我有两个集装箱数据库。

SID my10，服务名为M10CDB
SID my10c，服务名为MY10CL（它是第一个服务的克隆）
这两个容器都有两个可插入的数据库，my10pdb和pdbseed。
我如何区分这两个pluggable，即. my10pdb，属于不同的容器，如果我想直接连接到他们？

它们必须具有唯一的服务名称。如果它们共享相同的服务名称，则侦听器将像对待RAC数据库一样对待它们，并随机将您连接到其中一个。
看看这些文章，它们详细描述了您的问题：

https://oracle-base.com/articles/12c/multitenant-rename-services-during-pdb-creation-12cr2
https://oracle-base.com/articles/10g/dbms_service#modify-service

使用DBMS_SERVICE在新PDB中创建新服务并删除旧服务。

CONN / AS SYSDBA
ALTER SESSION SET CONTAINER=pdb1;

BEGIN
  DBMS_SERVICE.create_service(
    service_name => 'my_new_service',
    network_name => 'my_new_service'
  );
END;
/

BEGIN
  DBMS_SERVICE.start_service(
    service_name => 'my_new_service'
  );
END;
/

BEGIN
  DBMS_SERVICE.stop_service(
    service_name => 'my_old_service'
  );
END;
/

BEGIN
  DBMS_SERVICE.delete_service(
    service_name => 'my_old_service'
  );
END;
/
