NonStop Server for Java (NSJ) Programmer's Guide (NSJ 2.0+)

To run the NSKCOM tool, you must log on to your NonStop

Kernel 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

You must set the environment variable PATH, but setting the environment variable

JAVA_HOME is no longer required.

You need to set the environment variable CLASSPATH only if you move any of the provided

.zip or .jar files or want to load a nondefault library (such as one that you develop).

PATH

The environment variable PATH enables Open System Services (OSS) to find the Java

executable files in the /usr/tandem/java/bin directory; therefore, you must add the

absolute path of the /usr/tandem/java/bin directory to the PATH environment variable.

To add the absolute path, use this command:

export PATH=/usr/tandem/java/bin:$PATH

Then (assuming that your startup file has the name ~/.startup_file_name), use the

following command to load it:

. .startup_file_name

For example, if your startup file had the name ~/.profile, you would use the following

command to load it:

. .profile

CLASSPATH

If you follow the default installation procedure, you do not need to set the environment variable

CLASSPATH. You must set CLASSPATH only if you move any of the provided .zip or .jar

files or want to load a nondefault library (such as one that you develop).

CLASSPATH tells the JVM and other Java programs in the /usr/tandem/java/bin

directory where to find the class libraries (for example, the rt.jar file in the jre/lib

directory). By default, the Java tools append the following file to whatever CLASSPATH you

have explicitly set:

libpath/tandemvm.jar:libpath/rt.jar

where libpath is /usr/tandem/java/jre/lib.
