Unable to purge events

[mseverin]

Thanks for all the suggestions.

I have started Mango in SAFE mode (verified by looking in the ma.log file but I still can't get logged in.

I changed the env.properties file to set set db.web.start=true and tried to run the H2 web Console using web-console.sh -webAllowOthers but I get the message "Web Console server running at http://127.0.1.1:8081 (only local connections).

I thought the flag -webAllowOthers would let me connect to the Console from my laptop.

Is there something I'm missing in order to run the H2 database manager?

[mseverin]

I'm really stuck. The events table has over 100,000 lines in it and even running in safe mode I am unable to purge the events.

I really need a way to access the H2 database outside of Mango so I can manually purge the table.

Mango is running on a Linux box with command line only.

Any help would be appreciated as Mango has been down for over a week now.

Hi Mseverin

Edit:

By the looks, you are running the script with an argument. What you need to do is edit the script and add -webAllowOthers to the last line of code.

Hello,

Yes, I was running it like ./h2-web-console.sh - webAllowOthers.

I modified the h2-web-console.sh and added -webAllowOthers to the end of the file but I still get the same result...

(Web Console server running at http://127.0.1.1:8081 (only local connections).

I just edited my h2-web-console.sh file as such:
java -cp ../lib/h2*.jar org.h2.tools.Server -webAllowOthers -web -webPort "$H2_PORT" -baseDir "$MA_HOME"/
Save and run it and get the following :
Web Console server running at http://192.168.0.251:8081 (others can connect)

When I modified my h2-web-console.sh like yours, I can now get to the Login screen but then I get

You have the incorrect JDBC URL and user and pass. Please check here for the correct settings https://help.infiniteautomation.com/about-the-h2-database

I can't connect the same as the example because the database is on a different server from where I'm running the web browser so I get the message "Database /opt/mango/mah2 not found". However if I modify the file to -tcp -tcpAllowOthers as the help link suggests, then I just get "This page isn't working.

@mseverin the input on the page expects the local path to the db corresponding to the machine you are accessing. In later versions of Mango this is mah2.199, check the filename of the h2 dB file on your Mango machine and use the full path to the h2 file minus the .db extension. I don’t think you want the tcp url, use the file:// style.

Thanks for the reply.

I have finally been able to connect.

The solution was to change my h2-web-console.sh back to -webAllowOthers

and my JDBC URL to jdbc:h2:/opt/mango/databases/mah2.199
