  • System Center 2019 Orchestrator UR3


This article describes the issues that have been fixed for Microsoft System Center 2019 Orchestrator. This article also contains the installation instructions for the hotfix. 

The UR6 update for Orchestrator does not include any updates for the (deprecated) Orchestrator Web Features application. 

However, UR6 update includes improvements to the new HTML5 web console and .NET 6 JSON based REST API (see migration steps and the associated blog post) that was released for 2019 customers. Migrate to the new API and console to enjoy the UR6 improvements (KB5035767_Microsoft.SystemCenter.Orchestrator.WebConsole_x64.msp and KB5035767_Microsoft.SystemCenter.Orchestrator.WebApi_x64.msp) 

Issues that are fixed 

  • OEDC.exe (Event Delivery Configuration) updated to use MSOLEDBSQL driver instead of SQLNCLI. Learn more about the drivers here.

  • Active Job list in Web console shows the complete list of all the jobs that are running.

  • Run SSH Command will not work with the latest version of Linux machines, which have newer cipher requirements. To run SSH command, download the latest binary of plink.exe from the official website (x64 version may be used). The binary should be renamed to SshClient.exe and placed at path C:\Program Files (x86)\Common Files\Microsoft System Center 2012\Orchestrator\Extensions\Support\SSH

Other Improvements and Features 

The following improvements apply only to the new Web API and Web Console of 2019: 

  • Web Console Filtering: You can now take advantage of the powerful filtering system, for enhanced experience in both the job view and instance view.

  • Initial load time of the navigation tree on the Web Console reduced with optimizations made in the API authorization cache. On large SCO instances, the navigation tree would sometimes show only a subset of entries. However, with the optimization, all the entries are rendered. Ensure to follow the steps below to reflect these changes:

    • Locate web.config file at path 'C:\Program Files\Microsoft System Center\Orchestrator\WebApi' and add timeout environment variable. 

      You may choose to increase this timeout if all runbooks and folders are still not loading properly by configuring the AuthCacheComputationTimeout parameter in web.config. 
      <environmentVariable name="AuthCacheConfig:AuthCacheComputationTimeout" value="900" />

    • Download the SQL script, open SQL Server Management Studio, connect to your Orchestrator database, and execute this script. We recommend backing up your Orchestrator database to prevent any data loss.
