8. Installing DB2 Version 8.2 on SuSE Linux Enterprise (SLES) 8

8.1. Pre-installation notes

The pdksh package is installed in the default setup (required for multiple-partition and high availability installations).

Also, SLES 8 installs the IBMJava2–SDK-1.3.1 rpm package in a typical installation.

8.2. Installation notes

SuSE Linux Professional installs its own 1.3.1 Java JRE by default (the "IBMJava2-SDK-1.3.1" rpm package). During the DB2 UDB installation, this will cause a warning to be generated:

Command to be run: "/bin/rpm -ivh \ '/mnt/cdrom/db2/linux/Java-1.4/IBMJava2-SDK-1.4.1-2.0'.i386.rpm" Warning: there may be a version of this package already installed.

Since this package was supplied by SuSE Linux, it will have been installed into a different directory tree than the JDK from IBM that DB2 UDB installs. Therefore, there are 3 options you can choose to deal with this issue:

1. Uninstall the Java2-1.3.1 package before installing, using either the YaST tool, or with the command line rpm -e IBMJava2-SDK-1.3.1 command. After installation, this will leave the IBMJava2–SDK–1.4.1 package as the only Java installation on the system.

2. Leave both Java packages installed. By default, DB2 UDB will use the 1.4.1 JRE that it installs. The fact that SuSE Linux's Java package installs to a different directory means that the two packages will not conflict.

3. Remove the IBM package (either with YaST or with rpm -e IBMJava2-SDK-1.4.1) after the installation completes. Update the DB2 UDB JDK_PATH configuration parameters to use the package installed by SuSE Linux:

   db2 UPDATE DBM CFG USING JDK_PATH /usr/lib/java db2 UPDATE ADMIN CFG USING JDK_PATH /usr/lib/java

Other than that one minor issue, DB2 UDB installed cleanly and setup was problem free.
