6. 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).
6.1. 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.
6.2. 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
6.3. Post-installation notes
Initialize the Asynchronous I/O so DB2 UDB can take advantage of
this new kernel feature. As the instance owner:
