Hi,
I just upgraded to MySQL Enterprise 8.0 and wanted to test Appdynamics again after a long time (I used it some years ago with an older version of MySQL already). So I installed the new dbagent from AppDynamics and configured it (conf/controller_info.xml). When starting (./start-dbagent), I see the following error message:
...

Any ideas? My MySQL installation has the following RPMs on CentOS 7:
[root@db appdynamics]# rpm -qa | grep mysql
mysql-commercial-server-8.0.13-1.1.el7.x86_64
mysql-commercial-test-8.0.13-1.1.el7.x86_64
mysql-connector-java-8.0.13-1.el7.noarch
mysql-commercial-client-8.0.13-1.1.el7.x86_64
mysql-commercial-devel-8.0.13-1.1.el7.x86_64
mysql-commercial-backup-8.0.13-1.1.el7.x86_64
mysql-commercial-libs-8.0.13-1.1.el7.x86_64
mysql-commercial-embedded-compat-8.0.13-1.1.el7.x86_64
mysql-commercial-common-8.0.13-1.1.el7.x86_64
mysql-commercial-libs-compat-8.0.13-1.1.el7.x86_64
Thanks for any tips

Hi Alexander,
Thanks for posting the question on the Community.
It seems that this is caused by character set conflicts between DB collector and DB.
Could you try below to solve this issue?
After this executed, could you check its working, and share the log with us?
Let me know if this helped you.
Many thanks,
Naoto
Thanks,
Naoto Yamamoto

Hi Naoto,
thanks for your help. This seemed to work. Unfortunately I get the next error message now:

Hi Alexander,
It seems that mysql connector driver version is old one, so could you replace that with the latest one by the following steps?
Thanks,
Naoto Yamamoto
