Dear Sir/Madam
We have installed the on-premise version of AppDynamics with various agents in operational environment. We decided to update the controller (not agents). During the controller update, we encountered with a problem and we had to reinstall the controller. So, the controller access key was changed. It takes much time to coordinate and update the agents in operational environment and so we have not changed the agents.
According to the link 'Change Account Access Key', we changed the new account access key (for Customer1 in single tenant mode) to the old account access key (without changing any config in agent side, including the access keys). Now, every agent is OK (e.g, app agents , db agents, etc.) but database collectors does not work. Although, database agent is registered but we can't add any database collector. I have checked the controller log and found the following exception: "dbmon config ... doesn't exist". It seems that the instructions mentioned in the link above are not enough for database agent and collector, namely some extra steps are needed.
Thanks for your attention
Best regards.

Hi @myappdy.mympco,
I did some searching for similar issues and found this.
The same errors were seen in the DB Agent and controller logs due to a couple of entries related to the DB agent being missing in the entity_relationship table.
Thanks,
Ryan, Cisco AppDynamics Community Manager
