Wanted to check in and see if this issue was able to be re-created, and if there are any updates.

Thanks,

Thanks, Terry, we will try that.

Yes, they are all enabled. If we just save one that is considered undefined, then it will "fix" that one, but it pushes another one out of the list. Almost like it just recognized the 100 "newest" or most recently saved.

Thanks,
Chad

Hi, All,

Hopefully this is something others have come across and there is an easy fix.

We have a scripting data source which has more than 100 data points. In our script, we try to set the value of all the 100+ data points. The problem is that the script says that all of the data points past the 100 mark are undefined.

IE: if we say varDataPoint101.set(true) or varDataPoint101.value then the script validator says varDataPoint101 is undefined.

Is there a way for the script to pull in and recognize more than 100 data points that are associated with it? We're also using the CONTEXT_POINTS object which seems capped at 100 as well. I'm guessing a fix for one will be a fix for both.

Thanks,
Chad

Thanks, Joel.

I was still getting an error, but found this command on Stack Overflow for a post around port permissions and it did the trick for me.

sudo /sbin/sysctl -w net.ipv4.ip_unprivileged_port_start=0

Thanks,
Chad

Joel,

The URL specified for the install script returns a 404 error.

Is there an updated one to use?

Thanks,
Chad

Thanks, Joel, I'll try that here shortly and let you know!

We have port 80 specified in our properties file; web.port

Thanks,
Chad

We have been running Mango on Windows for a couple years now and want to get a Linux server up and going.

We have an Amazon Linux server with all the necessary software installed, and can start the instance using:

sudo ./ma-sh start

The problem is when we try to start the app using the mango user we get the following:

[ec2-user@ip-xxx-xxx-xxx-xxx bin]$ sudo -u mango ./ma.sh start
MA_HOME is /opt/mango
[ec2-user@ip-xxx-xxx-xxx-xxx bin]$ ma-start: MA started with Process ID:  21478
ma-start: no restart flag found, not restarting MA
ma-start: MA done

Some times we get more info on the error and it says:

ERROR 2021-06-02T01:59:07,431 [main] - Error during initialization
java.net.SocketException: Permission denied

This seems like a permissions issue, but we're not sure where. /opt/openjdk has been changed to be owned by mango:mango as well as the /opt/mango directory structure.

I've followed the steps in the Linux Install page: https://docs-v3.mango-os.com/linux-installation

I've also followed the advice in this post https://forum.mango-os.com/topic/3278/java-update-to-1-8-162-has-caused-mango-es-3-2-2-to-become-unreachable/13 but that didn't seem to do anything either.

Any help is appreciated.

Thanks,
Chad

Thanks once again, Fox, for the help!

It took us a little bit to figure out the syntax, but got it working: /rest/v2/data-sources?limit(1000)

We tried to use -1, but that created a 500 error.

Could not write JSON: PreparedStatementCallback; bad SQL grammar [select `ds`.`id`, `ds`.`xid`, `ds`.`name`, `ds`.`dataSourceType`, `ds`.`data`, `ds`.`editPermission` from dataSources AS ds limit ?]

Not a big deal for our purposes though.

When running the /data-sources GET via the API the total reports the actual number of data sources we have, but the items array is limited to 100 data sources.

Is there a "limit" parameter or paging option that I'm missing?

How can I get all of the data sources returned to me via the API?

Thanks,
Chad

We installed Adopt OpenJDK v11.0.10.9 on our production environment last Thursday and for a couple days things looked good; CPU was steadily at or below 4%. On Saturday it jumped up to 16% and is holding there, which is the same behavior we saw with v14 of Adopt OpenJDK. Every few days or weeks the CPU jumps and stays there until it gets to 99% and we have to restart the app to get CPU back down.
