Is there a special upgrade process for Java/MANGO that I have to pay attention once this is in a production environment or is that straight forward?

Thanks in advance,
José

The problem to upload it seems

Yes Phil I do have hs_err files.
I upload the last ones hope it may help [1_1515084790078_hs_err_pid592.log](Uploading 100%) [0_1515084790077_hs_err_pid568.log](Uploading 100%)

Hello

Now and then production Mango solution is found "crashed"! With this I mean that MANGO Stops once we can get access to Webmin.

Looking to the generated logs I found a common message about Java than says: "Failed to write core dump. Core dumps have been disabled. To enable core dumping, try ulimit -c unlimited before starting Java again"

My question is: Is it or not recommended to issue the specified command?

ulimit -c unlimited

If you does not recommend it what should I try to solve the MANGO crashing issues?

Thanks in advance,
José

Hi Phil,

I send you a message to support.

Thank you,
Jose

I will come back to the simultaneous alarm issue after I collect some more info.

meanwhile, after upgrade to MANGO v 3...

A) In Home I can not see the number of datasources, datapoints, etc. in the up right corner of the square. Also, Active Sessions, Event Detectors and Mailing Lists are not clickable.

B) !!systemSettings.lastUpgrade!! in Administration > System settings > System information, with 1500555481 as date.

and this one, last two from ma.log?

WARN  2017-07-24T14:50:10,495 (com.serotonin.m2m2.util.timeout.TaskRejectionHandler.rejectedTask:77) - Rejected task: User event cache cleaner because Task Queue Full

thank you very much,
Jose

Now within MANGO v3 UI, once in awhile I see the following messages in the bottom screen:

connectivity lost... ok
(after 2 sec)
connectivity to MANGO API as been restored

My mangoApi module is 3.1.1

Once mangoNoSqlDatabase is depending on it, could this be in any way related to the problem that we have? (please see bellow reminder text). Is there any log where I can see more info? I search in the ma-log and found nothing.

(reminder)
let me remind you: when more than two simultaneous BACnet devices have it value switched only aleatory two reach's the http publisher. This is the only issue that holding us down to close the project... :-(

Thank you,
Jose

please answer to the issue about the license that I sent you to support.
Thank you

After the upgrade I get

???systemSettings.noSqlDatabaseSize(i18n_pt_PT)???

in the System settings > System Information section when refreshing the database size.

Should I worry about or is only a none translated item?

It works!!!
What could be wrong?

Thank you very much. I can sleep better this night :)

@phildunlap

you have right with the issue 127.0.1.1 mangoes. I fix it but then I get

root@mangoES3249:/opt/mango/bin$./ma.sh start
MA_HOME is /opt/mango
./ma.sh: line 31: /opt/mango/bin/ma-start.sh: Permission denied

to all I get the same result:

sudo: unable to resolve host mangoES3249

unless for

sudo su; ./ma.sh start

where I get the PuTTY screen again - with the calendar, cpu info, etc. - as when I entered

here is the result

mango@mangoES3249:/opt/mango/bin$sudo ./ma.sh start
sudo: unable to resolve host mangoES3249
[sudo] password for mango:
sudo: ./ma.sh: command not found

Hi Phil,

It does not work... :(

So I have cross my fingers and do a version upgrade to MANGO 3...

Now MANGO's not responding! (snif!). "ERR_CONNECTION_REFUSED" is all I get as browser response. The Webmin is working fine. Is there something else I can try before I restore the Mango directory ?

Thank you

Hi Phil,

I'm not figure it out... the code

TIMESTAMP = source.time+1; //one millisecond later than the source's TS
//you could use +2 on another one, and so on

Adds only a timestamp or in fact inserts a delay? Or both?

Thank you

@phildunlap said in How to change the http sending value parameter:

Whoops. Looks like there was a missing parenthesis. Fixed.

As the syntax error persists I try one more missed parenthesis. Your answer and Notepad++ made me see that conclusion. So 2 added.

outputFile.write( json.dumps( {"pointLinks": config["pointLinks"]}, indent=4, sort_keys=False, separators=(",",": ") ) )

Thank you

@phildunlap said in How to change the http sending value parameter:

Wow 1800! Are they all to the same target point? At a certain number we may want to rethink the general tactic of wedging lots of points' alarms out one point. But, if it works, ok.

Off hand I can't think of a way to do what I was describing in the global script, but here's a python script to mass modify your point links. You probably want to keep a JSON backup of them, in case you wish to revert.

import json

configFile = open("/path/to/Mango/backup/Mango-Configuration.json")
config = json.load( configFile )
configFile.close()

x = 0
for pl in config["pointLinks"] :
  if pl["script"] != "" :
    pl["script"] = "TIMESTAMP=source.time+" + str(x) + ";\\n" + pl["script"]
    x += 1

outputFile = open("/path/to/output.json", "w+")
outputFile.write( json.dumps( {"pointLinks": config["pointLinks"]}, indent=4, sort_keys=False, separators=(",",": ")
outputFile.close()

Sorry. I get an invalid syntax at outputFile.close()

I'm hopping to test the first code in six or 8 link points. That I can do one by one... ;-)

Thanks in advance for the second code.

I'll feedback to you.

Cheers

Hi Phil,

Where do I put it? Sorry but I can figure it out. Probably because I have 1800 point links... I'm lost here. :-(

As instructed previously by you I put a Global script

function getPrefix() { /*So that you may change the prefix for all scripts later if required */
    return "4";
}

this is running on all point links. Is any way to add the time code here? Or am I confused? (its not the first time :D )

thank you

Hi
I follow the instructions here:
https://forum.infiniteautomation.com/topic/2055/changing-datasource-of-datapoint/3
that work like a charm.
The problem is after this I can no more access the menu Data Point Details.
Any suggestions?
