Here we go with another new issue and easy resolutions & workarounds…
This time, the issue was with Nintex workflows at the time of activating a site collection feature. Let me describe the details in step by step so that it will be easy recognize as well as understand…
Problem Description:
Problem activating Site Feature. While activating the ‘Nintex workflow 2010’ at the site collection level, we faced the following error message:
Error Message:
An unexpected error has occurred.
Troubleshoot issues with Microsoft SharePoint Foundation.
Correlation ID: XXXXX
Troubleshooting Steps:
1) Most imp regarding any exceptions: SharePoint logs (\14\logs)-specifically if we face “unexpected error”
2) Windows event logs
3) If we have a correlation id then it’s very easy to find out the exact error message
After reviewing the SP logs, this is what I found:
Exception was thrown while ensuring dependencies met for feature 'NintexWorkflow' (id: 0561d315-d5db-4736-929e-26da142812c5): Nintex.Workflow.NWFeatureActivatingException: Nintex.Workflow.NW2007DatabaseConnectionException: Failed to open a connection to the Nintex Workflow configuration database. ---> System.Data.SqlClient.SqlException: Cannot open database "NW2007WFDB" requested by the login. The login failed. Login failed for user 'Contoso\Administrator'.
What we need to target first in such conditions:
1. What exactly the app pool identity is used by that web application? Does it have sufficient rights/not?
2. The Nintex database has a role called WSS_Content_Application_Pools. This is the group that we need to add the app pool identity to
· SQL SERVER
· SharePoint_Config
· Security
· Users
· The account which is running the app pool of the web application
· Right Click-Properties
· General
· Database role membership
Resolution:
I have added this group named as WSS_Content_Application_Pools to the APP POOL identity and that it. It worked and issue has been successfully resolved…
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.
