Db2 Install on Redhat Linux

These are the steps I follow when I set up a Red Hat Linux and DB2 server for development use. I'm still new to the DB2 world, so this document is quite sparse. This details the installation of DB2 Version 9.

The main sources I used to create this document were DB2 9 for Linux, UNIX and Windows Manuals and this one.

Red Hat Install Modifications

During the Linux install, I chose the following partition structures and sizes:

swap  2098
/     2016
/usr  3016
/var  2016
/home 3016
/tmp  1024
/opt  2016
/opt/IBM fill rest of disk (at least 20GB)
    

Prerequisite File Modifications

Once the Linux install is complete, it's time to check and modify the prerequisites, run the following to check if these packages have been installed:

rpm -q libgcc compat-db libgcc compat-db libaio firefox pdksh

If you're installing 64bit, and get an error mentioning a missing libstdc++.so.5 library, then you need to install compat-libstdc++-33-3.2.3-47.3.x86_64.rpm

Installing DB2

If you are running this remotely, make sure that you have an x-server installed, and are using "X11 forward" with ssh.

Download the DB2 install.

I usually copy the downloaded file into the following folder: /opt/IBM/install

Untar the file:

tar -xvf DB2_Enterprise_Svr_Ed_Linux_x86-64.tar
    

This will create all the relevant files and directories. To start the install, run:

./db2setup &
