HP/ClearCase
Product Brief
A powerful UNIX software engineering toolset for version control,
configuration management, and process control without changing the way
you or your current environment works.HP/ClearCase(TM) is designed for
large-scale and long-lived software development projects. It is
targeted at teams of developers working in a UNIX local area network.
HP/ClearCase manages multiple versions of evolving software, tracks
which versions were used in software builds, performs builds and re-
builds of individual programs or entire releases according to user-
defined version specifications, and enforces project-defined
development policies.
Highlights
o Complete Transparency - any UNIX application or command, without
modification, can transparently access versioned objects in a
repository. A HP/ClearCase repository is implemented as an extensible
part of the UNIX file system so that access to objects in the
repository is through the standard UNIX file system.
o Rule-Based Configurations - developers can easily create development
environments with simple, concise version selection rules to tune the
sharing and isolation of objects. The resulting "view" is created
quickly and with minimum storage overhead.
o Binary Sharing - different configurations share binaries
automatically and correctly, minimizing rebuilds and unnecessary
copies.
o Build Auditing - file system level auditing captures and records
complete configuration information for every build, supporting
complete rebuildability and maintainability.
HP/ClearCase Key Advantages
o HP/ClearCase controls versions of requirements, designs, tests, and
documentation. Every UNIX file system object, including source, text,
binaries, executables, libraries, bitmaps, and the directories that
name these objects, are stored and versioned in a highly reliable
repository.
o HP/ClearCase accurately and automatically records all dependencies,
enabling you to guarantee correct re-builds.
o HP/ClearCase is designed to grow as you grow. The system will work
efficiently for both small development efforts and large projects
involving hundreds of people with millions of lines of code.
o HP/ClearCase was designed with the knowledge that no two
organizations are exactly alike. The system offers a set of powerful
tools for developing customized policy controls and procedures.
o HP/ClearCase manages numerous development configurations
automatically, without copies or links. If twenty engineers are
working on three releases of a software system, they are not working
on three configurations, they are working on 20 or more configurations
that have many versions of sources and binaries in common.
Version Control
o HP/ClearCase maintains a blueprint of the variants of each object
(files and directories). There is no limit on the number, or nesting
level, of branches from the main development line.
o HP/ClearCase stores meta-data for each version and optimizes storage
via delta compression.
o HP/ClearCase contains powerful, n-way graphical compare and merge
capabilities for parallel development.
Build Environment Management
o A developer easily selects the versions of those objects that they
want to work on by applying flexible selection rules - configuration
specifications - to the repository.
o Engineers have a workspace in which they can perform their everyday
tasks - editing, building, debugging - in partial isolation but share
access to data in the actual development tree with other members of
the team.
Configuration Management
o HP/ClearCase builds using makefiles. It monitors file I/O to
accurately and automatically produce a complete record of all system
build dependencies including: objects used and versions selected,
command options used, and tools invoked. There is no need to specify
any dependencies.
o Parallel, distributed builds can be performed using several
processors, either on a single multi-processor host or on multiple
hosts in a network.
Process Control
o Triggers execute user-defined programs or shell scripts prior to, or
in response to, HP/ClearCase events (e.g. checkin.)
o Attributes are user-defined data attachable to any version or
object.
o Hyperlinks connect diverse objects to maintain logical relationships
for requirements tracking.
Who Should Use HP/ClearCase
o UNIX programming teams working on substantial software development
projects who wish to manage this software, over time, as a critical
asset of the business.
o Programmers familiar with make, RCS, SCCS, or DSEE who are looking
for a richer, more capable version control and configuration
management solution.
o Programmers and development teams looking to move to version control
and configuration management for the first time and who need the
solution to work with currently installed tools and methodologies.
o Companies wishing to gain control over the software development
process by implementing defined policies and procedures.
