集群数据库软件均已安装完毕，现在想从NBU上还原数据库，但在还原控制文件报错

起初在网上查了很多，都没有给出明确的方向，但是将参数文件的路劲由asm改为本地的话就可以了，这时问题应该出现在存储上

后台日志一大堆报错，这时很明显是权限问题了。
上网搜寻一下总结的原因如下：
Cause：
经研究发现，这跟$ORACLE_HOME/bin/oracle这个文件的属性有关系：
在安装oracle soft之后：
$ORACLE_HOME/bin/oracle文件属性权限为oracle:oninstall 751(-rwxr-x--x)
在用安装ASM建库(DBCA)时：
此文件属性会自动被修改为oracle:asmadmin 6751(-rwsr-s--x)
--在PSU apply之后：
--此文件属性又被自动被修改为oracle:oinstall751(-rwxr-x--x)
Solution:
chown oracle:asmadmin $ORACLE_HOME/bin/oracle
chmod 6751 $ORACLE_HOME/bin/oracle
