RMAN-00554: initialization of internal recovery manager package failed

RMAN-04005: error from target database:

ORA-01031: insufficient privileges

环境是rac双节点

这个问题解决的有点崎岖，要求如下：从其他机器可以远程上来备份恢复，且不允许使用sys用户

1、创建用户haha

2、赋予sysdba

3、报如上错误

解决：如果是rac，所有的节点都需要给该用户赋予sysdba。且密码文件要存在！

我这个问题解决了半下午，就是因为测试了所有的东西，却没注意rac的另外节点是否给该用户赋予了sysdba！

是否所有节点可查询
