jvisualvm - Java Virtual Machine Monitoring, Troubleshooting, and Profiling Tool SYNOPSIS
jvisualvm [ options ] PARAMETERS
Options, if used, should follow immediately after the command name. Options may be in any order. For a discussion of parameters that apply to a specific option, see OPTIONS below. DESCRIPTION
Java VisualVM is an intuitive graphical user interface that provides detailed information about Java technology-based applications (Java applications) while they are running on a given Java Virtual Machine (JVM(*)). The name Java VisualVM comes from the fact that Java Visu- alVM provides information about the JVM software visually. Java VisualVM combines several monitoring, troubleshooting, and profiling utilities into a single tool. For example, most of the function- ality offered by the standalone tools jmap, jinfo, jstat and jstack have been integrated into Java VisualVM. Other functionalities, such as some of those offered by the JConsole tool, can be added as optional plug-ins. OPTIONS
The following option is possible when you launch Java VisualVM. -J<jvm_option> Pass this <jvm_option> to the JVM software. USAGE
Java VisualVM is useful to Java application developers to troubleshoot applications and to monitor and improve the applications' perfor- mance. Java VisualVM can allow developers to generate and analyse heap dumps, track down memory leaks, perform and monitor garbage collec- tion, and perform lightweight memory and CPU profiling. Plug-ins also exist that expand the functionality of Java VisualVM. For example, most of the functionality of the JConsole tool is available via the MBeans Tab and JConsole Plug-in Wrapper plug-ins. You can choose from a catalog of standard Java VisualVM plug-ins by selecting 'Tools' | 'Plugins' in the Java VisualVM menus. Start Java VisualVM with the following command: % jvisualvm <options> SEE ALSO

libglpk-java - GNU Linear Programming Kit Java Binding DESCRIPTION
The GNU Linear Programming Kit (GLPK) package supplies a solver for large scale linear programming (LP) and mixed integer programming (MIP). The GLPK project is hosted at http://www.gnu.org/software/glpk. It has two mailing lists: - help-glpk@gnu.org and - bug-glpk@gnu.org. To subscribe to one of these lists, please, send an empty mail with a Subject: header line of just "subscribe" to the list. GLPK provides a library written in C and a standalone solver. The source code provided at ftp://gnu.ftp.org/gnu/glpk/ contains the docu- mentation of the library in file doc/glpk.pdf. The Java platform provides the Java Native Interface (JNI) to integrate non-Java language libraries into Java applications. Project GLPK for Java delivers a Java Binding for GLPK. It is hosted at http://glpk-java.sourceforge.net/. To report problems and suggestions concerning GLPK for Java, please, send an email to the author at xypron.glpk@gmx.de. ARCHITECTURE
A GLPK for Java application will consist of the following - the GLPK library - the GLPK for Java JNI library - the GLPK for Java class library - the application code. GLPK LIBRARY
The GLPK library can be compiled from source code. Follow the instructions in file INSTALL provided in the source distribution. Precompiled packages are available in many Linux distributions. The usual installation path for the library is /usr/local/lib/libglpk.so. The library has to be in the search path for binaries. GLPK FOR JAVA JNI LIBRARY
The GLPK for Java JNI library can be compiled from source code. Follow the instructions in file INSTALL provided in the source distribu- tion. The usual installation path for the library is /usr/local/lib/jni/libglpk-java.so. The library has to be in the search path for binaries. Specify the library path upon invocation of the application, e.g. java -Djava.library.path=/usr/local/libjni GLPK FOR JAVA CLASS LIBRARY
The source code to compile the GLPK for Java class library is provided at http://glpk-java.sourceforge.net. The GLPK for Java class library can be compiled from source code. Follow the instructions in file INSTALL provided in the source distribu- tion. The usual installation path for the library is /usr/local/share/java/glpk-java.jar. The library has to be in the CLASSPATH. Specify the classpath upon invocation of the application, e.g. java -classpath /usr/local/share/java/glpk-java.jar;. SEE ALSO
Further documentation and examples can be found in the documentation path, which defaults to /usr/local/share/doc/libglpk-java. version 1.0.18 September 10th, 2011 libglpk-java(3)
