I installed a copy of DB2 express on Ubuntu (VM on windows). I did not create instance as a part of setup in the initial stage.

Now when I go to "/opt/ibm/db2/V9.7/instance$" folder and run "./db2icrt" command it says "DBI1052E You must be root to execute this program."

So I did SU <user_id> and enter password and I believe now i am acting as root. And, if I run same command again "./db2icrt" i get following msg "The current DB2 copy was not installed by the user who is running the program."

How go I get around this issue ?

Thanks for your help!

There are several limitations in effect for non-root installations.

Limitations of non-root installations

To have a fully functional product you should install DB2 as root, following instructions in the manual.

If you did install software as root, do "su -", without any user ID supplied, because that's the only way to become root.

Hello Girish,

I made a video in Portuguese language which you can follow step by step in the command line. As I said the video was made in Portuguese, but you will be able to understand.

Thank you in advance,

does it mean that if i install db2 express-C on my PC i need to create 'root' userid first and perform all installation steps under this userid?

No, root is for Linux/UNIX only. But when install on Windows, the install userid must have Windows Adminstrator rights.

You don't create root, root creates you.

Superuser - Wikipedia, the free encyclopedia

I did root install using "su -"

Then you must be root to run instance-level commands.

Correct I have done DB2 root instal.

however the quest is why is it complaining that - "The current DB2 copy was not installed by the user who is running the program.". Dispite of me using "su -" option to start the "./db2icrt" program/script.
