Using CoreManager

Checkout and build the code

• Create a work area based on nightly release NT23-02-18
• Checkout the develop branch of these packages
  • https://github.com/DUNE-DAQ/genconfig
  • https://github.com/DUNE-DAQ/oks
  • https://github.com/DUNE-DAQ/oksconfig
  • https://github.com/DUNE-DAQ/oksdbinterfaces
  • https://github.com/DUNE-DAQ/oksutils
• Checkout the gcrone/no-dal branch of these packages
  • https://github.com/gcrone/dbe
• Checkout the gcrone/Resource branch of these packages
  • https://github.com/gcrone/appfwk
  • https://github.com/gcrone/dunedaqdal
  • https://github.com/gcrone/coremanager
  • https://github.com/gcrone/cpuburner
• Update the sourcecode/dbt-build-order.cmake file to build the OKS packages (okssystem,oksdbinterfaces,oks,genconfig,oksutils,oksconfig,dbe and dunedaqdal) and coremanager before appfwk and cpuburner after appfwk.
• Set the environment variable TDAQ_DB_PATH (see below). This must be done before building so that the code generation from OKS schema can find the schema of included packages.
• dbt-build the code.

Set TDAQ_DB_PATH environment variable

TDAQ_DB_PATH is a a colon : separated list of paths to search for OKS configuration files. Currently to find all the necessary schema files it should include all the packages that have schema. In the sourcecode directory where you cloned the packages. If you want to keep your configuration data separate, you can add a directory of your choice to the end of the list:

 export TDAQ_DB_PATH=${PWD}/dunedaqdal:${PWD}/cpuburner:${HOME}/configs

Create an OKS configuration

Copy the file cpuburner/data/burn.data.xml and edit it with the OKS database editor dbe_main. See the notes in the README in the gcrone/coremanager branch of dunedaqdal.

Create a JSON configuration for nanorc to boot

Create a session directory for the configuration with an empty data subdirectory (nanorc will complain if it can't find the data directory).

 mkdir -p burn/data

Add a boot.json like the following to the session directory:

        "burner-1": {
