Environment

  • UIM 23.4.6 (CU6)
  • OC 23.4.6 (CU6)

Cause

After upgrading UIM and OC, uimapi package is not automatically upgraded by running the upgrade files.  The uimapi package must be updated manually.

Resolution

Update the uimapi package by using one of the two following methods:

  • In Infrastructure Manager:
    • Find the uimapi 23.4.6 package in the UIM archive.
    • Drag/drop the package to the robots where you have deployed the uimapi package
    • A window opens so that you can 'View Distribution Progress'
    • After the package is deployed, it can be found with the correct version in the controller probe Installed Packages window.

  • In Admin Console:
    • Select a hub, and then select the Archive tab.
    • Select the inline menu button next to a package, and then select Deploy.
    • In the Hubs pane, select the check box next to a hub to select all the robots where you have deployed the uimapi package
    • The Target Robots pane updates to show the selected robots.
    • Select Deploy.
    • The page redirects to the Deployment Activity tab where you can monitor the deployment.
    • After the package has been deployed to a robot, it is displayed in the Installed Packages tab with the correct version
