NonStop Server for Java 5.1 Programmer's Reference

Configuration Requirements
This subsection explains how to configure your system for the J2SE JDK by understanding the
following:
Creating Larger or Additional Swap Files●
Setting Environment Variables●
Symbolic Link●
Configuring TCP/IP and DNS for RMI●
Note: Do not install any JAR or native library files under the NonStop Server for Java
installation directory.
Creating Larger or Additional Swap Files
HP recommends a total swap files size of 512 MB (1024 Extents, 255 MaxExtents) for each
processor that runs the Java virtual machine (JVM). If you plan to run multiple large processes in the
same processor, you might need to create additional swap files because processes running in the same
processor share the same swap file.
Your system administrator can use the NSKCOM tool to create additional swap files.
To add swap files, you must log on to your NonStop operating system as a super-group user. Then,
from the Guardian TACL prompt, run the NSKCOM tool. From within the NSKCOM tool, use the help
add and help start commands to get more information. For further information, see the Kernel-Managed
Swap Facility (KMSF) Manual.
Setting Environment Variables
The following subsection describes the variables that define the environment in which Java operates.
PATH
The environment variable PATH enables Open System Services (OSS) to find the Java executable files.
As a convenience so that you do not have to fully qualify the Java executable, add the absolute path of
the java/bin directory to the PATH environment variable.
To add the absolute path, use this command:
export PATH=/install_dir/java/bin:$PATH
where install_dir is the directory in which the NonStop Server for Java 5.1 was installed. By
default, this is /usr/tandem.
