背景：安装RAC，安装GI集群管理软件时，在最后快结束时，总是报如上INS-错误
#官方文档：error 说明;字符串解析失败
INS-20802: string failed.

#解决方案：SCAN 将DNS中的SCAN记录更新为A类型，而不是CNAME类型
#原因4： DNS配置正确，但是正在使用其它的命名（nls,ldap）解决方案，SA检查还是认定使用主机名解析SCAN ip
使SA检查名称解析开关配置（Linux，Solaris和/或Linux上的/etc/nsswitch.conf） AIX上的hp-ux或/etc/netsvc.conf）并更正所有节点上的错误配置。nsswitch.conf中的示例主机： hosts：files dns nis 一旦更正，执行“ $ GRID_HOME / bin / cluvfy comp scan ”确认 请注意，在AIX上，netsvc.conf可能有如下条目： hosts =本地，绑定
#原因5： Persistent cache for nscd has incorrect information.
Solution: Engage SA to restart nscd and clear persistent cache on all nodes. Example on Linux # /sbin/service nscd restart # /usr/sbin/nscd --invalidate=hosts Once it‘s corrected, execute "$GRID_HOME/bin/cluvfy comp scan" to confirm.
What‘s the expected output when executing nslookup nslookup cluscan.us.oracle.com ..
