- Administering DevOps Code ClearCase®
  Learn about performing administrative tasks for a DevOps Code ClearCase® community including managing software licenses, user and group accounts, ClearCase server and client hosts, shared data, and the network that connects them.
  - DevOps Code ClearCase® network planning and administration
  - License servers and license administration
    Most DevOps Code ClearCase® applications and commands (cleartool commands, for example, or GUIs such as the ClearTeam Explorer) require a license to run.
  - Reconfiguring ClearCase® to use a different JRE
    When you change the Java Runtime Environment (JRE) for DevOps Code ClearCase®, you must reconfigure the product to make it work with the new JRE.
  - Administering the DevOps Code ClearCase® registry
    The DevOps Code ClearCase® registry is a central repository of information about shared resources such as VOBs and views.
  - DevOps Code ClearCase® network administration in mixed environments
    A DevOps Code ClearCase® 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 DevOps Code ClearCase® deployment.
  - VOB and view access control
    DevOps Code ClearCase® supports a rich set of access controls on versioned objects.
  - VOB administration
    Because VOBs are the principal repository for artifacts under DevOps Code ClearCase® control, VOB administration is one of the DevOps Code ClearCase 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
    DevOps Code ClearCase® 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 DevOps Code ClearCase® control. Views can also contain view-private file system objects (such as ordinary files and directories) that are not under DevOps Code ClearCase control.
  - Backing up critical DevOps Code ClearCase® data
    Like all databases, VOBs, views, and the DevOps Code ClearCase® registry have special backup and restore requirements.
  - Restoring critical DevOps Code ClearCase® data
    If you have implemented a sound backup strategy for DevOps Code ClearCase® 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 DevOps Code ClearCase® scheduler, which you can use to automate many periodic maintenance chores.
  - Importing data
    DevOps Code ClearCase® 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
  - DevOps Code ClearCase® and Windows domains
  - Configuring non-ClearCase® access on Linux® or the UNIX system
    You can configure a DevOps Code ClearCase® host running Linux® or the UNIX system to support access to VOBs and dynamic views from computers that do not run DevOps Code ClearCase.
  - Configuring DevOps Code ClearCase® 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.

How to disable parallel loading of web views for a single client

About this task

On the client, edit the initialization file for the GUI to set a Java property that disables parallel loading:

Procedure

Locate the .ini file:
1. On ClearTeam Explorer (CTE) GUI, navigate to the RemoteClient subdirectory within the ClearCase® installation directory (the UNIX system and Linux default is /opt/devops/code/clearcase/RemoteClient; the Windows default is C:\Program Files\DevOps\Code\ClearCase\RemoteClient).
2. On the Eclipse shell or other Eclipse-based GUI extended with ClearTeam Explorer plugin, find the .inifile in the same directory as the executable file that runs the GUI.
Open the .ini file for editing:
1. On ClearTeam Explorer (CTE) GUI, the file is ctexplorer.ini
2. On the Eclipse shell or other Eclipse-based GUI extended with the ClearTeam Explorer plugin, the file is eclipse.ini
Edit the .ini file:
1. On ClearTeam Explorer (CTE) GUI, add two lines to the end of the file. As the first line, add -vmargs. As the second line, add -Dcom.ibm.rational.ccrc.disableParallelLoad.
2. On the Eclipse shell or other Eclipse-based GUI extended with ClearTeam Explorer plugin, if there is no -vmargs line in the file, add one at the end, on a line by itself. After the line containing -vmargs, add this line: -Dcom.ibm.rational.ccrc.disableParallelLoad.
Restart the client:
1. On ClearTeam Explorer (CTE) GUI, restart ClearTeam Explorer.
2. On the Eclipse shell or other Eclipse-based GUI extended with ClearTeam Explorer plugin, restart Eclipse.
