DB2 Installation with db2_install script

Hi,

Lets get started with the installation of DB2 using "db2_install" script on LINUX and UNIX platforms. You can also install DB2 using "db2setup" which launches the GUI wizard.

1) Firstly download the image and this can be done in 2 ways:

-- From the passport advantage site where you login in with your customer ID and password. Normally this image will be GA which comes with a license.

-- From the fixpack central site 

https://www-304.ibm.com/support/docview.wss?rs=71uid=swg27007053 

You have to apply the license once you install the product since this comes with 90 day trial period. Note that you can install the complete product from a fixpack image starting V9.1

2) Use the wget command for faster download to your server.
Here is an example:  

wget http://delivery04.dhe.ibm.com/sar/CMA/IMA/02bnh/0/v9.5fp7_linuxx64_server.tar.gz

3) Unzip and Untar the downloaded image as below:
-- gunzip v9.5fp7_linuxx64_server.tar.gz
-- tar -xvf v9.5fp7_linuxx64_server.tar

4) Move to the directory where the install scripts are located by running "cd server". Now run a "ls -l" command and you will notice the following scripts:

ls -l 

total 76
drwxr-xr-x  6 db2v95 db2v95 4096 Dec  4 01:10 db2
-r-xr-xr-x  1 db2v95 db2v95 5293 Dec  4 01:09 db2_deinstall
-r-xr-xr-x  1 db2v95 db2v95 5163 Dec  4 01:08 db2_install
-r-xr-xr-x  1 db2v95 db2v95 5145 Dec  4 01:08 db2prereqcheck
-r-xr-xr-x  1 db2v95 db2v95 5145 Dec  4 01:08 db2setup
drwxr-xr-x 15 db2v95 db2v95 4096 Dec  4 01:09 doc
-r-xr-xr-x  1 db2v95 db2v95 5181 Dec  4 01:10 installFixPack

5) Root installations require root user authority. For non-root installations, you must log on with the user ID that owns the non-root installation. In my example, I did the ESE product install as root.

./db2_install -p ese

It will prompt you for Install path whether you want to keep it to the default or change it as below:

Default directory for installation of products - /opt/ibm/db2/V9.5

***********************************************************
Do you want to choose a different directory to install [yes/no] ?

Enter yes to change the path. In my case I did to the default path.

6) Once done with the install you can run the db2ls to list installed DB2 products.

Install Path        Level   Fix Pack  Special Install Number Install Date              Installer UID
------------------------------------------------------------------------------------------
/opt/ibm/db2/V9.5  9.5.0.7     7                          Fri Feb 25 19:05:05 2011 CST     0

Good Luck Everyone!!!!

Thanks
