Serveral service_name in a listener

Question

Good afternoon,
I need my applications to connect with the choice for the sid.
How can I configure the listener to have 1 service_name TOTO and 1 service_name TUTU that connect me to the same database.
Thanks very much for your help

Just create an entry in the client side TNSNAMES entry with the correct 'name' and point it to the same location.
TOTO =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = your_host)(PORT = your_port))
    (CONNECT_DATA =
      (SERVICE_NAME = your_service1)
TUTU =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = your_host)(PORT = your_port))
    (CONNECT_DATA =
      (SERVICE_NAME = your_service2)
  )However, if you want to make the listener list more than one SERVICE then check out the SERVICE_NAMES parameter. It is a comma separated list of service names.
ALTER SYSTEM SET SERVICE_NAMES='your_service1,your_service2';
