我在我的 Windows 10 64 位电脑上安装了 oracle，并开始执行教程中提到的验证步骤，该教程在 oracle 网站中给出，可以在下面的链接中找到。

http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/12c/r1/Windows_DB_Install_OBE/Installing_Oracle_Db12c_Windows.html

当我尝试使用此命令连接到我的可插拔数据库时

C:\Users\Chathura>sqlplus sys/Oracle_1@orclpdb as sysdba;

它给了我以下信息

SQL*Plus: Release 12.2.0.1.0 Production on Tue Jan 30 19:34:25 2018

Copyright (c) 1982, 2016, Oracle.  All rights reserved.

ERROR:
ORA-12154: TNS:could not resolve the connect identifier specified


Enter user-name:

但是当我尝试连接到容器数据库时，它连接成功。

这就是我创建可插拔数据库的方式。

在此处输入图像描述

我阅读了有关此的文章，也尝试添加 TNS_ADMIN 系统变量，但没有一个有效。我在这里做错了什么？

您必须为您的可插拔使用服务名称，您不能使用 SID ..这仅适用于容器。

所以找出服务名称

[oracle@vbgeneric ~]$ lsnrctl status

[oracle@vbgeneric ~]$

然后连接，使用@servicename vs @SID

就我而言，那是@orcl

或者连接到您的容器，然后切换到您的 PDB

oracle@vbgeneric oracle]$ sqlplus  sys/oracle@orcl12c as sysdba

视窗 10：

不知道这是否正是你的问题，但我得到了一个非常相似的问题。在为 PDB 创建新用户后，我无法连接到数据库。这是我所做的（不知道您是否需要所有这些，但它对我有用）。

  1. 在 SQL Dev Connection 上试试这个选项：

联系

  1. 添加$ORACLE_HOME/network/admin时：
ORCLPDB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orclpdb)
    )
  )
  1. 在network/admin/sqlnet.ora文件中添加：
SQLNET.ALLOWED_LOGON_VERSION_CLIENT = 8

SQLNET.ALLOWED_LOGON_VERSION_SERVER = 8

connect to your database ( pluggable database) and make thing configuration
` 
startup mount;
ALTER SYSTEM ENABLE RESTRICTED SESSION;
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
ALTER SYSTEM SET AQ_TM_PROCESSES=0;
ALTER DATABASE OPEN;
`
and also that
`
update sys.props$ set VALUE$='WE8MSWIN1252' where NAME='NLS_CHARACTERSET';
 commit;
 shutdown immediate;
 startup;
`
after that just check your tnsnames.ora`enter code here`
