jhat

jhat(1) 						      General Commands Manual							   jhat(1)

NAME

       jhat - Java Heap Analysis Tool

SYNOPSIS

       jhat [ options ] <heap-dump-file>

PARAMETERS

       options
	  Options, if used, should follow immediately after the command name.

       heap-dump-file
	  Java	binary	heap dump file to be browsed. For a dump file that contains multiple heap dumps, you may specify which dump in the file by
	  appending "#<number> to the file name, i.e. "foo.hprof#3".

DESCRIPTION

       The jhat command parses a java heap dump file and launches a webserver. jhat enables you to browse heap	dumps  using  your  favorite  web-
       browser.  jhat supports pre-designed queries (such as 'show all instances of a known class "Foo"') as well as OQL (Object Query Language) -
       a SQL-like query language to query heap dumps. Help on OQL is available from the OQL help page shown by jhat. With the  default	port,  OQL
       help is available at http://localhost:7000/oqlhelp/

       There are several ways to generate a java heap dump:

	  * Use jmap -dump option to obtain a heap dump at runtime;

	  * Use jconsole option to obtain a heap dump via HotSpotDiagnosticMXBean @
	    http://java.sun.com/javase/6/docs/jre/api/management/extension/com/sun/management/HotSpotDiagnosticsMXBean.html at runtime;

	  * Heap dump will be generated when OutOfMemoryError is thrown by specifying -XX:+HeapDumpOnOutOfMemoryError VM option;

	  * Use hprof @
	    http://java.sun.com/developer/technicalArticles/Programming/HPROF.html.

       NOTE: This tool is experimental and may not be available in future versions of the JDK.

OPTIONS

       -stack false/true
	  Turn off tracking object allocation call stack. Note that if allocation site information is not available in the heap dump, you have to
	  set this flag to false. Default is true.

       -refs false/true
	  Turn off tracking of references to objects. Default is true. By default, back pointers (objects pointing to a given object a.k.a refer-
	  rers or in-coming references) are calculated for all objects in the heap.

       -port port-number
	  Set the port for the jhat's HTTP server. Default is 7000.

       -exclude exclude-file
	  Specify a file that lists data members that should be excluded from the "reachable objects" query. For example, if the file lists
	  java.lang.String.value, then, whenever list of objects reachable from a specific object "o" are calculated, reference paths involving
	  java.lang.String.value field will not considered.

       -baseline baseline-dump-file
	  Specify a baseline heap dump. Objects in both heap dumps with the same object ID will be marked as not being "new". Other objects will
	  be marked as "new". This is useful while comparing two different heap dumps.

       -debug int
	  Set debug level for this tool. 0 means no debug output. Set higher values for more verbose modes.

       -version
	  Report version number and exit.

       -h
	  Output help message and exit.

       -help
	  Output help message and exit.

       -J<flag>
	  Pass <flag> to the Java virtual machine on which jhat is run. For example, -J-Xmx512m to use a maximum heap size of 512MB.
