THD User Command
NAME
thd - Display JVM Thread Status
SYNOPSIS
thd [OPTIONS]
OPTIONS
-V
Verbose -- If the associated application is compiled to include DEBUG
information the classes where a line number may be available are
displayed from the thread's stack trace. This provides information as
to what part of the program is being executed.
-E
Shows changes in process time. When the THD command is executed without
the -E option the process times are recorded for use here. The -E option
then uses those saved times to display the elapsed process time. This
can be used to check thread activity.
-X
Extended -- This provides detailed stack trace information.
DESCRIPTION
Applications are written in Java and each executes with its own instance of
a Java Virtual Machine (JVM). The THD command displays the status of each
active JVM.
Each process is listed along with the accumulated process time, memory
usage, PID and stack as would be displayed by the PS command. In addition
the amount of memory associated with active Java Objects and classes is
shown.
Each Thread in the program is enumerated along with the associated
amount of runtime accumulated by the thread. The status of the thread is
indicated. For instance SLEEP is shown if a thread has executed a
sleep().
If an application sets a system Watchdog the status of the watchdog is
displayed along with the remaining time on its timer.
