1、 # alter database backup controlfile to trace；

2、 根据日志文件可查找trace文件，日志文件如下：

Sat May 29 23:14:06 2010

alter database backup controlfile to trace

Backup controlfile written to trace file /u01/diag/rdbms/orcl/dave/trace/dave_ora_10927.trc

Completed: alter database backup controlfile to trace

3、 trace文件内容如下：

Trace file /u01/diag/rdbms/orcl/dave/trace/dave_ora_10927.trc

-- Below are two sets of SQL statements, each of which creates a new
