Hi,

The following error is thrown when upgraded to Hibernate 6.x, H2 DB version 2.2.224

LogLevel="WARN" txnId="" "ThreadId="main" loggerName="o.h.e.j.e.i.JdbcEnvironmentInitiator" - HHH000342: Could not obtain connection to query metadata

Looks like you’re setting an explicit database version that is simply wrong or you are connecting to the wrong database with the H2Dialect.

@beikov Correct, I debugged and found it is connecting to Oracle Database version 19c. This issue is occurring after I upgrade to Spring 3, hibernate 6. I am trying to figure out how to override the config properties with test properties from resource file. Any how, thanks for the reply.
