但是過一會lsnrctl status發現監聽起來了。
[root@max2 ~]# srvctl start listener -n max2

查詢資料發現是由於在root用戶使用srvctl命令導致/var/tmp/.oracle或者/tmp/.oracle文件屬主發生變化導致的。
[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
這些文件均是 socket 文件， 且s#11521.1 中的11521 為進程號，經查證是監聽的進程號
那么這些scoket 是用來干嘛的呢？
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.
就是說：這些socket 文被用作本地客戶端使用進程間通信協議（ipc）和不同的oracle的進程通信，而這些進程包括：tns 監聽，css ，crs，evm 守護進程；甚至數據庫和asm 實例。這些socket 由‘主動監聽’的進程創建。在這里oracle tns listener 創建這些socket 文件主要使用用作pmon 和 tnslsnr 通信從報錯信息里就可以看出問題.
chown -R grid：oinstall /var/tmp/.oracle
使用grid用戶srvctl start listener -n max2，正常。
所以平時操作集群建議使用grid用戶，不要使用root用戶。
