The security validation for this page has timed out" error message when a user submits data to Windows SharePoint Services

                                       

Cause: This behavior occurs if a user submits information to the server after the security validation time-out that is set for the virtual server expires. By default, the security validation time-out value in Windows SharePoint Services is set to 30 minutes. That is, if 30 minutes pass before the user clicks Save and Close to submit data to the server, the user must reenter the data and then resubmit that data to the server.

      Workaround: Increase the security validation time-out value. To do this, follow these steps:

·        Click Start, point to All Programs, point to Administrative Tools, and then click SharePoint Central Administration.

·        Under Virtual Server Configuration on the Windows SharePoint Services Central Administration page, click Configure virtual server settings.

·        On the Virtual Server List page, click the name of the virtual server that you want to configure.

·        Under Virtual Server Management on the Virtual Server Settings page, click Virtual server general settings.

·        In the Web Page Security Validation area of the Virtual Server General Settings page, specify the number of minutes that you want to set for the security validation time-out, and then click OK.

If you click on click to 'datasheet view' .The query cannot be completed because the number of lookup columns it contains exceeds the lookup column threshold enforced by the administrator

if you click on click to 'datasheet view' .The query cannot be completed because the number of lookup columns it contains exceeds the lookup column threshold enforced by the administrator.

 Cause:  By default the limit is 8 lookups per list for users.

  Background: While using farm admin account the  error is not coming "The query cannot be completed because the number of lookup columns it contains exceeds the lookup column threshold enforced by the administrator." But while using SharePoint user account including site collection owners this " error occurs.

 Resolution:  Each new lookup column requires an additional SQL join.  As the number of joins goes up it will have a  effect on performance.  By default the limit is 8 lookups per list.  As you have seen this limit does not apply to farm admins.  You can change the limit for other users in the Resource Throttling settings of the web application in Central Administration.  But making changes to the resource limit can impact performance.

·  Go to Central admin-> Application Management > Manage Web Application.

·   In the Web Application list, select the web application you need.

· Then go to General Settings > Resource Throttling.

                     

                            

·  In the Resource Throttling window, scroll down to List View Lookup Threshold and change the value to the number that suits your needs.

                   

· Click OK.

Unable to process Create message - Profile Syncronisation in SharePoint 2010

Recently, when I am working for One of my Project, faced the issue with the user profile synchronization for SharePoint 2010.I followed the below steps to Trouble shoot the issue.

   Issue: Unable to add user properties for user profile connection. Getting “Unable to process Create message” error.

          No Error’s in the event log, ULS Logs and FIM

 Steps taken to troubleshoot the issue:

 note: Before following the steps please take a backup of your Profile and Sync DB.

           Follow the below TechNet article to Reset profile synchronization’: 

 http://technet.microsoft.com/en-us/library/ff681014.aspx

 Rebooted the APP sever after the reset and added the Farm account on Sync DB as DBO owner on SQL server.

Started the profile synchronization service on APP server.

Ensure the profile service started successfully without any errors.

Checked the User profile application and found that the profiles connection got removed automatically (Expected behavior after the Reset Sync Instance).

Created a new profile connection successfully without any error (Unable to process Create message )

 After that I am able to edit/modify/update the profile connection without any error
