但是过一会lsnrctl status发现监听起来了。

[root@max2 ~]# srvctl start listener -n max2

查询资料发现是由于在root用户使用srvctl命令导致/var/tmp/.oracle或者/tmp/.oracle文件属主发生变化导致的。

[oracle@max1 .oracle]$ ps -ef|grep 11521
grid 11521 1 0 03:01 ? 00:00:00 /g01/11g/grid/bin/tnslsnr LISTENER -inherit
oracle 13012 12634 0 03:47 pts/1 00:00:00 grep 11521

这些文件均是 socket 文件， 且s#11521.1 中的11521 为进程号，经查证是监听的进程号

那么这些scoket 是用来干嘛的呢？

ODM find：

The hidden directory  '/var/tmp/.oracle' (or /tmp/.oracle on some platforms) or its content was removed while instances & the CRS stack were up and running. Typically this directory contains a number of "special" socket files that are used by local clients to connect via the IPC protocol (sqlnet) to various Oracle processes including the TNS listener, the CSS, CRS & EVM daemons or even  database or ASM instances. These files are created when the "listening" process starts.

就是说：这些socket 文被用作本地客户端使用进程间通信协议（ipc）和不同的oracle的进程通信，而这些进程包括：tns 监听，css ，crs，evm 守护进程；甚至数据库和asm 实例。这些socket 由‘主动监听’的进程创建。在这里oracle tns listener 创建这些socket 文件主要使用用作pmon 和 tnslsnr  通信从报错信息里就可以看出问题.

chown -R grid：oinstall /var/tmp/.oracle

使用grid用户srvctl start listener -n max2，正常。

所以平时操作集群建议使用grid用户，不要使用root用户。
