Output log of the above command:
DBI1768W Unable to modify the .profile or the .login file of
user db2inst1.
Explanation: DB2 has failed to modify the .profile file or the
.login file of this user. These files may not exist, or you may
not have write permission to them. Without the modification you
need to set your environment manually each time when you log in
as this user to use DB2.
User Response: Add the following line to the .profile file or
the .login file:
. sqllib/db2profile to the .profile file, or
source sqllib/db2cshrc to the .login file
See the Quick Beginning Guide for more details on how to set the
DB2 environment automatically.

1.su - db2inst1
db2sampl
db2 connect to sample
db2 "select * from staff where dept = 20"
db2 connect reset
have err msg but OK AFTER . sqllib/db2profile to the .profile file
5. stop
su - db2inst1 ; db2stop
su - db2as ; db2admin stop作者: 阿水 时间: 2002-08-30 17:15 标题: REDHAT 7.3 DB2 安装记录 哟作者: stevenyan 时间: 2002-09-02 10:36 标题: REDHAT 7.3 DB2 安装记录 1，在BEFORE阶段，只要装一个PDKSH.用户db2inst1/db2fenc1/db2as可以在DB2安装过程的时候创建，没有必要修改.bash_profile 。
2. DB2SYSTEM set to test 这个说明DB2是要与系统名相关的，现在的机器名为TEST.
3.第三步可以省略，（如果照我的做法） 作者: hxie 时间: 2002-10-11 10:07 标题: REDHAT 7.3 DB2 安装记录 you would run db2profile first before you startup application
DB2DIR/bin
