Creating/Opening a connection

A connection is an access to a VA Pac Database. You must create or open a connection for each new Database you want to access.

To create or open a connection, you need to open the Pacbase Explorer perspective. Then:

There is no limit as to the number of connections.

A wizard guides you through the process of creating/opening a connection
  1. This first step only applies to the creation of a connection. When you create a connection, you must first indicate the bases.ini file to point to. This file, located in the common subdirectory of your VA Pac installation, contains the list of the available Databases you can connect to. Each Database is defined with its own access configuration . For more information about this file, refer to the 'Installation Guide - Server and Client Components', chapter 'Installation of client components', subchapter 'Editing Communication Parameters' at the VA Pac Documentation URL:http://www-1.ibm.com/support/docview.wss?rs=37&uid=swg27005477
  2. When you create or open a connection, you must then enter the information related to your connection: in the Repository Connection page:
    1. Give a name to your connection.
    2. Select, among all the Databases displayed (which come from the bases.ini file), the Database you want to connect to. Its code and location, as defined in the bases.ini file, will then be displayed in the corresponding fields.
    3. If a gateway is to be used, check the corresponding checkbox and enter the hostname and port.
  3. In the Security page, enter the user code and password to connect to the Database you selected in step 2, and the user code and password to connect to the middleware.
  4. Select the Pacbase context, i.e. the session library and view. This context will then be displayed in the bottom part of the workbench.
  5. Click Finish/
Your connection is now active. It looks like this: active connection. If you close it, the icon changes: inactive connection

If you unfold it, you can see folders (represented by afolder icon) which correspond to the VA Pac entities. Each folder contains the instances, if any, which have already been imported from the Database.
