NAME
       jsadebugd - Serviceability Agent Debug Daemon

SYNOPSIS
       jsadebugd pid [ server-id ]
       jsadebugd executable core [ server-id ]


PARAMETERS
       pid
          process id of the process to which the debug server should attach.
          The process must be a Java process. To get a list of Java processes
          running on a machine, jps may be used. At most one instance of the
          debug server may be attached to a single process.

       executable

       Java executable from which the core dump was produced

       core
          Core file to which the debug server should attach.

       server-id
          Optional unique id, needed if multiple debug servers are started on
          the same machine. This ID must be used by remote clients to identify
          the particular debug server to attach. Within a single machine, this
          ID must be unique.

DESCRIPTION
       jsadebugd attaches to a Java process or core file and acts as a debug
       server. Remote clients such as jstack, jmap, and jinfo can attach to
       the server using Java Remote Method Invocation (RMI). Before starting
       jsadebugd, rmiregistry must be started with:

          rmiregistry -J-Xbootclasspath/p:$JAVA_HOME/lib/sajdi.jar


       where $JAVA_HOME is the JDK installation directory. If rmiregistry was
       not started, jsadebugd will start an rmiregistry in a standard (1099)
       port internally. Debug server may be stopped by sending SIGINT
       (pressing Ctrl-C) to it.

       NOTE - This utility is unsupported and may or may not be available in
       future versions of the JDK. jsadebugd is not currently available on
       Windows platforms.
