DB2 communication error occurred during START or STOP DATABASE

马儿

环境是AIX 5.3  DB2 8.1.11  是分区数据库

当我启动数据库报如下错误

2007-10-11 16:28:13     0   0   SQL6048N  A communication error occurred during START or STOP DATABASE MANAGER processing.
2007-10-11 16:28:13     1   0   SQL6048N  A communication error occurred during START or STOP DATABASE MANAGER processing.

检查db2diag.log

2007-10-11-20.12.32.074484+480 E834770A417        LEVEL: Error (OS)

通过RSH测试
$ rsh localhost echo hi
rshd: 0826-813 Permission is denied.

$db2_all echo hi

hi



请教什么问题?有什么方法可以解决???很急,有解决方法的人请给回复!!!!!!!!!,多谢

分区数据库的通讯端口启动了没有
grep /etc/services
netstat -an|grep

rsh的话 你.rhost配置文件里有没有添加相关用户
/etc/hosts也需要添加主机名
