Updating Working Environments

When a developer checks out a file, the checked-out version is locked in the Repository, and a local copy is made in the developer's PWE. When a developer is satisfied with changes he/she has made to a checked-out file (compilable!), he/she checks it back in. This means that the new (checked-in) version replaces the older (checked-out) version in the Repository. However, the SSWE still has the older version of the file, and the objects in the SOWE are also based on this version.
Clearly, the working environments are no longer consistent with each other, and they need to be updated so that all PWEs (i.e., their owners) can access the most current state of the project.
Updates should be done on a regular (daily) basis, especially if you have a large development team. The shared working environments (SSWE and SOWE) should only be updated by the Working Environments Administrator. Although it is relatively natural for individual developers to update their PWEs when they start work, this can also be done by the Working Environments Administrator.
You update your working environments in the following order:

  • First, update the SSWE - the latest information is taken from the Repository.

  • Then, update the SOWE (which accesses the SSWE) and build the targets with the latest file versions. The PWEs access the SOWE, so you can use the up-to-date object code in the SOWE for builds in PWEs.

  • Finally, update your PWE so that you have a view to the latest configuration.

Here, only the most basic update requirements are described. For information on more advanced options and unattended updates, please refer to the User's Guide.
