run this tool<o:p></o:p></span></b></p>
<p>You need to use the Java 2 Platform, Standard Edition version 1.4.1 or
higher Java Runtime Environment (JRE) to run this tool.<span style='mso-bidi-font-size:
20.0pt'><o:p></o:p></span></p>
<p>Usage <Java path>java –<span class=SpellE><span class=GramE>Xmx</span></span><span
class=GramE>[</span><span class=SpellE>heapsize</span>] –jar ha<<span
class=SpellE>HeapAnalyzer</span> version>.jar</p>
<p>For example, java –Xmx1000m –jar ha11.jar</p>
<p>If there’s <span class=SpellE>java.lang.OutOfMemoryError</span> while
you are processing <span class=SpellE>heapdumps</span>, please try increasing
the maximum heap size (-<span class=SpellE>Xmx</span>) value to give the JVM
more memory.</p>
<p>Maximum heap size should not be larger than the size of available physical
memory size for this tool due to performance issue.</p>
