第 1章   数据库服务器监听错误

1.1.1数据库监听错误

1.1.1.1 问题及现象

服务器环境为ORACLE11G RAC环境,系统启动后,监听没起来。

 TNS-12560: TNS:protocol adapter error
  TNS-00511: No listener
   Linux Error: 111: Connection refused

1.1.1.2 检查思路

 

当时同事已经检查过CRS、也尝试过使用命令启动监听等步骤。但是启动监听的时候会有以下报错

 

[oracle@RAC4 ~]$ lsnrctl start
LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 29-JUN-2015 10:51:46

居然说系统已使用,那么理所当然的就去查看1521端口和lsn进程

 

[root@RAC4 ~]# ps-ef | grep lsn

grid     52181     1  0 10:04?        00:00:11/u01/*/*/bin/tnslsnrLISTENER_SCAN1 -inherit

root    101600 100759  0 22:30 pts/0    00:00:00 grep lsn

[root@RAC4 ~]#netstat-anp | grep 1521

tcp       0     0xxx.xxx.xxx.xxx:1521          0.0.0.0:*                  LISTEN      52181/tnslsnr     (有些内容不便列出) 

 

发现1521端口和/u01/11.2.0/grid/bin/tnslsnrLISTENER_SCAN1-inherit进程存在,所以尝试杀掉此进程

 

[root@RAC4 ~]#kill -9 52181

-bash: kill:(52181) - No suchprocess

 

杀掉后发现系统提示没有这个进程,再次查询

 

 

[root@RAC4 ~]# ps-ef |grep lsn

grid    104147     1  0 23:23?        00:00:00/u01/*/*/bin/tnslsnrLISTENER_SCAN1 -inherit

root    104379 104353  0 23:28 pts/0    00:00:00 grep lsn

 

又有了,应该是父进程自动又给他启动了,查看其父进程是init进程。

 

[grid@RAC4 ~]$pstree 1

init─┬─MBADataMover───MBADataMover───MBADataMover

    ├─2*[tnslsnr───2*[{tnslsnr}]]

 

 

 

1.1.1.3 出现问题的原因

 

因为我记得在书上看到过,11G的RAC中SRVCTL可以管理监听,于是尝试使用此命令来启动监听。

 

1.1.1.4 解决方法

[grid@RAC4 ~]$srvctl start listener -n RAC4

 

[grid@RAC4~]$ exit

logout

[root@RAC4~]# su -oracle

[oracle@RAC4~]$lsnrctl status;

1.1.1.5 知识点

经过这次问题的解决,发现oracle 11G的RAC中有很多功能都通过集群命令来控制,而不能单一的通过单机管理的方法来控制集群的某些功能
