When the SQL> prompt is displayed, log in to one of the database instances on the cluster-paris cluster and perform a couple log switches.
oracle (phys-paris-1)$ sqlplus '/ as sysdba' SQL> alter system switch logfile; SQL> alter system switch logfile;
If there are errors, correct them. This process might take time. You can check that the network connectivity is correct by using the following command:
oracle (phys-paris-1)$ tnsping salesdr-svc oracle (phys-newyork-1)$ tnsping sales-svc
