Installing DB2 Version 8.2 on Red Hat Enterprise Linux (RHEL) 3

5. Installing DB2 Version 8.2 on Red Hat Enterprise Linux (RHEL) 3

Before proceeding, please ensure that you have read Section 3 and Section 4.

These installation notes are based on a single-partition installation using the 2.4.21–20 kernel (September 20, 2004).

5.1. Pre-installation notes

The pdksh package required for a multiple-partition environment setup is installed by default on Red Hat Enterprise Linux 3.

RHEL 3 has backported the asynchronous I/O kernel capabilities of the 2.6 kernel into their 2.4 kernel, but you will need to download and install the libaio RPM package to take advantage of this.

To check for the pdksh or libaio RPM packages, run the commands:

rpm -qi pdksh
rpm -qi libaio
If either package needs to be installed, you can add it to your system with the Red Hat up2date utility (this requires registration for a Red Hat Network account). Just run:
up2date pdksh
up2date libaio

No Java package is installed by default, so there are no conflicts with the Java 2 SDK from IBM that DB2 UDB installs.

5.2. Installation notes

The installation on Red Hat Enterprise Linux 3 completed successfully, with no problems getting the GUI tools or installer working, and no errors during the install. This smooth installation isn't surprising, given that RHEL 3 is an officially supported platform for Version 8.2

5.3. Post-installation notes

Initialize the Asynchronous I/O so DB2 UDB can take advantage of this new kernel feature. As the instance owner:

db2set DB2LINUXAIO=TRUE
