Installation of DB2 V11.5 software using db2_install

Before preparing to install DB2,we should check the required library files on OS.

Note: I installed DB2 on Ubuntu so used apt-get to install libraries.

Installation of library files:

To verify whether the required packages are installed on OS use below command:

 

dpkg --get-selections | grep -i <package-name> 

dpkg --add-architecture i386 #Command will enable i386 Architecture

apt-get update

We must install below library files:

apt-get -y install libaio1
apt-get -y install binutilsapt-get -y install zlib1g-dev
apt-get -y install liblogger-syslog-perl
apt-get -y install libpam0g:i386
apt-get -y install libstdc++6:i386
apt-get update

After installation of libraries few will go to /lib/x86_64-linux-gnu these files won't recognize by db2prereqcheck so we should link files from /lib/x86_64-linux-gnu/libpam.so.0 to /lib/libpam.so.0
ln -s /lib/x86_64-linux-gnu/libpam.so.0 /lib/libpam.so.0

Checking prerequisites:

./db2prereqcheck -v 11.5.0.0

groupadd -g 999 db2iadm1
groupadd -g 998 db2fadm1
groupadd -g 997 dasadm1
