Headshot of article author Arthi Ramasubramanian Iyer

We are happy to announce that we have just released the July update for the On-premises data gateway (version 3000.7.149).


Note: The latest July build number is now 3000.7.149(was previously 3000.7.147). This latest release, includes an updated version of the Mashup Engine.

Here are some of the things that we would like to highlight with this month’s release:

  • .Net Framework Update
  • Encrypted Connection – Bug Fix
  • July version of the mashup engine

.Net Framework Update

Update:  the .NET 4.7.2 framework for gateway was not implemented with the July release. We will be implementing it at a later time.

We are using .NET 4.7.2 framework for gateways July 2019 version or higher hence some of the operating systems we used to support may no longer be supported. More information about OS which will be supported here.

With the July 2019 version of the gateway, if you don’t have the .NET 4.7.2 framework or higher but are using a supported OS version, the gateway install will prompt the .Net framework install. Choosing not to install the .Net framework will fail the installation of the gateway.

Encrypted Connection – Bug Fix

We recently identified a bug in the gateways REST APIs- the encryptedConnection attribute in Gateways – Create Datasource and the Gateways – Update Datasource APIs is currently ignored. Today, regardless of the provided value, we always try to establish an encrypted connection first but fall back to an unencrypted option in case of a failure. This has been fixed for the following data source types with this gateway release causing a value of “Encrypted” to try only an encrypted connection and “NotEncrypted” with an unencrypted connection.

  • Impala
  • MySql
  • DB2
  • Netezza
  • PostgreSQL
  • Sybase
  • Teradata

There would be no fallback behavior. This may cause failures for APIs where this attribute value is different than what the data source supports.

July version of the mashup engine

This month’s Gateway update also includes an updated version of the Mashup Engine, which will match the one released as part of the Power BI Desktop July update This will ensure that the reports that you publish to the Power BI Service and refresh via the Gateway will go through the same query execution logic/runtime as in the latest Power BI Desktop version.

Please continue to send us feedback for what new capabilities you’d like to see in the future.
