JDBC DataSource throwing java.sql.SQLRecoverableException while running via testrunner.sh on Linux

Hi

I'm trying to run test scripts on Linux via testrunner.sh. I'm using Ready API 1.5.0 and have installed a floating license on Linux Machine. I've many test scripts which works without any problem on my windows machine. Transferred one of those Xml project files to linux and tried to run via testrunner.sh

Test case which do not have JDBC step or JDBC datasource works fine, but those with JDBC Data Sources are throwing "java.sql.SQLRecoverableException" ( Please see full log attached )

I've already copied ojdbc jar file(the same which I use on my windows machine) to {READY API HOME}\bin\ext

Driver : oracle.jdbc.driver.OracleDriver

DB Connection String :  jdbc:oracle:thin:${#Project#DBUser}/${#Project#DBPassword}@${#Project#DBHost}:${#Project#DBPort}/${#Project#DBServiceName}

Could any please help to trouble shoot this?

Thanks & Regards,
