Detailed Error Reports and Troubleshooting Support

The improved SQL Server user interface makes troubleshooting easier for metadata extraction and query log ingestion, as you can now have a detailed error report for both processes. The report contains a detailed error description and steps to resolve the issue. (AL-139399).

SQL Server OCF Connector: Version 1.3.8

Fixed Issues

SQL Server Connection Error Soft Deletes Cataloged Objects

In SQL Server OCF Connector, an error in the SQL server connection caused an empty stream of data, which was treated as a successful MDE and resulted in the soft deletion of all the extracted metadata.

Alation now ensures that such configuration and connection errors result in metadata extraction failure instead of an empty data stream.

Fixed Issues

Connection Test Fails When Using SSL with NTLM Authentication

Fixed an issue when the connection test failed when SSL was enabled with NTLM authentication. The test resulted in the following error:

Caused by: sun.security.validator.ValidatorException: PKIX path building failed:
unable to find valid certification path to requested target

To use SSL with NTLM, basic, or Kerberos authentication, use the following JDBC URL format:


This JDBC URI includes the following additional SSL related parameters:

  • encrypt=true

  • hostNameInCertificate=<certificate_name>

You can run the command below to verify your certificate name. In the result, check for the value after CN=. That’s the certificate name.

openssl x509 -noout -subject -in <certificate_name>.crt;
