2 Getting Started with Oracle Ultra Search

This chapter contains the following topics:

Overview

This chapter provides information about getting started with Oracle Ultra Search. A case study is featured that describes installation and use of Oracle Ultra Search. It enables you to create a browser-based search application to query data sources.

The example uses a fictional customer service call center named Ultra Appliance, Inc. Ultra Appliance is a retail company that sells and supports hundreds of different appliances from dozens of manufacturers nationwide. Customers contact the customer service call center every day to receive technical Help for, and assistance with, an appliance.

This chapter describes how the Ultra Appliance search administrator, can set up a browser-based search application that enables call center agents to find information for appliances that they support. It also describes how you, as the Ultra Appliance call center agent, can use Oracle Ultra Search to query the company intranet and database.

Ultra Appliance call center agents must access a variety of online resources to provide the information needed by the customer. In this example, the Ultra Appliance call center agents have access to two types of information:

For this example, the Ultra Appliance call center agents search the company intranet and the problem database for information and any issues associated with, the Springmaster 2000 refrigerator.

Installation

This section gives a vrief overview of installation of of Oracle Ultra Seacrh. The instructions in this section are meant to briefly cover installation. For further installation information, refer to Chapter 4, "Installing Oracle Ultra Search" in this book. For more information refer to the Oracle Universal Installer Concepts Guide for detailed installation instructions. Oracle Ultra Search is installed as part of the Oracle Database Server installation, which uses Oracle Universal Installer.

Using the Oracle Universal Installer

Insert the Oracle Installation Media and start the Oracle Universal Installer. Follow the instructions in the installation wizard to perform an Oracle Database Server installation. For more information, refer to Chapter 4, "Installing Oracle Ultra Search".

Along with the Oracle Database Server, the Oracle Universal Installer also installs the Oracle Ultra Search back end and the Oracle Ultra Search middle tier.

If you have not done this, unlock the Oracle Ultra Search schema and user:

  1. Log in to the database as a DBA user (for example, as SYS).

  2. Unlock the Oracle Ultra Search schema, WKSYS, and set its password:

    ALTER USER wksys account unlock identified by password
    
    
  3. Unlock the Oracle Ultra Search WK_TEST schema. Its password is wk_test.

    ALTER USER wk_test account unlock identified by wk_test
    

Accessing the Oracle Ultra Search Administration Application

You must have an Oracle Ultra Search instance. During installation, an instance is created and you need to configure it by following the directions in "Unlock WK_TEST".

Upon installation, the default Oracle Ultra Search instance, WK_INST, is available, it is built on the default WK_TEST schema.

To access the administration application, start up the Oracle Ultra Search middle tier:

$ORACLE_HOME/bin/searchctl start

After the middle tier has been started, you can access the administration interface with an HTML browser pointed to:

http://your_computer.com:http_port/ultrasearch/admin/index.jsp 

At the end of the installation, find http_port on the Oracle Universal Installer screen. You can find out the value of http_port by looking at:

$ORACLE_HOME/oc4j/j2ee/OC4J_SEARCH/config/http-web-site.xml

Setting up the Query Application

Oracle Ultra Search provides APIs with which you can build customized, J2EE query applications. Oracle Ultra Search also includes an application of this sort.

To set up the query application, do the following steps, using your own set of values for the host name, the port, and the SID:

  1. Add the following entry to the ORACLE_HOME/oc4j/j2ee/OC4J_SEARCH/config/data-sources.xml file:

    <data-source
    class="oracle.jdbc.pool.OracleConnectionCacheImpl"
    name="UltraSearchDS"
    location="jdbc/UltraSearchPooledDS"
    username="wk_test"
    password="wk_test"
    url="jdbc:oracle:thin:@database_host:oracle_port:oracle_sid"
    />
    
    
  2. If you have started the Oracle Ultra Search middle tier to access the Oracle Ultra Search administration application, then you must restart it, with the query application now configured to use the query application:

    $ORACLE_HOME/bin/searchctl stop
    $ORACLE_HOME/bin/searchctl start
    
    

After the middle tier has been started, you can access the query application with an HTML browser pointed to:

http://your_computer.com:http_port/ultrasearch/query/search.jsp.  

At the end of the installation, find http_port on the Oracle Universal Installer screen. You can find out the value of http_port by looking at:

$ORACLE_HOME/oc4j/j2ee/OC4J_SEARCH/config/http-web-site.xml

Setting up the Ultra Appliance Demo

To access the Ultra Appliance intranet site, go to:

http://www.oracle.com/technology/products/ultrasearch/gettingstarted/

To set up the Ultra Appliance company database, perform the following steps:

  1. Copy the appliances.sql script shown in Example 2-1 into a text editor. Save this file as appliances.sql to your database server computer

  2. Upload appliance.sql to your database schema WK_TEST with the following statements:

    prompt > sqlpls WK_TEST/WK_TEST
    SQLPLUS > @appliance.sql;
    SQLPLUS > commit;
    SQLPLUS > exit
    

    Example 2-1 appliances.sql script

    DROP TABLE product;
    CREATE TABLE product (id NUMBER PRIMARY KEY, Description VARCHAR2(200),
