IBM Pattern Modeling and Analysis Tool for Java Garbage Collector

Operating system: Java™ 2 Platform, Standard Edition

Hardware: Memory larger than the verbose GC trace size

Software:

• Java Run-time Environment 1.4.2 or above
• Log files with verbose:gc or Xverbosegc enabled on IBM® JVM 1.3.x,1.4.x, 5.0, and 6.0; Solaris JVM 1.4.1/1.4.2/5.0/6.0; or HP-UX JVM 1.4.1/1.4.2/5.0/6.0.

1. Unzip gaNNN.zip (NNN is the version number).
2. Unzip readmeNNN.zip and read the readme file.
3. Run gaNNN.jar with the Java Run-time Environment.

The following is an example of processing a verbose GC trace with PMAT Version 1.0.1 and about 500 MB of Java heap size:

<Java Runtime Environment path>java -Xmx500m -jar ga101.jar
