本文介绍如何查看控制文件的内容
可以通过下面两种方法查看控制文件的内容
- 使用strings命令查看
- 使用视图v$controlfile_record_session查看
- 转储控制文件到一个文本文件，然后查看文本文件的内容
1、使用strings命令查看控制文件内容
strings <控制文件名>

使用alter database backup controlfile命令转储一个控制文件
SQL>alter database backup controlfile to trace as '/home/oracle/control.sql';
SYS@PROD11G> alter database backup controlfile to trace as '/home/oracle/control.sql';
Database altered.
SYS@PROD11G> exit
