Khi kết nối với PDB, bạn phải sử dụng tên DỊCH VỤ.
SID chỉ dành cho cơ sở dữ liệu vùng chứa.

Service Name. When you create a PDB, Oracle automatically adds it as a service in the listener. You can confirm it by looking at the listener status:
[[email protected] trace]$ lsnrctl status

The command completed successfully
The service "pdb1" actually points to the PDB called PDB1. It's very important to note that that this is not a service name in initialization parameter of the database, as you can see from the service_names parameter of the database.

service_names string CONA
You can place that service name in an entry in the TNSNAMES.ORA file:
PDB1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = prosrv1.proligence.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PDB1)
)
)
Now you can connect to PDB1 using the connect string:
[[email protected] ~]$ sqlplus system/[email protected]
