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 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.

- 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.
    - Common user and group names
      The identity with which a user logs on to the operating system of an HCL VersionVault host establishes the credentials that determine the users's access rights to artifacts in VOBs and views.
    - Cross-platform file-system access
      Dynamic views must use a network file system to access artifacts such as constructed versions and derived objects in VOB storage directories or files in remote view storage. When the view and VOB are on the same platform, its native network file system is used. When they are on different platforms, cross-platform file-system access is required.

  - 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.
  - 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.

Case-sensitivity

Linux, the UNIX system, and Windows® observe different conventions for case-sensitivity in file name lookup: Linux and the UNIX system are case sensitive; Windows® is not case sensitive. These operating system conventions, which are also typically observed by applications and users, can cause problems when users working in mixed environments share a common set of VOBs and views. There are two aspects of case sensitivity in HCL VersionVault:

Regardless of how you configure HCL VersionVault, all HCL VersionVault applications that refer to pathnames in VOBs, including cleartool and clearmake, are case sensitive.
The multiversion file system (MVFS) on Linux and on the UNIX system is always case sensitive. The MVFS on Windows® can be configured to support various case-sensitivity and case-preservation options.

In general, you can use HCL VersionVault on all supported operating systems with little consideration for case-sensitivity issues. If you encounter unexpected behavior in a mixed environment, read this topic.

General recommendations

To avoid common problems related to differences in case-sensitivity, follow these general recommendations:

In VOBs and views, avoid creating file or directory names that differ only in capitalization of characters. An MVFS that is not case sensitive cannot distinguish such names, and attempts to access such files produce indeterminate results.
Configure the MVFS on Windows® to be not case sensitive. (This is the default setting.)
If you use an NFS client or SMB server product, disable any automatic case-conversion features it may have (See Configuring cross-platform file-system access).

The topics that follow explains pertinent case-sensitivity issues and discuss each recommendation.
