Hdr-Ind： 该值总是E，表示是extract process创建，如果为其他属性，则表示不可用。
UndoFlag：该属性正常值为0，当为1时则表示先前已经成功的记录进行撤销操作。
这里我不清楚是不是指这种情况：例如一个大事务未commit的情况，数据已经写入
到redo中，而ogg是读取redo进行同步的，在ogg抽取数据以后这个事务又被rollback了。
RecLength：record buffer长度，单位是bytes
IOType：表示操作类型，该属性有如下几种值：
3 - Delete
5 - Insert
10 - Update(full record)
15 - Update(compressed record)
TransInd：事务记录标志，有如下4种可能属性；
x00 - start of transaction
x01 - middle of transaction
x02 - end of transaction
x03 - only record in transaction
SyskeyLen：system key长度。如果system key存在，其第一个bytes表示system key记录，否则该值为0.
AuditRBA：事务record commit地址，同一个事务中，该值均相同。goldengate通过auditRBA+IO Time来确定
一个事务，其值是唯一的。
Continued：该属性有两种值：Y和N，用来定义数据片大大小，通常lob，clob或varchar类型，该值是Y，否则是N。
Partition：该属性是goldengate内部使用的一个标示，并不是指os或数据库层面的逻辑分区和物理分区。windows和unix
平台下，该属性值总是为4。
对于Nonstop的记录，该属性的值取决于如下两个方面：
1)存在Bulk IO操作的情况下，该值表示源端分区已经完成的bulk IO操作的数量。其取值范围为0~15.
2)对于其他非bulk io操作的nonstop record情况下，该属性取值通常为0或4. 为4的情况，表示该数据为
FiledComp record格式 (compress存储格式)。
BeforeAfter： 对于update操作，表示该数据是before image还是after image。对于insert操作，总是after images，
而delete操作总是before images。
IO Time：记录提交时间，同一个事务内的所有记录，该属性值都是相同的，为GMT格式。
OrigNode：Nonstop情况下，表示extract数据抽取端的节点号，整个cluster内，每个节点的节点号都是唯一的。
该属性取值范围是0~255. 除nonstop之外的其他情况，该属性值为0.
FormatType：表示数据是从事务日志读取还是直接从数据库中获取的。取值为F和R，F表示fetched from database。
R表示readable in transaction log。
Incomplete：该属性值从10.4版本就已经废弃了，是向前兼容保留的。
AuditPos： 标示extract process在transaction log中的位置。
RecCount：在windows和unix平台下，ogg处理lob时，是将其split成chunk，然后将chunk写入到file中。
recCount用来表示在读取时对chunk的合并。
对于logdump 看到的record 记录，其实iotype也就4种，3,5,10,15. 其中15表示compress record。
那么如何启用record的压缩存储呢？其实有个参数控制的，那就是auditcompress。
