The message says there is no listener listening for *service_name* (note my stress) jbkdata. You can't use service_name (tnsnames.ora) and sid_name (listener.ora) interchangeably, however service_name should be automatically be defined as it is an init.ora paramater.

So please fire up sql*plus '/ as sysdba' and issue show parameter service_name

Most likely you will now NOT see jbkdata.
