Figure 2356: Specification of the cadett ELSA main directory
In the next step of the installation, you specify the physical main directory of cadett ELSA and the mapped drive letter used on the workstations.
Please note that the physical directory where cadett ELSA will be placed is not identical with the path that the workstations will use. This is because the workstations access cadett ELSA using a drive that is mapped to a shared directory on the server.
You will therefore now specify both the physical directory and the drive letter that will be used.
Example:
From the workstation’s point of view cadett ELSA is located in
X:\ELSA
X:\ on the workstations represents the directory
C:\CADETT
on the server.
The directory C:\CADETT on the server is shared. On the workstations it is mapped as X:.
The physical directory in which cadett ELSA hence should be installed is
C:\CADETT\ELSA
The mapped drive letter for the workstations is
X:
It is possible to make a free selection of directory name for the cadett ELSA main directory (ELSA in the example above) but with the following restrictions:
•The directory from the workstation’s point of view must be located in a root (for example X:\).
•The directory name must follow the DOS83 convention, which means that it cannot contain more than 8 characters, no spaces and it may only contain the characters A–Z, 0–9, _ and -.
The directory name ELSA is recommended. There are no reasons not to follow that recommendation, but there are good reasons not to change it.
Remark
The shared directory that represents the root in which the cadett ELSA main directory ELSA is located – C:\CADETT in the example – does not need a name that follows the DOS83 convention. A name like “cadett ELSA” would work perfectly.
The selected drive letter does not have to be mapped on the server like on the workstations. The installation program will automatically create a so-called “substitute”. This means that the SUBST command is used to create a “virtual drive” connected to the directory that is shared with the workstations. In this way, the installation of cadett ELSA “looks the same”, when viewed both from the server and from the workstations.
Please note that all workstations must use exactly the same drive mapping, with the same drive letter. You must therefore select a drive letter that does not conflict with anything else for all workstations.
If the directory that you specify for sharing (C:\CADETT in the example above) does not exist, it will be created automatically by the installation program. The sharing of it on the server and the mapping of it on the workstations has to be done manually however. The installation program will not help you with that.
If the specified directory does not exist, a message will be displayed to inform you of that, before it is created.
Figure 2357: Message shown if directory does not exist
If you are updating an existing installation by installing in the same directory as the old installation was located in, it is wise to select the directory, not typing it. In that way you ensure you are really using the existing directory, which is important in order to simplify the update procedure.
If the directory that you specify, either by selecting it or by typing it, in fact does exist, a warning will be issued, as shown in the figure below.
Figure 2358: Warning issued if the specified main directory already exists
If you are updating an existing installation this is perfectly normal.
The text informs you that the main directory of the old installation will be renamed to create a backup, so that the new installation can be placed in a new directory with the same name as was used for the main directory of the old installation.
The next step is described in the topic that is listed below.
