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。

LOG FILE #1写满后，会切换到forward: 2，即切换到LOG FILE #2，这一点可以通过LOG FILE #1的Next scn: 0x0000.04b9870a等于LOG FILE #2的Low scn: 0x0000.04b9870a
85. siz: 0xf000 seq: 0x0000001e hws: 0x6 bsz: 512 nab: 0x15b flg: 0x1 dup: 1

日志发生切换时会分配一个低scn和一个高scn，低scn就是上一个日志的高scn的值，而高scn则设置为无穷大，直到切换到下一个日志文件时，再将当前日志的高scn设置为下一个日志文件的低scn，将下一个日志文件的高scn设置为无穷大。
88. Next scn: 0x0000.04b9870a 05/13/2004 19:43:45
日志发生切换后，高scn就从无穷大该为Next scn（下一个scn）的值，该值将作为切换后的日志文件的低scn

由于系统表空间的数据文件永远不能脱机，所以系统数据文件的脱机scn应该为0x0000.00000000
猜想，这里的Offline scn表示数据库上一次正常关闭时数据文件的检查点scn；
这里的Online Checkpointed at scn表示数据库本次打开时的数据文件的检查点scn
