Issue/Introduction

Hello ! 

 

My IAM service is not starting anymore . The problem is only seen after restarting the service. Upon the initial start of the IAM Service, the service is able to start and build out the tables. However, if the service is stopped and restarted, we see the error:

I have configured IAM with  MySQL 5.7.33 on a GCP environment. 

mysql-connector-java-8.0.25.jar  was used. 

Here is the content of my log file

Environment

Release : 10.6

Component : CA Service Virtualization

Cause

MysQL version 5.7.33 and higher expects 8.0.26 connector jar but our 10.6 Keycloak doesn't support it.  Limitation with Keycloak.  

Resolution

Please downgrade to MySQL server to 5.7.20 and then use mysql-connector-java-5.1.47.jar
