Create sample database

Creating a sample database

When you create a schema repository, you can also create a sample user database. A sample user database is a working user database that provides 40 sample defect records of user information, plus sample queries and reports. Sample user databases can be used to learn how Rational ClearQuest software works and to help train users.
Before you create any Rational ClearQuest database, you must create an empty database container with tools provided by the database vendor.

For information about configuring vendor databases, see the IBM Rational ClearQuest and ClearQuest MultiSite Installation and Upgrade Guide.

To create a sample database:

  1. Start the Maintenance Tool. Then click Schema Repository > Create.
  2. In the Existing Connections pane, enter a name for the schema repository connection in the highlighted item and press Enter.

    By default, the first connection name is 7.0.0. You can rename the connection later.

  3. In the Schema Repository Properties area, select a database vendor and enter the required properties. The properties for each database are different.
    • If you select Microsoft SQL Server, Oracle DBMS, or IBM DB2, enter the physical database name of one of the empty databases that you created with the vendor database tools.

      When you create a DB2 schema repository, the User Name property must be a user identity that has database administrator authority for the DB2 database.

    • If you select Microsoft Access, enter a physical database name; the Maintenance Tool creates a new database with that name.
  4. Click Next.
  5. In the ClearQuest Data Code Page window, select the data code page to use with the new schema repository. You can choose any supported data code page supported by Rational ClearQuest. The default data code page is the one associated with the user-interface language for the operating system on which the Maintenance Tool is running, if that code page is supported. If that code page is not supported, the default data code page is ASCII.
  6. Click Create sample database.

Schema Repository

Creating a schema repository

A schema repository is a database used to store and manage a group of schemas including all versions of those schemas, and their associated user databases.
Before you create a schema repository, you must create an empty database container with tools provided by the database vendor. For information about configuring vendor databases, see the IBM Rational ClearQuest and ClearQuest MultiSite Installation and Upgrade Guide.

To create a schema repository:

  1. Start the Maintenance Tool. Then click Schema Repository > Create.
  2. In the Existing Connections pane, enter a name for the schema repository connection in the highlighted item and press Enter.

    By default, the first connection name is 7.0.0. You can rename the connection later.

  3. In the Schema Repository Properties area, select a database vendor and enter the required properties. The properties for each database are different.
    • If you select Microsoft SQL Server, Oracle DBMS, or IBM DB2, enter the physical database name of one of the empty databases that you created with the vendor database tools.

      When you create a DB2 schema repository, the User Name property must be a user identity that has database administrator authority for the DB2 database.

    • If you select Microsoft Access, enter a physical database name; the Maintenance Tool creates a new database with that name.
  4. Click Next.
  5. In the ClearQuest Data Code Page window, select the data code page to use with the new schema repository. You can choose any supported data code page supported by Rational ClearQuest. The default data code page is the one associated with the user-interface language for the operating system on which the Maintenance Tool is running, if that code page is supported. If that code page is not supported, the default data code page is ASCII.
  6. You have the option of creating a sample user database.
  7. Click Finish.

Shemas and Schema Repository

Schemas and schema repositories

A Rational ClearQuest schema is a complete description of the process model for all the components of a user database. This includes a description of states and actions of the model, the structure of the data that can be stored about the individual component, hook code or scripts that can be used to implement business rules, and the forms and reports used to view and input information about the component. Rational ClearQuest provides out of the box-schemas that can be customized for a client installation.

A schema is a pattern or blueprint for Rational ClearQuest user databases. When you create a user database to hold records, the database follows the blueprint defined in a schema. However, a schema is not a database itself; it does not hold any records about change requests, and it does not change when users add or modify records in the user database.

Rational ClearQuest stores schemas in the schema repository. The schema repository is the master database that contains metadata about the user databases. It does not contain user data.

A schema repository can store multiple schemas, for example, one schema for defect change requests and another schema for feature enhancement change requests. [Source:IBM]

Choose www or no www

URLs with or without www

Introduction

When you write a URL for your website, it can be written with or without "www," like this:

§ http://www.webhostingtalk.com/wiki
§ http://webhostingtalk.com/wiki

Should you include "www" with your URL?

The same and not the same

With most websites, the URLs with and without "www" in them will point to the same site. However, you can specify each URL (with and without "www") to point to a different IP address by modifying your DNS A record.
Some search engines see the above two URLs as two different URLs. Each URL can have a different PageRank, and by using both, you're diluting the PR for each URL.
For PR and SEO purposes, it's preferable to choose one version or the other to use. There are reasons for each choice. Which one you choose depends mostly on personal preference.

Reasons to include www

  • It helps identify a URL as a web address, especially if the domain extension is other than a .com one.
  • Many people will type it in anyway.
  • For some people, URLs look more visually appealing with them.

Reasons not to include www
§ It makes the URL longer, especially if the URL is for a subdomain.
§ It's unnecessary.
§ For some people, URLs look cleaner without them.

How to redirect from one to the other using .htaccess

If your site is on an Apache server, you can choose to have only the version with or without "www" appear. One will direct to the other.

Add one of the following to your .htaccess file after replacing "example.com" with your domain. The "RewriteEngine on" first line activates mod_rewrite.

To redirect to the URL with www
RewriteEngine On
rewriteCond %{HTTP_HOST} ^example.com [NC]
rewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]

To redirect to the URL without www
RewriteEngine on
RewriteCond %{HTTP_HOST} !^$
RewriteCond %{HTTP_HOST} ^www.(.+)$ [NC]
RewriteRule ^/(.*) http://%1/$1 [L,R=301]

IBM Rational Jazz...

Over the years, developing software has been compared to many familiar activities - an art, a science, even a manufacturing process. What all of these comparisons miss is the social dimension: software is best developed by a team of people working together, reacting and responding to each other in order to achieve the best outcome. Jazz is an IBM initiative to help make software delivery teams more effective. Inspired by the artists who transformed musical expression, Jazz is an initiative to transform software delivery making it more collaborative, productive and transparent.

The Jazz initiative is composed of three elements:

  • An architecture for lifecycle integration
  • A portfolio of products designed to put the team first
  • A community of stakeholders

An architecture for lifecycle integration

Jazz products embody an innovative approach to integration based on open, flexible services and Internet architecture. Unlike the monolithic, closed products of the past, Jazz is an open platform designed to support any industry participant who wants to improve the software lifecycle and break down walls between tools.

The Jazz integration architecture is designed to give organizations the flexibility to assemble their ideal software delivery environment, using preferred tools and vendors. More than that, it allows them to do so with the flexibility to evolve their environment as their needs change, to move at their own pace, and not to be hindered by the traditional brittle and restricted integrations associated with traditional tools. The Jazz Integration Architecture defines a common set of Jazz Foundation Services that can be leveraged by any Jazz tool, and explains the rules of the road for accessing and utilizing Jazz services. It also incorporates specifications defined by the Open Services for Lifecycle Collaboration project, an independent, multi-vendor effort to define a set of protocols for sharing information across multiple tools and vendors.

A portfolio of products designed to put the team first

The Jazz portfolio consists of a common platform and a set of tools that enable all of the members of the extended development team to collaborate more easily. This reflects our central insight that the center of software development is neither the individual nor the process, but the collaboration of the team. Our newest Jazz offerings are:

  • Rational Team Concert

    A collaborative work environment for developers, architects and project managers with work item, source control, build management, and iteration planning support. It supports any process and includes agile planning templates for Scrum and the Eclipse Way.

  • Rational Quality Manager

    A web-based test management environment for decision makers and quality professionals. It provides a customizable solution for test planning, workflow control, tracking and reporting capable of quantifying the impact of project decisions on business objectives.

  • Rational Requirements Composer

    A requirements definition solution that includes visual, easy-to-use elicitation and definition capabilities. Requirements Composer enables the capture and refinement of business needs into unambiguous requirements that drive improved quality, speed, and alignment.

A community of stakeholders

Jazz is not only the traditional software development community of practitioners helping practitioners. It is also customers and community influencing the direction of products through direct, early, and continuous conversation. We are doing much of our development on jazz.net, out in the open.

Once you join, you can communicate with the development teams, track the progress of builds and milestones, give us direct feedback on what is working and what is not, and submit and track defect and enhancement requests. You also have full visibility to our detailed plans, status, and progress. At the core of these benefits, you can experience using our product Web interfaces and see us using our products to develop our products. The benefit of this transparency is that it allows you and other customers to become part of a continuous feedback loop that drives development decisions. By providing your feedback early and often, you can understand and influence release direction and priorities before these decisions are locked down.

Objectives

Our goal is to provide a frictionless work environment that helps teams collaborate, innovate, and create great software. To that end, we are focusing on driving fundamental improvements in team collaboration, automation, and reporting across the software lifecycle.

Collaboration

Traditionally, software development has been tooled as if it were a tug-of-war between the productivity of individuals and the automation of processes. Business stakeholders were lucky if they got any consideration at all between major "reviews" and "handoffs". Jazz tools reflect the insight that the center of software development is neither the individual nor the process, but the collaboration within the team. It also recognizes that the team extends beyond the core practitioners to include everybody with a stake in the success of an initiative. A goal of the Jazz initiative is to enable transparency of teams and projects for continuous, context-sensitive collaboration that can:

  • Promote break-through innovation
  • Build team cohesion
  • Leverage talent across and beyond the enterprise

Automation

Our research shows that nearly all organizations want to reduce bureaucratic roadblocks to development by automating tedious and error-prone tasks and burdensome data entry. Yet they also need to maintain or improve process consistency and governance, and increase insight into real project progress. A goal of the Jazz initiative is to automate processes, workflows and tasks so that organizations can adopt more lean development principles at the pace that makes sense for them. The Jazz initiative endeavors to:

  • Improve the support and enforcement of any process, including agile processes
  • Reduce tedious and time-consuming manual tasks
  • Capture information on progress, events, decisions and approvals without additional data entry

Reporting

Getting fast access to fact-based information is essential to any choreographed work effort. But all too often, software development status is gathered through a tedious, manual reporting effort that is out of date by the time it is collected, correlated, and delivered. The Jazz initiative is focused on delivering real-time insight into programs, projects and resource utilization to help teams:

  • Identify and resolve problems earlier in the software lifecycle
  • Get fact-based metrics -- not estimates -- to improve decision making
  • Leverage metrics for continuous individual and team capability improvement

If we already have automation, what's the need for Agents?

“Automation” and “agent” sound similar — but they solve very different classes of problems. Automation = Fixed Instruction → Fixed Outcome ...
