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.
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.
About checkvob
VOBs have complex internal and external relationships that can sometimes be disrupted by system or network failures or when a VOB is restored from backup. checkvob is a cleartool subcommand that can find, and in many cases fix, a variety of problems in these relationships.
Using checkvob to find and fix internal VOB inconsistencies
A VOB storage directory contains a VOB database and a number of storage pools. Any operation that modifies VOB data makes changes to the database and at least one pool. When inconsistencies arise between the contents of a VOB database and the contents of its pools, VOB data integrity may be damaged.
Missing and unreferenced data containers
checkvob works to reconcile the contents of VOB storage pools with the information in the VOB database. This reconciliation requires checkvob to categorize data containers based on their relationship to this information.

- 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.
    - The HCL VersionVault scheduler
      The HCL VersionVault scheduler provides a way to automate periodic maintenance on hosts that are configured with support for local VOBs and views.
    - Scrubbing to control VOB storage growth
      Scrubber utilities remove unneeded data from VOB databases. You can control how often they run and what data they remove.
    - About checkvob
      VOBs have complex internal and external relationships that can sometimes be disrupted by system or network failures or when a VOB is restored from backup. checkvob is a cleartool subcommand that can find, and in many cases fix, a variety of problems in these relationships.
      - Replicated VOB considerations
      - Using checkvob to find and fix internal VOB inconsistencies
        A VOB storage directory contains a VOB database and a number of storage pools. Any operation that modifies VOB data makes changes to the database and at least one pool. When inconsistencies arise between the contents of a VOB database and the contents of its pools, VOB data integrity may be damaged.

        Missing and unreferenced data containers
        checkvob works to reconcile the contents of VOB storage pools with the information in the VOB database. This reconciliation requires checkvob to categorize data containers based on their relationship to this information.
        Source pool: missing container
        Source Pool: Unreferenced container (debris)
        DO pool: Missing container
        DO pool: Unreferenced container (debris)
        Minimizing data loss with checkvob -force -fix
        An understanding of the algorithm that checkvob uses the to recover missing data can help you optimize the data recovery process.
      - Using checkvob to find and fix problems with global types
        checkvob can find and often fix many problems that occur in an administrative VOB hierarchy.
      - Using checkvob to find and fix broken hyperlinks
        Careful use of checkvob –hlinks can find and allow you to fix problems with administrative VOB hierarchies.
      - Using checkvob in a UCM environment
        checkvob has a special set of capabilities enabled by the –ucm option that can detect and correct many of the problems that may arise when one or more members of a related set of databases are restored from backup or are otherwise affected by a system or network failure.
    - View storage maintenance for dynamic views
      Encourage users to review, remove, and clean up their own views regularly. In addition, you should periodically remove unneeded shared dynamic views and clean up the private storage areas of those that are still in use.
  - 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.

Source pool: missing container

Description: The VOB database references a source pool data container that does not exist at the expected location.
Causes: Any of the following, depending on whether the database or the pool has the more recent reference time:
- (Database newer) The database records a checkin that is not found in the (older) pool.
- (Pool newer) Pool stores updated, renamed container with new checkin data, but the older database references the old container name, which no longer exists.
- (Pool newer) Pool stores updated container to reflect versions removed with rmver or rmbranch, but the database references old container.
- (Pool or database reference times differ) A chpool operation on a file element in the interval between pool and database reference times leaves the database pointing at wrong pool.
- Unexpected events.
Fix processing: Examine any unreferenced containers. If a container is found that has the correct data (or a subset or superset of the correct data), create a new container and copy in the referenced (subset of) data. If –force is specified or the fix? prompt is accepted, update the VOB database to reference reconstructed containers. Display a list of versions that could not be recovered.
