4.2 Default View Types

When developers join a project, they use the Join Project Wizard to create their development views, integration views, and development streams. They use a development view and a development stream to work in isolation from the project team. They use an integration view to build and test their work against the latest work delivered to the integration stream or feature-specific development stream by other developers.

Rational ClearCase provides two kinds of views: dynamic and snapshot. Specify which type of view to use as the default for development and integration views. When developers join the project, they may choose to accept or reject the default view types. The Join Project Wizard uses the default values the first time that a developer creates views for a project. Thereafter, the wizard uses the developer's most recent selections as the default view types.

PRODUCT NOTE: Rational ClearCase LT supports only snapshot views.

Dynamic views use the ClearCase multiversion file system (MVFS) to provide immediate, transparent access to files and directories stored in VOBs. ClearCase maps a dynamic view to a drive letter in Windows Explorer. Snapshot views copy files and directories from VOBs to a directory on your computer.

We recommend that you use dynamic views as the default view type for integration views. Dynamic views ensure that when developers deliver work to the integration stream or feature-specific development stream, they build and test their work against the latest work that other developers have delivered since the last baseline was created. Snapshot views require developers to copy the latest delivered files and directories to their computer (a snapshot view update operation), which they may forget to do.
