You must determine the number of schema repositories and
user databases that will make up your Rational® ClearQuest® environment
and the vendor databases and servers that will support your database
set.
All deployments of Rational ClearQuest must
have an administrative host. The administrative host contains the
administrative tools that are used to manage the Rational ClearQuest environment.
All the tools necessary for administering the database set, MultiSite,
users and user groups and other administrative responsibilities are
installed on this computer. The client components can also be installed
for basic ClearQuest functionality
such as creating and working with queries, records, charts, and reports.
The Administrative host must be installed on Windows®.
Some reasons for installing
Rational ClearQuest on Linux® or the UNIX® system are:
- Host the Rational ClearQuest Server
and Web Application which provides access to Rational ClearQuest repositories
through a Web-based interface
- Provide access to the Rational ClearQuest Clients
for users who work solely Linux and UNIX system platforms
- Administer a Rational ClearQuest MultiSite environment
- Integrate with Rational ClearCase®,
both the Base and UCM versions
You can also host the database management systems which house
your schema repositories and user databases on Linux or the UNIX system.
However, you do not need to install
Rational ClearQuest on
these platforms if your only reason for incorporating them into your
environment is to host the database management systems. Schema repositories
and user databases can only be created and administered from a Windows computer which acts
as the administrative host.
Selecting your servers and databases
Rational ClearQuest allows
you to architect your environment in any manor that best suites your
organization's needs as along as all the servers and databases are
supported. You may already know the type of configuration you want
and therefore your next step is simply to verify that you servers
and databases are supported. If you only have a rough idea of how
your environment should look, here are a few implications to consider:
- How geographically distributed is your organization?
- How many users to have and what will be their performance needs?
- Do you plan to deploy a Web environment?
- Do you plan to deploy a MultiSite environment?
