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.
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.
Replicated administrative VOB hierarchies
When you use administrative VOB hierarchies (including those created by UCM) in an HCL VersionVault MultiSite environment, special considerations apply to replication.
Changing mastership of a global type
Mastership is managed separately for global types and their local copies.

- 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.
    - VOB datatypes
      A general understanding of VOB datatypes can place many administrative tasks in context.
    - Administrative VOB hierarchies and global types
      Managing type objects that are used in a group of related VOBs is greatly simplified by creating administrative VOB hierarchies that can share globally defined type objects.
    - Working with global types
      In general, all operations on a global type or a local copy of a global type apply to the global type and all its local copies.
    - Replicated administrative VOB hierarchies
      When you use administrative VOB hierarchies (including those created by UCM) in an HCL VersionVault MultiSite environment, special considerations apply to replication.
      - Global types and mastership
        Restrictions on the creation of global types prevent creation of conflicting types at multiple sites.
      - Changing mastership of a global type
        Mastership is managed separately for global types and their local copies.
  - 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.
  - Administering the VersionVault WAN server
  - 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.
- Administering platforms for HCL VersionVault
  Learn how to perform HCL VersionVault administrative tasks on supported platforms.
- Administering HCL VersionVault MultiSite
  Learn to configure and manage the HCL VersionVault MultiSite environment to support development activities at different locations.

Changing mastership of a global type

Mastership is managed separately for global types and their local copies.

About this task

Changing mastership of a global type does not change the mastership of its local copies. Likewise, changing the mastership of a local copy does not change the mastership of the global type or any other local copies.

For example, the global label type RELEASE-3.0 is mastered by the San Francisco replica in the VOB family \admin_dev, and the local copy in the VOB \dev is mastered by the San Francisco replica in the VOB family \dev:

cleartool describe –fmt "%n\n  %[master]p\n  %[type_scope]p\n" lbtype:RELEASE-3.2@\admin_dev
RELEASE-3.2   SFO@\admin_dev   global
cleartool describe –local –fmt "%n\n  %[master]p\n  %[type_scope]p\n" lbtype:RELEASE-3.2@\dev
RELEASE-3.2   SFO@\dev   local copy

When the mastership of the global type is transferred to the BOS replica, the mastership of the local copy remains the same:

multitool chmaster BOS@\admin_dev lbtype:RELEASE-3.2@\admin_dev
Changed mastership of label type "RELEASE-3.2" to "BOS@\admin_dev"

cleartool describe –fmt "%n\n %[master]p\n %[type_scope]p\n" lbtype:RELEASE-3.2@\admin_dev
RELEASE-3.2 BOS@\admin_dev global

cleartool describe –local –fmt "%n\n %[master]p\n %[type_scope]p\n" lbtype:RELEASE-3.2@\dev
RELEASE-3.2 SFO@\dev local copy

If you enter a chmaster command in a VOB that does not contain a local copy of the specified type, the command fails with the message type not found. For example:

multitool chmaster BOS@\admin lbtype:DOC_SOURCE@\dev
multitool: Error: Label type not found: "DOC_SOURCE".
