Master your CATIA and ENOVIA assets: Specialized control for DSLS

Dassault Systèmes’ CATIA and 3DEXPERIENCE platform are the backbone of aerospace and automotive engineering.

These tools use the DSLS (Dassault Systèmes License Server), a complex, proprietary manager that requires specialized monitoring to prevent costly compliance gaps and “denial of service” events.

OpenLM is the industry standard for DSLS management, offering deep integration that goes beyond basic logging to handle the intricacies of Dassault’s licensing model.

What is DSLS: Introducing Dassault Systèmes License Server

DSLS (Dassault Systèmes License Server) is a proprietary system that manages concurrent access to Dassault software like CATIA and SIMULIA. It hosts a shared pool of floating licenses, dynamically allocating keys to users upon launch and reclaiming them when the session ends. Designed to replace the legacy LUM system, it binds entitlements to specific server hardware to strictly enforce compliance and optimize network utilization.

All about Datamine licensing schemas

DSLS is known for its strict enforcement and complex “User Group” configurations. It manages high-value assets where a single seat can cost tens of thousands of dollars.

Complex consumption: Licenses are often consumed by “Trigrams” (feature codes) that are difficult to decipher manually.
Offline/borrowing: DSLS allows users to extract licenses for offline use. These licenses are invisible to many standard monitors, leading to “ghost usage” where licenses are unavailable but not actively used.
License release issues: It is common for DSLS licenses to “hang” after a crash, requiring manual intervention to release them back to the pool.

OpenLM’s solution for DSLS optimization

OpenLM interacts directly with the DSLS binary logs and query tools to provide a real-time, granular view of your engineering environment.

OpenLM capability	Value for DSLS licenses
Real-time license visibility	Instantly see which engineer is consuming which CATIA configuration (e.g., HD2, AL2). OpenLM decodes the cryptic “Trigrams” into human-readable product names.
Offline license monitoring	Track licenses that have been extracted for offline use. Know exactly when they are due to return, preventing surprise shortages when field engineers return to the office.
Group-based permission analysis	DSLS uses complex user groups (rules) to restrict access. OpenLM validates that these rules are working effectively, ensuring expensive simulation licenses are reserved for the right specialists.
Token analysis	If you are using the token-based model for Dassault, OpenLM tracks token drawdown rates to predict exactly when you will run out of capacity.

OpenLM advantages for DSLS usage monitoring

Legacy and modern support: OpenLM supports both the modern DSLS and the legacy LUM (License Use Management) often still found in long-running aerospace programs.
Project chargebacks: Allocate the massive cost of CATIA licenses to specific vehicle programs or aircraft projects based on actual hours flown.
