B.index Server 3 Link May 2026

In the architecture of Bentley’s infrastructure design software, the "b.index" component is a critical background service often misunderstood by general IT administrators but essential for the performance of Computer-Aided Design (CAD) operations.

Here is a complete technical look into the Bentley Index Server (b.index), its architecture, function, and troubleshooting. b.index server 3

C. Sheet Indexing

In ProjectWise, creating a "Set" (a collection of drawings for plotting) relies on the index server to determine sheet boundaries and named models within a DGN file. Linux (Ubuntu 22

3. Key Functions

2. Real-Time Index Mutation

Unlike its predecessors which required batch rebuilds, b.index server 3 introduces live segment merging. New documents can be indexed instantly while older segments are optimized in the background—zero downtime. Isolation: In high-security environments

Prerequisites

• Linux (Ubuntu 22.04+, RHEL 9+), Windows Server 2022, or macOS for development.
• Minimum 8GB RAM, 4 CPU cores, 50GB free disk.
• Java 17+ or Go runtime (depending on distribution—most common is the Native Go Build for v3).

6. Security Considerations

Because the Index Server effectively "opens" every file that enters the system, it is a potential vector for macro-based viruses (though rare in DGN format) or file-corruption attacks.

• Isolation: In high-security environments, the Index Server is often placed on a dedicated virtual machine, separate from the Database Server and the Web Server.
• Permissions: The service account running the b.index service should have "Read" access to the file storage vault but should generally be restricted from "Write" access to prevent accidental modifications.

Exit codes

• 0: success (all items indexed or skipped)
• 1: partial success (some items failed)
• 2: server unreachable or invalid args
• 3: unexpected internal error
