解决oracle 11.2的grid中安装10g database报错OUI-35000

操作系统版本是Solaris 10，安装完11.2的grid之后，安装11g的RAC database没有问题。但是在安装10g RAC database的时候，进度条到50%，总是报OUI-35000 Fatal Cluster Error的错误。

此时Banner已经disable。

用ssh node1 date和ssh node2 date检查各个节点的互信，都没有问题。但是用下面的命令检查却报错互信有问题。

./runcluvfy.sh stage -pre crsinst -n node1,node2
而根据OUI-35000 Fatal Cluster Error Encountered (Doc ID 752217.1)，设置权限/etc/services to 644并不适合solaris环境，在solaris环境中，这个文件的权限是444，但是按照文档设置成644，甚至777，都还是报错OUI-35000。

我们去找找OUI的log。这个log所在的目录，需要根据central inventory目录:

server01:inst01 > cat /var/opt/oracle/oraInst.loc
inventory_loc=/oracle_grid/app/oraInventory
inst_group=oinstall
server01:inst01 >
找到/oracle_grid/app/oraInventory目录，在/oracle_grid/app/oraInventory/logs中，可以看到：

ls –l

所以问题就是在server01上启动OUI安装的时候，会去到server02上调用/usr/local/bin/ssh，而这个文件不存在，所以在OUI中报错了。

解决方法：

ln -s /bin/ssh /usr/local/bin/ssh
