(安装Grid组件前的检测)

到这里，安装Grid组件的前置设置都完成了，在安装Grid之前先做一个检测，查看一下是否有配置不正确的地方，以便在安装前修改正确。先把安装介质下载到RAC节点1的/export/home/OraFile目录下，一共3个压缩文件：solaris.x64_11gR2_grid.zip、solaris.x64_11gR2_database_1of2.zip、solaris.x64_11gR2_database_2of2.zip (使用ftp的方法比较慢，我是在管理机上建立了IIS服务器，设置虚路径，把3个安装文件包括进来，再由RAC节点1下载。)

1．解压安装介质，并授权/export/home/OraFile文件夹

-bash-3.00# cd /export/home/OraFile

-bash-3.00# unzip solaris.x64_11gR2_grid.zip

-bash-3.00# unzip solaris.x64_11gR2_database_1of2.zip

-bash-3.00# unzip solaris.x64_11gR2_database_2of2.zip

-bash-3.00# chown -R oracle:oinstall /export/home/OraFile

-bash-3.00# chmod -R 775 /export/home/OraFile

2．切换用户为grid，并执行检测命令

-bash-3.00# su - grid

Sun Microsystems Inc. SunOS 5.10 Generic January 2005

-bash-3.00$ cd /export/home/OraFile/grid/

-bash-3.00$ ls

doc response rpm runInstaller stage

install rootpre.sh runcluvfy.sh sshsetup welcome.html

执行检测命令runcluvfy.sh

-bash-3.00$ ./runcluvfy.sh stage -pre crsinst -n racnode1,racnode2 -fixup -verbose

racnode1 hard 16373 16384 failed

Pre-check for cluster services setup was unsuccessful on all the nodes.

可以看到只有两项失败

Check: Soft limits for "maximum open file descriptors"

Check: Hard limits for "maximum user processes"

这两项不影响安装。
