The MultiServer feature enables a personal computer to have cadett ELSA workstations for multiple servers installed in parallel, without conflicts. Even a local installation can be present simultaneously.

 

No re-registrations or other special means are needed. The user simply select the appropriate shortcut, and thereby start a cadett ELSA client for the appropriate server.

 

The limitation for this new capability is that only cadett ELSA R38 and later is supported. Earlier versions cannot coexist in the way described above, not even with an R38 or newer installation. On the other hand, cadett ELSA R37 that was the final version not supporting MultiServer was discontinued already in 2018, so this limitation is currently hardly of any significance.

 

There are a number of practical applications for the MultiServer capability. A couple of examples are highlighted below:

 

•A test server can be used in parallel with a production server, where a new version of the software, a new customisation or similar is tested separated from the production server. The same workstation computers can be used for both servers.

 

•A local installation can coexist with one or many workstations for servers on the same personal computer without conflicts and without need for batch files to switch from one way of running the software to the other.

 

One limitation that however exists, is that you can have only one cadett ELSA server installation on each Windows Server (physical or virtual).

 

The figure below shows two shortcuts in parallel, which is a typical example of how MultiServer can be used, in its most simple form. The one to the left is for a network installation and the one to the right is for a local installation.

 

 

The names of the shortcuts are made up in the following way:

 

cadett ELSA (Drive letter) WS[ws code]

 

The drive letter within parenthesis refers to where a network installation of cadett ELSA is located. If multiple cadett ELSA servers are used, they need to be separated with different drive letters.

 

Example:

 

•Server 1:

X:\ELSA

 

•Server 2:

Y:\ELSA

 

“C” is used to symbolise a local installation, regardless of whether the software is actually installed on drive C: or not. (For example, it is perfectly possible to install a local cadett ELSA on a local D: drive).

 

The WS-code (workstation code) is used in the same way as when only one server is present.

 

•0 is used for a local installation.

•1-9, a-z and A-Z are used for conventional workstations in network installations.

 

Another feature is the possibility to have so-called “dynamic workstations”. In that case, the shortcut is neutral and the workstation code is assigned dynamically each time the software is started.

 

A dynamic shortcut like that is shown in the figure below. The workstation code is simply specified with an underscore character.

 

 

Please refer to the topic listed below for a detailed description of dynamic workstations.
