oracle监听程序无法启动

前言
    我自以为对oracle的监听这一块的知识还是比较扎实的，直到这次遇到了lsnrctl start 报错，经过我初步检查之后没有发现什么可疑之处，于是我开始认识到我的知识的不足，便开始查找资料，各种关于oracle listener的文件，博客，网站的介绍。但是让我感觉奇怪的是，我找了半天的listener启动失败的博客，竟然没有一个是符合我这种条件的，于是我开始了自解之路 ，直到我真正发现了问题的所在地，我才恍然大屋--我的监听程序没有配置监听端口。
    关于我的这个监听端口号的问题，我想一般情况下不会有第二个我了，在安装数据库的时候oracle报告了一些错误，当时我并没有在意，当我启动oracle listener的时候问题出现了于是有了我的一趟弯路之行。

成功启动

    后记
   从一开始的马虎开始，没有仔细的查看listener.ora文件，理由是：这个文件不是由我自己创建而是由 DBCA创建的，但是在后来又记起在DBCA创建数据库的时候好像报了一个错误。但是创建完数据库时，我查看了一下数据库的状态，发现是open状态也就没怎么过问了，心想估计只是一个小小的错误吧，也就没有过多的追究了。
    后来我想远程连接数据库，我就不必须的启动监听程序，于是我就lsnrctl start ，但是接下来的就让我傻眼了，监听程序竟然启动不起来。于是我看了看日志文件，也没看出个所以然来，查看trace文件，竟然这个文件不存在。我就只有，一边凭着自己的经验，一边搜索资料，自行解决监听程序启动报错的问题。
    虽然这次的错误排除确实走了不少的弯路，但是这次的收获不可否认，首先我明确了listener.ora sqlnet.ora,tnsnames.ora 这三个文件的关系，以及作用和每个文件每一行的作用。加深了我对监听的理解，以及对本地命名服务的认识。相信以后出现类似的问题，我可以在比较短的时间内解决的。其次，我确实是在这次的排错的过程中找到不少的错误，也逐一改正了过来，以后再次碰到这种问题，就不会到处跑弯路了：最后，一次小小的报错让我明白，应该对每个小小的错误引起足够的注意，以免酿成不良后果。
