I have configured the JDBC provider for MySQL with the connector - and then rebooted cluster - and then configured jdbc data source - following which i have rebooted cluster again - and then tested the data source - but resulted in error below.

Any thoughts on what could I be missing ?

Error
"Communications link failure. The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server. DSRA0010E."

For JDBC provider, I'm using "com.mysql.cj.jdbc.MysqlXADataSource" as classname.
And the JAR file "mysql-connector-java-8.0.26.jar" downloaded from MySQL website.
