Hi,
Did you see  ojdbc6 installed completely in module view? Can you successfully connect your Oracle DB through client without using talend tool?
What does your J AVA_HOME look like?
Here is a related forum about this issue:https://community.talend.com/t5/Installing-and-Upgrading/resolved-connection-failure-you-must-change....
Best regards

Hi Sabrina,
Yes, you are correct. I am facing the same problem as per blog suggested by you.
I already went through that. But didnt get any solution.   
I am able to see ojdbc6.jar and ojdbc7.jar installed.
Please find attached herewith.

Could you please let me know more about JAVA_PATH? Do I need to set the path where my JRE is installed or else?
Dont know much about this. 
Connection details are as following:

Hi Sabrina,
I am able to connect successfully to Oracle 11g Database.
I have followed: https://help.talend.com/search/all?query=Installing+external+modules&content-lang=en
I have Copied ojdbc6.jar file in location: <Open Studio Installation path>\workspace\.Java\lib 
Thanks for your guidance
