Source code repository

Xconf consist of two web applications - Xconf dataservice and Xconf admin. Xconf DataService is the app that the STBs talk to. Xconf Admin allows humans to enter all the information necessary for Xconf to provide the correct information to STBs. This repo contains the source code for both the applications -  https://github.com/rdkcentral/xconfserver 

Software Requirements (Reference setup)

Installation of dependencies

1. Install Java JDK

Java JDK version should be 8.  Get the supported version from Oracle or use the OpenJDK packages.

...

Check your installation using the command : java  -version

2. Install Maven (Version 3.6.0)

Maven version should be 3 +. 

...

• sudo apt update

• sudo apt install maven

• Check the installation using : mvn -version

3. Download xconf server code

We can download the latest xconfserver code from https://github.com/rdkcentral/xconfserver. The latest version of the code is available in main branch.

• Create a folder : mkdir xconf

• Step into the folder cd xconf/

• git clone https://github.com/rdkcentral/xconfserver.git -b main

4. Install and setup Cassandra(Version 3.11.9)

Install Cassandra

To install Cassandra , follow the below steps

• Download the tarball file for the version 3.11.9 : 

  wget -c https://archive.apache.org/dist/cassandra/3.11.9/apache-cassandra-3.11.9-bin.tar.gz  
  

• Unpack the tarball :  
  tar -xvf  apache-cassandra-3.11.9-bin.tar.gz
  
  

• Step into apache-cassandra-3.11.9 folder :

  cd apache-cassandra-3.11.9
  
  

• To start Cassandra, run the following command

  sudo bin/cassandra
  
  

• To verify that Cassandra is up and running, enter the following command :

  bin/nodetool status

Configure Cassandra

Note :  For the next step, make sure that python is installed. Because cqlsh is python based command line tool. If python is not installed , use this command : sudo apt install python2.7

...

• To exit from cqlsh prompt, we can use the command : quit

Configuration and Service startup

1. Start Cassandra Service

• To start an Xconf application, start the Cassandra server by executing the following commands:  
  

...

• Status of xconf server can be verified by using  the command

          bin/nodetool status

2. Configure and Start Application Services

Build and run steps mentioned below is based on these steps - https://github.com/rdkcentral/xconfserver#run-application.

a. Build Project

• Go to the xconf-server folder and run the following command to download all dependencies.

...

          mvn clean install

b. Configure Angular Admin UI

• For first time application deployment, create a "service.properties"  file under the path xconfserver/xconf-angular-admin/src/main/resources/service.properties with the following contents. The sample service.properties file will be available in xconf-angular-admin/src/test/resources/service.properties, the below content is taken from there and modified with change in cassandra port.

...

If the user wants only read permissions ,then enter username and password for the login are user and user respectively.

c. Configure DataService

• For first time application deployment, create a "service.properties"  file under the path xconfserver/xconf-dataservice/src/main/resources/service.properties with the following contents. The sample service.properties file will be available in xconf-dataservice/src/test/resources/service.properties, the below content is taken from there and modified with change in cassandra port.
  

  cassandra.keyspaceName=demo cassandra.contactPoints=127.0.0.1 cassandra.username= cassandra.password= cassandra.port=9042 cassandra.authKey= dataaccess.cache.tickDuration=60000 dataaccess.cache.retryCountUntilFullRefresh=10 dataaccess.cache.changedKeysTimeWindowSize=900000 dataaccess.cache.reloadCacheEntries=false dataaccess.cache.reloadCacheEntriesTimeout=1 dataaccess.cache.reloadCacheEntriesTimeUnit=DAYS dataaccess.cache.numberOfEntriesToProcessSequentially=10000 dataaccess.cache.keysetChunkSizeForMassCacheLoad=500 dataaccess.cache.changedKeysCfName=XconfChangedKeys4

  
  

• Step into xconf-dataservice folder
   

      cd ~xconf/xconfserver/xconf-dataservice

...

To launch the application go to http://<XCONF-SERVER-IP>:19092/queries/environments .  To verify, add an entry in the environments tab of the xconf admin application and check whether the same is updated here in data service.

• Data Service Endpoints

  
  The endpoints available in data service is listed and described here - https://github.com/rdkcentral/xconfserver#endpoints

...

NOTE: To run the Admin UI and data service applications in background start jetty server as follows: nohup mvn jetty:run &

3. Expected build or Issues

1. The below exceptions are observed during the mvn clean install . This is an exception from unit test , but the tests will run successfully. The execution may stall for some time but the build will be successful and the application can be launched successfully. So it can be ignores as well.

...

Solution : This exception can be resolved by copying the .so file to the path /usr/lib.

Configuration and Validation of services

Admin UI Common Configuration

Below steps will affect all the features in xconf system and should be configured after initial setup. Go to the steps given in site navigation step and press on create button to create new entries.

Define Environments

Feature Validation(RFC)

Configuration

RDK Feature control configuration can be added by adding below 2 sections

...

Verification

1. Verification of feature and feature rule via test page.

}

Client end verification (RPI)

Verification and setup from RPI

Feature Validation (LogUpload)

Configuration

1. Create upload repository via DCM->Upload repository -> Create.   Here we can add where to configure the log upload, ie the upload url and its protocol.

...

5.  Edit the Log upload Setting (Create schedule & Add the upload repository created beforehand).

Verification

1. Verification of log upload settings test page.

...

    "urn:settings:VODSettings:SRMIPList": null

}

Client end verification (RPI)

Feature Validation (Telemetry)

1. Telemetry configuration can be done by adding a permanent profile which contains below objects
   1. Upload repository
   2. Profile options (Header, content, frequency etc.)
2. Creating a targeting rule which is basically mapping the profile to a set of MAC/IP/Device etc.

Configuration

1. Create a permanent profile Telemetry - > Permanent Profiles -> Create

...

Verification

1. Verification of telemetry test page.

...

        "uploadRepository:uploadProtocol": "HTTP"

}

Client end verification (RPI)

Feature Validation (Firmware update)

Configuration

1.  Firmware config can be created via Firmware - > Firmware Configs -> Create. Here we can define the file name and version of the image/firmware that need to be downloaded to the CPE device. The models that we defined in Common → Models section will be available here, We can select the needed models by clicking on it.

...

Import and Export Feature

We can import and export all the configuration data from the UI itself.  This feature can be primarily used for transferring the configuration data from one xconfserver setup to the other one. The export and import
