oracle 错误码 ORA-00119 / ORA-00130

今天启动oracle时居然报错，错误信息如下：

SQL> startup
ORA-00119: invalid specification for system parameter LOCAL_LISTENER
ORA-00130: invalid listener address '(ADDRESS=(PROTOCOL=TCP)(HOST=win)(PORT=1521))'

思路：

1）首先看看是不是服务端口问题，检查/etc/services文件。

atm-zip-office  1520/tcp                # atm zip office
atm-zip-office  1520/udp                # atm zip office
ncube-lm        1521/tcp                # nCube License Manager
ncube-lm        1521/udp                # nCube License Manager
ricardo-lm      1522/tcp                # Ricardo North America License Manager
ricardo-lm      1522/udp                # Ricardo North America License Manager
cichild-lm      1523/tcp                # cichild
cichild-lm      1523/udp                # cichild
pdap-np         1526/tcp                # Prospero Data Access Prot non-priv
pdap-np         1526/udp                # Prospero Data Access Prot non-priv
tlisrv          1527/tcp                # oracle
tlisrv          1527/udp                # oracle
coauthor        1529/udp                # oracle

发现一切正常，端口号没什么问题，为什么会连接不上呢？

2）接下来怀疑是HOST=win，是不是HOST的问题呢？查看linux的host文件，/etc/hosts。

127.0.0.1        localhost.localdomain localhost
::1        localhost6.localdomain6 localhost6
127.0.0.1        localhost.localdomain localhost
127.0.0.1        oc5603811686.ibm.com oc5603811686

发现并没有win的主机名信息，所以问题应该就出在这儿，不知到为什么win这个主机名被修改了，不管怎样，添加这个主机名应该能解决问题。

127.0.0.1        localhost.localdomain localhost
::1        localhost6.localdomain6 localhost6
127.0.0.1        localhost.localdomain localhost
127.0.0.1        oc5603811686.ibm.com oc5603811686
127.0.0.1    win

重新尝试启动oracle，正常。
