Thanks Harry, you are amazing !!! you saved my day.
I would need one more help => for my knowledge, when do we use this "(SERVER = SHARED)" in tnsnames? is this for Shared server config instead of dedicate connection mode?
I presumed my DB was in shared server config as the spfile parameter shared_servers=5
