Access control box:
You may reserve models and display the file history.

Reservation of models

A model (or an UDx) beeing opened for write access will be reserved automatically for the respective user and thereby closed to write access for any other user. Granting write access to only one user at a time is a protection against unintentional overwriting of a model by several users.

Clicking on the parameter 'keep write access' while closing or saving a model or terminating EUKLID Design will preserve the model reservation, even if the model is no longer loaded. This reservation mode for a longer term makes it possible to perform greater changes to a model without being disturbed by other users.

A file containing all reservations is located in the directory of the actual system configuration. Additionally a file ".<model_name>.lck" will exist in the directory of the model file during the reservation.

Model history

Every storage of a model gives the user the possibility to enter a comment, e.g. the reason and the kind of the last change. These comments will be added to the model history which is saved within the model. The action admin can display the model history of any EUKLID Design model. You may store the list as a text file.

 

The action 'admin'

You can only reserve model files which are not reserved by anybody else. A reservation can only be canceled by its initiator. As a precondition to do a reservation you need to have write access permission for the file 'lockinfo.lta' located in the actual system configuration (#/design_config or the directory set with the start option '-config_dir').

An administrator can do or cancel any reservation for himself or for other users. If a reservation for a model file is canceled by the administrator while the user is working on that model a message will be sent to him automatically. For these activities the administrator needs to have write access permission for the actual system configuration - in general the KONSYS-Administrator (konadm) will have this permission.

The dialog box

The list displays all reserved model files. Please click on a line to select it. Afterwards you may perform several operations using the buttons in the upper part of the dialog box.

Please use the filters to reduce the list:

Note: Within all filters a "*" (asterisk) can be used as a 'wildcard', except for the first character.

The buttons:

Via a separate dialog box you can generate, change or remove areas.
An example for such an area:
Name: 'home_smith'
Computer 'sgi_5' - path: /usr/home/smith
Computer 'sun_4' - path: /net/sgi_5/usr/home/smith
Computer 'pc_3' - path: f:\

Use the AQL function 'translate_filename' to define the area of files to be used. If this area has an entry in the file translation table the system will find the corresponding drive.
Example: translate_filename ("f:\\tests\\tmp\\std.mod", "pc_3")
The model file 'std.mod' will be searched on drive 'f' of the computer named 'pc_3'.
