ICONIX CASE products can share data (multiple users having concurrent access to diagrams and dictionaries in a shared folder) on a fileserver, detect collisions (when two users change the same item at overlapping periods of time) across a team of developers and provide other team project support (e.g. global name change across the network). This set of capabilities is referred to by the term "multi-user".

ICONIX CASE products can be installed on a fileserver, with a concurrent user limit (also called launch count) assigned to each module. The modules are then launched from workstations connected to the server. This allows a project to order a number of copies of each module based on the anticipated maximum number of concurrent users, rather than having a copy for each workstation. This capability is referred to by the term "multi-launch".

Occasionally, customers will think that a server-install (multi-launch) is necessary in order to get shared data (multi-user) capability. This is not the case. All PowerTools modules, whether they reside locally on the workstation or on the server, provide full multi-user support.

What are the tradeoffs between choosing a multi-user or multi-launch configuration? The only advantage to choosing a multi-launch configuration is cost, particularly in an environment where there are multiple users who will only need occasional access to the tools. In this case, the ability to set a per-module launch count can result in a significant savings, as the licenses can "float" across the network.

The risk of placing all copies on the server is, of course, that in the real world, servers sometimes go down. When estimating cost savings from a floating license, you should consider how reliable your network installation is, and factor in the possible cost of having your developers lose access to the tools in the event that server downtime occurs. Additionally, depending on the network and server configuration, users may experience some performance degradation if everything is running off the server. In most cases, the degradation is not severe, especially in higher-end environments that have fast servers and Ethernet networks.

For the above reasons, in the absence of severe cost pressure, ICONIX recommends keeping software installed locally and data shared on the server as the most optimal configuration. You should consider the above factors and make the best decision for your environment.
