jstack - Stack Trace
SYNOPSIS
jstack [ option ] pid
jstack [ option ] executable core
jstack [ option ] [server-id@]remote-hostname-or-IP
PARAMETERS
Options are mutually exclusive. Option, if used, should follow
immediately after the command name.
See OPTIONS.
- pid
- process id for which the stack trace is to be printed.
The process must be a Java process. To get a list of Java processes
running on a machine,
jps
may be used.
- executable
- Java executable from which the core dump was produced.
- core
- core file for which the stack trace is to be printed.
remote-hostname-or-IP
- remote debug server's (see
jsadebugd) hostname or IP address.
- server-id
- optional unique id, if multiple debug
servers are running on the same remote host.
DESCRIPTION
jstack
prints Java stack traces of Java threads for a given Java
process or core file or a remote debug server. For each Java frame,
the full class name, method name, 'bci' (byte code index) and line
number, if available, are printed. With the -m option, jstack prints
both Java and native frames of all threads along with the 'pc'
(program counter). For each native frame, the closest native symbol
to 'pc', if available, is printed. C++ mangled names are not
demangled. To demangle C++ names, the output of this command may be
piped to c++filt.
NOTE - This utility is unsupported and may or may not be available in
future versions of the J2SE SDK.
jstack is not currently available on Windows platforms or on
the Linux Itanium platform.
OPTIONS
- -m
-
prints mixed mode (both Java and native C/C++ frames) stack trace.
- -h
- prints a help message.
- -help
- prints a help message
SEE ALSO
KNOWN BUGS
Mixed mode stack trace, the -m option, does not work with the
remote debug server.
