Issue/Introduction

After upgrading to UIM 20.3, the discovery_server keeps turning red.

The log shows:

Environment

Release : 20.3

Component : UIM - DISCOVERY

Cause

This is caused by a badly-formatted address in the CM_NIMBUS_ROBOT database table.

Resolution

Run the following SQL query vs. the UIM backend database:

select robot_id,address from CM_NIMBUS_ROBOT;

Look through the list and see if you can find a row with an address that does not match the format of all the others (/Domain/Hub/Robot) and remove that row.

Deactivate/activate discovery_server and the error should be resolved.

Additional Information

As of UIM 20.3.1 this problem still exists, but will be resolved in a future version of discovery_server.
