Oracle warehouse builder client tools




















The Runtime Platform Service is invoked through a database job that is automatically started when the database is started and shut down when the database is shut down. The Design Repository, installed in an Oracle database, stores the metadata definitions for all of the objects used in Warehouse Builder. This is where all of the design information is stored for the target systems you are creating. You can access metadata stored here using the client user-interface, or through OMB Plus, the Warehouse Builder scripting utility.

The runtime repository, installed in an Oracle database, stores all of the deployment data as well as data from executed mappings and process flows. This is where the target environment information is stored for the business intelligence systems you create.

This includes connection information for all of the deployment locations. This reporting browser enables you to view your deployment and execution audit information from a web-based application. The reports are based on data stored in the Runtime Repository.

This reporting browser enables you to view your metadata stored in the design repository from a web-based application and provides information to larger audiences. The information is organized into a format targeted for business-oriented users. The reports are based on data stored in the Warehouse Builder Design Repository. Warehouse Builder contains a catalog of objects known as First Class Objects. These include objects that can be imported, designed, and deployed. First Class Objects include the set of objects that can be run through Warehouse Builder services.

Figure shows the First Class Objects along the top of the diagram and the available Warehouse Builder services on the bottom. When you design targets in Warehouse Builder, you have a wide variety of deployment targets from which to choose. Depending on your business intelligence needs you can decide how you want to deploy your design.

You can use Warehouse Builder to deploy to any of the following systems:. Warehouse Builder offers the following benefits for data integration and business intelligence system deployment:. Rapid Design: Warehouse Builder reduces the design time by providing easy to use visual editors, wizard-driven user interfaces, and a library of predefined transformations.

Centralized Design: All information about the design of the system is stored and managed in one central place, the Warehouse Builder design repository. This is a single source of the entire design and eliminates the extra cost of inconsistencies caused by reducing duplication of metadata. Reduce Time to Incorporate Changes: Advanced Life Cycle management features based on the single repository enable a smooth maintenance process.

Error-Free Code: Because it is generated from a design stored in one place, the code is not only error-free, but also easy to re-create, upgrade, and maintain. Leverage Technology Investments: By using the Oracle database as both a transformation engine and storage facility, Warehouse Builder leverages Oracle scalability, performance, security and high availability. Oracle warehouse builder is an ETL extract, transform, load tool created by Oracle corporation which offers graphical environment create and build data integration processes which are actually a data preprocessing technique that is used to combine data from multiple sources into a unified view combining multiple heterogeneous data sources into a coherent source for the users which allow the data integration from multiple data sources like files and multiple databases to get some valuable as well as meaningful insights from data for further analysis.

The major feature areas of oracle warehouse builder consist of data modeling, data profiling, data quality, ETL extraction, transformation, load , advanced data lineage, metadata management, business-level integration of ERP application data, impact analysis and integration with business intelligence tools for reporting purposes.

The oracle warehouse builder client application provides a GUI graphical user interface , which allows a user to define, design and implement business intelligence systems. It makes working easy. The deployment manager and code generator are the components of the client application. They help in the creation and management of the system created by the user.

This component is responsible for managing all the aspects related to deployed objects and deployment. It allows the user to select the objects to be deployed and the manner the user wants those objects to be deployed.

After deployment of the objects, these objects can be executed. The code generator enhances the optimal performance of the Oracle database systems. The server-side component of the warehouse builder is the runtime platform service. You do not move data or metadata until subsequent steps.

In the Connections Navigator, establish these connections by defining locations. Expand the Location node and the nodes within it to gain a general understanding of the types of source and targets you can access from Oracle Warehouse Builder. For more information about locations see "Locations Navigator".

Identify the target schema. Although you can use a flat file as a target, the most common and recommended scenario is to use the Oracle Database as the target schema.

To define the target schema, begin by creating a module. Modules are grouping mechanisms in the Projects Navigator that correspond to locations in the Connections Navigator. The Oracle target module is the first of several modules you create in Oracle Warehouse Builder.

In the Projects Navigator, expand the Databases node. Right-click Oracle and select New. The Create Module Wizard appears. Set the module type to Warehouse Target and specify whether the module is be used in development, quality assurance, or production. This module status is purely descriptive and has no bearing on subsequent steps you take.

When you complete the wizard, the target module displays with nodes for mappings, transformations, tables, cubes and the various other types of objects you use to design the target warehouse. At your discretion, you can either create another Oracle module to contain Oracle source data or proceed to the next step. Under the Connections Navigator, notice the Control Centers node. If you choose to use the default execution environment, continue to the next step.

Alternatively, you can define new control centers at any time. Thus far, these instructions describe the creation of a single project corresponding to a single execution environment.

You can, however, reuse the logical design of this project in different physical environments such as testing or production environments.

Deploy a single data system to several different host systems or to various environments, by creating additional configurations. Adjust the client preference settings as desired or accept the default preference settings and proceed to the next step.

From the main menu in the Design Center, select Tools and then Preferences. As a new user, you may be interested in setting the "Environment Preferences" and the naming mode under "Naming Preferences".

For example, the following entry in Oracle Warehouse Builder. In this section, you create modules for each type of design object into which you intend to import metadata. Then create a module for each relevant location by right-clicking on the node and select New. Import metadata from the various data sources: right-click the module and select Import to extract metadata from the associated location. Oracle Warehouse Builder displays a wizard to guide you through the process of importing data.

Data can only be transformed into actionable information when you are confident of its reliability. Before you load data into your target system, you must first understand the structure and the meaning of your data, and then assess the quality. Consider using the Data Profiling Option to better understand the quality of your source data. With the Data Profiling Option, you can correct the source data and establish a means to detect and correct errors that may arise in the loading of transformed data.

In this section, you create and design the data objects for the Oracle target module. In previous steps, you may have imported existing target objects. To create data objects, you can either start the appropriate wizard or use the Data Object Editor. To use a wizard, right-click the node for the desired object and select New. After using a wizard, you may want to modify the object in the editor.

In that case, right-click the object and select Open Editor. You can validate objects as you create them, or validate a group of objects. In the Projects Navigator, select one or more objects or modules, then click the Validate icon. Examine the messages in the Validation Results window. Correct any errors and try validating again.

To redisplay the most recent validation results at a later time, select Validation Messages from the View menu. To configure a data object, select the data object in the Projects Navigator and click the Configure icon. Or right-click the data object in the Projects Navigator and select Configure. Configuring data objects specifies the physical properties of the object. You must not generate and deploy data objects without specifying the physical property values.

When you create data objects, Oracle Warehouse Builder assigns default configuration property values based on the type of object. In most cases, these default values are appropriate. You can edit and modify the configuration property values of objects according to your requirement. For example, you configure a table to specify the name of the tablespace in which it is created.

In the Projects Navigator, select one or more objects or modules, then click the Generate icon. Examine the messages in the Generation Results window. To redisplay the most recent generation results at a later time, select Generated Scripts from the View menu. Alternatively, in the Data Object Editor, you can generate code for a single object by clicking the Generate icon. If your computer supports the autorun feature, then the autorun window automatically starts Oracle Warehouse Builder installation.

If your computer does not support the autorun feature, locate the executable setup. Start the installer by starting the setup. If you select local node, then you must install Oracle Warehouse Builder separately for each system unless installing to a shared disk.

When prompted, specify a home directory to be used only for Oracle Warehouse Builder installation. Be sure you are not logged in as the root user when you start Oracle Universal Installer. If you log in as root user when you start Oracle Universal Installer, then only the root user has permissions to manage Oracle Warehouse Builder.

As the installation proceeds, the Oracle Universal Installer prompts you to run several scripts. You must switch users and run the script as root. When the software installation completes successfully, you can continue with the next step in "Installing Oracle Warehouse Builder". The resulting service name is instn. For example, if the instance name is abcdef1 , then the service name could be abcdef1.

For a given instance, instn, verify the service is running with the following command:. An Oracle Universal Installer silent installation runs in the background and does not require input from the user. Instead of prompting the user to select a series of installation options, the software uses a pre-defined set of options stored in a response file or passed on the command line.

A response file specifies the information normally provided by the user to Oracle Universal Installer interface during an interactive installation session.

Each answer is stored as a value for a variable identified in the response file. For example, values for Oracle home or install type can be set automatically within the response file. Open a Command window and navigate to the directory containing the response file that is used for the silent installation.

Use the following command to start the silent installation:.
