9. Installing DB2 Version 8.2 on SuSE Linux Professional 9.1

9.1. Pre-installation notes

If you want to run a multiple-partition environment, you will need to install the pdksh package found on CD 4.

9.2. Installation notes

SuSE Linux Professional installs its own 1.4.2 Java JRE by default (the "java2–jre-1.4.2" 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–jre–1.4.2 package before installing, using either the YaST tool, or with command line rpm erase command. This will leave the IBMJava2–SDK 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) 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.
