官方解释
常见案例
SBT_TAPE=”version=”X.X.X.X.X” log=xxx.log”
RESTORE CONTROLFILE FROM ‘xxx.abc’ RESTORE VALIDATE;
RESTORE DATAFILE ‘/u00/xxx’ FROM ‘xxx.abc’
一般处理方法及步骤
1、这里要注意RESTOREVALIDATE和RESTORE DATAFILE是分开来操作的，要先RESTOREVALIDATE校验成功，再来指定文件名称；
2、正确的顺序，可以先执行以下步骤，试试是否可以：
SBT_TAPE=”version=”X.X.X.X.X” log=xxx.log”
RESTORE CONTROLFILE FROM BACKUPSET;
RESTORE CONTROLFILE FROM ‘xxx.abc’ RESTORE VALIDATE;
ALTER DATABASE MOUNT;
RESTORE DATAFILE ‘/u00/xxx’ FROM ‘xxx.abc’
3、如果仍然不行，则可以尝试使用NOCACHE参数，即：
RESTORE CONTROLFILE FROM ‘xxx.abc’ NOCACHE RESTORE VALIDATE;
RESTORE DATAFILE ‘/u00/xxx’ FROM ‘xxx.abc’
