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.
This administrative guide is designed for experienced
system administrators with knowledge of scripting and command-line conventions, file-system access
controls, networking protocols, and system administration tools for computers that run Linux, the
UNIX system, or Windows operating systems.
- 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. DevOps Code ClearCase can use IBM Common Licensing, which is based on the FLEXlm license management tool from GLOBEtrotter Software, Inc., or ClearCase Licensing, a proprietary licensing scheme. - 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. - Administering the CCRC WAN server
- About CCRC WAN server parallel view loading
- Administering and using CMI task-provider integrations
DevOps Code ClearCase supports integrations with task providers such as Rational® ClearQuest®, Rational Team Concert (RTC), and Atlassian Jira through the Change Management Interface (CMI).
