Oracle Database 12c tnsnames.ora文件

Question

我是Oracle 12c的新手。在安装步骤中，我需要在tnsnames.ora文件中添加服务orclpdb。为什么我需要添加此服务？

ORCLPDB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orclpdb)
    )
  )

Answer 1

实际上不需要任何sqlplus @ORCLPDB文件。

但是，编写sqlplus @(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=orclpdb)))比编写tnsnames.ora要简单得多。 >>> list_1 = ["1111","2222","3333","4444","5555"] >>> list_2 = ["k1 1111", "k2 2222", "k3 3333", "k4 4444", "k5 5555", "k6 6666", "k7 7777", "k8 8888" ,"k9 1111"] >>> [x for x in list_2 if not any( y in x for y in list_1)] ['k6 6666', 'k7 7777', 'k8 8888'] 提供了简单的别名，而不是使用相当复杂的全名。
