ECP Collector and Analyzer

[Bob_271]

Hello Everyone,
I installed the HP Open VMS
ECP Collector/Analyzer on our Alpha VMS 7.2-2 software and I'm trying to open the DECwindows Motif with the command: >>plan analyze/motif

I get a message:

dsa0:[sys0.syscommon.][sysexe]ecp$analyze_motif.exe;1: Can't open display

The installation went ok, did I do something wrong or is the DECwindows Motif installed correctly? How can I tell?

Thanks for any help.

Hello Bob,

looks like your display is not setup correctly.

I do assume you are not sitting in front of a
workstation.

What does the command show display tell you?

To redirect to e.g. a PC use

set disp/crea/trans=tcpip/node=

(If you do have decnet trans=decnet works too ;-)

You do need to have an Xserver running on the remote system.

For more complete info check the help on set display.

Hi,

Further to Martin's reply, you can replace ip address with nodename. Also, if you are directing it to your PC , then make sure you start your x-server application first (for eg. if your are using excursion , then start it first before giving your command on VMS)
Anyway, it will be helpful if you paste the output of command $SHO DISP here.

HTH,
Thanks & regards,
Lokesh

This problem looks only to wrong setup of youre display. It doesn't matter PC or VXT. I'm using mij VXT2000+ (yes, already 11 years old) and works fine. Only I prefer LAT because its fast.
The command $ SHOW DISPLAY should give you the answer.
There must be a motif server running on VMS and thats it. With SET DISPLAY/NODE=/CREATE should do the trick.

Thanks for the replies. Here is the reply I get when I do a show display: (BTW: I am working from a PC using Dynacomm as the terminal emulator)

%DECW-W-OPENIN, error opening DECW$DISPLAY as input
-SYSTEM-W-NOSUCHDEV, no such device available

It looks like I have some additional steps to take?

Bob,

is your DECWINDOWS started?
$ SHOW SYSTEM/PROCES=DECW$*
should show DECW$FD.
If not, what is the value of
$ MC SYSGEN SHOW WINDOW_SYSTEM
The value for current should be 1.
If not, then set it (preferentially in MODPARAMS, followed be AUTOGEN) & reboot.

If DECW$FD is running, then forget this post.

Hello;
When I did the command:
show system/process=DECW$*

It didn't reply anything, just brought me back to the dcl prompt,(didnt find any DECW$ processes)

I did the MC SYSGEN SHOW WINDOW_SYSTEM
I got:

Current Default Min. Max. Unit Dynamic
1 0 0 255 Pure-numbe D

Hi,

This means you are not running dec windows.
If you want to disply analyzer window on you VMS station only, then DECW$* proccess is required. But, this is not necessary. I am using ECP and my VMS node do not run DEC windows. In this case what you need to do is load a x-server software on you windows PC ( for eg. I am using excursion ). Then start excursion on you pc. Log into your VMS node and give the following command:

$set display/creat/trans=tcpip/node=
$plan analy/motif

This will open analyzer window on you PC.

HTH,
Thanks & regards,
Lokesh

P.S. If your are not having excursion etc...then find a VMS node where you are running Decwindows. Or simply, start decwindows on your VMS .

[Bob_271]

I will load the excursion software. Is this shareware?
Thanks again.

Hi ,

you can find more information about excursion X server here:

http://h71000.www7.hp.com/pathworks32/

But, as I said earlier too, you can start DEC windows on your VMS and can see analyzer window there. Also, you can directly create CSV files, using /CSV_* qualifier. Read ECP user guide for more information.

Thanks Lokesh and everyone else!

Hi,

actually you do not need to have DECwindows started on your VMS system for this to work. You do need to have the software installed so the shareable libraries are available (that seems to be the case here, else you would get a different error message).

So all you do need is to install an X11 server on your PC (Linux is perfect, since it comes with X11 build in), do the set display on your VMS system and off you go.

Hello All,
Installed xServer without activating DecWindows on VMS and it is now working.
This forum is awesome. Thanks again.
