There was an error retrieving data from a datasource + An entry has been added to the Windows event log of the server + Event ID-7893

Problem Description:

I have a browser enabled InfoPath form loading in a Form web Part in a webpart page with another connecting web part. When users try to open the form they get:

"An error occurred querying a data source"

Sympton-1: Occasional error when opening an InfoPath form

Sympton-2: InfoPath timeout random error first time form is loaded

Sympton-3: An error occurred querying a data source

Sympton-4: There was an error retrieving data from a datasource.

Click OK if you want to resume filling in the form.  Possibly you might want to check the form for errors.

Sympton-5: There was an error retrieving data from a datasource. An entry has been added to the Windows event log of the server.

Log ID: 7893

Troubleshooting:

Best suggestion / recommended one is check the SharePoint ULS logs and find out the exact root cause behind this error message. I also did the same and found out that it is happening because of data connection time outs.

Resolution:

The Maximum data connection timeout value you modified is used to override all data connection time out values that specified within form template code. If you are not specified the time out value within form template code, please increase the default data connection timeout in Central Administration.

-Central Administration

-General Application Settings

-Configure InfoPath Forms Services

-Increase the time out value and try again.

If you have any queries/questions based on 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.

Cannot connect to PerformancePoint Services in SharePoint 2010

Today I am going share some troubleshooting that we have performed with respect to Performance Point Service. In this article, I will try to explain on

-Performance point Service (PPS) service application (SA)

-their associations, proxy SA

-services required

-dependent services

What is Performance point Service (PPS)?

Dashboards are a fundamental component of any performance management solution, and SharePoint 2010 Performance Point Services provides a rich set of tools and services for building highly interactive dashboard experiences that can help organizations of all sizes monitor and analyze their performance.

Problem Description:

After dashboard designer is opened, I try to define a new data source by right clicking on data connections. After I chose excel services, the error message is displayed.

Error Message:

Cannot connect to PerformancePoint Services. Contact the administrator for more details.

Recommended:

I am definitely going to share my troubleshooting steps, but what i can suggest is- if you face the same error message then please check the SharePoint ULS logs for better clarity.

Troubleshooting steps:

-use firebug to analyse the traffic

-check sharepoint logs to target the exact root cause

-check the service applications and their associations i.e. proxy Sa

-make sure that the PerformancePoint Service is turned on

-make sure that the secure store service is turned on

-make sure that secure store service has been properly configured in your farm.

Resolution steps:

1-When I checked the secure store service in my farm then i came to know that it was not 100% configured. Next question definitely comes into picture as what is meant by not configured.

Please follow these steps and make sure it is properly configured:

-Central Administration

-Application management

-service applications

-secure store service

-manage

-generate a new key

-enter the passphrase

-make sure the secure store service is turned on

-unattended service account is an optional step, if you wanna configure it then you can proceed ahead.

2-make sure the performance service is turned on.

Note: make sure that performance service application is already created and in started mode.

Please follow these steps:

-Central Administration

-Application management

-manage services on server

-performance point service

-status should be in STARTED mode.

Reference:  if you want to configure performance point service application in your farm then please refer the following link for detail description:

http://technet.microsoft.com/en-us/library/ee748643(v=office.14).aspx

3-make sure that performance point service application is properly associated with the web application.

Please follow these steps if it’s not there:

Go to Central Admin > Application Management > Configure service application associations > click default.

You should see that PerformancePoint Services will be unchecked. Check that box and you should be good to go.

You can cross check whether the PerformancePoint service application is properly configured by accessing PPS sites, Dashboard designer and other PPS first class objects in Business Intelligence Center Site. Before that, ensure to activate the PPS feature in Site Settings > Site collection features.
