Expand tab

You can define Alfabet Expand related attributes in this tab.

Required configuration for activation of full functionality:

• Test Web Application: Some functionalities in Alfabet Expand like, for example, review or reports and use of the ADIF assistants, open in a web interface. Enter the URL of a running Alfabet Web Application which shall be used to open the Alfabet user interface from within the Alfabet Expand application. The path must start with http:// or https:// and end with /.

  Server variables can be used to define part of the information as a variable with the value set in the Variables tab of the server alias configuration.

• Automatically generate ALFA_MM tables: Select the checkbox to activate update of the ALFA_MM_*_INFO object class tables at the end of each update of the meta-model via AMM file. By default the option is activated.

  The tables store the information about the current configuration of the Alfabet class model and should only be changed using this mechanism or the update option Meta-Model > Generate Meta-Model Information in the menu of Alfabet Expand.

Security related settings:

• Scan uploaded files for malware Select the checkbox to activate anti-virus check of all documents uploaded to Alfabet via the web interface. The whitelist and blacklist definitions configured in Alfabet Expand for allowed file types are also considered. This option is activated by default.

  The scan is performed via the anti-virus software installed on the server host. An anti-virus application with AMSI (Anti-Malware Scan Interface) support must be installed on the server host and AMSI must be activated for the operating system and the anti-virus application.

Settings for working with multiple Alfabet Expand instances in parallel:

If you are using multiple instances of Alfabet Expand in parallel with a connection to the same Alfabet database, you should set the following attributes. If the meta-model is changed in one of the instances of Alfabet Expand and the changes are saved to the meta-model, the users of the other Alfabet Expand instances will be informed via a message on the Alfabet Expand host that the meta-model has changed. Clicking the message opens a report in the center pane of Alfabet Expand that provides information about which change was made to the meta-model and the user that performed the change. The following configuration must be available in the server aliases of all involved Alfabet Expand instances:

• Track Meta-Model Changes: Select the checkbox.
• Tracking Period (seconds): Enter the interval for tracking changes to the meta-model in seconds.

Settings for direct meta-model update between databases: These settings activate upload of changes to the meta-model configuration via a direct connection between Alfabet Expand of a source Alfabet installation and the Alfabet database of a target Alfabet installation. This mechanism is not recommended for production environment. It should only be used for updating of test and solution configuration environments. The configuration is required in the server alias of the Alfabet Expand application in the source environment.

• Enable Master Database Configuration: Select this checkbox to activate direct meta-model upload to a target database.
• Alias for Meta-Model Design Master Database: Enter the name of the server alias configuration for connection to the target Alfabet database.
• Update from Master Database Mode: Select Complete Updates if you want the complete configuration to be taken over. Select Selective Updates if the person triggering the updates shall decide about which parts of the configuration to take over.
• File-Based Updates Permitted: Deselect the checkbox if you want to perform meta-model update exclusively via the direct connection. If you deselect the checkbox, you deactivate the Update Meta-Model functionality in Alfabet Expand for update of the meta-model configuration of the current database with the meta-model configuration stored in an AMM file.
