示例

alter database backup controlfile to ‘+DATA/ora11g/backup/control01.ctl‘;

alter database backup controlfile to trace;

alter database backup controlfile to trace as ‘/u02/app/trace123.trc’;

 

[oracle@pc2 trace]$ pwd

/u02/app/diag/rdbms/ora11g/ora11g/trace

[oracle@pc2 trace]$ ls -tl  查看时间最近的trace文件(ora11g_ora_*.trc),其中有创建控制文件的全部命令
