Summary

The Reprise License Manager (RLM) options file is used to control advanced behavior of the GibbsCAM Network License (NLO) Server. It allows administrators to define rules such as user groups, license reservations, access restrictions, and usage limits.

This article provides a reference of the most commonly used RLM options supported in GibbsCAM deployments.

TABLE OF CONTENTS

Overview

The RLM options file is a plain text configuration file processed by the GibbsCAM license server.

It is typically used to:

  • Define user groups

  • Reserve licenses

  • Restrict license usage

  • Control license allocation behavior

  • Monitor or log license usage

Changes to the options file require a restart of the GibbsRLMServer service or a reload through the RLM Web Administration interface.

Create the ISV Options File

On the server, create a file named "gibbsnet.opt" here:

C:\Program Files\GibbsCAM\GibbsCAM NLO Server 2024

Basic Syntax Rules

  • One directive per line

  • Case-sensitive keywords

  • No quotation marks unless required for paths

  • Blank lines are allowed

  • Lines beginning with # are treated as comments

Example:

# Example RLM options file

GROUP Engineering jsmith mbrown tlee

RESERVE 3 gibbscam GROUP Engineering

Common RLM Directives

GROUP

Defines a group of users.

Syntax:

GROUP group_name user1 user2 user3


Example:

GROUP Engineering jsmith mbrown tlee



RESERVE

Reserves licenses for a user, group, or host.

Syntax:

RESERVE number feature USER|GROUP|HOST name


Example:

RESERVE 2 gibbscam USER jsmith

RESERVE 3 gibbscam GROUP Engineering



INCLUDE

Allows only specified users or groups to use a feature.

Syntax:

INCLUDE feature USER|GROUP name


Example:

INCLUDE gibbscam GROUP Engineering



EXCLUDE

Prevents specified users or groups from using a feature.

Syntax:

EXCLUDE feature USER|GROUP name


Example:

EXCLUDE gibbscam USER trainee01



HOST

Restricts license usage to specific computers.

Syntax:

HOST hostname


Used in combination with other directives such as RESERVE or INCLUDE.


HOST_GROUP

Defines a group of computers.

Syntax:

HOST_GROUP group_name host1 host2


Example:

HOST_GROUP CADStations CAD01 CAD02 CAD03



MAX

Limits the number of licenses a user or group can use simultaneously.

Syntax:

MAX number feature USER|GROUP name


Example:

MAX 2 gibbscam USER jsmith



TIMEOUT

Reclaims inactive licenses after a specified time.

Syntax:

TIMEOUT feature seconds


Example:

TIMEOUT gibbscam 3600


This example reclaims a license after 1 hour of inactivity.


NOLOG

Disables logging for a feature.

Syntax:

NOLOG feature


Example:

NOLOG gibbscam

Applying Changes

After editing the options file:

  1. Save the file

  2. Restart the GibbsRLMServer service
    OR
    Use the RLM Web Administration interface to reload configuration

  3. Verify the license server status

Verification

To confirm changes are applied:

  1. Open the RLM Web Interface:

http://localhost:5054

  1. Check:

    • License usage

    • Group definitions

    • Reservation behavior

    • Error logs

  2. Launch GibbsCAM on a client workstation and verify expected behavior

Troubleshooting

Options File Not Taking Effect

Possible Causes

  • Syntax error in file

  • Service not restarted

  • File not in correct directory

Resolution
Check logs in the RLM web interface and correct syntax issues.


Users Ignoring Group Rules

Possible Causes

  • Username mismatch

  • Incorrect feature name

  • Options file not loaded

Resolution
Verify exact usernames as reported by RLM and reload server configuration.


Licenses Not Available After Adding RESERVE Rules

Cause
Too many licenses reserved

Resolution
Reduce reserved count or review group assignments

Best Practices

  • Always back up the options file before editing

  • Use groups instead of individual users when possible

  • Document all changes

  • Apply changes during maintenance windows

  • Validate syntax before restarting the server

  • Avoid excessive reservation of licenses

Expected Result

The GibbsCAM Network License Server applies administrative rules defined in the RLM options file, enabling controlled and predictable license usage across the organization.
