    78
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:
