front end system to the backend databases

2.4.1 DB2

Before installing DB2 on a Linux based workstation, we must ensure that our

distribution of Linux has a kernel of 2.035 or higher. We also need to have the

following packages installed:

  RPM (Red Hat package manager)

  pdksh package (public domain Korn shell)

  glibc Version 2.07 or higher

  libstdc++ Version 2.8.0

For RedHat Version 6.2 and Caldera eDesktop Version 2.4, all these

requirements were met except for the existence of the pdksh package.

2.4.1.1 Installing pdksh

The pdksh shell is used by the DB2 installer and setup scripts. It is not

normally installed as part of a server installation of Linux. Hence, we had to

install it using the

rpm

command. Figure 7 shows the command we used to

install the pdksh package from the CD ROM.

[root@bdtest3 /root]# rpm  i /mnt/cdrom/RedHat/RPMS/pdksh 5.2.14 2.i3

86.rpm

2.4.1.2 Installing DB2

There are known installation problems with DB2 6.1 at fixpack level 1.

Therefore, we chose to install DB2 v6.1 with fixpack 3 downloaded from IBM.

The steps for installation are as follows:

1. Log in as root.

2. Change the working directory to the directory where the DB2 Version 6.1

fixpack 3 code is stored.
