In fact, it may not even be possible to install it on some hosts—those whose architectures are not yet supported by ClearCase. Choose a view-tag—Select a name that indicates the nature of the work that will be performed in the view.
We consider two cases: Many organizations supplement these local files with network-wide NIS maps, named passwd and group. The -okgmerge option requests that ClearCase attempt automatic merging but requires you to approve each merge before it completes. If any of these requirements is not satisfied, the CHECK doncepts displays a message explaining how to remedy the situation.
If necessary, remove such an entry manually. It also holds the data files data containers for derived objects built in the view.
Use the procedure in the ClearCase Notebook. Ensure self-consistency of the backup—A view cannot be locked with the lock command.
The version is cached as a cleartext data container—an ordinary text file—located in a cleartext storage pool. Created versioned object base “monet. Each VOB is a permanent data repository. ClearCase type managers recreate cleartext data containers automatically, as necessary.
Determine the location of the storage pool—Use the lspool command: You must specify the VOB-tag as a command-line argument.
To change the MVFS cache casevisuon, perform one of the changes described below. Conceptd Access to ClearCase Data Locking Type Objects As an administrator, you will often find it useful to lock type objects; this prevents changes to the instances of those types. Copy the VOB storage directory—First, make sure that the desired parent directory of the target location exists cleaecase is writable.
Installation instructions, release notes, and supplementary technical notes are also provided in the ClearCase. Building on Remote Hosts.
Version labels play an important role in ClearCase. The same VOB can be mounted at several locations on a non-ClearCase host, each mount using a different view. If most developers belong to a single group, make vobadm a cqsevision of that group, too. You may be tempted to let root perform all ClearCase administrative tasks.
For example, this command reports activity over a 5-minute period, with a cumulative sample taken every 60 seconds: Apollo is a registered trademark of Apollo Computer, Inc. Developers think celarcase views and VOBs as being very different: As explained below, storage pools can be remote. Figure illustrates a simple two-region network, each with its own logical set of tag registries.
The VOB stores all the versions of all these files and, as you’ll see in this tutorial, a good deal of other information, too. The standard chmod command can be used on any derived object that appears in a view—shared or unshared.
In this case, the versions are executables, not sources. The effective question is: Resume – Trelco Limited Company. It can also involve even more hosts: Other Helpful ClearCase Documentation Most developers do not seem to like to read manuals, but when they do, they appreciate knowing which ones, or which parts, are the most useful for them.
Wherever possible, select a host that can be accessed with the same hostname by all ClearCase hosts.
This command creates the libpub VOB. This includes the ClearCase release area, the license server, and the registry casevisioh. These server processes run on the host where the VOB storage directory physically resides. If you use a file-oriented backup tool, you need only specify the VOB storage directory to ensure a complete backup. Here are the principal tradeoffs: These pools are caches that accelerate access to elements for clrarcase all versions are stored in a single data container: Vob server access path: A C-language compiler, required for building software during the tutorial, is accessible through your search path.
But if you would prefer a less verbose message, remove the VOB-tag: If you anticipate that a view will need a great deal of private storage, you can use the mkview -ln command to create. Each view-tag entry has a region field, which places the entry in a particular region.
That is, the scrubbers do not reduce the size of any file in the VOB database subdirectory db. Extra memory is especially recommended for users who run memory-intensive applications in the ClearCase environment, make Chapter The db subdirectory must also be on that same host.
All hosts in a given network region use the same tags.
