FAQPage Schema

How do I troubleshoot dt4acc container startup failures?▼

To troubleshoot dt4acc container startup failures, run diagnostics to verify container health, MongoDB readiness, and accelerator lattice data presence across Docker and Apptainer workflows.

Why does my EPICS or Tango twin container fail to start?▼

EPICS or Tango twin containers fail to start when missing BESSY II accelerator lattice data in MongoDB prevents initialization, requiring data import checks and environment verification.

Do I need MongoDB running before starting a dt4acc container?▼

Yes, MongoDB must be running and ready before starting a dt4acc container, as the startup validation checks for required accelerator lattice data stored within the MongoDB instance.

Does this container troubleshooting process work with Apptainer?▼

Yes, the troubleshooting process works with Apptainer and Docker deployments, providing reproducible environment verification and configuration path checks for HIFIS pre-built deployments.

What is the best way to verify missing lattice data in MongoDB?▼

The best way to verify missing lattice data in MongoDB is to run quick-start diagnostics that confirm database readiness and validate the presence of required BESSY II imports.

What to do when dt4acc container startup is not working?▼

When dt4acc container startup is not working, enforce startup prerequisites, validate container health, and apply step-by-step reproducible checks to restore the environment.
