产品数据库安装时（Oracle11g)无法连接服务器

 

找到 listener.ora 文件，我的文件路径是F:\app\wangchao04\product\11.2.0\dbhome_1\network\admin\listener.ora

 在文件中：

# listener.ora Network Configuration File: F:\app\wangchao04\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = orcl)
(ORACLE_HOME = F:\app\wangchao04\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:F:\app\wangchao04\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = wangchao0400)(PORT = 1521))
)
)

ADR_BASE_LISTENER = F:\app\wangchao04

 将(PROGRAM = extproc) 注释掉，重启相应监听服务
