Oracle 18c 监听器无法启动

Question

所以我安装了 Oracle 18C XE 并且能够连接到它。几天后回到它，我可以使用 SQLPlus 连接到它，使用 sys 作为 Sysdba，但我无法连接到 SQL Developer。

Starting the listener through services results in an error saying the OracleOraDB18Home1TNSListener service on local computer started then stopped.

lstnrctl 从管理员 cmd 行开始给出以下错误：

TNS-12545: Connect failed because target host or object does not exist

TNS-12560: TNS:protocol adapter error

TNS-00515: Connect failed because target host or object does not exist 64-bit Windows Error: 49: Unknown error

好的 - 所以我可以 ping tnsnames.ora 中列出的 IP，但我无法通过该 IP 远程登录到 1521 从 tnsnames.ora

生成的 xe 条目

XE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.82)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )

为了更好地衡量 lstnrctl 状态是：

C:\WINDOWS\system32>lsnrctl 状态

64 位的 LSNRCTL Windows：版本 18.0.0.0.0 - 2020 年 6 月 2 日生产 08:25:17

  TNS-00505: Operation timed out

 TNS-12560: TNS:protocol adapter error
  TNS-00511: No listener
   64-bit Windows Error: 2: No such file or directory

我该如何解决这个问题？我只需要在 oracle 上测试 entity framework 应用程序。

我可以看出 IP 地址是错误的，但这只是本地应用程序开发的本地安装。我可以使用 Localhost 吗？

我已经更新了 tnsnames 和 listener 如下：

listener
    DEFAULT_SERVICE_LISTENER = XE

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\app\Fraser\product.0.0\dbhomeXE)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\app\Fraser\product.0.0\dbhomeXE\bin\oraclr18.dll")
    )
  )

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



tnsnames
XE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )

LISTENER_XE =
  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))


ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

但是 SQL 开发者现在告诉 returns 'ora-12514, tns:listener does not currently know of service requested in connect descriptor'

连接属性是

username: sys as sysdba
PASSWORD: (confirmed with sql plus login)
hostname:localhost
port:1521
SID XE
Service name: XE

我使用 sid 或服务名称单选按钮得到相同的结果（sid 是 ora 12505 但它仍然引用不知道连接描述符中的 SID 的侦听器）

lsnrctl 现在是：

    C:\WINDOWS\system32>lsnrctl status

tnsnames 格式是否错误？

Answer 1

是的，如果您只打算从本地计算机连接到 XE 数据库实例，则可以使用 localhost...但是它需要重新配置 Oracle Net（侦听器）和 Oracle XE 数据库，这不是那么容易。
