Proxy creation failed. Unable to get the application proxy.

I have publishing the external content type via SharePoint Designer and it’s been successfully displayed in the Central Administration too but while adding the list on the site; it’s throwing an error as follows

Error Message:

Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Microsoft SharePoint Foundation-compatible HTML editor such as Microsoft SharePoint Designer. If the problem persists, contact your Web server administrator.

I checked the logs and found the following traces:

Proxy creation failed. Unable to get the application proxy

Error while executing web part: Microsoft.BusinessData.Infrastructure.BdcException: The shim execution failed unexpectedly - Unable to obtain the application proxy for the context.. ---> Microsoft.Office.SecureStoreService.Server.SecureStoreServiceException: Unable to obtain the application proxy for the context.     at Microsoft.Office.SecureStoreService.Server.SecureStoreProvider.get_Proxy()     at Microsoft.Office.SecureStoreService.Server.SecureStoreProvider.GetRestrictedCredentials(String appId)     at Microsoft.SharePoint.BusinessData.SystemSpecific.Db.DbConnectionManager.GetConnection()     at Microsoft.SharePoint.BusinessData.SystemSpecific.Db.DbSystemUtility.ExecuteStatic(IMethodInstance methodInstance, ILobSystemInstance lobSystemInstance, Object[] args, IExecutionContext context...     c8cfe618-7d0b-4dd0-bb87-55fe239f183b

There are most probably two possible reasons for this issue as:

1.   Service connection proxy

2.   Displaying number of records in a list as there is default value: 2000

Let’s try to see the resolutions for both the reasons!

Resolution#1: (for Service connection proxy)

1.   Open the central administration

2.   Application management

3.   Service Applications

4.   Configure service application associations

5.   Check the web application in which your site exist

6.   Check the “application proxy group” column

7.   Make sure the BDC and secure store service applications check boxes are mark,

8.   If they are not then please tick the check box and click OK

Resolution#2: (for displaying number of records)

1.   Open the SharePoint 2010 management PowerShell console

2.   Type the following command: Get-SPServiceApplicationProxy

3.   You will get the list of service application along with their GUID’s

4.   Copy the BCS service application GUID and paste it in notepad

5.   Now check the existing values by using this command:

Get-SPBusinessDataCatalogThrottleConfig-Scope ThrottleType Items Database-GUID-ServiceApplicationProxy

6.   Once you know the values then you will come to know that the default value is 2000 and we need to change that! How? See below-

Get-SPBusinessDataCatalogThrottleConfig –Scope Database –ThrottleType Items –ServiceApplicationProxy $contosoServAppProxy | Set-SPBusinessDataCatalogThrottleConfig –Maximum 1000000000 –Default 500000

The Business Data Connectivity Metadata Store is currently unavailable

BDC, Everybody aware as it was there in MOSS 2007 / SharePoint 2007 but now we have BCS – Business connectivity services, one of the important features in SharePoint 2010. Whenever we need to bring external content / connect to external content types then BCS comes into picture. Today’s article is also based on one of the BCS issue which I came across and resolved it with proper analysis and troubleshooting.

Problem description:

One of our users trying to connect to ‘External content types’ by means of SharePoint Designer and facing the following error.

Error message - 1:

The Business Data Connectivity Metadata Store is currently unavailable.

Error message - 2:

There is no business data connectivity service associated with the current web context.

We haven't used the BCS before so this is the first time we came across this error so when I started exploring our farm then I noticed that one of mandatory requirement to make this functionality working is – Service Application.

Point #1: Make sure you have the BCS service application (SA) exists.

So we have created the BCS SA and check the results but same problem i.e. same error message.

Point #2: Make sure you associate this service application with the respective web applications on which you have the site collections.

How to do this? – Here are the details.

1.   Open the Central Administration

2.   Application management

3.   Service applications

4.   Configure service application associations

5.   Make sure its listed under ‘application proxies’

Point #3: BCS service application has a dependency on managed metadata so make sure the managed metadata service application already exist in your environment. If it’s not then please create it.

Point #4: Make the account that you have used for creating the BCS service application has necessary permissions on the web application database.

Point #5: Make sure the Business connectivity service is in started mode via Services on Server.

How to check this? – Here are the details.

1.   Open the central Administration

2.   System Settings

3.   Servers

4.   Manage services on Servers.

5.   Check the respective service i.e. BCS and start it if it’s in stopped status.

That’s it – the issue should be resolved now after following the above recommendations.
