RHBA-2010:0491 - Bug Fix Advisory

Topic

New java-1.4.2-ibm-sap packages that comprise IBM's 1.4.2 SDK release are now
available for Red Hat Enterprise Linux Advanced Platform for SAP. These new
packages serve as enhanced replacements for the previous java-1.4.2-ibm packages
for Red Hat Enterprise Linux Advanced Platform for SAP.

Description

IBM Java releases include the IBM Java 2 Runtime Environment (JRE) and the IBM
Java 2 Software Development Kit (SDK). These packages comprise IBM's 1.4.2 Java
release:

• java-1.4.2-ibm-sap
• java-1.4.2-ibm-sap-demo
• java-1.4.2-ibm-sap-devel
• java-1.4.2-ibm-sap-javacomm
• java-1.4.2-ibm-sap-src

Important: these new java-1.4.2-ibm-sap packages (for Red Hat Enterprise Linux
Advanced Platform for SAP) serve as a replacement for the previously-released
java-1.4.2-ibm packages for Red Hat Enterprise Linux Advanced Platform for SAP.
The previous java-1.4.2-ibm packages for Red Hat Enterprise Linux for SAP, which
were released as the RHEA-2009:1195 advisory, were not able to be installed
alongside the java-1.4.2-ibm packages from the Red Hat Enterprise Linux
Supplementary channel. These new packages fix this problem so that they can be
installed alongside the java-1.4.2-ibm packages from the Red Hat Enterprise
Linux Supplementary channel.

Important: If you installed the previously-released java-1.4.2-ibm packages for
Red Hat Enterprise Linux Advanced Platform for SAP, you must manually uninstall
those packages before installing these new, replacement packages. These
replacement packages do not obsolete the previous java-1.4.2-ibm packages for
Red Hat Enterprise Linux for SAP. The benefit to installing these replacement
packages is that they may be installed alongside the java-1.4.2-ibm packages
from the Red Hat Enterprise Linux Supplementary channel, with the end result
that the "alternatives" tool can then be used to switch between the normal and
SAP-specific JVM and Java compiler (but see Important note below). This was not
possible with the previous java-1.4.2-ibm packages for Red Hat Enterprise Linux
for SAP.

Important: If you install these new java-1.4.2-ibm-sap packages alongside the
java-1.4.2-ibm packages, you can switch between them using the "alternatives"
tool as the root user. Note additionally that both of these packages will appear
in the "system-switch-java" graphical tool under the same name, "IBM 1.4.2",
making it difficult to distinguish between the two. It is therefore recommended
to use "alternatives" to switch between them reliably instead of
"system-switch-java":

alternatives --config java

alternatives --config javac

These new java-1.4.2-ibm-sap packages provide the Java 2 Runtime Environment
(JRE), which consists of the Java virtual machine, the Java platform core
classes and supporting files. It is the runtime section of the Java 2 SDK, but
without the development tools such as compilers and debuggers.

These new packages also provide the Java 2 Software Development Kit (SDK), which
is a development environment for building applications, applets, and components
that can be deployed on the Java platform. The Java 2 SDK software includes
tools useful for developing and testing programs written in the Java programming
language.

Users of SAP who require IBM Java 1.4.2 packages for SAP, and who have already
uninstalled any previous java-1.4.2-ibm packages for Red Hat Enterprise Linux
for SAP from their system, may install these new SAP-specific packages, which
provide the IBM Java 2 Runtime Environment (JRE) and IBM Java 2 Software
Development Kit (SDK)
