Time to Talk about Timeouts in the Reprise License Manager (RLM)

Technical article on timeouts in the Reprise License Manager

There are two types of timeout events in RLM: connection timeouts, and idle timeouts. Let’s dig into each of them a little bit deeper.

Connection Timeouts Time's Up

Connection timeouts occur when a client application takes too long to connect to one or more RLM license servers. Users can change the default connection timeout value from 10 seconds to as low as 5 seconds by setting an environment variable. If set to a negative value, the connect timeout will be its absolute value, and if any particular server connection times out, no further attempts will be made to that server. If set to a positive value, a connection will be attempted to the server even if it timed out on the last attempt. The latter example is the default behavior in RLM.

Skipping over License Servers

RLM also keeps track of which license servers in its license path list have an ISV’s server running on them. If either there is no ISV line for that ISV in a local license file, or an attempt is made to check out a license from a server and the RLM server returns a status indicating that this ISV is not present, then the server is flagged as not having that ISV server.

In a multi-server environment, it doesn’t make sense for an application to repeatedly attempt checkouts from servers that are known not to be serving its licenses. So, application developers may choose to “skip” these license servers. Note that by default, RLM will attempt all operations on all servers.

Idle Timeouts and Heartbeats

Most users want the license server to reclaim licenses from applications that become idle for too long. This ensures maximum utilization of floating (shared) license pools.

The RLM license server expects to hear from client applications periodically as a way for applications to tell the server that they are still active. Normally, this is done by sending “heartbeats” from clients to the server either automatically or under the direct control of the application itself.

Some software vendors may decide to inform the server that an interactive application is idle while waiting for user input. This allows the application’s license to be reclaimed by the server when the application waits too long for user input. When the user eventually “wakes up” the formerly idle application, it will attempt to reclaim any lost licenses from the server.

When licenses are timed out by the server, they are essentially checked back into the pool for use by others.  This event can be recorded in a server report log, if desired.

User Control of Idle Timeouts

An end-user can specify a TIMEOUT value for any idle license. If the license remains idle for this amount of time, the license server performs an automatic check-in of the license and informs the application (if it is still running).

Software vendors can set a MIN_TIMEOUT keyword in a license that specifies the lowest value that an end-user can set for the timeout value of a license. If not specified in the license, the RLM default minimum of 3600 seconds (1 hour) is used.

FOR IMMEDIATE RELEASE: August 24, Houston, Texas

Lanner Group, the business process improvement and simulation software specialist has included Reprise Licensing Manager as standard for all users within its latest release of WITNESS Power with Ease 2.01. It follows the successful introduction of WITNESS software incorporating flexible license fulfillment with Ford Motor Company.

The latest release of WITNESS Power with Ease 2.01 includes a number of enhancements to the award-winning WITNESS system, and in partnership with Reprise Software, Inc. it now includes Reprise License Manager (RLM) networking licensing.

Lanner Group’s initial deployment of its WITNESS program integrating RLM was with Ford Motor Company.  The system proved adaptable and reliable and has led to the as standard inclusion of the licensing mechanism in the latest issue of WITNESS.

The incorporation of RLM into WITNESS simulation software allows licenses to be easily booked out from a network license on to a small portable computer or laptop providing the flexibility to work off the network as needed.

RLM is available for all network installations of WITNESS and for hardware locked stand-alone installations.  Further advantages of this new system are options for automatic web activation of licensing, making this process quicker and easier.

“We’re delighted with the simplicity and agility of the Reprise Licensing system,” says Lanner Group director of business development, Americas, Mandy Tague. She continues, “By integrating Reprise Licensing into WITNESS simulation software, Lanner Group is offering the market a uniquely agile and flexible system that gives a significant reduction in cost and time within the license fulfillment process.

“Reprise License Manager increases end-user customer satisfaction through the use of easy-to -implement, flexible license terms automatically included with software shipped to end users,” she concludes.

“Lanner Group’s license management requirements are similar to those of other companies in the simulation and modeling software industry, demanding a robust, powerful, yet affordable license manager,” stated Matt Christiano, CEO of Reprise Software. “We are proud that Lanner Group recognizes the flexibility, simplicity, power and value of the Reprise License Manager and look forward to continuing a long and mutually beneficial relationship between the two companies.”

Lanner Group also plans to roll out RLM with its law enforcement simulation, PRISM, and pharmaceutical simulation, Px-SIM, range of products in the near future.

The release of WITNESS Power with Ease 2.01 is part of a series of updates to improve the flexibility, power and ease-of-use of WITNESS software. Development objectives are set with the end user in mind, by consulting directly with WITNESS customers through client service reviews, site visits, and other informal conversations about what improvements customers would most like to see in the software.

Over the past two years Lanner Group’s development team has added built-in Quick 3D capability to WITNESS software.  This ability tracks and optimizes energy consumption and a host of other improvements to enhance user experience of WITNESS. This momentum continues with the release of WITNESS Power with Ease 3.0 later this year.

Network Intelligence Enabled – Tektronix Licenses the Reprise License Manager (RLM)

Summary: The Reprise License Manager provides a win-win solution by ensuring Textronix’s customers that they have enough licenses to satisfy their business requirements and, at the same time, that they are not paying for more licenses than they need. Also, the license manager protects  intellectual property from unauthorized use while increasing overall revenue as customers purchase all the licenses they need.

Tektronix selects RLM

Network operators today are faced with many challenges that impact their businesses – more competition, technology challenges, and a more demanding customer base. Many network operators have been caught off-guard and are searching for viable, cost-efficient solutions that will mitigate these challenges and enable all facets of their business to excel. At Tektronix Communications we develop Network Intelligence Solutions to help fixed, mobile and next-generation operators around the world better manage their networks, services and customers by providing them with accurate, real-time (and historical) information that can be leveraged by multiple departments such as customer care, product planning, network operations, network traffic and engineering, and more.

To be able to meet the constantly changing network demands and growth as well different operator sizes and requirements, we introduced a new innovative Applications Platform, IrisView. As the framework behind the Network Intelligence portfolio, IrisView provides a seamless user experience for all applications within the framework­regardless of the underlying data source.

Such flexibility required the embedded power of a license manager platform to enable the dynamic change, update and packaging of customer tailored solutions using different IrisView modules. Using the IrisView embedded license manager, RLM from Reprise Software, we were able to creatively price, package, and bundle products for broader and deeper operator’s market penetration whether it is on the mobile or fixed side. To meet emerging markets demands, we were also able to quickly create corresponding product packages to better serve these markets. With the license manager we were also able to offer our customers the use of IrisView applications trials or evaluations. Such trials enabled shorten acceptance cycles and generated interest in our new product features and upgrades.

In summary, the IrisView license manager provides a win-win solution by ensuring our customers that they have enough licenses to satisfy their business requirements and, at the same time, that they are not paying for more licenses than they need. In addition, the IrisView license manager protects Tektronix Communications intellectual property from unauthorized use while increasing overall revenue as customers purchase all the licenses they need.

How to License Server-based Software

Consider your options
The usual licensing strategy for server software is to lock it to a physical host. This provides some degree of protection from installing and running on multiple hosts, but it does not necessarily represent the optimal approach in terms of maximizing your revenue or customer satisfaction.

What’s missing?
First, there’s the notion of scaling. Do you really want to charge the same price for every site? You need some way to charge more when your software is used more.  Perhaps you can sell multiple node locked servers to larger sites, or even charge relative to the number of cores on the machines, the rationale being that there is the potential to get more use from machines with more horsepower.

Float your server licenses

If you want your customers to have the flexibility of installing and using your server on many machines without having to license them separately, perhaps you should use a floating license manager that ensures that no more than a predetermined number of concurrent server copies can run at the same time. With floating licensing, you issue a license key with a count, and lock only the license server, not each user node.

Size matters
Another approach could be licensing by some other scaled metric: how many records can be maintained in the database, a count of named users, etc.  Each of these metrics can be encoded into a license key, allowing the server software to know when it starts what level of service to enforce based on the license key scaling parameters. A single version of your software could then enforce the appropriate size limits on a site by site basis.

Using a license manager, such as RLM, could also give you even more control of how your software behaves within a virtual machine.  You could even license by platform or by the site’s timezone.

In any case, using a license manager gives you the freedom to change with your license policies.
