Introduction There are many tools available for use with Java on HP-UX 11i. Some of these tools are unique to HP, and some of the tools are also found on other platforms. This paper provides information about the tools, to help in understanding which tools to use when migrating to the HP-UX 11i platform. This white paper provides an overview of tools that are designed for use with Java and is divided into four major parts: Quick Start – provides an overview of where to find the tools for Java.

• • • Options that behave the same on both platforms o -interval=n : set update interval to n seconds o -notile : do not initially tile windows o -pluginpath : specify list of directories or jar files searched for plug-ins o -version : print version and exit o -help : display help message o -J
PAGE 5
o • : use Servicability Agent to access remote Java processes First available with 6.0.03 on HP-UX 11i jmap The jmap tool creates a Java memory map (heap dump) for a running JVM or extracts the information from a core file.
PAGE 6
o • -f : read and evaluate script from standard input o help, -? : display help message o -q : list all available script engines Options that behave differently o none jsadebugd The Java Servicability Debug Daemon acts as a debug server for a running JVM or a core file. • This tool is not available on HP-UX 11i jstack The jstack tool produces stack traces for Java processes or core files.
PAGE 7
o none jstatd jstatd is an RMI server application that acts as an interface for remote monitoring tools.

HP-UX 11i Java Tools Overview HP provides several tools that are designed to enhance Java performance on HP-UX 11i systems. HPjmeter The HPjmeter tool is used for performance analysis of Java applications. HPjmeter has two main modes of operation – displaying real-time data from a running JVM or analyzing various types of static data files generated by the JVM.
PAGE 9
GlancePlus GlancePlus is an advanced performance monitoring tool for HP-UX 11i systems, which is available with a GUI or a text-based interface. Both versions can provide the same set of information – systemwide performance data and process-specific data. If you have GlancePlus installed on your HP-UX system, you can use the GlancePlus Adviser script, javaGlanceAdviser.ksh, from the Java Migration Kit to collect information about a Java process. (This script is also included in the HPjmeter 4.
