Main Areas of the Administration Tool¶
The Virtual DataPort Administration tool has three main areas: the menu bar, the Server Explorer and the Work Space.
The menu bar has the following menus:
File: it has the following submenus:
New: it has submenus to create any type of element: folders, data sources, views, etc.
Change password: it allows you to change your password.
Export database: to export the metadata of a database or a specific element of it.
Export: to export the metadata of the entire Server.
Import: to import the VQL statements stored in a file.
The section Exporting and Importing the Server Metadata explains how to use the dialogs “Export database”, “Export” and “Import”.
Jar management: to import extensions to the server. I.e. jar files containing custom functions, custom wrappers, etc. See section Importing Extensions.
Refresh: if there have been changes in the metadata of the Server, you must refresh the Tool to reflect these changes.
Disconnect: disconnects the Administration Tool from the Virtual DataPort database.
Database management: it allows managing the Virtual DataPort databases. See section Databases in Virtual DataPort.
Role management: it allows managing the roles of the Virtual DataPort users. See section Roles.
User management: it allows managing the Virtual DataPort users and their privileges. See more about this in the Administration Guide.
Server configuration: dialog to change the settings of the Server. See section Server Administration - Configuring the Server.
VCS management: dialog to change the settings of the Version Control Systems integration (VCS) of Virtual DataPort. See section Version Control Systems Integration
VQL Shell: tool to execute VQL statements. See section Using the VQL Shell.
Query Monitor: tool to monitor the queries that the Server is currently executing. See section Query Monitor.
Catalog search: tool to search elements in the Virtual DataPort server database. See section Catalog Search.
Invalidate cache: tool to invalidate the cache of several views at once. See section Invalidate Cache.
Manage statistics: tool to gather the statistics of several views at once. These statistics are used by the cost-based optimization process. See more about this in the section Cost-Based Optimization.
Trace viewer*: tool to load information about the execution of a query that was stored in a zip file using the Save button of the tab Query Results.
JMS listeners: dialog to manage the JMS listeners of the database you are currently connected to. See section JMS Listeners.
Admin Tool preferences: contains submenus to configure several aspects of the Administration Tool. See section Tool Preferences.
Reset layout: sets the layout of the Tool to its default state. That is, all the tabs go back to its default position.
Help has sub-menus to access the on-line help, the user manuals and a list of the existing functions and their syntax. See section Documentation and Online Help.
The Server Explorer lists all the databases of the Virtual DataPort server; and for each database, its data sources, base views, derived views, stored procedures, etc. These elements can be organized in Folders so they can be found easily. Using the Server Explorer, you can do, among others, the following actions:
Create new elements: right-click on a database or on a folder, click New and then, on the desired submenu.
Delete an element: right-click on the element and click Drop.
Copy and Paste an element: right-click on the element and click Copy. Then, right-click on the target folder and then, Paste. As there cannot be two elements with the same name, even if they are in different folders, you will have to provide a name for the new element.
Move an element to another folder: drag an element and drop it into another folder. You cannot move an element between two databases.
See the properties of an element: right-click on the element and click Properties. In this dialog, you can see information about the selected element such as owner, description, date of creation and last modification, etc.
Expand and collapse all the nodes of the Server Explorer: right-click on the database or a folder and click Expand all or Collapse all.
To add a prefix to several views and/or associations at once, select them, right-click them and click Prefix selected views/associations.
This option is useful when you create many JDBC base views from the same data source and you want to add a prefix to their name to distinguish them.
If you click Discover associations (only displayed when just JDBC base views are selected), the Server will analyze if in the database of the JDBC data source, there are foreign key constraints between the tables of the base views of this data source. If there are, the Tool will show a dialog that will allow you to create associations that mirror these foreign key constraints. The process of discovering associations works in the same way as when you discover the associations during the creation of JDBC base views (described in the section Creating Base Views from a JDBC Data Source). However, if an association is already defined, the Tool will not list it.
You can create a view from several views and, delete or move several elements at the same time by selecting these elements and performing the desired action. For example, to delete two views at the same do the following:
Hold the Ctrl key.
Click on these two views.
Right-click on one of them and click Drop.
Above the Server Explorer, you can find the Quick Search. Type the name of the element you are looking or select the type of that element.
The “Work Space” is the main part of the Tool and it is where all the dialogs are displayed. You can open several elements at once. They will be opened in tabs. Any tab can be moved to a new window and be moved back to the main window.
