CLSRSC-1003: Failed to start resource OC4J

Oracle12c GRID root.sh failed with CLSRSC-1003: Failed to start resource OC4J 

执行root脚本报错如下：

原因：

This issue was investigated in Bug 17661483 - FAILED TO START ORA.OC4J DURING ROOT.SH and was closed as not a bug.
 
Local host entries in /etc/hosts file was incorrect.

OC4J uses localhost and it should be 127.0.0.1

解决办法：

Change localhost entries in /etc/hosts to below and rerun root.sh
#::1 localhost.localdomain localhost
127.0.0.1 localhost.localdomain localhost
