- 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.
      - 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.

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.

About this task

In addition to identifying and correcting internal inconsistencies in a VOB, checkvob can identify and correct these problems:

VOBs with multiple AdminVOB hyperlinks
Global types with local copies whose names do not match
Eclipsing types
Eclipsing locks on local copies of global types
Mismatched protections between global types and their local copies

To find and, optionally, fix the global types problems in the hierarchy, use the following procedure.

Procedure

Run checkvob –global in any VOB in the hierarchy.
If checkvob detects that the VOB has more than one AdminVOB hyperlink, it stops and prompts you to correct the problem.
To correct the problem, use cleartool describe –long to list VOB hyperlinks, and then use rmhlink to remove all but one of them.
In this example, the VOB \sources has two AdminVOB hyperlinks, one of which must be removed before checkvob can continue checking the hierarchy.
cleartool describe –long vob:\sources
versioned object base "\sources" ... Hyperlinks: AdminVOB@2@\sources -> vob:\projects AdminVOB@3@\sources -> vob:\admin1cleartool rmhlink AdminVOB@3@\sources
Removed hyperlink "AdminVOB@3@\sources".
After the hierarchy has been corrected, run checkvob –global again to check for problems with global types in the hierarchy.
checkvob can detect the following types of problems:
- Eclipsing local types
- Eclipsing local locks
- Protection mismatches
- Name mismatches
Review the log file, and then run checkvob –global –fix to correct any problems.
With the –fix option, checkvob does the following:
- Changes the name of each local copy to match the name of its global type.
- Attempts to acquire eclipsing local copies and eclipsing ordinary types. If a type being acquired is locked, the locks are discarded the global type is locked. If the global type is not locked, the lock information from the first acquired type is applied to the global type.
- Changes ownership of each local copy to match the ownership of its global type.
Unless you specify –force, checkvob prompts you before attempting to fix any problems it detects.
