Failed to connect to Oracle

Hi, Using DQ Analyser for the first time .I have oracle client in my system and i can connect to oracle through my command line and also using other client tools like sql developer.
I tried configuring jdbc and also porovided host/post etc in dialog box. But the test connection always fails with “Failed to conncet to Oracle” message

Can you please help

Hello Siva,
When the message “Failed to connect to Oracle” comes up, there should be a button “More details” on the right. Please, click on it to see the whole error log.

Kind Regards,
