标题:RAC环境下删除了/var/tmp/.oracle/的临时文件,有什么后果,以及如何处理

作者:Lunar©版权所有[文章允许转载,但必须以链接方式注明源地址,否则追究法律责任.]

测试目的: 模拟RAC环境下有人误操作,删除了/var/tmp/.oracle/*下的oracle临时文件(删除Network Socket File)
测试过程:观察会有什么后果,以及如何处理。
.
测试环境:OEL 6.6 ,Oracle 11.2.0.4 Standalone(单实例使用ASM的环境)
如果是RAC,测试结论应该大体一致(机制类似)。

[root@lunarlib rootwork]# cat /etc/oracle-release 
Oracle Linux Server release 6.6

在Linux平台上,RAC或者HAS(单实例使用ASM的环境,比如standalone或者我们说的Oracle Restart)使用的Network Socket File在/var/tmp/.oracle/*文件:
(在其他平台(比如, AIX HPUX等等)Network Socket File可能在:ls -lrt /tmp/.oracle/* /tmp/.oracle 或者 /usr/tmp/.oracle)

[root@lunarlib etc]# ls -lrt /var/tmp/.oracle/*

使用crsctl stop has -f停止has,然后就可以直接删除/var/tmp/.oracle/* 下面的Network Socket File:

此时,使用crsctl stop has -f不能停止has服务:

[root@lunarlib rootwork]# crsctl stop has -f
CRS-4544: Unable to connect to OHAS
CRS-4000: Command Stop failed, or completed with errors.
[root@lunarlib rootwork]# 

reboot是比较好的选择。那么,如果主机不方便reboot,怎么办呢?
不能重启主机,咱们可以手工处理相关问题。首先,手工清理所有has的进程的网络通讯socket临时文件:

[root@lunarlib rootwork]# rm -rf /var/tmp/.oracle/*
[root@lunarlib rootwork]# ll /var/tmp/.oracle/
total 0
[root@lunarlib rootwork]# ps -ef|grep d.bin
grid      4332     1  0 18:40 ?        00:00:09 /u01/app/11.2.0.4/grid/bin/ohasd.bin reboot

grid      4594     1  0 18:42 ?        00:00:00 /u01/app/11.2.0.4/grid/bin/tnslsnr LISTENER -inherit

[root@lunarlib rootwork]# ps -ef|grep ohasd

root      4996  4305  0 19:02 pts/1    00:00:00 grep ohasd
[root@lunarlib rootwork]# crsctl status res -t
CRS-4639: Could not contact Oracle High Availability Services
CRS-4000: Command Status failed, or completed with errors.
[root@lunarlib rootwork]# 
[root@lunarlib rootwork]# crsctl stop has -f
CRS-4544: Unable to connect to OHAS
CRS-4000: Command Stop failed, or completed with errors.
[root@lunarlib rootwork]# 

这时正常的停止has的命令都不能使用了,因为进程间通讯的socket文件被我们删除了。
但是我们可以kill他们:

[root@lunarlib rootwork]# kill -9 4332 4560 4566 4591 4594 4603 4639 2882 4332
[root@lunarlib rootwork]# ps -ef|grep d.bin
root     15575  4305  0 19:04 pts/1    00:00:00 grep d.bin
[root@lunarlib rootwork]# ps -ef|grep ohasd
root     15548     1  0 19:04 ?        00:00:00 /bin/sh /etc/init.d/init.ohasd run
root     15580  4305  0 19:04 pts/1    00:00:00 grep ohasd
[root@lunarlib rootwork]# kill -9 15548
[root@lunarlib rootwork]# ps -ef|grep ohasd
root     15581     1  0 19:04 ?        00:00:00 /bin/sh /etc/init.d/init.ohasd run
root     15608  4305  0 19:04 pts/1    00:00:00 grep ohasd
[root@lunarlib rootwork]# 
[root@lunarlib rootwork]# ps -ef|grep d.bin
root     15623  4305  0 19:04 pts/1    00:00:00 grep d.bin
[root@lunarlib rootwork]# 
[root@lunarlib rootwork]# /etc/init.d/init.ohasd stop -f
[root@lunarlib rootwork]# ps -ef|grep ohasd
root     15581     1  0 19:04 ?        00:00:00 /bin/sh /etc/init.d/init.ohasd run
root     15650  4305  0 19:05 pts/1    00:00:00 grep ohasd
[root@lunarlib rootwork]# /etc/init.d/init.ohasd stop
[root@lunarlib rootwork]# ps -ef|grep ohasd
root     15581     1  0 19:04 ?        00:00:00 /bin/sh /etc/init.d/init.ohasd run
root     15672  4305  0 19:05 pts/1    00:00:00 grep ohasd
[root@lunarlib rootwork]# 

在我的测试中,has环境下,一次kill所有进程主机都没有重启(在rac环境下,kill ocssd.bin可能会引起主机重启):

[root@lunarlib rootwork]# ipcs -ma

------ Shared Memory Segments --------
key        shmid      owner      perms      bytes      nattch     status      

------ Semaphore Arrays --------

0x00000000 0          root       600        1         
0x00000000 65537      root       600        1         

------ Message Queues --------
key        msqid      owner      perms      used-bytes   messages    

[root@lunarlib rootwork]#

然后手工重启has:

[root@lunarlib rootwork]# crsctl start has
CRS-4123: Oracle High Availability Services has been started.
[root@lunarlib rootwork]# 
[root@lunarlib rootwork]# ps -ef|grep ohasd
root     15581     1  0 19:04 ?        00:00:00 /bin/sh /etc/init.d/init.ohasd run

root     15817  4520  0 19:09 pts/0    00:00:00 tail -f ohasd.log
root     15935 15908  0 19:10 pts/2    00:00:00 grep ohasd
[root@lunarlib rootwork]# ps -ef|grep d.bin

root     15937 15908  0 19:10 pts/2    00:00:00 grep d.bin
[root@lunarlib rootwork]# 

随着has的启动,它自己创建了新的网络通讯socket文件:

总结,如果RAC或者HAS下
1,在Linux平台上,Network Socket File在/var/tmp/.oracle/目录下。在其他平台,可能的目录有:/tmp/.oracle/*, /tmp/.oracle 或者 /usr/tmp/.oracle
2,如果CRS或者HAS没有启动,删除oracle临时文件(Network Socket File),在CRS重启后会自动重新创建,没有不良影响。
3,如果CRS或者HAS已经启动并正常运行中,删除oracle临时文件,不影响数据库运行,但是数据库不能正常关闭(可以abort,但是不能启动)
4,如果出现了上面的情况3,CRS不能关闭(包括使用-f选项),只能手工清理共享内存段和kill 进程。在HAS中,kill ocssd.bin进程不会造成主机重启。但是在RAC环境下kill ocssd.bin进程会造成主机重启。
5,如果完成了上面的情况4,只需要重启CRS或者HAS就可以了。
