我在启动监听器时遇到问题，我使用的是 Centos 6.5 和 Oracle 12cR1。

数据库已成功安装。

现在我的问题是当我启动我的监听器时，会显示以下错误：

LSNRCTL> service
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=gaurav)(PORT=1521)))
TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adapter error
TNS-00511: No listener
   Linux Error: 111: Connection refused
 Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521)))
Services Summary...
Service "tuts" has 1 instance(s).
Instance "tuts", status UNKNOWN, has 1 handler(s) for this service...
 Handler(s):
  "DEDICATED" established:0 refused:0
     LOCAL SERVER
 The command completed successfully

我的主机名是gaurav

hosts所以我在文件中创建一个条目

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
 192.168.1.1        gaurav      oracle

另外，我创建了一个 listener.ora 文件，内容如下：

LISTENER =
  (DESCRIPTION_LIST =
   (DESCRIPTION =
     (ADDRESS = (PROTOCOL = TCP)(HOST =gaurav)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

sid_list_listener=
   (sid_list=
   (sid_desc=
   (oracle-home=/home/oracle/app/oracle/product/12.1.0/dbhome_1)
   (sid_name=tuts)))

我能够 ping 我的主机gaurav。

谁能帮我解决这个问题？

我正在使用 Toad 连接我的数据库，它对我来说工作正常。但是当我尝试使用相同的凭据连接时，我收到如下所示的错误消息：

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

脚步：

  1. 打开的命令提示符
  2. 到达 SQLPLUS 的路径（C:\programs\Oracle\Ora11g\BIN）
  3. C:\programs\Oracle\Ora11g\BIN\sqlplus 用户名@schema_name

  4. 输入密码 ：

    错误：ORA-12154 TNS：无法解析指定的连接标识符

  5. 但是当我用架构的所有者打开它时，它对我有用

  6. C:\programs\Oracle\Ora11g\BIN\sqlplus schema_name@schema_name

  7. 输入密码：

  8. 连接到：............

所以，我的问题是为什么我的用户名无法连接该特定模式，而该模式的所有者可以连接。注意：我可以使用 Toad 的用户名连接到该架构，但不能使用 sqlplus

我TNSNAME.ORA在TNS_ADMIN文件夹下

请帮我解决这个问题。
