Thank you for your reply,
This is a test environment and the query is a simple SELECT * of 5 elements that require less than second to complete that from the cli.
I don’t have a green timestamp because the error occurs during the connection verification phase.
The deploy is on a VM with RedHat 8.5 with last update using the RPM package and mariadb 10.3
SELinux is enabled, but doesn’t generate alerts or error.
I tryed the default configuration except the credential of database and connection string.
What do you mean with “deployed a JDBC connector within your environment”, i use the default mariadb connector offered by JDBC connector.
