InfoPath Dev

I have an installation of DBXL 2.6 on two SharePoint 2010 servers (App and WFE). DBXL was first installed and configured to use its own Active Directory service account and then re-configured  to use the same AD service account as the SharePoint web application pool. DBXL's database was installed on a dedicated instance of SQL Server and remained unchanged until earlier today.

The servrs are hosted by a third-party who had to make a configuration change. The change was moving the SQL Server database and log files off of the C: drive and on to dedicated disks to achieve better performance. This move has broken DBXL. The errors are:

• Web hosted forms that use qRules to submit the forms to DBXL have the following error reported via the Error node:
  Action: SubmitToDbxl. Arguments: submit: SubmitDocumentToDBXL doctype: fundingForm name: 2012-10-24T08-20-29[XXXXX_XXXXX] author: XXXXX .

• When attempting to access the DBXL Administration Tool the web server responds with a HTTP 500 Internal Server Error

I am able to access the DBXL databases via SQL Server Management Studio using the SharePoint web application pool account.

What would be some additional troubleshooting and resolution steps?

DBXL's web.config file has data connection strings which connect DBXL to SQL. Those are generated during installation. It sounds like the move may have left these connection strings obsolete.

Would you be able to obtain a copy of DBXL's web.config file? (from the QdabraWebService folder on the server)

My first thought is that it is a permissions issue. The server didn't move, only the database and log files moved. However it appears SQL Server was re-installed as part of the database work:

4. <DBA> Script login with passwords have been saved in .sql file for each instance in C:\RSDBA_Move folder.
5. <DBA> Detach script that needs to be ran on each instance.

Another thought is to try re-installing DBXL and attach to existing databases.

Redacting information from the web.config file for public posting may obscure any possible issues. I'll e-mail the file to you, Ernesto.

Ernesto,

Thank you for the e-mail reply.

I am having difficulty in determining what the "new" connection string should be so that I can encrypt it. I am not able to use Visual Studio's Server Explorer to generate a connection string. This may be because there is a different problem that is preventing connections. I've checked the usual suspects and continue to investigate.

Hi Darian,

The connectionString stored in the <general> section is encrypted and was not updated.  It will need to be updated to point to the new server.

<general connectionString="jkCL9AKZIpJsJMKJgIjp9ckSlrSDDjHDRwc18BOUmKDWGjdLruO5ZU5sCs83AugOQjwMWNpAcS0flKDxABfGlzpWkfZAWzT3xM0qT9qYhB/BhyO4oalzmA==" documentPath="http://SharePoint/QdabraWebService/Documents" templatePath="http://SharePoint/QdabraWebService/Forms" bulkEditDocumentLimit="200" reshredAllErrorLimit="25">

We have a tool that will allow you to generate the encrypted connection string:

Hope this helps.

The root cause of several errors was DBXL's inability to connect to its database. This was due to a configuration change to the SQL Server.

SQL Server has been reconfigured to allow DBXL to connect, a new connection string was generated and implemented, and DBXL is now functioning.

Interestingly, a related error was the failure of the Web Parts Maintenance Page. SharePoint pages containing form web parts hosting InfoPath forms that used qRules to query DBXL were failing. It was not obvious that the DBXL problem was related as the errors were:
