DB2安装完后，没有成功创建实例。。。
我安装完DB2 9.7以后（实例建为db2inst2），从root su 到db2inst2，可是回显su :Unknown id: db2inst2,我去db2 bin目录下运行db2ilist发现没有实例，于是运行：./db2icrt -a server -u db2fenc2 db2inst2，可是还是不行

DBI1131E The user ID db2inst2 is invalid.

Explanation:

An attempt to access the given user ID failed. One of the following
situations has occurred:
* This user ID does not exist on the system.
* The home directory of this user is not set up properly.
* One of the user attributes needed by DB2 is unset.
* The UID of this user is 0

User response:

Make sure a valid user ID with valid home directory, shell, primary
group and secondary group has been used. Create a new user if necessary.


这是为何，怎么解决这个问题呀？？？

[解决办法]
你一个机器安装两个版本的数据库？
最好用同一个版本，你把v9.5升到v9.7吧
