Configuring non-ClearCase access
on Linux or the UNIX system
You can configure a Rational® ClearCase® host
running Linux® or the UNIX® system
to support access to VOBs and dynamic views from computers that do
not run Rational ClearCase.
Note: Non-ClearCase access
is not supported on Rational ClearCase Windows
hosts.
A host running Linux or
the UNIX system on which Rational ClearCase has
not been installed can read VOB data from a VOB server running Linux or
the UNIX system. Typically, the technique is as
follows:
A host running Linux or the UNIX system
and Rational ClearCase must
export a view-extended pathname to the VOB mount point (for example, /view/exportvu/vobs/vegaproj).
Edit the file /etc/exports.mvfs to specify this
pathname.
One or more non-ClearCase hosts
access the VOB through a view-extended pathname. For example, a host
may have an entry in its file-system table that begins
Non-ClearCase access
carries several restrictions:
VOB access. Users on the non-ClearCase host
can read, but cannot modify, data from VOBs on VOB server hosts running Linux or
the UNIX system that have been configured for non-ClearCase access.
They are also restricted to using the element versions selected by
the specified view; they cannot use version-extended or view-extended
pathnames to access other versions of the VOB's elements.
Building. Although users cannot modify VOBs that are accessed
through an export view, they can write to view-private storage. Users
can modify these view-private files with an editor and build them,
though not with clearmake. Files created by such
builds do not become derived objects; they are view-private files,
unless developers take steps to convert them. (For more information,
see IBM Rational ClearCase Guide to Building Software.)
Because clearmake and other build-management
tools do not run on the non-ClearCase host,
configuration lookup and DO sharing are not available.
NFS problems with non-ClearCase access
Depending on the NFS implementation on the non-ClearCase host,
you might encounter various problems when using non-ClearCase access.
