Question

我是oracle的新手，我已经安装了带有sql plus的oracle 10g。我昨天使用sql plus但是现在它在登录时给了我这个错误 ORA-12170：TNS：发生连接超时。我正在使用 SCOTT用户进行登录。

我正在使用这些凭据登录：

用户名：Scott

密码：tiger

host：orcl

我已经搜索了它并尝试了一些解决方案，但它不起作用：（

以下是我的配置的一些细节：

SQLNET.ORA

SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

的listener.ora

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
  (SID_NAME = PLSExtProc)
  (ORACLE_HOME = C:\oracle\product\10.2.0\db_1)
  (PROGRAM = extproc)
 )
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
  (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
  (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.9)(PORT = 1521))
)
)

的tnsnames.ora

ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.9)(PORT = 1521))
(CONNECT_DATA =
  (SERVER = DEDICATED)
  (SERVICE_NAME = orcl)
)
)

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
  (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
)
(CONNECT_DATA =
  (SID = PLSExtProc)
  (PRESENTATION = RO)
)
)

Answer 1

尝试ping 192.168.1.9。如果可行，请尝试

tnsping orcl

从命令行

。也许有防火墙会阻止您对Oracle DB的网络访问？
