/********分析控制文件一些命令及示例*************/
Dump Level Dump Contains
1 only the file header --文件头
2 just the file header, the database info record, and checkpoint progress records --文件头和数据库信息记录,检查点进度记录
3 all record types, but just the earliest and latest records for circular reuse record types --所有类型的记录,但仅限于可重用类型记录的最早和最新的记录
4 as above, but includes the 4 most recent records for circular reuse record types --如上，还包含可重用类型记录的最新4个记录
5 as above, but the number of circular reuse records included doubles with each level --如上,上述的2倍
For example, the following syntax could be used to get a text dump on the controlfile in the trace file of the current process showing all
the controlfile record types but only the oldest and most recent of the circular reuse records.
/****oradebug仅以sysdba运行*********/
oradebug setmypid
oradebug dump controlf 3
/*******如果无sysdba却具备alter session权限**可运行如下******/
Of course, the session must be connected AS SYSDBA to use the ORADEBUG facility. However, any session with the ALTER SESSION privilege
can use the following event syntax to take the same dump.
alter session set events 'immediate trace name controlf level 3';
/*****alter session set events 'immediate trace name controlf level 1';仅dump controlfile header*********/

1,控制文件是数据库的集中配置中心,所在的元数据全在此集中
2,控制文件中时时不离scn,它会采用心跳与datafile,redo同步
3,rba与controlfile,datafile,tablespace的关系十分密切
