db2pdlog查看日志的问题

请教个问题：db2pdlog在哪个版本有啊？我的版本如下：
[db2inst1@localhost SQLOGDIR]$ db2level
DB21085I  Instance "db2inst1" uses "32" bits and DB2 code release "SQL08022"
with level identifier "03030106".
Informational tokens are "DB2 v8.1.2.88", "s050422", "MI00117", and FixPak "9".
Product is installed at "/opt/IBM/db2/V8.1".
运行db2pdlog，报没有这个指令：
db2inst1@localhost ~]$ which db2pdlog
/usr/bin/which: no db2pdlog in (/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/home/db2inst1/sqllib/bin:/home/db2inst1/sqllib/adm:/home/db2inst1/sqllib/misc:/home/db2inst1/bin)
请问这个指令在哪个版本中有啊？怎么用它来看事务日志？
谢谢！
