When do I need the RLM License Server?

The Reprise License Manager product is capable of supporting many license types. Some are appropriate for standalone, single-user licensing models and others are used to support more complex network licensing and pricing scenarios. Determining when a license server must be installed is not always clear.

So, let’s spend a few minutes talking about the various jobs a license server performs, and when it is needed to support various license types.

Uncounted v. Counted Licenses

The biggest factor that determines whether a license server is required is whether licenses are counted or uncounted.  Counted licenses require a license server because it must “count” concurrent licenses. Counted licenses are used whenever the ISV wants to limit or record concurrent license usage. Counted licenses can be identified by a positive integer in the “count” field of the license.

Uncounted licenses, on the other hand, do not require a license server because there is no need to count usage. Uncounted licenses can be identified by the word “uncounted” or or the number “0” in the license count field of the license. Each uncounted license must be node-locked to a hostid. For ease of administration at larger sites, uncounted licenses for multiple computers may reside in a license file that is managed by a central license server, but this is not required.

The other license type that does not require a license server is the “single” license type. This is also a node-locked license, but it can be used by only one user at a time (concurrent count of “1”). The enforcement of “single” licenses is done via file locking, not by license servers.

The RLM License Server

The basic job of the RLM License Server is to service license requests from RLM-enabled client applications over the network. Based on the needs of the application, the license server redirects license requests to the ISV-specific license server which actually grants or denies the request based on what is specified in the license and on the current usage conditions.

License servers also manage “roaming,” named-user, and token-based licenses. They manage held and shared licenses, and offer an admin interface, diagnostic tools, and are responsible for writing debug and report logs.
