Locked Re: Java heap error

 

David K,

My memory recalls some issues where there were a lot of roster entries and
many with large pictures. The effect was a Java memory error because it was
trying to process every roster entry, and photo attached. That took all the
memory and some.

The way the photos are used only needs about 100k for resolution. On
throttles you never see a real big picture so it doesn't matter. In this
case a club had cataloged everything with a new phone and that was around
3Meg per picture, quite a few hundred roster entries as I recall. The
original roster was around 5-10Gig and that crashed things. After downsizing
the pictures, all was well. You would have to go into the roster, via
Help->Locations, and use the detailed view in the file browser to see what
size things were.

Not sure if this fits but was something that triggered bad in the Java side
of JMRI.

Looking for advice on what to do on a PC that is used only for programming locos. I only upgrade it to the production versions so last month I went from the version last Dec 2018 to 4.16. The machine is not ?on the internet.?

All seemed well until today when we got the fatal java error. The machine has java 1_8_0_221. Windows 7.?

Suggestions? ?Decoder Pro opens and can pull up the roster and then the error occurs. I don¡¯t think the steps matter, I think it is after a minute or so the error. I shut down and restarted the PC and still get the error.?

When I do a Factory reset...AND then run the locomotive with address..3....all works as expected except for a noise that sounds like an engine fan of some sort. When I "SHIFT-F-8" all sounds stop as they should EXCEPT this simulated engine fan. I suspect the previous owner edited a CV that is not influenced with the ATLAS factory reset system since it was not part of the Atlas programming.
All CVs are reset by an ESU (JMRI Program Track->Resets menu).


Is there a way to find out what CV (or combination of CV's) is running that simulated fan noise so I can stop it? Can I use DecoderPro to find that CV?
Once you've Reset, Read All CVs as per my earlier instructions, saved and closed the roster entry, you can:

- Reopen the saved Roster Entry using Program on Main.
- Put loco on Main and activate sound.
- Go to Sound Levels pane.
- Move the slider for Random Sounds to zero. Write Changes on Sheet. See if sound stops.
- Move the slider for Sound Slot 1 to zero. Write Changes on Sheet. See if sound stops.
- Move the slider for Sound Slot 2 to zero. Write Changes on Sheet. See if sound stops.
- Move the slider for Sound Slot 3 to zero. Write Changes on Sheet. See if sound stops.
- Repeat as needed until you find the offending sound slot.

Once found, get back to us with the information for further instructions.

using IP already, and port number is correct.

hmm... kinda looks like i will have to manipulate MQTT some other way. I have a Raspberry Pi 4 that i was thinking of using as the "train" desktop. should be a good way to bypass whatever is on this computer blocking the connection. ;)

In any event, thanks?Dave, for your help!

Obviously it is trying to make the connection at startup. You get that error if the hostname is unreachable or the port number is incorrect (verified by changing the hostname of my broker to something fictitious). Try using the ip address. If that works, then dig deeper to find why the name resolution is not finding it. Check the correct port number. Some Windows firewall products block outgoing connections based on the application being used so it could still be that.

Then set CV29 to use the short address in each, program each one as required

for operations where they would both respond to the long address.

Since the Soundbug uses different CVs (except for address and CV 29) than the mobile decoder it's connected to, there is no real need to do this.

Locked Re: restoring sensors and blocks

 

Thomas,

Reading is what I would try first. Then writing something simple. If they
are not responding, I'll guess they might only need a reset and then restore
the addresses. Then dump the saved roster file to the board. You did save
the roster entry when you programmed the board originally?

GPON referrers to the 'global power on' and it is a set of messages asking
all turnouts and sensors to report their current state during the power on
of the command station.

Locked Re: Multi decoders in a loco. How do I program them in DP?

 

Pete,

That is a method many use for decoders. The biggest trick is knowing the
values for the short address. I use single digits and either paint a number,
make scratches, or something on the bottom/hidden, to remind me. Then that
single command to change CV29 back and forth does the trick.

Now the theory of the soundbug is that there aren't conflicts, both decoder
get the same values when they use the same value, but you would get read
conflicts since neither responses at the same moment. Most of the values do
not exist in each decoder, only one or the other. I keep them separate as I
don't trust both doing something at the same time.

There is no way for JMRI to see the Soundbug as it doesn't provide any acknowledge

Manually select the appropriate SFX Sound Only Decoder from the digitrax list and create a roster entry and program from there.
I suggest you read the manual for it and maybe check the Digitrax website for any specifics regarding programming this decoder.

Ken,

I did try to program on the main with one of the boards. Nothing seemed to happen. The value boxes remained red after trying to write them. There are ¡°read¡± and ¡°compare¡± buttons as well. Are they what you are referring to on the configuration of the boards in JMRI Decoder Pro in the roster entry for those boards. Im not sure what GPON stands for. It seems that I had more luck programming these boards on the the programming track when instilling them instead of on the layout in programming on the main, so I think I will pull it from the layout and take it to the programming track.

Thomas,

Have you tried to talk to the TD boards? I presume you have roster entries
from programming them? So do they respond? On the main page of the config
for each board is an option that sets if the board should respond to the
GPON. If those are set, you should see all of the sensors and turnouts after
the startup. Since it is a standalone LocoNet, you may need to manually
trigger that. It's been a long time and I don't recall the right trick right
now.

But if you can't talk to the boards with ops mode programming, that's a clue
they could be dead.

You had best go to the Digitrax group, if there is one, ask Digitrax or read the
instructions for the Sound Bug and if you don't have them, download them from
the Digitrax site.

Just a guess and from a weak memory, you give each decoder a unique address,
program them the way you want, then give both decoders the same address.

When did it last work for you?
What MQTT devices have you set up?
What channel name do you have? If you have the wild card on the end of the channel name, remove it, it no longer applies.

Jason,

- Copy ShutDownExample.py to your user files location. ?See Help >> Locations for the actual path.
- Edit your private copy with a text editor. ?Avoid NotePad if using Windows. ?I use WordPad.
- Add a line after the "def execute(self):" line:

- Replace turnout name with the user or system name for the turnout that controls the funicular. ?Keep the quotes around the name.
- Make sure that the added line has the same number of leading spaces as the following lines.
- Go to Preferences >> Start Up
- Select Add >> Run script¡­

- Save your preferences change and restart.

The script will start when you start JMRI. ?It will then wait until JMRI is stopped, at which time it will send the turnout command.
