Hi, Fox,

We didn't think to try the serial data source with a virtual socket. I may experiment with that to see what we can get going.

Thanks for the tip.

Chad

Great, thank you. Changing the name to include the _en and putting it into the overrides/classes directory worked perfectly.

@terrypacker Hi Terry, yup that's exactly what we've done in the meantime. Thanks for your help.

I'm running into trouble when new data gets imported though. See https://forum.infiniteautomation.com/topic/4867/meta-point-classcastexception

Hi Nurr,

all my windows installations work with this configuration:

https://forum.infiniteautomation.com/topic/4632/windows-10-services-for-mango

I've made some amendments (copy from above) - sure enough the data we needed was inside the runtime property. BUT I found the solution!
The sodding datapoint query doesn't work in 3.7 without setting the script permissions.
Normally these were populated by default, but this is no longer the case. In this case, make the script permission run as superuser to get your points through, or at least the user allowed to read those points.

Once you've done that you'll be away!

Fox

@shawn-hateley did you ever figure out a way to do this? thanks.

Hi Chad

Your assumptions are correct however mango will wait until it has 3 values. in other words when your data source initialises it will wait for 9 seconds until it gets the first 3 values.

Nope, this would likely be for version 3 and above. You could try upgrading your version 2 to a higher version 2 but I'm not sure how well it will work. If https is a must, I'd advise configuring a proxy for mango using apache or nginx.

Fox

@mattfox Thank you very much.

@robmalone Mango did not even what to start up with JDK 1.14. I did recover the old jdk I was using on the crashed system and will revert to that.

thx

FYI, I did upgrade the MySQL DB to 8.x over a week ago and all is running well; no issues.

Correct, you were using the wrong api url.

Thanks @MattFox !

Your datasources/scripts/users etc are all stored in the H2 database (or mysql if you're using that).
The physical file location depends on where your mango install is.
it will be [Mango DIR]\databases
The database itself is the mah2.h2.db file.
If you're after files you've uploaded, they will be in [Mango DIR]\filestore

Hope that is what you're looking for

Fox

@terrypacker Sorry for dredging up an old thread but I ran the same DELETE FROM EVENTS; as before but this time mango has failed to restart. It gets an out of bounds error when connecting to H2.

(com.serotonin.m2m2.Lifecycle.terminate:578) - Mango Lifecycle terminated.

Running the web console manually gives the same out of bounds error when the connection is tested.

General error: "java.lang.ArrayIndexOutOfBoundsException: 0" [50000-199] HY000/50000 Update

Managed to get it fixed (after a database restore) by:

SET REFERENTIAL_INTEGRITY FALSE; TRUNCATE TABLE EVENTS; SET REFERENTIAL_INTEGRITY TRUE; TRUNCATE TABLE USEREVENTS; Restart Mango

Database went from 6Gb to 17Mb.

Dear @CraigWeb, is there any update about topic?

Looks like I actually have to kill the safari session/close the tab window in order to make it work.
