VMS Help SCA, SCA Topics, Libraries, Project Libraries  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    There are many ways you can organize the SCA libraries for your
    project. Usually, there is one library (or set of libraries)
    for the whole project. Each developer has a personal library
    containing modules that they have changed but have not yet made
    available to the entire project. However, if there is only one
    developer working on the project, it makes more sense to use a
    single SCA library.

    There are many ways you can organize your project libraries. You
    can have one project SCA library if it is a reasonable size. You
    can use several libraries, one for each subsystem. You may want to
    organize your SCA libraries the way your development environment
    is organized. For example, have one SCA library for each CMS
    library. If your project is divided into different subsystems,
    you may want one SCA library for each subsystem.

    For information on creating your own SCA library, see the help
    topic Building_An_SCA_Library.

    Examples of Typical Libraries

    Consider a project with three developers: Paul, Mark, and Joanna.
    The project consists of five different subsystems. Each subsystem
    has its own SCA library in the following directories:

       DISK1:[PROJECT.SUBSYSTEM1.SCA]
       DISK1:[PROJECT.SUBSYSTEM2.SCA]
       DISK1:[PROJECT.SUBSYSTEM3.SCA]
       DISK2:[PROJECT.SUBSYSTEM4.SCA]
       DISK2:[PROJECT.SUBSYSTEM5.SCA]

    Each of the developers also has a personal SCA library as follows:

       DISK1:[PAUL.SCA]
       DISK2:[MARK.SCA]
       DISK1:[JOANNA.SCA]

    Paul uses the following command to set up his SCA libraries:

      LSE Command> SET LIBRARY disk1:[paul.sca], -
      _LSE Command> disk1:[project.subsystem1.sca], -
      _LSE Command> disk1:[project.subsystem2.sca], -
      _LSE Command> disk1:[project.subsystem3.sca], -
      _LSE Command> disk2:[project.subsystem4.sca], -
      _LSE Command> disk2:[project.subsystem5.sca]

    Mark and Joanna use the same command, but the first library in the
    list is their own SCA library.

    When Paul changes a module in Subsystem 1, he compiles it
    and loads it into his personal library in DISK1:[PAUL.SCA].
    For Paul, this hides the old version of the module in
    DISK1:[PROJECT.SUBSYSTEM1.SCA], so his SCA library is up to date
    and consistent with his changes.

    Mark and Joanna do not see Paul's changes in their SCA libraries
    because they are not using the SCA library (DISK1:[PAUL.SCA])
    that Paul updated. They still see the old version of the module in
    DISK1:[PROJECT.SUBSYSTEM1.SCA].

    Once Paul has completed his change, the nightly build
    updates everything for Subsystem 1, replacing the module in
    DISK1:[PROJECT.SUBSYSTEM1.SCA]. Now Mark and Joanna can both see
    the change.
