Loading this assembly would produce a different grant set from other instances in SharePoint Designer 2010

Environment entities:

-Windows server 2008 R2

-SQL server 2008

-SharePoint Server 2010 with SP1

-Client: Windows 7 + IE7.0

Problem Description: In SharePoint designer 2010, whenever I use the “Start Approval Process” action on new or existing workflows and try to publish it, it’s throwing the following error.

Error Message#1: Loading this assembly would produce a different grant set from other instances. (Exception from HRESULT: 0x80131401)

Checked the SharePoint logs and found the following error:

Error Message#2: Errors were found when compiling the workflow. The workflow files were saved but cannot be run.

Right from the beginning Microsoft is playing a very important role in publishing knowledge base article which are very useful for the whole community.

Resolution: http://support.microsoft.com/kb/2557533

As per this article, we can increase this default value to 7000 by using the following command:

$app = get-spwebapplication http://portal.sharepoint2010.com

$app.UserDefinedWorkflowMaximumComplexity = 7000

$app.Update ()

Again the best practices are saying we need to take every step by considering the farm performance as the maximum limit is 10000 and you cannot increase more than that so it’s better if we restructure our workflows with respect to reusability.

If you have any queries/questions regarding the above mentioned information then please let me know. If you have any additional resolution or valuable inputs which would be useful for the whole SharePoint community then please share…

Thank you.

The content databases in this cluster are full. You cannot add more web sites until you change the content database web site capacity settings or add more content databases

SharePoint capacity planning plays a very vital role with respect to any farm, whether it’s a small farm, medium farm or large farm. Today I am going to share some details and troubleshooting steps regarding one issue that I faced recently.

Problem Description: we have received the following error message while creating the site collection.

Error Message: The content databases in this cluster are full. You cannot add more web sites until you change the content database web site capacity settings or add more content databases.

Troubleshoot issues with Microsoft SharePoint Foundation.

Troubleshooting done: From the above error message, 2 points comes into the picture i.e. database size and number of site collections exist in a single database.

-Based on analysis, we found out that total site collections exist are 100 and size of the database was 67GB.

-checked the managed databases section in central administration with respect to that web application under which we are trying to create a site collection. We found out that somebody has changed the maximum site collection limit to 100 and that’s why we were facing that error message.

Resolution:

Please refer the following steps to get rid of this error message:

-Central administration

-Application management

-manage databases

-select the appropriate web application from the top

-change the maximum site collection limit to 15000 and warning set to 9000.

That’s it. After this we are able to create site collections without any issues.

If you have any queries/issues regarding the above mentioned information then please let me know. I would be more than happy to help you as well as resolves your issues, Thank you.

You do not have permissions to connect to the server + Access Denied in SharePoint 2010

Problem Description:

Getting the following while launching SharePoint 2010 performance point dashboard designer and connecting to datasource.

Error Message:

Access Denied.  You do not have permissions to connect to the server.  Please contact your system administrator.

Entities used:

-SharePoint server 2010

-Performance point

-SQL Server 2008 R2

-BI template for the site collection

-IE7 + windows 7 OS

Troubleshooting done:

-Performance point service application is started or not

-performance point service is started or not

-secure store service application is started or not

-secure store service is started or not

-performance point service application is properly associated with the respective web application

-the account that we have used for configuring the performance point service application has proper rights in SQL or not

-what kind of rights user has on the specific site collection that is being used inside the dashboard designer

Resolution:

After checking all the steps and thorough analysis, we check the logs and found some traces with respect to the authentication.

We have checked the authentication part with respect to that web application and it was using claim based authentication.

As per the Microsoft theory regarding performance point services, it does not support any other authentication except windows authentication.

So conclusion is windows authentication is mandatory to make the performance point functional.

If you have any queries/questions regarding the above mentioned information then please let me know. I would be more than happy to help you as well as resolves your issues, Thank you.
