可能这是许多人遇到的问题，前几天换了IP，导致ORACLE启动不起来。
首先，要知道一点。ORACLE使用是不能使用动态IP的，必须使用静态IP。开始-》运行输入CMD，输入命令
IPCONFIG /ALL 查询需要的信息(IPD地址，网关，DNS服务器地址)，网上邻居-》属性-》本地连接-》属性-》TCP\IP
在里面选择使用下面的IP地址，填写查询到的信息
然后使用NET CONFIGURATION ASSISTANT删除原来的LISTENER，然后重新配置一个LISTENER即可。
重启服务
使用PL/SQL DEVELOPER登陆即可。
下面来比较一下TNSNAME.ORA LISTENER.ORA前后的不同
原TNSNAMES.ORA
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
新文件
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.13)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
不同处仅在于HOST参数
员阿里的是默认的HOST
新建的是计算机IP
原LISTENER.ORA
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.1.0\Db_1)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
)
)
新LISTENER.ORA
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.1.0\Db_1)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = PC-201003270020)(PORT = 1521))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)
)
HOST参数原来的是默认LOCALHOST
新建的改成了计算机名
所以
更改IP后只需要将TNSNAMES 中的HOST改成IP地址，
LISTENER中的HOST改成计算机名即可
经验证，TNSNAMES中修改成计算机名或者是LISTENER种修改成IP均是不可行的
