修改主机IP导致的ORA-12514错误(ORACLE)
当时我遇到的情况是主机自身(CENTOS)可以进入SQLPLUS,但远程客户端就报ORA-12514。但了很多资料,一般的解决情况就是服务器的listener.ora或远程登陆机的tnsnames.ora的配置问题,但我的配置均没有问题,最后终于查到原来是修改LINUX主机IP的时候漏修了一个文件。
连接时报错:

检查listener.ora和tnsnames.ora都未发现异常:

查询了metalink,虽然上面记载了很多ORA-12514错误,但是没有发现什么有帮助的线索。
由于这个错误以前并没有出现,所以怀疑是最近修改了什么东西导致了这个问题。而启动之后做了唯一的修改就是修改了主机的IP地址。
通过ifconfig修改了主机IP地址,莫非是修改错误导致了问题,不过现在通过IP地址可以正常的登陆主机,而且tnsping也没有任何的问题:

最后检查listner的日志:

发现日志中的IP地址并没有改变,看来是修改IP的时候遗漏了什么位置。
检查HOSTS文件,发现里面的配置忘了进行修改:
# Do not remove the following line, or various programs
# that require network functionality will fail.
172.25.4.70 yangtk2.ytk-thinkpad
127.0.0.1 localhost.localdomain localhost
将hosts文件中的ip也修改为当前的IP后,问题解决。
