ORA-12505: TNS: 监听器无法处理连接描述符中所给出的 SID

系统：unix＋oracle9.2.0.1；
本来这个系统上有两个数据库，一直运行得好好的，昨天可能有人重启了服务器，导致这个上面的监听器没有打开，可是开启监听器后连接数据库，报错：ORA-12505: TNS: 监听器无法处理连接描述符中所给出的 SID，两个都是这样，该如何解决？谢谢！

ORA-12505: TNS: 监听器无法处理连接描述符中所给出的 SID

打开你的listener.ora文件，确定两个数据库的SID设置是否正确，对应的主机ip地址是否正确，通常有人修改了listener.ora文件，在数据库重新启动去读该文件就会报错。

ORA-12505: TNS: 监听器无法处理连接描述符中所给出的 SID

我也想啊,问题是我在系统上找不到listener.ora这个文件,数据库不是我建的，因此我也没注意以前有没有这个文件.

ORA-12505: TNS: 监听器无法处理连接描述符中所给出的 SID

怎么会找不到？find一下不就行了。listener.ora一定会有的！

ORA-12505: TNS: 监听器无法处理连接描述符中所给出的 SID

我是用的find,只有这个的日志文件,没有.ora文件

ORA-12505: TNS: 监听器无法处理连接描述符中所给出的 SID

谢谢你,我重新配置了一下监听器,这次找到这个文件,可是里面没有监听这两个数据库的sid,怎么办呀?

ORA-12505: TNS: 监听器无法处理连接描述符中所给出的 SID

$ORACLE_HOME/rdbms/network

ORA-12505: TNS: 监听器无法处理连接描述符中所给出的 SID

没有这两个SID没有关系.等一会儿,数据库会自动在监听器上注册的.
或者在数据库里以SYSDBA身份运行
alter system register;
就可以了.

ORA-12505: TNS: 监听器无法处理连接描述符中所给出的 SID

ORA-12505: TNS: 监听器无法处理连接描述符中所给出的 SID

是的，重启监听器，连接数据库正常。谢谢各位！

重新启动一下监听 或者把机器名改成IP地址试下
