Yes, this is a new background process for Oracle 9i. This process is the Coordinator Job Queue process. It handles automated jobs submitted with the DBMS_JOBS package. It will spawn Jnnn processes to actually run the submitted job. If you are not using DBMS_JOBS, then you can stop this process from starting by setting JOB_QUEUE_PROCESSES=0 in your initialization file or by the ALTER SYSTEM command.
