On-premises data gateway June 2019 update released

On-premises data gateway June 2019 update released (version 3000.6.202).

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

  • Performance Profile based on gateway CPU
  • SAP Common Crypto library support for SAP BW Kerberos based SSO for Power BI
  • Others
    • Port test Issue resolution
    • HTTPS by default
    • Gateway usage and Performance monitoring template update
  • June version of the mashup engine

Performance Profile based on gateway CPU

Currently the gateway application utilizes resources on your gateway machine based on preset configurations. Using this feature, the application can now scale to use more resources or less depending on the system CPU.

To allow the gateway to scale based on CPU, this configuration “MashupDisableContainerAutoConfig” would need to be “False”. When this is done, the following configurations are adjusted based on the gateway CPU.

The configurations in this section refer to containers and Working Sets. Most queries use mashup containers to execute. So, the number of mashup containers determine the number of queries which can be executed parallelly. A working set defines the memory allocated to each container. These configurations would be available in the Microsoft.PowerBI.DataMovement.Pipeline.GatewayCore.dll.config file in the “\Program Files\On-premises data gateway” folder

  • MashupDefaultPoolContainerMaxCount: Maximum container count used for Power BI Refresh, AAS and others
  • MashupDQPoolContainerMaxCount: Maximum container count for Power BI Direct Query
  • MashupDQPoolContainerMaxWorkingSetInMB: Maximum working set size for Power BI Direct Query
  • MashupTestConnectionPoolContainerMaxInstanceCount: Maximum container count for test connection
  • MashupTestConnectionPoolContainerMaxWorkingSetInMB: Maximum working set size for test connection
  • MashupAzureConnectorsCachingPoolContainerMaxCount: Maximum container count for LogicApps, PowerApps, Flow
  • MashupAzureConnectorsCachingPoolContainerMaxWorkingSetInMB: Maximum working set size for LogicApps, PowerApps, Flow

Note: This feature will automatically be mplemented with the install or update of the June gateway if there have been no prior manual changes to the above configurations. In cases, where these configurations have been updated manually, to use this feature,  you would need to explicitly set this configuration “MashupDisableContainerAutoConfig” to “False”.

SAP Common Crypto library support for SAP BW Kerberos based SSO in Power BI

Kerberos based SSO for SAP BW in Power BI currently supports gsskrb5. Unfortunately gsskrb5 is no longer supported by SAP. With the June gateway release, we are introducing support for the SAP common crypto library for Kerberos based SSO for SAP BW

Others

  • Port test Issue resolution: The port test on the On-premises data gateway application used to fail you were using a proxy. This issue has now been fixed.
  • HTTPS by default –Starting with the June Gateway release, new installs (not updates) will default to HTTPS instead of TCP based on recommendations by the Azure Service Bus. If the gateway cannot connect using HTTPS, it will fall back to TCP/IP.
  • Gateway usage and Performance monitoring template update –In this release, we fixed a couple of issues which caused the csv format of log files to be invalid. The issues are:
    • Numerical columns having commas
    • The error type with a line break

June 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 June 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.
