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:
