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 cross-platform file-system access
NFS client products
HCL supports several NFS client products that provide Windows® computers with access to VOBs and dynamic views on Linux® or the UNIX® system.
Setting the correct logon name
To avoid VOB and view access permission problems, you must configure the NFS client to log on using user and group names on Linux® and the UNIX® system that match your Windows® user and primary group names.

- 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
    - NFS client products
      HCL supports several NFS client products that provide Windows® computers with access to VOBs and dynamic views on Linux® or the UNIX® system.
      - Disabling automatic case conversion
        Some NFS client products change the capitalization of file names by default, typically by converting to lowercase. This behavior can cause problems for the MVFS and cleartool commands so you must disable case conversion in the product you are using.
      - Setting default protection for an NFS client
        If you plan to work in a shared view on a host running Linux® or the UNIX® system, configure your NFS client with a default protection that grants group write access. Without this permission, other developers cannot modify view-private files that you created.
      - Setting the correct logon name
        To avoid VOB and view access permission problems, you must configure the NFS client to log on using user and group names on Linux® and the UNIX® system that match your Windows® user and primary group names.
        Setting the correct logon name in OpenText NFS Client
      - OpenText NFS Client: Disabling MS-DOS sharing
        The OpenText NFS Client MS-DOS sharing option is incompatible with dynamic views.
      - Windows® tags for VOBs on Linux or the UNIX system with remote storage pools
        If a VOB on a host running Linux® or the UNIX system includes remote storage pools, Windows® hosts that use an NFS client product cannot access the VOB unless it has a tag in the Windows region that includes a split pool map, which provides a network path to each of the remote pools.
      - Automounting and NFS client software
        Disable automounting when using any supported NFS client product. This allows the NFS client to use UNC names to access VOB and view storage on Linux or the UNIX system.
    - SMB server products
      HCL supports several SMB server products that make Linux® and UNIX® file systems accessible from Windows® computers.
  - 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.
  - 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.

Setting the correct logon name

To avoid VOB and view access permission problems, you must configure the NFS client to log on using user and group names on Linux® and the UNIX® system that match your Windows® user and primary group names.

About this task

To verify that matching user and group names exist, pass the name of an NFS server host to versionvault-home-dir\etc\utils\credmap. In this example, user NT_WEST\akp who is a member of the domain group clearusers has matching user (akp) and group (clearusers) accounts on the host that is running Linux® or the UNIX® system, saturn:

versionvault-home-dir\etc\utils\credmap saturn
Identity on local system: User: NT_WEST\akp (NT:S-1-3-21-108034363-97353062-1565875335-1402) Primary group: NT_WEST\clearusers (NT:S-1-3-21-108034363-981762062-1565875335-1044) . . . Identity on host "saturn": User SID: LINUX:UID-2270 Primary group SID: LINUX:GID-88 . . .

If the user or group ID returned by credmap has a negative value, the target host running Linux® or the UNIX® system cannot find a matching user or group name on Linux® or the UNIX® system for the Windows® user who is currently logged on. For more information, see Common user and group names.
