SQL> create pfile='/home/oracle/init.ora' from spfile;

File created.

编辑init.ora，把'/home/oracle/oradata/item/control02.ctl'去掉，而后再重启数据库

[oracle@spreader oracle]$ sqlplus /nolog

再编辑init.ora，把'/home/oracle/oradata/item/control03.ctl'去掉，而后再按照上面步骤重启数据库

ORACLE instance started.

惟一的控制文件都有问题了，FT，从新编辑init.ora文件，去掉控制文件一，而留下控制文件二和三，而后再重启数据库

SQL> startup nomount;
ORACLE instance started.

ORA-19809: limit exceeded for recovery files
ORA-00312: online log 2 thread 1: '/home/oracle/oradata/item/redo02.log'

这下能够MOUNT起来了，可是出现ORA-19809，这个简单，就是recovery files空间满了引发的，再整理下这个空间，而后alter database open 就好了。

步骤：

1 首先删除掉不必的备份，例如归档日志

2 进入RMAN整理空间 [oracle@spreader oracle]$ rman RMAN> connect target / RMAN> crosscheck archivelog all; RMAN> delete expired archivelog all;
