class="mw-redirect" title="Computer software">computer software</a> tools that supports <a href="/wiki/Software_configuration_management" title="Software configuration management">software configuration management</a> (SCM) of <a href="/wiki/Source_code" title="Source code">source code</a> and other <a href="/wiki/Software_development" title="Software development">software development</a> assets. It also supports design-data management of electronic design artifacts, thus enabling hardware and software co-development. ClearCase includes <a href="/wiki/Revision_control" class="mw-redirect" title="Revision control">revision control</a> and forms the basis for configuration management at large and medium-sized businesses, accommodating projects with hundreds or thousands of developers. It is developed by <a href="/wiki/IBM" title="IBM">IBM</a>. </p><p>ClearCase supports two configuration management models: UCM (Unified Change Management) and base ClearCase. UCM provides an out-of-the-box model while base ClearCase provides a basic infrastructure (UCM is built on base ClearCase). Both can be customized to support a wide variety of needs. </p><p>ClearCase can accommodate large binary files, a large number of files, and large repository sizes. It supports branching and labeling. It enables the correct merging of refactored files by versioning directories.

Beginning with version 7, the server platform runs Websphere Application Server with a server application called the Change Management Server (CM Server), which served ClearCase clients via the HTTP Protocol. (Before version 7 there was a web service by which users could access ClearCase via their browsers.) CM server has since been replaced by the ClearCase Remote Client Wide-Area Network Server (CCRC WAN server), which continues to be based on Websphere Application Server. </p> <div class="mw-heading mw-heading2"><h2 id="Views">Views</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=IBM_DevOps_Code_ClearCase&action=edit&section=3" title="Edit section: Views"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>A distinguishing feature of ClearCase is the <a href="/wiki/MultiVersion_File_System" class="mw-redirect" title="MultiVersion File System">MultiVersion File System</a> (MVFS), a proprietary <a href="/wiki/Networked_filesystem" class="mw-redirect" title="Networked filesystem">networked filesystem</a> which can mount VOBs as a virtual file system through a dynamic view, selecting a consistent set of versions and enabling the production of <a href="/wiki/Derived_Object" class="mw-redirect" title="Derived Object">derived objects</a>. This was a departure from the repository-and-sandbox model because it enabled the early management of artifacts (that is, before they are checked in) and was not limited to the management of these first-order configuration items. </p><p>ClearCase also supports snapshot views, which are copies of repository data. As opposed to dynamic views, snapshot views are maintained on a local (OS-specific) file system and do not require network access. Instead, a snapshot view stores a copy of the VOB data locally on the user's computer. Snapshot views can be used while disconnected from the network and later synchronized with the VOB when a connection is reestablished. This mode of operation is similar to that of CVS (Concurrent Versions System) software. </p><p>The dynamic and snapshot view types are supported by the ClearCase local client (CCLC). The ClearCase remote client (CCRC) supports analogous view types: the automatic view and the web view. Both are copy-based, but the automatic view uses the MVFS to support local, shareable pools of VOB objects. </p><p>From the perspective of the client computer, a ClearCase view appears to be just another file system. New files and directories created in a ClearCase view are referred as "view-private" to indicate that they are specific to the view and not version-controlled. This feature allows build systems to operate on the same file system structure as the source code and ensures that each developer can build independently of one other. At any time, a view-private object can be added to source control and become a versioned object, rendering it visible to other users. </p><p>Developers typically have one or more views at their disposal. It is sometimes practical to share views between developers, but sharing branches is the more common practice. A branch hierarchy is often useful: an entire development project can share a common development branch, while a smaller team can share a sub-branch, with each developer having his or her own private branch. Whenever a change on a branch is deemed stable enough, it can be merged to the parent branch. </p> <div class="mw-heading mw-heading2"><h2 id="The_configuration_specification">The configuration specification</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=IBM_DevOps_Code_ClearCase&action=edit&section=4" title="Edit section: The configuration specification"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Under base ClearCase, each view is controlled by its associated <i>configuration specification</i>, commonly referred to as a <i>config spec</i>. This is a <a href="/wiki/Domain-specific_programming_language" class="mw-redirect" title="Domain-specific programming language">collection of rules</a> (stored internally in a text file, but compiled before use) that specifies what element versions (files or directories) are to be displayed in a view. To determine which version, if any, of an element should be visible, ClearCase traverses the configuration specification line-by-line from top to bottom, stopping when a match is found and ignoring any subsequent rules. A configuration specification can also reference other configuration specifications by means of an 'include' statement. </p><p>In the UCM management model, config specs do not need to be created or maintained manually: they are generated and maintained by ClearCase UCM operations. </p> <div class="mw-heading mw-heading2"><h2 id="Builds">Builds</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=IBM_DevOps_Code_ClearCase&action=edit&section=5" title="Edit section: Builds"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The <a href="/wiki/Networked_filesystem" class="mw-redirect" title="Networked filesystem">networked filesystem</a> provided by MVFS allows for build auditing. Builds in views that use the MVFS can monitor and record file <a href="/wiki/I/O" class="mw-redirect" title="I/O">I/O</a> operations performed during the build process and associate each such event with the command that triggered it. This allows ClearCase to produce a <a href="/wiki/Bill_of_materials" title="Bill of materials">bill-of-materials</a> which it calls a Configuration Record (CR) for all builds and enable <a href="/wiki/Traceability" title="Traceability">traceability</a> for either <a href="/wiki/Software_configuration_management" title="Software configuration management">software configuration management</a> purposes or as part of a larger <a href="/wiki/Application_lifecycle_management" title="Application lifecycle management">application lifecycle management</a> process. Build auditing is performed with command-line tools such as a built-in make tools (omake, clearmake) or by using the clearaudit command, which can invoke another build tool, such as Unix make (1). </p><p>The Versioned Object Base (VOB) that stores versions of file elements and directory elements also stores derived objects and metadata associated with these object types. </p><p>The bill-of-materials artifact produced as the result of build auditing is known as the <i>Configuration Record</i>. It contains: </p> <ul><li>The build procedure: The method (script, makefile, and so on) that invoked the build.</li> <li>Inputs: All files (and their specific versions) that were used for a particular build.</li> <li>Outputs: All <a href="/wiki/Derived_object" title="Derived object">derived object</a> (DO) files (and any dependent DOs) produced as a result of the build.</li></ul> <p>The dependency information is stored in a configuration record that can be shown for each derived object. The configuration record can be used to create another view that shows all files that have been previously read during the build time. The configuration record can also be used to apply a label to the files (and versions) that were read during the build. </p><p>The MVFS allows derived objects that were built in one dynamic view to be automatically "copied" to another dynamic view that requires "exactly the same" derived object. Two derived objects are deemed to be "exactly same" if they have the same <i>configuration record</i> (that is, <i>bill of materials</i>). The shareable derived objects are physically present in the VOB server, not in the views that reference them. This feature is called <i>winking in</i> derived objects and requires that the clearmake or omake tool is used for builds. </p><p>ClearCase dynamic views are slower than local filesystems, even with a good network infrastructure. Repeated subsequent builds may run faster, due to build avoidance that is enabled by ClearCase's <a href="/wiki/Make_(software)" title="Make (software)">make</a> substitute. Because MVFS requires server access every time a file is accessed, the performance of the file system depends on server capacity. </p> <div class="mw-heading mw-heading2"><h2 id="Client_types">Client types</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=IBM_DevOps_Code_ClearCase&action=edit&section=6" title="Edit section: Client types"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Originally, ClearCase supported only full ("fat") clients running native on Unix and Windows.

The Apollo Domain file system allowed special handler programs to intervene during file access. DSEE made use of this feature to invisibly substitute a versioned copy when a particular file was opened.<sup id="cite_ref-14" class="reference"><a href="#cite_note-14"><span class="cite-bracket">[</span>14<span class="cite-bracket">]</span></a></sup> With the versioning specification resident in the user environment, all accesses to versioned files were redirected, including such mundane accesses as printing, viewing in a generic text editor etc. </p><p>DSEE relied heavily on a file that described all the software modules and their dependencies. The file had to be generated manually, which was a major impediment to its use in large systems. However, once generated, it enabled DSEE to calculate the optimum way to perform a build, re-using all modules that had previously been processed and whose version specifications matched the specifications for the build. </p><p>DSEE also introduced the "version spec," which was called a "thread." This was a list of possible versions that could be in the user environment or in a build. A major innovation was the use of build signatures and software release signatures in the thread. The items in a thread might thus be: </p> <ul><li>Any copies reserved for editing (i.e. checked out)</li> <li>The latest version (usually for developers only)</li> <li>A branched version of a file (a version on an alternate line of development).</li> <li>A labeled version (for developers working on a particular revision level)</li> <li>The version used in build XYZ.</li> <li>The version used in software release x.y.z.</li></ul> <p>Threads were processed from top to bottom for each file. A developer thread might have "reserved" at the top, followed by a labeled version. For a fix to an existing release, the thread would be "reserved", then the release signature. </p><p>In the absence of the invisible file redirection of the Apollo Domain file system, ClearCase uses the virtual file system provided by the <a href="/wiki/MultiVersion_File_System" class="mw-redirect" title="MultiVersion File System">MVFS</a> feature that is described below. The "thread" concept corresponds to the <i>dynamic view</i>.
