Summary

Reprise License Manager (RLM) allows administrators to reserve GibbsCAM licenses for specific users or groups. License reservations ensure that designated users always have access to the licenses they need, even when all other floating licenses are in use.

This article explains how to configure license reservations using the RLM options file.

TABLE OF CONTENTS

Overview

By default, all available GibbsCAM network licenses are shared among all authorized users.

License reservations allow administrators to dedicate one or more licenses to:

  • A specific user

  • A group of users

  • A specific computer (host)

  • A group of computers (host group)

Reserved licenses remain available only to the designated user or group and cannot be checked out by other users while reserved.

Before You Begin

Before configuring reservations:

  • Ensure you have administrative access to the Network License Server.

  • Locate the GibbsCAM RLM options file.
    See RLM Options File Reference NLO

  • Back up the options file before making changes.

  • Verify the exact username, hostname, or group name you intend to reserve licenses for.

Reserve a License for a Specific User

Open the RLM options file and add a RESERVE statement.

Example:

RESERVE 1 gibbscam USER jsmith


This example reserves one GibbsCAM license for the user jsmith.

If that user is not currently using the reserved license, it remains unavailable to other users.

Reserve Licenses for a User Group

If you have already created an RLM user group, you can reserve licenses for the entire group.

Example:

GROUP Engineering jsmith mbrown tlee


RESERVE 3 gibbscam GROUP Engineering


This configuration reserves three licenses for members of the Engineering group.

Any member of the group may use one of the reserved licenses.

Reserve Licenses for a Computer

You can also reserve licenses for a specific workstation.

Example:

RESERVE 1 gibbscam HOST CAD01


This reserves one license for the workstation named CAD01.

Apply the Changes

After modifying the options file:

  1. Save the file.

  2. Restart the GibbsRLMServer service, or use the RLM Web Administration interface to reread the options file if supported.

  3. Verify that the updated configuration loads without errors.

Verify the Reservation

  1. Open the RLM Web Administration interface.

Default address:

http://localhost:5054


  1. Review the server status and log messages.

  2. Confirm that the reservation has been accepted.

  3. Verify that the designated user can successfully obtain a license.

Best Practices

  • Reserve licenses only when necessary.

  • Reserve the minimum number of licenses required.

  • Use groups instead of individual users whenever possible to simplify administration.

  • Document all reservations.

  • Periodically review reservations to ensure they are still required.

  • Remove reservations for users who no longer need dedicated licenses.

Troubleshooting

Problem: Reserved User Cannot Obtain a License

Possible Causes

  • Username in the reservation does not match the login reported by RLM.

  • Reservation references the wrong feature name.

  • Options file contains a syntax error.

  • License server has not reloaded the updated configuration.

Resolution

Verify the username, review the reservation syntax, reload the options file or restart the license server, and confirm the configuration loaded successfully.


Problem: Other Users Cannot Use Available Licenses

Cause

Too many licenses have been reserved.

Resolution

Review the reservation configuration and reduce the number of reserved licenses if appropriate.


Problem: Reservation Does Not Appear to Work

Possible Causes

  • The options file was not reloaded.

  • The reservation syntax is incorrect.

  • The referenced user or group does not exist.

Resolution

Review the RLM server log for configuration errors and verify the reservation entries.

Expected Result

The specified users or groups receive priority access to the reserved GibbsCAM licenses while remaining licenses continue to be shared among other authorized users.
