jsadebugd - Unix, Linux Command
jsadebugd - serviceability agent debug daemon
jsadebugd pid [ server-id ]
jsadebugd executablecore [ server-id ]
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:
where $JAVA_HOME is the J2SE SDK 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 J2SE SDK.
jinfo is not
currently available on Windows platforms or
on the Linux Itanium platform.
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.
Java executable from which the core dump was produced.
core file to which the debug server should attach.
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.
