Reassign nodes to a new polling engine

If a new name is used for the new SolarWinds SAM server, it is added to the database as a new polling engine. All current nodes remain assigned to the old polling engine name and must be reassigned to the new polling engine.

Before you begin:

  • If you have more than one Polling Engine, you need to stop each additional Polling Engine before continuing.
  • Do not stop the SQL Service.

 

  1. Click Start > All Programs > SolarWinds Orion > Advanced Features > Orion Service Manager and stop all SolarWinds services.
  1. Click File > Exit, and then from Windows click Start > SolarWinds Orion > Database Utilities > Database Manager.
  2. Expand your SQL Server in the tree, then expand the Orion database.
    Note: By default, this database is named NetPerfMon.
  3. Right-click on the Engines table, and then click  Query Table.
  4. Click Refresh to display the table entries, select Read-Write(Results can be edited).



  5. Replace the value in the ServerName field for the old polling engine with the server name of the new polling engine. In the previous graphic, the OLD-SERVER is renamed NEW-SERVER.
    Note: It is not necessary to update the IP field. The next time the service is started, SolarWinds SAM discovers the new IP address, and the IP field is updated automatically.
  6. Delete the newly added engine from the table by clicking on the blank area to the left of the row to select it and then right-click to open a menu. Click Delete Selected Rows.
  7. Click Yes to confirm deleting the row.
    Note: The final result displays the new server name with the IP address of the old server. The next time the service starts, the IP field will be updated with the IP address of the new server.
  8. Close Database Manager.
