TNS监听起不来的原因分析

 07.12 今天早上上班,同事小李报告说ERP上去了!

           打开后,发现,TNS-12541 TNS:no listener错误,一查发现监听程序没有启动

           可以在我未解决之前,他们已前将服务器重启,按理说这个服务自启动也应该是启动了!

           su - oracle

           passwd后

           $shutdown immediate

             正常关闭

           $startup mount

             正常启动

             数据库正常.

           $ lsnrctl 

           lsnrctl> start

          TNS-12540：TNS：internal limit restriction exceeded
          TNS-12560：TNS：procotol adapter error
          TNS-00510：Iternal limit restriction exceeded 
          Linux Error：28：space left on device

          最后一句和上次的一样哦!

          空间不足! 上次是u2/oracle/9i/network/log/文件清空.OK!

         于是/u2 目录下开始清理空间数据       重复start. 错误一样!

         期间,df -h   空间都是有剩余的!

         于是转到/u1下 也清理一下!

         *当然在中间也查了相关资料和文章.也是没有用!

          含删除监听重新建立(该动作未操作)

         也用了命令 du --max-depth=1

         删除一些资料!还是不行,就这样子一直弄到中午十二点.

         后面有一个文件,/var/spool/clientmqueue

         这个文件大的惊人!

         删除该文件夹的数据.OK! 

         lsnrctl

         lsnrctl> start

         lsnrctl> status

The command completed successfully 

          OK,启动一下ERP.OK!解决!

           发现文件大小的对监听的启动还是起了不少的作用!

          希望DBA们以后注意这种细节的问题!以最快最有效的办法解决相关问题!
