Answer 1

lsnrctl status 命令回复“监听器不支持任何服务”。有一个网络监听器正在运行，但没有被告知任何数据库。

您需要将服务添加到您的listener.ora file。像下面这样将 sid_list 添加到您的 listener.ora，然后重新启动侦听器。

 LISTENER =
 (DESCRIPTION_LIST =
  (DESCRIPTION =
   (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
   (ADDRESS = (PROTOCOL = TCP)(HOST = 169.254.52.209)(PORT = 1521))
  )
 )

SID_LIST_LISTENER =
(SID_LIST =
 (SID_DESC=
  (GLOBAL_DBNAME=edss.your.domain.here)
  (ORACLE_HOME=E:\app\Administrator\product\11.2.0\dbhome_1)
  (SID_NAME=edss)
 )
)

ADR_BASE_LISTENER = E:\app\Administrator

Answer 2

这个问题可能有多种原因：

最近，我在 Windows 7 机器上的 Oracle 11g 遇到了类似的问题。发现services.msc中，OracleOraDb11g_home1ClrAgent没有启动，启动类型设置为MANUAL。

我将启动类型改为AUTOMATIC，手动启动OracleOraDb11g_home1ClrAgent，之后就可以正常连接了。

所以基本原因是OraClrAgnt 没有运行。

其他原因可以查看this link。
