dpf创建数据库失败

刚刚弄dpf，不是很熟悉，在vmware上创建两台rhel5.4虚拟机 db2 V9.7照着这个帖子http://www.db2china.net/home/space.php?uid=27514&;do=blog&id=31383
跌跌撞撞算是安装ok了
但后续创建数据库失败
报错为：
attempt to create the database "sample" failed
SQL1229N the current transaction has been rolled back because of a system error. SQLSTATE=40504

/etc/services
db2c_db2inst1 50000/tcp
db2_db2inst1 60000/tcp
db2_db2inst1_1 60001/tcp
db2_db2inst1_2 60002/tcp
db2_db2inst1_3 60003/tcp
db2_db2inst1_END 60004/tcp

db2nodes.cfg
0 db2node1 0
1 db2node1 1
2 db2node2 0
3 db2node2 1

rsh db2node2没问题，db2_all date没问题
db2start/db2stop force都没问题

希望诸位能帮忙解答写
