blkno
size指出数据库项的字节数,本例中为192byte;
max指出最大的块
in-use当前正在使用的块
last-recid
27. DF Version: creation=0x9200000 compatible=0x8000000, Date 07/13/2003 14:30:51
数据文件的版本是9.2.0,兼容版本是8.0
28. DB Name "TEST1"
数据库名为"TEST1"
29. Database flags = 0x00404001
30. Controlfile Creation Timestamp 07/13/2003 14:30:52
控制文件的创建时间
31. Incmplt recovery scn: 0x0000.00000000
如果数据库进行过不完全回复,我们可以看出
32. Resetlogs scn: 0x0000.04ada796 Resetlogs Timestamp 07/13/2003 14:34:39
启用Resetlogs时的scn值和时戳,
33. Prior resetlogs scn: 0x0000.04a0b855 Prior resetlogs Timestamp 04/11/2003 09:59:18
启用Resetlogs之前的scn值和时戳
Oracle不能够应用Resetlogs之前的重做日志(redo log file)。
34. Redo Version: creation=0x9200000 compatable=0x9200000
重做日志文件的版本是9.2.0,兼容版本是8.0
35. #Data files = 12, #Online files = 12
数据库总共有12个数据文件,并且这12个文件全部处在联机(online)状态
36. Database checkpoint: Thread=1 scn: 0x0000.04b9d858
37. Threads: #Enabled=1, #Open=1, Head=1, Tail=1

39. Max log members = 3, Max data members = 1
数据库允许每个日志组最多有3个log member;
Oracle目前还不支持数据文件的多路复用,因此,Max data members的值为1,这个条目是为以后的版本升级而预留的。
40. Arch list: Head=3, Tail=3, Force scn: 0x0000.04b93016scn: 0x0000.04b9d857
请注意Force scn,凡是开始scn小于Force scn的重做都被归档。强制scn是所有重做都被归档的scn。
41. Controlfile Checkpointed at scn: 0x0000.04b9d85a 05/14/2004 08:37:00

低速缓存rba(recovery block address)指出了在实例回复或者崩溃恢复中,需要恢复的重做开始值(即,重做日志文件中的一个块地址);
on disk rba是磁盘上的最高的重做值,在进行实力恢复应用重做的时候必须达到这个值。如果on disk rba
50. on disk scn: 0x0000.04b9f6e2 05/14/2004 15:06:42
on disk scn是on disk rba处的scn值
51. resetlogs scn: 0x0000.04ada796 07/13/2003 14:34:39
启用Resetlogs时的scn值和时戳,和数据库项中的相应条目是一致的
