Final product information

This section contains final product information for the IBM(R) Developer Kit for Linux(R), Java(TM) 2 Technology Edition, Version 1.3.0. Read the following subsections for information regarding changes to the Developer Kit.


Runtime Environment for Linux supported on Red Hat 7.1

The Runtime Environment for Linux(R), Java(TM) 2 Technology Edition, Version 1.3.0 is supported on Red Hat(R) Linux 7.1.


Setting the Red Hat 7.1 floating stacks environment variable

When the 2.4 kernel is used, Red Hat also uses a new feature in glibc called floating stacks. The JDK shipped in the Red Hat 7.1 distribution is not compatible with the floating stacks feature. To work around this incompatibility, you can force the loader to use a version of glibc without the floating stacks feature. This is done by setting an environment variable to tell the loader to act as if the 2.2 (instead of the 2.4) kernel is being used.

If the JVM is invoked by one of the standard IBM wrapper scripts (such as java or javac), this environment variable will be set automatically. If the java executable is invoked directly, or the JVM is embedded in an application and called by JNI_CreateJavaVM(), then the environment variable must be set before the application is invoked.

To set this evironment variable, type the following at the command prompt:

export LD_ASSUME_KERNEL=2.2.5
NOTE: The environment variable does not cause the 2.2.5 kernel to be used; it only affects which glibc is used.


Runtime Environment for Linux supported on SuSE 7.1

Runtime Environment for Linux, Java 2 Technology Edition, Version 1.3.0 is supported on SuSE Linux 7.1.
