Re: login error

Hi,

 

I believe this is a new 4.3 installation and you might have used a username "root" in the installation.

This is a known issue and there is work under progress to fix this.

 

The workaround for now is to reinstall the Controller and not to use the username as "root" anywhere during the installation.

 

Regards,

Re: dbagent startup error - registration error

Hi, Glad that the original issue is resolved. I believe the db agent is not configured correctly in controller-info.xml to connect to Controller. Could you please check the following link? https://docs.appdynamics.com/display/PRO42/Database+Agent+Configuration+Properties Regards, Saradhi
