建立了一个控制文件的trace文件SQL> alter database backup controlfile to trace;
从trace文件里面抽取出了重建控制文件的脚本：
CREATE CONTROLFILE REUSE DATABASE "RAC" RESETLOGS  ARCHIVELOG
    MAXLOGFILES 192
    MAXLOGMEMBERS 3
    MAXDATAFILES 1024
    MAXINSTANCES 32
    MAXLOGHISTORY 292

删除所有控制文件，模拟控制文件全部丢失，重建控制文件后

报的这个错ORA-01110: data file 1: '+DATA/rac/datafile/system.256.811989669'是什么原因，怎么解决？

你看看你的归档目录在哪里，安照报错，应该是在+data/rac/archivelog目录下，你用asmcmd到+data下边看看是否存在archivelog目录。如果没有手工创建一下，还有就是
Specify log: {<RET>=suggested | filename | AUTO | CANCEL}
+data/rac/ONLINELOG/group_1.261.811989905
你把v$log中查询到的都在这里输入下，
现在数据库打不开，说明还是需要日志回复才可以
