Rational Developer for System z, Version 7.6

Library

The purpose of the Library editor is to define and initialize a Library.

The Database Administrator only can update the Library Definition or delete a Library.

Library instances

The library instances are automatically copied in the Design explorer of the Design perspective. As soon as you import entity instances in this view, the information associated with this library are loaded in your workspace. The library entity shows up in the current location on the Pac Library branch of converted entities list. You can also create a new library in the Design explorer of the Design perspective.

Concept

A VA Pac Database is structured in Libraries. Libraries are hierarchically structured on a maximum of nine levels. The hierarchical structure is determined when Libraries are created and can only be modified by the deletion or creation of a Library. The hierarchical level of a library corresponds to the general nature of the information it contains. A specification is described in the user’s connection Library but also in the higher Libraries of which this Library is dependent.

Any modification in a given Library immediately impacts all its dependent Libraries. VA Pac shows the user the elements which belong to the selected Library, as well as those which belong to the higher level Libraries and, optionally, those which belong to the lower Libraries.

The creation of a new Library is a twofold operation:
  • The Database Administrator first creates the Library via a batch procedure (PACS). User input includes the Library code and its parent Library (if any).

  • A Library's characteristics are defined in the Library editor's Definition and -G lines tabs. You open the Library's editor from the Design explorer in the Design perspective.

Library editor

In the Library editor, you indicate the Library's characteristics:
  • the Library name,
  • the default generated language (adapted to the hardware in use) for any instance generated from the Library:
    • Generation language,
    • Cobol type,
    • Map type.
  • the values chosen for the alphanumeric delimiter and decimal presentation character, the comments insertion option and the date presentation:
    • alphanumeric delimiter,
    • decimal point delimiter,
    • comments insertion option,
    • century system date,
    • generated date format,
    • century reference date.
  • comments and generation options.
