IBM DB2 database can be installed on Linux, UNIX or Window operating systems. We are going to install DB2 Version 10.1 on Red Hat Enterprise Linux Server from command interface. IBM DB2 is a next generation data platform for transactional and analytical operations.
Step 1 : Download IBM DB2 Package for Red Hat Linux from following URL. You can use IBM DB2 database for 90 days without any cost.
We have downloaded the package DB2_ESE_10_Linux_x86-64.tar.gz under /opt directory.
[root@Server opt]# ls DB2_ESE_10_Linux_x86-64.tar.gz
Step 2 : Extract IBM DB2 downloaded package as shown below.
[root@Server opt]# tar -xvzf DB2_ESE_10_Linux_x86-64.tar.gz [root@Server opt]# ls DB2_ESE_10_Linux_x86-64.tar.gz ese
Step 3 : Now install IBM DB2 Package
[root@Server opt]# cd ese [root@Server opt]# ls db2 db2ckupgrade db2_deinstall db2_install db2ls db2preregcheck db2setup ibm_im installFixPack n1pack [root@Server ese]# ./db2_install DBI1324W Support of the db2 install command is deprecated. For more information, see the DB2 Information Center.

For more information see the DB2 installation log at "/tmp/db2_install.log.12177".
Step 4 : Now check which DB2 packages are installed on your server. To check installed packages you can read log files (db2_install.log.xxxxx) under /tmp directory.

Explanation: You need DB2 HA scripts to use SA MP with the DB2 HA feature. These DB2 HA scripts are located at /usr/sbin/rsct/sapolicies/db2. The DB2 installer detects whether these DB2 HA scripts need to be installed or updated. User response: No action is required.

Optional steps: To validate your installation files, instance, and database functionality, run the Validation Tool, /opt/ibm/db2/V10.1/bin/db2val. For more information, see “db2val” in the DB2 Information Center. Open First Steps by running “db2fs” using a valid user ID such as the DB2 instance owner’s ID. You will need to have DISPLAY set and a supported web browser in the path of this user ID. Verify that you have access to the DB2 Information Center based on the choices you made during this installation. If you performed a typical or a compact installation, verify that you can access the IBM Web site using the internet. If you performed a custom installation, verify that you can access the DB2 Information Center location specified during the installation. Ensure that you have the correct license entitlements for DB2 products and features installed on this machine. Each DB2 product or feature comes with a license certificate file (also referred to as a license key) that is distributed on an Activation CD, which also includes instructions for applying the license file. If you purchased a base DB2 product, as well as, separately priced features, you might need to install more than one license certificate. The Activation CD for your product or feature can be downloaded from Passport Advantage if it is not part of the physical media pack you received from IBM. For more information about licensing, search the Information Center (http://publib.boulder.ibm.com/infocenter/db2luw/v10r1/index.jsp) using terms such as “license compliance”, “licensing” or “db2licm”.

Step 5 : Now create db2 instance and fenced user.
[db2inst1@Server ~]# id db2inst1 uid=500(db2inst1) gid=500(db2igrp1) groups=500 (db2igrp1) [db2inst1@Server ~]# id db2fenc1 uid=501(db2fenc1) gid=500(db2fgrp1) groups=500 (db2fgrp1)
Step 6 : Now Create db2 instance.
[root@Server instance]# ./db2icrt -a SERVER_ENCRYPT -p DB2_db2inst1 -s ese -u db2fenc1 db2inst1 DBI1446I The db2icrt command is running, please wait. DB2 installation is being initialized. Total number of tasks to be performed: 4 Total estimated time for all tasks to be performed: 309 second(s) Task #1 start Description: Setting default global profile registry variables Estimated time 1 second(s) Task #1 end Task #2 start Description: Initializing instance list Estimated time 5 second(s) Task #2 end Task #3 start Description: Configuring DB2 instances Estimated time 300 second(s) Task #3 end Task #4 start Description: Updating global profile registry Estimated time 3 second(s) Task #4 end The execution completed successfully. For more information see the DB2 installation log at "/tmp/db2icrt.log.48480". DBI1070I Program db2icrt completed successfully.
Step 8 : Create a Sample database.
[db2inst1@Server ~] db2 “create database sample”
Your IBM DB2 database is ready to use.
