I asked these IT Pros how much data is stored on dbo.docs, dbo.AllDocStreams, dbo.DocStreams, dbo.AllDocVersions, dbo.alldocs, etc table, they are not aware of same or they don’t bother. When you offload 70-80 % of data from your MDF file and store it FILESYSTEM you may feel better performance. If our content database stores BLOB files not more then 30-35 % then it would not make sense to go with RBS. Let me explain you why I say that, when you configure RBS you create number of additional tables on your content database. This means when we upload BLOB to SharePoint it will execute additional query to store data. Here SQL will first import image files, and then it may split the file based on size of file and then store it to FILESYSTEM. Again this process is reversed when we try to open or query the BLOB file. This will increase disk IO, RAM and processing power. Now if consumption of my resources is increased, how can I expect better performance? RBS does not support using data compression but data is compressed when uploaded to SQL MDF file. Microsoft says “Although using RBS with files larger than 1 MB can improve I/O and processor performance, using RBS with files smaller than 256 KB might decrease overall performance. Storing the BLOBs inline in the content database is more efficient with smaller files”

 

4th Myth of SQL RBS: Ease in management

A lot of IT Pro’s also comment that it is easy to manage smaller SQL databases, Better Technology, Ease in configuration, etc.

Reality: Why you want to take an additional Load of configuration anything extra on SQL. If any feature is available does not mean you should use it. Implementation of these features depends on its pros\cons and specific requirement of the feature. Also when you backup the database, it will backup all the files from FILESYSTEM along with SQL MDF\LDF files. Sizes of these databases backup does not decreases but it increase because RBS does not perform any compression. If you plan High availability through Mirroring or Log shipping, you need to follow additional steps to configure the same.

That’s it from my side. Feel free to comment or connect with me if you feel any of the above information is incorrect.

SharePoint : Redirect to different home page for authenticated users

Hi All,

Today I got a requirement where authenticated users should be redirected to a different page, here is how I achieved it.

Editing the exiting SharePoint Landing page, then add a new content editor Web Part on the page. Now edit the content editor webpart and click on Web part properties on top. Now select “Embed code” under Insert for content editor webpart, add below script in :


<meta http-equiv=”refresh” content=”5;url=http://sharepoint/SitePages/Home.aspx”>


Try to check if your site is redirect to the new site.

If the redirection is working fine then we will restrict this script only for authenticated users. We need to edit the page again and select Edit webpart. Under Advance setting Set Target Audience as “NT Authenticated users”

Hope this helps you.

What is a Site Collection in SharePoint?

There are lot of confusions between Site Collection, sites and web application so though I will try to put some light on same. A very high level overview of a Site Collection is that Site collection share common features like Content types, Templates, Site columns, permissions, Web Parts etc. In other words a site collection groups together websites, and (perhaps most importantly) the security data for these websites. A site Collection stores references to a bunch of information critical to any web site. This information includes, but is not limited to:

–Web Parts

–Users which have access to the website

–Themes

–Sandbox Solutions

–MasterPages

–List Templates

 

 

Site Collection facilitates better administration of our internet\intranet websites. Let me explain using an example. We have a company’s intranet site and that intranet site (http://intranet) has multiple departments based sub sites like Finance, Sales, Support, etc. If I need to check something related to Finance, I can simply go to http://intranet/finance and try to find my relevant information in through Shared Document library, Blogging and much more. I would have access to all commonly used information\documents through a single intranet URL.

 

To the Site Collection all the websites within it are in a flat hierarchy which developers can see using spsite.allwebs or using dbo.allwebs table in content database.

 

Normally each web application has at least 1 Site Collection but it can have many however every web application has only 1 Top Level Site collection. General setting like Recycle bin and Quotas are organized at site collection level. Most important is each site collection can only use a single content database though multiple site collections can us the same content database.

 

Sites and subsites in a web application are actual place where content is stored. A site can be a top-level site or a sub site of the top level site. Not to confuse you but even a Sub sites can have other sub sites and so on. It is a free like structure. A site can inherit its parent’s permissions or define its own.

 

 

Microsoft recommended limiting the number of site collections in a content database to 5,000. However, up to 10,000 site collections in a database are supported. Microsoft decided this parameter after analyzing speed of upgrade, SharePoint performance, etc. The larger the number of site collections in a database, the slower the upgrade with respect to both database upgrade and site collection upgrades.

 

 

Exceeding the 5,000 site collection limit puts you at risk of longer downtimes during upgrades. If you plan to exceed 5,000 site collections, Microsoft recommend that you have a clear upgrade strategy to address outage length and operations impact, and obtain additional hardware to speed up the software updates and upgrades that affect databases.

 

The maximum recommended number of site collections per SharePoint farm is 500,000 Personal Sites plus 250,000 for all other site templates.

 

You can create a very large total number of web sites by nesting subsites. For example, in a shallow hierarchy with 100 sites, each with 1,000 subsites, you would have a total of 100,000 web sites. Or a deep hierarchy with 100 sites, each with 10 subsite levels would also contain a total of 100,000 web sites.

 

Note: Deleting or creating a site or subsite can significantly affect a site’s availability. Access to the site and subsites will be limited while the site is being deleted. Attempting to create many subsites at the same time may also fail.

 

Microsoft recommends a limiting of 200 GB for each site collections. This 200 gb includes RBS blob files on SQL server.

 

How we create a site collection?

Open Central Admin > Application management > Create Site Collection > Select the URL  and fill in other details > Click OK.

You can also use below Powershell command:

New-SPSite -URL http://itfreesupport.com -OwnerAlias inder@itfreesupport.com  -template “STS#0”

 

How to create a subsite?

Browse your site collection > Select setting button on right top corner > select “site contents” > select new subsite > Provide the URL and fill in other details > click OK.

You can also use below Powershell command:

New-SPWeb http://itfreesupport/subweb1 -Template “STS#0”

Note: Site collection can only be create from Central admin or SharePoint server where as subsite can be created from any machine using site collection URL

What are types of SharePoint installation? what is difference between Farm and standalone?

A very common answer to 1st question is, we have Standalone and Farm installation but when it comes to SharePoint 2010 and SharePoint 2013 I say we have Standalone and complete installation. Why I said “complete” is because when we install Complete edition of SharePoint 2010\2013 we get option to create farm where as in SharePoint 2007, you get option to select Farm or Standalone while we are installing SharePoint. So the trick here is people mention “complete” instead of “Farm” for better understanding.

 

At first glance, standalone installations seems best for development purposes. The benefits appear to be:
1. Standalone will automatically install SQL Express for you(No SQL server installation needed)
2. Standalone will install using local accounts(no domain controller needed)

 

In my view a SharePoint standalone setup should be sufficient for development unless you are developing against SharePoint Enterprise only features.(I assume SharePoint foundation or Standard). SharePoint developer save a TON of hassle by having Visual Studio and SharePoint installed on the same OS (e.g. F5 to compile, run and debug all in one go) rather than using separate servers (VM or otherwise) and performing the incantations required to get remote debugging working.

 

Lots of sites say you need to setup your Development environment with Windows server 2008  but that’s not necessary as Windows 7 (x64 with SharePoint 2010 and SharePoint 2013) or even Windows Vista(with SharePoint 2010) can be used as Development environment.

 

But I would like to add that a stand-alone environment is sufficient for a development environment, however I would recommend to mimic a stand-alone by choosing a farm installation. You can install a higher version of SQL server(e.g. SQL server 2014 with advance features or SQL server developer edition) for better advantage. Not everyone know what SQL server. No everyone know but regardless of how many physical CPUs you have on your SQL server and how many cores per physical CPU, each SQL Express instance will be limited to a single CPU core. A similar cap is applied to amount of RAM which can be used by SQL server Express edition.

 

Standalone installation have their own disadvantage like limitations of 4 GB SQL database. connection to SQL from a remove machine, need to separately install Management studio, etc. Moreover if any of your project needs to test a multi-server setup, you cannot mimic the same on a Standalone installation.

 

On the other hand a farm\complete installation allows you to add other servers and SQL a different SQL server so as to keep you running out of resources. You can install SQL server on a different machine with good resources and allow all your team member to connect to single SQL server for development purpose. SQL server can also be a Active Directory server as it consumes very less resources.

 

Couple of more differences between SharePoint Farm and SharePoint standalone are:
1. Using separate account to connect to SQL server\SharePoint server
2. Using other accounts to manage a lot of services such as: Excel service, Performance Point, setup reverse proxy, setup load balancing.
3. Allow multiple SharePoint servers join into this farm to improve availability.
4. Multiple SharePoint servers can host Central Administration, Search Index, Search query, Web Application, etc for better performance.

What is a Web Application in SharePoint?

Web Applications are one of the very important and bit what confusing topic in SharePoint. Let me try to simplify the same. If you have worked on IIS, we create IIS site which are the actual URL of IIS site. You specify hostheader and port number while creating a IIS site. We then use the same URL with port number to browse our IIS site(e.g. http://itfreesupport.com:8081 or http://computername:80). We create a Web Application from SharePoint central admin which creates sites in IIS so we can say that SharePoint Web Applications are IIS sites but managed and created from SharePoint Central Admin.

 

Each Web Application created in SharePoint central admin is associated with a IIS site. We cannot have multiple web Application for one IIS site but we can create upto 5 IIS sites for one Web application(using Extend Web Application feature). This means we can browse same content from different URL’s using different IIS sites\web.config files.

 

Microsoft support upto 20 Web Application in a SharePoint farm but we can create more then 20 Web applications.

 

Every Web Application will have minimum 1 content database but there is not hard core limit of databases a Web Application can have. Microsoft supports upto 500 content databases in a SharePoint farm so technically you can have upto 500 content databases for single web application.

 

On your SharePoint server under services on server, if you have “Microsoft SharePoint Foundation web Application” service running\started, it states this server a WFE(Web front end) server. End users will access your SharePoint sites and services through these WFE servers.

 

Another very important feature of Web Application is authentication method for SharePoint site. We set authentication method\type(Claims authentication, NTLM authentication, Anonymous authentication, etc) at Web Application level. As discussed already you can have 5 IIS site(extended web application) for a single web application which means you can have 5 different types of authentication for same web application.

 

We can create Web Application using Powershell, command prompt(cmd) or through SharePoint Central Admin.

To create a new Web Application through powershell using powershell command:
$ap = New-SPAuthenticationProvider
New-SPWebApplication -Name “Itfreesupport” -Port 80 -HostHeader “itfreesupport.com” -URL “http://itfreesupport.com” -ApplicationPool “AppPool” -ApplicationPoolAccount (Get-SPManagedAccount “domain\user”) -AuthenticationProvider $ap

 

To create a new Web Application through stsadm command follow below:
stsadm -o extendvs -url http://itfreesupport.com -ownerlogin domain\user -owneremail “user@itfreesupport.com”

 

To create a new Web Application through central admin follow below:
Open SharePoint Central Admin > Select “Application management” > Select “Manage Web Application” > Select “New” on top ribbon > Complete the details e.g. port number, host header url, etc and click OK

PSconfig wizard fails after you install any update on SharePoint server

Hi Friends,

Recently I faced issue while updating SharePoint 2010 sp1 on servers. Installation of SharePoint 2013 SP1 didn’t caused any issue but when I try to run PSconfig wizard to update SharePoint databases, site features, etc, it stopped with below errors.

 

Environment : SharePoint 2010 standalone environment

 

ULS Logs:

Troubleshooting steps tried:
To resolve the issue I tried to run below command, but it did not help:
PSCONFIG -cmd upgrade -inplace b2b -wait -force

Confirmed that there was no password change in SharePoint farm, No issues related to content databases. Checked permission for the farm account on SQL server and SharePoint server.

User Account Control (UAC) was enabled on server to disabled it so disabled it. Tried to reboot SharePoint machine and disabled Firewall.

 

Resolution:
After some research I found that configuration database was locked which caused this issue. To resolve the issue I executed below command in powershell:

stsadm -o setproperty -pn “command-line-upgrade-running” -pv No

Then tired to refresh sharePoint by running below command:
IISreset
net stop sptimerv4
net start sptimerv4

Now when I try to run PSconfig wizard from PowerShell, it completed without any issue:
PSCONFIG -cmd upgrade -inplace b2b -wait -force

Hope this will help you in case you face any similar issue.

Access SQL server database of any version of SharePoint Standalone farm

I assume you know if we want to install SharePoint in a Workgroup environment, the only recommended Microsoft solution is to install SharePoint standalone server. Here SQL server embedded edition is installed with SharePoint server and SharePoint databases are created on this Embedded SQL server.

 

Normally we don’t perform any task on these SQL databases but incase if you want to access sharepoint databases for backup, troubleshoot, etc, you need to install SQL server management studio to achieve the same.

 

  1. Install SQL server Management studio. You can download the management studio from below link:
    http://www.microsoft.com/en-in/download/confirmation.aspx?id=29062
    0226

  2. Once installation is completed, open SQL Studio management studio
    0230

Once We have management studio installed, you can either use below registry value or servername\sharepoint to access database. Make sure you use SharePoint farm account when you connect to SQL server.

  1. Go to below registry path:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL10_50.SHAREPOINT\MSSQLServer\SuperSocketNetLib\Np

0231
2. Use the value in key “PipeName” to connect to SharePoint database server. As discussed above you can also use servername\sharepoint to connect to SQL instance
0232

Note: You need to install SQL server management studio on SharePoint server. You cannot remote connect to this SQL instance. Do not manually modify any SharePoint database, if modified, your farm\database would be unsupported

 

Applies to all version of SharePoint servers

Configure a SharePoint server in non domain(Workgroup) environment

Hi All,

Lets try to configure a SharePoint farm in a workgroup environment. Normally if we have to configure a SharePoint on a Workgroup environment only option available for us is Standalone environment. Now lets us try to understand how we can configure a SharePoint farm environment in a Workgroup environment. We need to run below powershell commands. Make sure you update passphase and SQL server name in below powershell. We have SharePoint and SQL installed on same machine. Make sure account used during FarmAccount does have access to SQL server.

$FarmAccount = Get-Credential
$PassPhrase = “FarmPassphrase”
$FarmPassphrase = (ConvertTo-SecureString $PassPhrase -AsPlainText -force)
$FarmConfigDatabase = “Wss_config_2”
$AdminContentDatabase = “SPFarm_Admin_ContentDB_2”
$CentralAdminPort = 8080
New-SPConfigurationDatabase -DatabaseServer (SQLservername) -DatabaseName $FarmConfigDatabase -AdministrationContentDatabaseName $AdminContentDatabase -Passphrase $FarmPassphrase -FarmCredentials $FarmAccount

Now let’s move a steps ahead and try to use different server for SharePoint and SQL server. Here we created a SQL user account and updated credentials in dbcredential.
$dbcredential = New-Object –typename System.Management.Automation.PSCredential –argumentlist “SQLuser”, (ConvertTo-secureString “SQLpassword” –AsPlainText –Force)
$PassPhrase = “FarmPassphrase”
$FarmPassphrase = (ConvertTo-SecureString $PassPhrase -AsPlainText -force)
$FarmConfigDatabase = “Wss_config”
$AdminContentDatabase = “SPFarm_Admin_ContentDB”
$CentralAdminPort = 8080
$FarmAccount = Get-Credential
New-SPConfigurationDatabase -DatabaseServer “SQLservername” -DatabaseName $FarmConfigDatabase -AdministrationContentDatabaseName $AdminContentDatabase -Passphrase $FarmPassphrase -FarmCredentials $FarmAccount -DatabaseCredentials $dbcredential

0227

0228

Note: We still cannot create a Multiple SharePoint server farm in Workgroup environment. Using above script you can connect only 1 SharePoint server with a SQL server.

This script works for both SharePoint 2010 and SharePoint 2013
