5 Verify that the action taken by TotalView for the SIGTERM signal is appropriate.
(You can examine the current action by using the Process Window
File > Signals command. See “Handling Signals” on page 69 for more information.)
PVM uses the SIGTERM signal to terminate processes. Because TotalView
stops a process when the process receives a SIGTERM, the process is not
terminated. If you want the PVM process to terminate, set the action for
the SIGTERM signal to Resend.
TotalView will automatically acquire your application’s PVM processes. For
more information, see “Automatically Acquiring PVM/DPVM Processes” on
page 154.
Starting a DPVM Session
Starting a DPVM debugging session is similar to starting any other
TotalView debugging session. The only additional requirement is that you
must start the DPVM daemon before you start TotalView. See the DPVM
documentation for information about the DPVM daemon and its console
program. The procedure for starting an DPVM application is as follows
1 Use the dpvm command to start a DPVM console session; starting the
session also starts the DPVM daemon.
If DPVM isn’t running when you start TotalView (with DPVM support
enabled), TotalView displays the following error message before it exits:
Fatal error: Error enrolling as DPVM task: dpvm error
2 Enable DPVM support either by using the TV::dpvm CLI variable or by
using the –dpvm command-line option to the totalview command.
The command-line options override the TV:dpvm command variable. For
more information on the totalview command, see “TotalView Command Syntax”
in the TotalView Reference Guide.
3 Verify that the default action taken by TotalView for the SIGTERM signal is
appropriate. (You can examine the default actions with the Process
Window File > Signals command in TotalView. See “Handling Signals” on
page 69 for more information.)
DPVM uses the SIGTERM signal to terminate processes. Because
TotalView stops a process when the process receives a SIGTERM, the process
is not terminated. If you want the DPVM process to terminate, set
the action for the SIGTERM signal to Resend.
If you enable PVM support using the TV::pvm variable and you need to use
DPVM, you must use both –no_pvm and –dpvm command-line options
when you start TotalView. Similarly, when enabling DPVM support us the
TV::dpvm variable, you must use the –no_dpvm and –pvm command-line
options.
