Overview

If you change the name of your Orion server after an upgrade, you will notice multiple primary polling engines in the Engines table. They need to be cleared out and the nodes reassigned to the correct polling engine.

Environment

  • NPM 11.x
  • NPM 12.x

Cause 

Changing the name of a server during the upgrade caused multiple entries in the Engines table to be incorrect.

Resolution

  1. Stop all Orion Services using the Orion Service Manager.
  2. Open the Database Manager and load the default server.
  3. Navigate to the Engines table, right click and query table. At the top center window hit Execute.
  4. If you only have one Primary Polling Engine, there should only be one entry here.
  5. Enable Table editing at the top and remove the false entries.
  6. Start all Orion Services.
