instance owner账户没有权限执行db2start/db2stop!

hannary

求助，我的环境不知出了什么问题，用instance owner账户执行db2stop:

-bash-3.00$ db2stop
-bash: /db2home/users/d8f9a64/sqllib/adm/db2stop: Permission denied

然后加了x权限：
-r-xr-xr-x   1 root       db2admin   2117600 Aug 21 03:53 db2stop

再执行db2stop:
-bash-3.00$ db2stop
SQL1042C  An unexpected system error occurred.  SQLSTATE=58004

下一步该怎么做呢？

是否改过db2的目录的权限？从错误提示看是写入只读权限文件时报的错。
