Administering HCL VersionVault
Learn about performing administrative tasks for an HCL VersionVault community including managing software licenses, user and group accounts, VersionVault server and client hosts, shared data, and the network that connects them.
Configuring non-VersionVault access on Linux® or the UNIX system
You can configure an HCL VersionVault host running Linux® or the UNIX system to support access to VOBs and dynamic views from computers that do not run HCL VersionVault.

- Administering HCL VersionVault
  Learn about performing administrative tasks for an HCL VersionVault community including managing software licenses, user and group accounts, VersionVault server and client hosts, shared data, and the network that connects them.
  - HCL VersionVault network planning and administration
  - License servers and license administration
    Most HCL VersionVault applications and commands (cleartool commands, for example, or GUIs such as the VersionVault Explorer) require a license to run.
  - Reconfiguring VersionVault to use a different JRE
    When you change the Java Runtime Environment (JRE) for HCL VersionVault, you must reconfigure the product to make it work with the new JRE.
  - Administering the HCL VersionVault registry
    The HCL VersionVault registry is a central repository of information about shared resources such as VOBs and views.
  - HCL VersionVault network administration in mixed environments
    An HCL VersionVault environment that includes hosts that run Windows and hosts that run the UNIX system or Linux is said to be a mixed environment.
  - Overview of security considerations
    As an administrator, you are responsible for the security of your HCL VersionVault deployment.
  - VOB and view access control
    HCL VersionVault supports a rich set of access controls on versioned objects.
  - VOB administration
    Because VOBs are the principal repository for artifacts under HCL VersionVault control, VOB administration is one of the HCL VersionVault administrator’s most important tasks.
  - VOB datatypes and administrative VOB hierarchies
    There are many types of VOB metadata. Some are unique to a particular VOB, but many must be managed consistently across a group of VOBs that store related artifacts (components of a UCM project, for example). These topics introduce VOB metadata and describe how to use administrative VOB hierarchies to simplify sharing of type objects among related VOBs.
  - Moving VOBs and relocating VOB data
    HCL VersionVault includes tools for moving data and metadata to another VOB and for moving entire VOBs to another disk or host. You may need to use these tools to reorganize VOB directories, redistribute data storage, or rebalance server loads.
  - Views and view administration
    A view provides a workspace where users access versions of file and directory elements that are under HCL VersionVault control. Views can also contain view-private file system objects (such as ordinary files and directories) that are not under HCL VersionVault control.
  - Backing up critical HCL VersionVault data
    Like all databases, VOBs, views, and the HCL VersionVault registry have special backup and restore requirements.
  - Restoring critical HCL VersionVault data
    If you have implemented a sound backup strategy for HCL VersionVault data, it should be easy to restore that data, if necessary.
  - Periodic maintenance
    Periodic attention to storage management and repository integrity is an important administrative function. These topics describe VOB and view storage management tasks, the checkvob utility, and the HCL VersionVault scheduler, which you can use to automate many periodic maintenance chores.
  - Importing data
    HCL VersionVault includes several utilities for importing data from other configuration management systems or directly from the file system itself.
  - Troubleshooting
    These topics cover a variety of procedures that administrators might need to follow to find and fix problems.
  - Improving client host performance
  - Improving VOB host performance
  - Configuring cross-platform file-system access
  - HCL VersionVault and Windows® domains
  - Configuring non-VersionVault access on Linux® or the UNIX system
    You can configure an HCL VersionVault host running Linux® or the UNIX system to support access to VOBs and dynamic views from computers that do not run HCL VersionVault.
    - Setting up an export view for non-VersionVault access
      An export view for non-VersionVault access exports a view-extended pathname to the VOB mount point.
    - Using automount with non-VersionVault access
      Certain considerations apply when creating automount map entries for exported views.
    - NFS problems with non-VersionVault access
      Depending on the NFS implementation on the non-VersionVault host, you might encounter various problems when using non-VersionVault access.
  - Configuring HCL VersionVault for high availability
  - Estimating VOB size
    If you can estimate the number of elements, versions, and derived objects that a VOB will ultimately contain, you can compute a very rough estimate of the size of a VOB that can accommodate them. VOB storage includes a database and pools. On Windows®, the database and pools must reside on a single disk partition. On Linux® or the UNIX system, the pools can be located on a different partition or host, using symbolic links.

  - About VersionVault WAN server parallel view loading
  - Administering and using CMI task-provider integrations
    HCL VersionVault supports integrations with task providers such as HCL Compass through the Change Management Interface (CMI). The integrations require some configuration tasks, after which you can work with UCM activities or base VersionVault branches that are associated with the tasks.

Configuring non-VersionVault access on Linux® or the UNIX system

You can configure an HCL VersionVault host running Linux® or the UNIX system to support access to VOBs and dynamic views from computers that do not run HCL VersionVault.

Note: Non-VersionVault access is not supported on HCL VersionVault Windows hosts.

A host running Linux® or the UNIX system on which HCL VersionVault 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 HCL VersionVault 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-VersionVault hosts access the VOB through a view-extended pathname. For example, a host may have an entry in its file-system table that begins
```
mars:/view/exportvu/vobs/vegaproj /usr/vega nfs ...
```

Restrictions on use

Non-VersionVault access carries several restrictions:

VOB access. Users on the non-VersionVault 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-VersionVault 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 VersionVault Guide to Building Software.)
Because clearmake and other build-management tools do not run on the non-VersionVault host, configuration lookup and DO sharing are not available.
