Figure shows a simple network in which global naming has been achieved. This is not a requirement, but it will facilitate ClearCase administration. MOVED is an actual directory: Please remove this database backup when you are satisfied with the reformat. Vob server casevission path: It is important to personalize and localize the VOB-tag—other users may run the casevisioj on the same host, and you may have occasion to run the tutorial on another host.
Views and Transparent Access. The describe command provides the answer: There are techniques for relaxing these restrictions in practice. List a syntax summary of all cleartool commands, or just on one. Object registry entries are used mostly by ClearCase server processes. It modifies entries in this file to prevent the recursive traversal problem gujde displays a message warning that it cannot perform the modification.
The version tree for hello. Build Auditing and Configuration Records. Verify the new VOB-tags—On a host in the west region: Note that the files are all read-only. The configuration record is moved to the appropriate VOB database, or databases. If possible, keep the tag itself constant over all the regions.

The command fails if anyone else tries to execute it. The standard chmod command can be used on any derived object that appears in a view—shared or unshared. In such organizations, all ClearCase data structures should also belong to the common group—a VOB or view belongs to the principal group of its creator—and will be fully accessible to all users.
In both cases, mvfsstorage simply echoes the directory name. Use command to show differences between files. Go to the VOB root directory to access your files. Reactivate the view—If you renamed the view storage directory in Step 2, restore it to its original name. If a host does not have multiple network interfaces, this file should not exist at all on that host. AssumSte the appropriate user identity—Make sure that you are logged in as user vobadm, in group dvt.
These view-private files can take up a significant amount of disk space. Assigning All Files in a Directory to a New Pool The following example shows how to create a new, remote source storage pool, and then reassign all the current and future elements in a particular directory to the new pool.
The remote storage pool pathname must apply to all hosts that will access the VOB, but the existence of multiple network regions implies that different sets of pathnames are required to access VOBs from different hosts in the network. The View as Isolated Workspace. On a day-to-day basis, you don’t even have to know where a VOB storage directory is located.
This program prompts you to specify the name of a network region. Removing entire elements, using rmelem, is particularly dangerous: If problems occur that cause the conversion script to terminate prematurely, you can simply fix the problem and restart the script.
Several VOBs can be located on the same host; the practical limit is a function both of disk space and of processing resources. User-Level Access to ClearCase Data password database establishes username derek and principal group expermnt.
Clear Case Concepts and Terminology
This casevieion could, in turn, incorporate the contents of an NIS map. Because we are in the target region, the -region argument to mktag is not required.
Request help from ClearCase administrator with a command that does not work. Assign the directory to a separate storage pool—This will enable pinpoint control of scrubbing, which can be invoked on a per-pool basis: Local script that applies a label to a VOB. You might achieve the correct layering by never guode any users to run processes on a host used for an export view, either directly or indirectly—no home directories, and no remote logins except from non-ClearCase hosts.
Any information that you provide will be useful. It’s a community-based project which helps to repair anything.
When an object is locked, it cannot be modified by anyone, even by root, the VOB owner, or the user who created the caseviison. To access ClearCase data, developers must use a view—either implicitly by setting the view or explicitly by using a view-extended pathname. Setting Up ClearCase Views View Storage Requirements Each ClearCase view is implemented as a view storage directory, a directory tree that holds a small database, along with a private storage area that contains view-private files, checked-out versions of elements, and unshared derived objects.
Since each VOB and its export view are located on the same host, three different export views are involved. Casevison client and server programs on all other hosts occasionally communicate with the registry server host, in order to determine the actual storage location of ClearCase data. Each host on which ClearCase is installed is assigned to a particular license server host, and periodically communicates with that host.
Figure shows all of the cleartool commands that affect registry files.
Chapter 1. CASEVision/ClearCase Tutorial: Developing a `Hello World’ Program
View administration is similar to that for VOBs, including registration, backup, periodic maintenance, and access control. But many organizations prefer to have a separate identity for application-specific administration.
Avoid placing too many views on any single machine; avoid placing shared views on VOB hosts but see the next section for an exception. No one else can remove that element. This command marks the VOB database as invalid.
