Validate a simulation¶

Validating checks that a simulation is intact and meets a server’s requirements, before you push it. For the concepts behind validation, see Validation.

Validate against a server¶

simdb simulation validate SIM_ID
simdb simulation validate REMOTE SIM_ID    # name a specific remote

A validation successful message means the simulation is ready to push.

Common failures and fixes¶

A data source is missing or changed¶

Validation recomputes the checksum of every input and output and compares it to what was recorded at ingest. A mismatch (or a missing file) fails validation.

Fix: restore the file, or re-ingest the simulation from an updated manifest so the recorded checksums match the current data.

Missing required metadata¶

A server can require specific metadata. See what it requires:

simdb remote schema -d 10

Fix: add the required fields. For a not-yet-pushed local simulation you can add metadata with simdb simulation modify SIM_ID --set-meta NAME=VALUE, or correct the manifest and re-ingest. See Ingest and manage.

Server-side validation¶

Servers can also validate automatically on upload (checksums, metadata schema, and optional file-content validation such as the IDS validator). This is controlled by the server’s [validation] and [file_validation] settings; see Configure validation.
