DB2 Universal Database Version 8.2 for Linux HOWTO
Prev		Next

6. Installing DB2 Version 8.2 on Red Hat Enterprise Linux (RHEL) 4

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 2.6.9-5.0.5 EL kernel (April 20, 2005).

6.1. Pre-installation notes

The pdksh package required for a multiple-partition environment setup is installed by default on Red Hat Enterprise Linux 4.

The java-1.4.2-gcj-compat Java package is installed by default, but 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 4 completed successfully, with no problems getting the GUI installer or tools working, and no errors during the install. This smooth installation isn't surprising, given that RHEL 4 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:
db2set DB2LINUXAIO=TRUE
