Prepare Installation Directory

cd ~/db2setup

Download the IBM Db2 Installer

Go to IBM’s official download page:
👉 https://www.ibm.com/products/db2

Choose the Linux x86_64 version compatible with Debian 12 and download it.

If you have a direct download link, you can use wget:

wget https://example.ibm.com/path/to/v11.5_linuxx64_server.tar.gz

Extract the archive:

tar -xvzf v11.5_linuxx64_server.tar.gz
cd server_t

Run the Installer

Start the installation wizard:

sudo ./db2setup

Follow the on-screen prompts to select your installation directory, instance name, and users.

If you want a non-interactive (silent) installation, use a response file:

sudo ./db2setup -r response_file.rsp

Create a Db2 Instance

After installation completes, create a new Db2 instance:

sudo /opt/ibm/db2/V11.5/instance/db2icrt -u db2inst1 db2inst1

Switch to the instance user and start the service:

sudo su - db2inst1
db2start

Confirm the instance is active:

db2 get instance

Verify and Test the Setup

Launch the Db2 Command Line Processor (CLP):

db2

Then create a sample database to verify everything works:

CREATE DATABASE testdb;
CONNECT TO testdb;

If the connection is successful, your installation is complete.

Enable Auto Start on Boot

To make Db2 start automatically with the system:

sudo systemctl enable db2fmcd
sudo systemctl start db2fmcd

Secure the Database Environment

For production use, secure your setup by:

• Changing default passwords for instance users

• Restricting access to Db2 directories

• Configuring SSL for encrypted connections

Installing IBM Db2 on Debian 12 delivers a reliable and scalable environment for managing structured data. With its advanced optimization, stability, and compatibility with Linux systems, Db2 remains a top choice for enterprises and developers alike.
