Installing IBM Db2 v12.1 on Red Hat Enterprise Linux 9.5 (Plow)
In this article, I'm installing IBM Db2 12.1 on Red Hat Enterprise 9.5.
Db2 Community Edition is refreshed and updated for free at major release milestones, but does not come with enterprise-level support. However, there is a robust online community where you can post questions and learn from peers. Community support is available through the IBM Db2
Db2 Community Edition can be downloaded from the IBM Db2 website
We create an user called db2inst1 and a group called dba as root.
groupadd dba
useradd -d /home/db2inst1 -g dba -s /bin/bash db2inst1We unzip and extract all Db2 installation files
tar xzf v12.1.1_linuxx64_server_dec.tar.gzA new folder called server_dec is created
cd server_dec/redhat@server:/home/redhat/software/server_dec>
