Connection with SQL Server Azure

AxelF_ — Mon, 09 Dec 2013 10:53:47 GMT

Hello.

We're trying to connect Nuxeo to a SQL Server Azure instance with the wizard configuration interface.The instance is OK and we have a private client connected to it. But Nuxeo failed to connect to that SQL instance. Here the exception in logs:

[http-bio-0.0.0.0-8080-exec-1] [org.nuxeo.wizard.RouterServlet] java.sql.SQLException: I/O Error: DB server closed connection.

It works on a local instance but not on an Azure instance. Here the wizard conf:

Database Type: MS SQL Server Database Name: MyDatabase Database user: user@myAzureSqlInstance Database Server host name: myAzureSqlInstance.database.windows.net Database server port: 1433

The port is openned.

Which Nuxeo version are you using? For a number of configurations you must use the Microsoft JDBC driver instead of the provided open source one. See [NXP-10234](https

Ok we changed the connection string and we are using JDBC instead of JTDS driver. Now we have another problem

Ok we managed to make it work. As said before, we changed for the JDBC Driver, and set encrypt parameter in the connection string to false.

First, for Azure the Microsoft JDBC driver (sqljdbc4.jar) should be used as the open source jTDS driver can't manage to authenticate with Azure.

The tables user2group (and maybe group2group if you use groups of groups) are indeed created without clustered indexes. You may want to recreate them with the proper clustered index:

DROP INDEX [groupid_idx] ON [user2group];
DROP INDEX [parentgroupid_idx] ON [group2group];
CREATE CLUSTERED INDEX [groupid_idx] ON [user2group];
CREATE CLUSTERED INDEX [parentgroupid_idx] ON [group2group];

I don't know, I would need to see more detailed logs. But don't post them here but on a site like pastebin.

It's happening in the Jena code (used for relations on old Nuxeo versions and still checked for compatibility reasons in recent versions) so the tables must be some of the JENA_* tables.

Re: Connection with SQL Server Azure

AxelF_ — Fri, 13 Dec 2013 09:48:26 GMT

The problem could be that I don't have any table containing JENA in table_name. There are 153 tables.
