BA Training Module 5.2 | Rational ClearCase v Rational ClearCase  What is a VOB? Versioned Object Base the whole database consists of several VOBs  A read-only repository of ClearCase elements  A network-wide, file system resource which stores version-controlled data  A user accessible repository that resides:  on a Windows NT system, or  on a UNIX system

BA Training Module 5.2 | Rational ClearCase v Rational ClearCase  Basic Actions for an Element  Checkout - a new editable version is created - only one person can edit the file at the same time  Checkin - the version that was created by checkout command is saved to the VOB and is then visible to the other views - the element changes to write-protected mode  Undocheckout - undo operation for checkout  These Options can be selected when right clicked on the application.  Rational ClearCase  Workspace Management - Views  Dynamic Views  Snapshot Views

BA Training Module 5.2 | Rational ClearCase v Other Options

BA Training Module 5.2 | Rational ClearCase v Rational ClearCase  WHAT IS A VIEW?  Workspace for an individual developer or closely coordinated group.  Selects versions of Versioned Object Base (VOB) directories and files.  Allows developers to work without interfering with others.  File checkout by particular user is reserved fro him to modify.No other user can access that folder for modification unless its modified and checked in.

BA Training Module 5.2 | Rational ClearCase v Rational ClearCase  Version Selection by Views  A view selects versions of elements  What is seen is the result of an ordered  Set of rules called a configuration specification  Selected versions appear in a standard  Directory tree with recognizable file names. Eg:R0234/Business/System Checkout d1046/Development/System Design

BA Training Module 5.2 | Rational ClearCase v Rational ClearCase  What is a Configuration Specification? Each view has a config spec that defines a set of rules for selecting versions of file and directory elements  A default config spec is automatically set whenever you create a new view The default config spec selects files or directories that are:  checked out, or  the latest version on the main branch of the version tree  The Default Config Spec:  element * CHECKEDOUT  element * \main\LATEST Update View gives latest config spec.

BA Training Module 5.2 | Rational ClearCase v Update View

BA Training Module 5.2 | Rational ClearCase v Rational ClearCase  When To Use Snapshot Views  You want to work with source files that are under ClearCase control while disconnected from network  You prefer to use a view that is updated only at your request  You want to access a view from a machine that is not a ClearCase host

BA Training Module 5.2 | Rational ClearCase v Rational ClearCase  Dynamic Views  Transparent access to elements - access to virtually any version of any element. -Always up-to-date  Minimal copying  Provides build auditing – Whenever new build done by CM group.

BA Training Module 5.2 | Rational ClearCase v Rational ClearCase  Snapshot View vs. Dynamic View Similar  Use config specs rules to select element versions  Follow the checkout, edit, checkin paradigm  Allow reserved or unreserved checkouts

BA Training Module 5.2 | Rational ClearCase v Rational ClearCase  As development progress, a snapshot view becomes out of date and must be explicitly updated  A checkout of an element may use the version loaded into the view, not necessarily the latest version in the VOB  To check in such an element, you may have to perform a merge  If the element version is not the latest version, you are asked to confirm which version to checkout
