red5-web.properties getting reset when antmedia is restarted

[Daniel B]

I'm using enterprise edition in cluster mode. I need to make changes in all apps to set:

settings.maxResolutionAccept=1080
tokenHashSecret=hash
settings.hashControlPublishEnabled=true

Every time antmedia restarts all three settings get reset to:

settings.maxResolutionAccept=0
tokenHashSecret=
settings.hashControlPublishEnabled=false

There is only one app that keeps these changes. And on that app when it was first created I made these changes before restarting antmedia. That's the only difference I can see. How can I make these changes stick?

FYI the same thing happens if I change a setting for an app in the admin area so I don't change anything there.

And I see this in the logs when I restart:

2021-02-24 11:25:23,346 [vert.x-eventloop-thread-3] INFO  i.a.enterprise.cluster.TcpCluster - Update settings from cluster for app:APPNAME
2021-02-24 11:25:23,348 [vert.x-eventloop-thread-3] WARN  i.a.AntMediaApplicationAdapter - app settings updated for APPNAME

So where is it updating from?

Hi Daniel,

Thank you for the great question!

You just need to change these settings in MongoDB. But please also update "updateTime" parameter in MongoDB app settings. 

I hope, I could help you.

All the docs say to make these changes in red5-web.properties and restart. I don't know anything about MongoDB. Can you give me an example of how I could make these changes via mongo command line? 

Thank you for your help.

Hi Daniel,

Our documents refer to standalone mode by default. You can use Mongo DB GUI(Robo 3T) for your requirements.

Here are the steps:

1- Install Robo 3T.

2- Login MongoDB with your mongo db credentials

3- Double click clustertab/Collections/AppSettings tabs.

4- Select the setting which is you are using. 

5- Change settings what you want.

PS: After changes settings, please update "updateTime" parameter with the current timestamp.

I have attached some details about the GUI. I believe you can do it. 

Let me know if there is anything I can help you with.

Best Regards,

Selim

Thank you Selim that was very helpful. The last app I added (the one where red5-web.properties doesn't get reset) is not in the database under app settings. It seems to be working as it should. But should I somehow add it to the database? Or if it's not needed can I remove the others so they will use the red5-web.properties files? I don't know why the last app I added is not in there but liveapp and WebRTCAppEE are also missing.

Ok I understand how it works now. When you save settings in the admin panel it adds/updates the settings in the db for that app. The one app I had that wasn't in the DB wasn't in the DB because I never saved settings in the admin area for that app. I made all the changes I needed in red5-web.properties.

Hi Daniel,

Have a good day.

Absolutely right!

The one app I had that wasn't in the DB wasn't in the DB because I never saved settings in the admin area for that app

Just go Ant Media Server Dashboard Application settings and click save button. After that, please check MongoDB again.

I made all the changes I needed in red5-web.properties

If you add/change settings in Mongo DB settings, no need to change local red5-web.properties file. Server applications get the settings from Mongo DB.

I hope, it's clear.
