以前发现Oracle服务器安装后 安装好之后可以使用 但是过了几天后 或者突然就莫名其妙的监听器启动不了

后来分析是因为计算机的名称或者IP地址被改动过 导致的

解决的办法如下：

1.找到Oracle的安装路径： 如：F:oracleora92 etworkadmin

然后找到到有两个文件 listener.ora 以及tnsnames.ora 然后使用记事本或者编辑工具打开listener.ora可以看到下面这段

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = *****)(PORT = 1521))
)
)
)

红色部分即为你的主机名称 你需要改成你现在的主机名称

*****(这儿代指数据库SID)=
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = *****)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ****(数据库SID))
)
)

INST1_HTTP =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = *****)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = SHARED)
(SERVICE_NAME = MODOSE)
(PRESENTATION = http://HRService)
)
)

修改完成后 保存推出 重新启动数据库监听即可
