What Data for This Category Looks Like
The data for this category comes from formula and process libraries, raw material batch records, reactor DCS systems, weighing systems, LIMS laboratory management systems, and warehouse systems of coating, resin, additive, agrochemical intermediate, and specialty chemical enterprises. Daily documents include batch production instructions, feeding review sheets, reaction process records, cleaning validation records, test reports, deviation and change orders. Data updates trigger per batch production and each key process step. Fields include raw material batch number, reaction temperature, feeding amount, cleaning validation results, and others. There are no unified fixed units; values follow the field definitions of the corresponding business system.
Constraints Imposed on Deployment and Upgrade
The multi-batch, multi-step production characteristics of this category require deployment to support associating multi-system data by batch dimension. It also requires compatible access to scattered heterogeneous data sources. Data updates triggered per batch require upgrade processes to ensure atomicity of data synchronization. This prevents abnormal data from a single batch from affecting the entire workflow. Business requirements for formula confidentiality and cleaning confirmation require strict control of data access permissions during configuration. It also requires support for specialized retrieval of cleaning records and cross-contamination risks. Mixed entry of multiple document types requires deployment to adapt to parsing production documents of different formats. This avoids field matching errors.
Configuration Rules
This page’s configuration rules apply to FastGPT v4.17.0.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
DB_MAX_LINK | 100–200 connections | Adapt to multi-system data association queries generated per batch production, avoid exhausting database connections |
MONGODB_URI | Configure per the cluster address of the enterprise's LIMS and DCS systems | Store mixed structured and unstructured data such as batch-level reaction process records and test reports |
REDIS_URL | Local Redis cluster address, port set to 6379 | Cache frequently accessed formula and process library data, reduce latency for multi-batch queries |
STORAGE_S3_ENDPOINT | Access endpoint of the enterprise's internal object storage | Store original files of production documents such as cleaning records and feeding review sheets |
FE_DOMAIN | Secondary domain for internal enterprise access | Configure the frontend access address, adapt to internal network permission control |
ROOT_KEY | Generate per the enterprise's internal key specification | Control the highest permission access to the system, prevent unauthorized personnel from modifying traceability configurations |
Three Common Misconfigurations
- A connection timeout prompt appears, returning status code 504. The cause is failing to adjust the
DB_MAX_LINKvalue for multi-system data association queries, leading to exhausted database connections that cannot respond to batch queries. - The frontend page cannot be accessed via HTTPS, with an invalid certificate prompt. The cause is failing to bind the certificate file generated by mkcert in the
FE_DOMAINconfiguration, and failing to correctly configure the internal HTTPS access endpoint. - Team members cannot access the deployed traceability program, with a permission denied prompt. The cause is failing to assign team access roles through the permission system configured by
ROOT_KEY, and failing to complete permission mapping for internal teams.
How to Verify Successful Configuration
- Perform a single-batch data synchronization test. Check that fields pulled from the DCS and LIMS systems match production documents exactly, then adjust association rules until no fields are missing.
- Access the address configured in
FE_DOMAIN. Verify that the HTTPS connection works normally, with no security warnings for the certificate. - Create a test team account, then attempt to access the deployed traceability program. Confirm that permission assignments take effect.
- Trigger a batch data synchronization task. Check that the database connection count does not exceed the
DB_MAX_LINKconfiguration range, with no connection timeout error messages.
