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.
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 registry backup and switchover
HCL VersionVault provides tools that enable you to configure one or more backup registry hosts. A backup registry host can take over when a registry server fails.
Defining a backup registry host
A backup registry host must be configured to back up the registry data of a primary HCL VersionVault registry host.

- 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.
    - Registry data
      An understanding of the registry data model is important for many administrative procedures.
    - The registry server host
      The HCL VersionVault registry is an integral part of most HCL VersionVault operations, so the registry server host must be stable, available, and accessible to all hosts in the network.
    - Guidelines for using multiple HCL VersionVault registries
      You can configure multiple HCL VersionVault registries if you need to limit VOB and view access to specific clients.
    - Assigning an HCL VersionVault host's registry and region
      Use this procedure to assign an HCL VersionVault host to a new registry server, a new registry region, or both.
    - Managing registry data
      Registry data for most common operations is managed automatically. Other operations can require an administrator to create, remove, or modify registry data.
    - Registry administration guidelines
      Ensuring the integrity of registry data is an essential task for any HCL VersionVault administrator.
    - HCL VersionVault registry backup and switchover
      HCL VersionVault provides tools that enable you to configure one or more backup registry hosts. A backup registry host can take over when a registry server fails.

        Defining a computer running Linux or the UNIX system as a backup registry host
        Defining a Windows® computer as a backup registry host
      - Promoting a backup registry host to primary registry host
        Use the rgy_switchover command to promote the backup registry server, and then reconfigure each registry client to use the new server.
      - Restoring the primary registry host
        Restoring a primary registry host requires many of the same steps as configuring and promoting a backup registry host.
      - Moving the registry to a host not configured for registry backups
        If your primary registry host fails and you do not have a backup registry host, you can restore registry data that you have backed up from the primary registry host (using an ordinary file system backup tool) to another host, and then configure that host as a primary registry host.
  - 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.
  - 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 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.

Defining a computer running Linux or the UNIX system as a backup registry host

About this task

Use the following procedure to define a computer running Linux or the UNIX system as a backup registry host.

Log on to the host. You must log on as root to have privileges to stop or start HCL VersionVault, or to create directories and files in the /var partition of most hosts.
Stop HCL VersionVault.
Edit the file /var/adm/hcl/versionvault/config/rgy_hosts.conf. The first line of this file is the name of the host’s registry server. Add a second line that is the host name of the host itself.
Restart HCL VersionVault.

Results

The host becomes a backup registry host and begins running rgy_backup to back up the registry data on the primary registry host specified in the first line of the file /var/adm/hcl/versionvault/config/rgy_hosts.conf.
