oracle service name

Hi guys,

my Oracle experience is a bit short but I am trying to connect to an Oracle db to generate JIRA reports.

I can connect using the oracle SQL developer, but the PBI connection says it cant authenticate my loggin.

The oracle connection askes for Port and service name. Not PBI. Why not?

I have tried every combination of the server name, port and  service name

e.g.

      Server:port

      Server/service name

      Server\service name

all  with the same reult.

any ide why it wont authenticate?

cheers

Ian
