This kind of ClearCase server includes: Introduction to ClearCase Administration v 1. Since each VOB and its export view are located on the same host, three different export views are involved. The larger the block buffer cache, the less frequently it should be flushed.

For a VOB or view with a registered tag, the output from lsvob -long and lsview -long includes: Moving a VOB Same Architecture This section presents a procedure for moving a VOB storage directory to another location, either on the same host or on another host with the same architecture. By contrast, no views are activated automatically at ClearCase startup; the user s on a client host must activate their view s with explicit commands.

You can create or modify this script to set up several at 1 jobs: The scrubber manual page explains how to read this file. Setting Up ClearCase Views 6. Because we are in the target region, the -region argument to mktag is not required. Nothing appears because, in some sense, a VOB contains too much data. The distinction is important for this discussion, because different access-control mechanisms apply: This leaves a redundant copy of the data container in view-private storage.

For example, you can use —rep instead of —replace. A miss simply means that the type manager must be invoked to reconstruct the version again. Consistency is usually achieved by using network-wide databases at the operating system level, such as NIS passwd and group maps.


A VOB or view can have auxiliary data storage on hosts where ClearCase is not installed; such storage is accessed through standard symbolic links. The most common reason is that the VOB host has multiple network interfaces is multihomed —some client hosts might know it as ccsvr01, while others know it as ccsvrgw. Although a VOB appears to be a version-smart file server, its implementation involves significant database access and computation.

Accordingly, a ClearCase-specific mechanism is required to implement the group list of a VOB or view.

Checking for VOB tag registry entry The principal tools for working with storage pools are: In their day-to-day work, developers use VOB-tags and view-tags to access the data structures. See the ClearCase Concepts Manual for an introduction to type objects. There are access-control issues to be addressed if 1 the prospective users of the VOB do not all belong to the same group, and 2 non-group members are to be prohibited from accessing data.

Restart the operating system—Use reboot 1M or any other standard means to restart the operating system. You must specify the VOB-tag as a command-line argument.

concfpts The first time the derived object is winked-in to another view: You can restore a VOB to a new location, on the same host casevisioon on another host.

Go to a directory that affords you some privacy. This enables editing and building—with a native make program or with scripts, not with clearmake.

The extended naming symbol in a version-extended pathname distinguishes the individual version of an element selected by a view from the entire element.


Change to the source directory.

List of Figures

Become the root user. Physically, all tag registries are implemented in a single file. Does the user have permission to access the VOB data? Each host on which ClearCase is installed is assigned to a particular license server host, clearrcase periodically communicates with that host. Changing the source pool of a file moves all its data containers; for a directory element, this changes the source pool to which new elements created within it will be assigned.

If mvfsstorage indicates that a data container is in a non-default VOB storage pool, use the lspool command to determine the location of the pool. In particular, you cannot use the network region facility to handle network idiosyncrasies, such as hosts with multiple network interfaces.

Introduction to ClearCase Administration v – Wood

Then concwpts the directory back in too! This process updates the schema of the embedded VOB database. In some networks, it is not possible to devise global pathnames to all ClearCase storage areas.

The -d option shows the changes in diff 1 format within files that exist in both views. Local script that applies a label to a VOB. Create a new VOB. If necessary, remove such an entry manually. Where is the View? Building on Remote Hosts. For example, on sierra: Most conccepts are used by individuals; it is likely, however, that one or more shared views will be created, requiring some central administration.
