\title Using ClearCase
IBM Rational ClearCase is a version control, workspace management, parallel
development support, and build automation solution developed by IBM. The
ClearCase client plugin is available on Linux and Windows for accessing a
ClearCase server.
\section1 Using GNU Diffutils with ClearCase
You can use the GNU Diffutils tool With ClearCase to compare files and
activities:
\list 1
\li Download \l{http://gnuwin32.sourceforge.net/packages/diffutils.htm}
{Diffutils} and extract it to a directory in your PATH.
\li Select \uicontrol Tools > \uicontrol Options >
\uicontrol {Version Control} > \uicontrol ClearCase.
\li Select the \uicontrol External radio button. The radio button is
disabled if \c diff is not found in the PATH.
\li In the \uicontrol Arguments field, specify arguments for running
\c diff.
\endlist
\section1 Checking out and Checking in
In addition to the standard version control system functions described in
\l {Using Common Functions}, you can check out and check in files.
To create a writable copy of a file, select \uicontrol Tools >
\uicontrol ClearCase > \uicontrol {Check Out}. If you check out files in a
Unified Change Management (UCM) view, they are added to the change set of
a UCM activity. By default, the activities are automatically assigned names.
To disable this functionality, select \uicontrol Tools > \uicontrol Options
> \uicontrol {Version Control} > \uicontrol ClearCase, and then deselect the
\uicontrol {Automatically assign activity names} check box.
To automatically check out files when you edit them, select \uicontrol Tools
> \uicontrol Options > \uicontrol {Version Control} > \uicontrol ClearCase,
and then select the \uicontrol {Automatically check out files on edit}
check box.
To cancel the checkout for a file and delete the checked-out version,
select \uicontrol Tools > \uicontrol ClearCase >
\uicontrol {Undo Check Out}.
To check in checked-out versions of files in the change set of the current
UCM activity, select \uicontrol Tools > \uicontrol ClearCase >
\uicontrol {Check In Activity}.
To create a permanent new version of the current file or all files in the
versioned object base (VOB), select \uicontrol Tools >
\uicontrol {ClearCase} > \uicontrol {Check In}. To be asked to confirm
that you want to check in the files, select \uicontrol Tools >
\uicontrol Options > \uicontrol {Version Control} > \uicontrol ClearCase,
and then select the \uicontrol {Prompt on check-in} check box.
By default, you are asked to enter a comment when checking files out or in.
To suppress this prompt, select \uicontrol Tools > \uicontrol Options >
\uicontrol {Version Control} > \uicontrol ClearCase, and then select the
\uicontrol {Do not prompt for comment during checkout or check-in} check
box.
If you change the read-only attribute of a file that is loaded into a
snapshot view and modify the file without checking it out, you \e hijack the
file. To revert a hijacked file to its checked in version, select
\uicontrol Tools > \uicontrol ClearCase > \uicontrol {Undo Hijack}.
By default, the files in the VOBs are indexed for quick access to their
statuses. To disable indexing, select \uicontrol Tools > \uicontrol Options
> \uicontrol {Version Control} > \uicontrol ClearCase, and then select the
\uicontrol {Disable indexer} check box. To only have some VOBs indexed,
specify them in the \uicontrol {Index only VOBs} field.
