jsadebugd \- Attaches to a Java process or core file and acts as a debug server\&. This command is experimental and unsupported\&.

.SH SYNOPSIS

\fBjsadebugd\fR \fIpid\fR [ \fIserver\-id\fR ]

.TP
|
|
\fIpid\fR
|
|
The process ID of the process to which the debug server attaches\&. The process must be a Java process\&. To get a list of Java processes running on a machine, use the jps(1) command\&. At most one instance of the debug server can be attached to a single process\&.
|
|
.TP
|
|
\fIexecutable\fR
|
|
The Java executable from which the core dump was produced\&.
|
|
.TP
|
|
\fIcore\fR
|
|
The core file to which the debug server should attach\&.
|
|
.TP
|
|
\fIserver-id\fR
|
|
An optional unique ID that is needed when multiple debug servers are started on the same machine\&. This ID must be used by remote clients to identify the particular debug server to which to attach\&. Within a single machine, this ID must be unique\&.
|
|
.SH DESCRIPTION
|
|
The \f3jsadebugd\fR command attaches to a Java process or core file and acts as a debug server\&. Remote clients such as \f3jstack\fR, \f3jmap\fR, and \f3jinfo\fR can attach to the server through Java Remote Method Invocation (RMI)\&. Before you start the \f3jsadebugd\fR command, start the RMI registry with the \f3rmiregistry\fR command as follows where \fI$JAVA_HOME\fR is the JDK installation directory:
|
|
.sp
|
|
.nf
|
|
\f3rmiregistry \-J\-Xbootclasspath/p:$JAVA_HOME/lib/sajdi\&.jar\fP
|
|
.fi
|
|
.nf
|
|
\f3\fP
|
|
.fi
|
|
.sp
|
|
If the RMI registry was not started, then the \f3jsadebugd\fR command starts an RMI registry in a standard (1099) port internally\&. The debug server can be stopped by sending a \f3SIGINT\fR to it\&. To send a SIGINT press \fICtrl+C\fR\&.
|
|
.PP
|
|
\fINote:\fR This utility is unsupported and may or may not be available in future releases of the JDK\&. In Windows Systems where \f3dbgeng\&.dll\fR is not present, Debugging Tools For Windows must be installed to have these tools working\&. The \f3PATH\fR environment variable should contain the location of jvm\&.dll used by the target process or the location from which the crash dump file was produced\&. For example, \f3s\fR\f3et PATH=%JDK_HOME%\ejre\ebin\eclient;%PATH%\fR\&.
