Simulation on AODT does not go through: Need detailed steps of running simulation after setting up RAN digital Twin in AODT

Omniverse Developer Tools & Resources Developer Tools

We are getting ready to run simulations of RAN digital Twin using AODT. We are through the installation and other important steps such as:

→ Adding scene of a city

→ Adding RU, DU and UEs

→ Adding click house database

So, far we followed the steps as in link below:

Installation - NVIDIA Docs

Now, when we are at the stage of running the Simulation:

click the Generate UEs icon in the toolbar

It asks me to attach a worker and when I try to attach a worker for generating UE, I get the following error:

“Error creating database tables: fail to connect: Connection refused. Please check our database and connection.” followed by “Worker has lost connection”

I have attached screenshots of the dialog boxes as they open, in order.

We might be missing creating database appropriately in click-house docker ?

Can you guide me to fix these errors. Please share if there are more documentation to follow comprehensive steps?

Can you please do the following:

  1. Looks like the port 9000, which is needed by clickhouse. is occupied by some other process. To check it, can you please run
    docker compose stop clickhouse
    docker ps //Make sure there is no clickhouse service running
    netstat -tuplen | grep 9000 //Check if port 9000 is occupied
  2. If port 9000 is occupied, then you will need to stop the service that is utilizing the port
    a. Then restart clickhouse

Hi,
I followed the steps and found that the port 9000 is not occupied. However, I am still facing this issue.
Can you please guide me further to resolve this issue?

@k.wadhwa I am sorry to hear that you are still having trouble with this. I will say that in general, any connection issue is usually a network security / network permissions problem. Are you working on a corporate network? Do you have a network admin that you are working with to open these ports and to gain access? Have you disabled your anti-virus? Do you have a proxy server or a internal network traffic blocker?

However, for AODT, you should be posting in our dedicated forum for it at https://forums.developer.nvidia.com/c/accelerated-computing/aerial/674
