MySQL Connection Error for TDV
We connected with Tibco support to resolve this issue.

Steps:


Change jar from mysql-connector-java-8.0.11.jar to mysql-connector-java-5.1.48.jar. Place the jar file "mysql-connector-java-5.1.48.jar" in location 
"\conf\adapters\system\mysql_5_5". Then restart the TDV server.
Create a new MySql 5.5 datasource with same credentials. Open the advanced settings panel for the new datasource. Then change the connection format to "mysql://xx.xx.xx.xx:3306/DBName?useSSL=false&amp;allowPublicKeyRetrieval=true"


Connection is successful.
