1.3 Choosing EDQ Components and Versions

The following sections show you the components that are required to support EDQ and the supported versions of those components and EDQ.

- Choosing the Correct Combination of EDQ Required Components

- Supported Platforms and Component Versions

1.3.1 Choosing the Correct Combination of EDQ Required Components

EDQ is a Java Web Application that uses a Java Servlet Engine, a Java Web Start graphical user interface, and a data repository within a database. As such, it requires access to the following components:

- a Java Development Kit (JDK)

- a Java Application Server to supply web services. Oracle WebLogic Server and Apache Tomcat are supported.

- a structured query language (SQL) relational database management system (RDBMS) to store configuration data, working data, and the results of work performed by the processes. Oracle Database is supported.

The following application servers and databases are supported for use with EDQ:

- Oracle WebLogic 12.2.1 (from the Fusion Middleware Infrastructure 12.2.1 package), or Apache Tomcat 8.

- Oracle Database 11.2.0.4+ or 12.1.0.1+.

Instructions for installing these components are in Section 2, "Installing the Required External Software Components" See Section 1.3.2 for supported versions of each of these components.

1.3.2 Supported Platforms and Component Versions

Review the list of certified platforms, JDKs, databases, application servers, and releases for EDQ prior to installation. This information is listed in Oracle Enterprise Data Quality Certification Matrix at

http://www.oracle.com/technetwork/middleware/ias/downloads/fusion-certification-100350.html

1.4 Satisfying EDQ System Requirements

This section describes the hardware and software requirements of EDQ. These requirements represent the server configurations that are certified and supported by Oracle for the EDQ product.

1.4.1 Disk and Memory Requirements

Depending on the tasks that EDQ is required to perform, it can place heavy demands on the hardware used to run it. A recommended minimum hardware specification for an EDQ server is:

- 8GB physical memory, with 4GB allocated to the EDQ Java Virtual Machine (JVM)

- At least 4 logical CPUs

- At least 500GB of hard disk space on the database server. The EDQ results schema, which contains the working data that EDQ generates, must have enough space to contain at least 20 times the volume of source data that you expect to process through EDQ. This size may increase if there are many EDQ users working on the same projects at the same time. The configuration schema remains small, normally less than 5GB, unless there is a large amount of user-modified reference data and Case Management data.

Note:
These recommendations do not represent sizing advice for any specific deployment, but rather a starting point for testing size requirements in your environment. It may be appropriate to deploy a larger machine or many machines, depending on the processing load placed on EDQ.

1.4.2 EDQ Directory Requirements

EDQ uses an installation directory and two configuration directories. You should record the location of these directories in case you need to apply manual updates to any of their contents.

EDQ Installation Directory

During the installation process, you must specify an installation directory to contain the EDQ installation files. This directory is known as the EDQ Home (EDQ_HOME) directory and is named as follows:

- If you are installing EDQ as part of the Oracle Fusion Middleware product stack, you must install the EDQ Home directory as a subdirectory of the Oracle Fusion Middleware home (installation) directory. A typical default Fusion Middleware home directory is as follows, depending on the platform:
Linux and UNIX:

/opt/Oracle/Middleware/FMW_HOME

Windows:

C:\Oracle\Middleware\FMW_HOME

Note:
The Middleware home directory is referenced as FMW_HOME in this guide.

- If you use the WebLogic Server or Apache Tomcat application server, you can install the EDQ Home directory in any directory.

The EDQ Home directory requires approximately 1GB of hard disk space.

EDQ Configuration Directories

EDQ requires two configuration directories, which are separate from the EDQ Home (installation) directory that contains the program files. The configuration directories are:

- The base configuration directory: This directory contains default configuration data. Once EDQ is installed, the files in the base configuration directory must not be altered, renamed, or moved.

- The local configuration directory: This directory contains overrides to the default configuration. EDQ looks for overrides in this directory first, before looking in the base configuration directory. Files in the local configuration directory can be modified to customize or extend EDQ.

The names and locations of the configuration directories are as follows:

- If you are using Oracle WebLogic Server, the Configuration Wizard automatically creates and populates the configuration directories in the EDQ domain with the names of oedq.home (base configuration directory) and oedq.local.home (local configuration directory). An example installation path is:

WLS_HOME/user_projects/domains/edq/config/fmwconfig/edq/oedq.home
WLS_HOME/user_projects/domains/edq/config/fmwconfig/edq/oedq.local.home

- If you are using Apache Tomcat, you create the configuration directories manually in any location, with any names, and the configuration utility will populate them. You are prompted to create the directories during the installation instructions.

On a default EDQ installation, the configuration directories occupy approximately 1MB in total. When an EDQ instance uses the landingarea, this total can increase as files are loaded up for processing and written out.

1.4.3 UNIX System Resource Requirements (ulimit)

Depending on how the UNIX system that hosts the application server is configured, you may find that the application server cannot create files larger than 1 GB. This restricts your ability to work with large data sets if you intend to use files to transfer data to EDQ for processing. The most common limit that has to be changed is the number of processes that the application server user (for example. 'weblogic') can create. On large servers, this often needs to be increased, for example to 65536.

System resource limits are controlled by the ulimit command. Default ulimit values exist, which you can view by using the ulimit -a command. Look at the settings for file size, process limit, and file handle limits. The hard ulimit on file size may need to be adjusted upward or removed for your application server account. Consult your System Administrator for assistance, if needed.

1.4.4 Virtual Hardware

You can install EDQ on virtualized systems using a virtualization tool, such as Oracle VM Server. Both the virtual system and the physical system must fulfill the minimum hardware requirements listed in this documentation.

If load balancing software is used to deploy multiple virtual systems onto a single physical system, care must be taken to ensure that the load balancing software is carefully tuned. In general, EDQ requires considerable compute power and memory in the Middle Tier (where it performs most of its processing), and considerable tablespace in the Database (where it writes data and results). Between batches, very little load is imposed on the system. When processing a batch of data, EDQ rapidly drives hardware to be CPU or I/O bound. Unless the virtualized load balancing is correctly configured, suboptimal performance results.

1.4.5 Operating System User

An operating system user account is used to install and upgrade EDQ on your servers and install the application server. This user is required on all platforms. This user must have full permissions (read, write and execute) to the EDQ installation (EDQ_HOME) directory, configuration directories, and all database directories. This user account is referred to as the EDQ installation user in this documentation. For more information about the EDQ directories, see Section 1.4.2, "EDQ Directory Requirements"

Note:
When installing on UNIX or Linux operating systems, do not use the root user as your EDQ installation user account.

1.5 Downloading EDQ

To download the EDQ installation and configuration files, obtain the generic package installer from the Oracle Software Delivery Cloud website as follows:

1. Enter the Oracle Software Delivery Cloud URL into a web browser:

2 Installing the Required External Software Components

This chapter describes how to install the software components that support EDQ.

This chapter includes the following sections:

- Prerequisites for these Procedures

- Installing a Java Development Kit to Support EDQ

- Installing an Application Server to Support EDQ

- Installing a Database to Support EDQ

Note:
These components must be installed prior to installing EDQ.

2.1 Prerequisites for these Procedures

Before performing the procedures in this section, you must first read and satisfy the requirements in Chapter 1, "Planning an Enterprise Data Quality Installation"

2.2 Installing a Java Development Kit to Support EDQ

EDQ and the application server both rely on the Java Development Kit (JDK). The JDK provides a Java run-time environment (JRE) and tools for compiling and debugging Java applications.

Use the following table to identify the appropriate JDK to install on the platform where you are installing EDQ.

Platform

JDK to Use

AIX

IBM JDK. This is the only supported JDK on AIX.

HP-UX

HP JDK

Solaris

Oracle JDK

Linux

Oracle JDK

Windows

Oracle JDK

For supported JDK versions per platform, see the Oracle Enterprise Data Quality Certification Matrix at

http://www.oracle.com/technetwork/middleware/ias/downloads/fusion-certification-100350.html

Download and install the appropriate JDK using the instructions provided at

http://www.oracle.com/technetwork/java/javase/downloads/index.html

Note:
On Solaris systems, you must install both the 32-bit and 64-bit JDKs in order to run Java applications.

Make a note of the directory into which you installed the JDK. You will need to specify this directory during the installation of the application server. The path to this directory is referred to as the JDK_HOME directory in this documentation. For example, the JDK_HOME may be like one of the following:

Linux and UNIX:

/opt/jdk1.8

Windows:

C:\Program Files\Java\jdk1.8

Note:
If your JDK_HOME directory contains spaces, as in the default installation directory of C:\Program Files\Java\jdk1.8, you must set your JAVA_HOME environment variable to the Windows short name for the directory, as follows: C:\Progra~1\Java\jdk1.8.

2.3 Installing an Application Server to Support EDQ

For maximum security, you should configure the application server (whether Oracle WebLogic Server or Apache Tomcat) to use HTTPS only. You should disable unencrypted HTTP access. You can alternatively use a frontend such as Oracle HTTP Server or Apache HTTP Server, where HTTPS is provided.

Choose and download one of the following application servers:

- Installing Oracle Fusion Middleware Infrastructure (includes Oracle WebLogic Server)

- Installing Apache Tomcat

Note:
The application server that you choose determines the database that you can use. With Oracle WebLogic Server, you must use Oracle Database, and you must install EDQ within an Oracle Fusion Middleware environment. With Apache Tomcat, you can use either Oracle Database or PostgreSQL Database, and you can install EDQ as a standalone application. PostgreSQL is not supported for production use.

2.3.1 Installing Oracle Fusion Middleware Infrastructure (includes Oracle WebLogic Server)

When installing on Oracle WebLogic Server, install both Oracle WebLogic Server and JRF. To view the WebLogic Server versions that are supported by EDQ in this release, see Oracle Enterprise Data Quality Certification Matrix at

http://www.oracle.com/technetwork/middleware/ias/downloads/fusion-certification-100350.html

To download and install Oracle WebLogic Server and JRF, see Installing and Configuring Oracle WebLogic Server and Coherence.

Note:
Use the Fusion Middleware Infrastructure installer. Do not use the free WebLogic Server distribution for developers, because this installer does not contain all of the required files for EDQ.

The directory path to your WebLogic Server installation is referenced as the WLS_HOME directory in this documentation.

2.3.2 Installing Apache Tomcat

To view the Tomcat versions that are supported by EDQ in this release, see the Oracle Enterprise Data Quality Certification Matrix at

http://www.oracle.com/technetwork/middleware/ias/downloads/fusion-certification-100350.html

To download and install Apache Tomcat, go to the Apache Software Foundation Server website at

http://tomcat.apache.org

After you install Tomcat, perform the following tasks:

1. Configure Tomcat to use the Java Development Kit (JDK) that you installed in Section 2.2, "Installing a Java Development Kit to Support EDQ" You can do one of the following:

- Set the path to the JDK executable in the /etc/sysconfig/tomcat7.conf file. For example:

JAVA_HOME="/opt/java/jdk1.7.0_45"

- Add the JDK path to the local setenv.sh file.

2. (Recommended) Configure Tomcat to start as a service.

3. Create an operating system user who will run Tomcat. This user must own the EDQ installation and configuration directories. This account is used to administer your EDQ domain and to log into the EDQ application. For more information about the EDQ directories, see Section 1.4.2, "EDQ Directory Requirements"

2.4 Installing a Database to Support EDQ

This section contains information that is specific to the installation and configuration of the database that will contain the EDQ repository.

- If using Oracle WebLogic Server as the EDQ application server, you must install Oracle Database.

- If using Apache Tomcat as the application server, the supported database for production is Oracle Database. PostgreSQL database is supported only for development or test purposes.

To view the supported database versions, see

http://www.oracle.com/technetwork/middleware/ias/downloads/fusion-certification-100350.html

Note:
You will create three schemas and three users in this database when configuring EDQ in Section 4, "Configuring Enterprise Data Quality with Oracle WebLogic Server" or Section 5, "Configuring Enterprise Data Quality with Apache Tomcat" (depending on the application server you chose).

2.4.1 Installing an Oracle Database to Support EDQ

You can download a supported Oracle Database product and installation instructions from the Oracle Database website at

http://www.oracle.com

2.4.1.1 Configuring Oracle Database to Support EDQ

The following configuration elements are either required or recommended when installing or configuring an Oracle database for use with EDQ.

Required:

- Select the Create and configure a database installation option.

- Configure the database to use a Unicode character set to ensure that EDQ is able to capture and process data in the widest range of character sets. For more information, see "Supporting Multilingual Databases with Unicode" in Oracle Database Globalization Support Guide.

- EDQ requires a database administrator (DBA) user account in the database. This database account is used to access the database during the installation and configuration processes to create database accounts and objects that are specific to EDQ.

Recommended:

- Oracle recommends making the following configuration selections when specifying the Oracle memory structure and tablespace configuration to support EDQ:

- 4GB Program Global Area (PGA)

- 4GB System Global Area (SGA)

- 20GB undo tablespace

- 20GB temp tablespace

- 120GB tablespace (4 x 30GB files) for Results database (EDQRESULTS schema)

- 30GB (1 x 30GB file) for Config database (EDQCONFIG schema)

- You may need to increase the values for the SESSIONS and PROCESSES parameters. The suggested values are as follows, but these parameters may need to be adjusted later for optimal performance:
SESSIONS=500

PROCESSES=500

For more information about setting these values appropriately, contact your database administrator.

2.4.2 Installing a PostgreSQL Database to Support EDQ

You can download the PostgreSQL product and installation instructions from the official PostgreSQL website at

http://www.postgresql.org

Note:
If PostgreSQL was distributed with your operating system, verify that the release is one of EDQ supported releases by going to the certification matrix at
http://www.oracle.com/technetwork/middleware/ias/downloads/fusion-certification-100350.html

2.4.2.1 Configuring PostgreSQL Database to Support EDQ

The following configuration elements are either required or recommended when installing or configuring a PostgreSQL database for use with EDQ.

Required:

- Allow 403 maximum connections by editing the postgresql.conf file in the PostgreSQL data directory (for example, var/lib/pgsql/data/postgresql.conf).

- Configure the PostgreSQL database to use a Unicode character set to ensure that EDQ is able to capture and process data in the widest range of character sets. For more information, click the Documentation link on the PostgreSQL website at
http://www.postgresql.org

- To use a PostgreSQL Database with EDQ, you must enable database listening. See Section 2.4.2.2, "Checking Local Database Connections"

- On Linux systems, you must configure PostgreSQL to use password authentication. See Section 2.4.2.3, "Enabling Password Authentication on Linux Systems"

Recommended:

If you are installing on Windows, Oracle recommends that you use the graphical installer that you can download from the PostgreSQL website at

http://www.postgresql.org

Each operating system on the Download page provides a link to the graphical installer.

2.4.2.2 Checking Local Database Connections

This section describes how to ensure that the PostgreSQL database local connections are properly configured to ensure database listening is on and that passwords are accepted for authentication.

1. Log in to the system as the EDQ database user.

2. (Windows only) Locate the MS-DOS Command Prompt (cmd.exe), and then run it.

3. Ensure that your database server is running. For more information, see the PostgreSQL documentation for your installed version on the PostgreSQL website at
http://www.postgresql.org

4. Go to the PostgreSQL data directory. For example, /var/lib/pgsql/data on Linux or C:\Program Files\PostgreSQL\9.3\data on Windows.

5. Open the pg_hba.conf file by entering the one of the following commands, depending on the platform:
On the Linux command line:

tail pg_hba.conf

On the Windows command line:

TYPE pg_hba.conf

The file contents are displayed and the following is an excerpt:

# TYPE  DATABASE        USER            ADDRESS                 METHOD
# "local" is for Unix domain socket connnections only
local  all              all                                     ident

# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
# IPv6 local connections:
host    all             all             ::1/128                 md5

6. Ensure that the IPv4 and IPv6 local connections are configured as shown in the console output in the previous step. Use the address for your own database in the ADDRESS column.

2.4.2.3 Enabling Password Authentication on Linux Systems

On Linux systems, you must configure PostgreSQL to use password authentication by editing the pg_hba.conf file in the data subdirectory of the PostgreSQL installation directory (for example, /var/lib/pgsql/data/pg_hba.conf). Locate the ident sameuser entries, and then change them to a value of md5.

2.4.2.4 Configuring Remote Connections

If your PostgreSQL database is installed on a different system from the one where EDQ is installed, it must be configured to accept connections from other hosts. This is applicable to all PostgreSQL environments.

1. Locate the data directory for your PostgreSQL database.

2. Edit the postgresql.conf file.

3. Locate the following line:
#listen_addresses = 'localhost'

4. Insert the following line to cause PostgreSQL to accept connections from remote hosts:
listen_addresses = '*'

5. Edit the pg_hba.conf file then add the following line using addr/mask to identify the subnet of the host running EDQ:
host all all addr/mask md5

For example, host all all 192.168.0.0/24 md5 allows connections from all hosts with the IP addresses 192.168.0.0 to 192.168.0.255 while host all all 0.0.23.56/32 md5 accepts connections only from IP address 10.0.23.56.

3 Installing Enterprise Data Quality

This chapter describes how to start the Enterprise Data Quality installation program in graphical mode. It also describes the sequence of screens that appear in the installation process.

This chapter includes the following sections:

- Starting the Installation Program

- Navigating the EDQ Installation Screens

- Verifying the Installation

3.1 Starting the Installation Program

The EDQ installation program is delivered as a generic Java Archive (JAR) file that is used to install all supported operating systems.

To start the installation program, perform the following steps.

1. Log in to the target system as your EDQ installation user. This user must be able to run the command prompt as an administrator.

2. Go to the directory where you downloaded and unzipped the installation program.

3. Launch the installation program by invoking java -jar from the JDK installation directory (JDK_HOME) directory on your system as follows:
On UNIX operating systems:

JDK_HOME/bin/java -jar edq_generic.jar

On Windows operating systems:

JDK_HOME\bin\java -jar edq_generic.jar

In the above commands for UNIX and Windows operating systems, edq_generic.jar is a generic place-holder for the actual name of the installation jar file. When the installation program appears, you are ready to begin the installation. See Section 3.2 for a description of each installation program screen.

3.2 Navigating the EDQ Installation Screens

The installation program displays a series of screens. If you need additional help with an installation screen, click Help on the installation screens during installation. Complete the installation using the instructions in Table 3-1, "Running the Installation Program".

4 Configuring Enterprise Data Quality with Oracle WebLogic Server

This chapter describes how to create the EDQ database repository, create an Oracle WebLogic Server domain for EDQ, and start Oracle WebLogic Server.

Note:
These instructions apply to Oracle WebLogic Server environments only. If you are using Apache Tomcat, you must follow the directions in Section 5, "Configuring Enterprise Data Quality with Apache Tomcat"

This chapter includes the following sections:

- Prerequisites for these Procedures

- Creating an EDQ Database Repository

- Creating the WebLogic Server EDQ Domain

- Start Oracle WebLogic Server

- Running Multiple EDQ Servers in the Same Domain

- Configuring EDQ for High-Availability in a WebLogic Server Cluster

4.1 Prerequisites for these Procedures

Before performing the procedures in this section, you must first read and satisfy the steps in:

- Chapter 1, "Planning an Enterprise Data Quality Installation"

- Chapter 2, "Installing the Required External Software Components"

- Chapter 3, "Installing Enterprise Data Quality"

4.2 Creating an EDQ Database Repository

EDQ makes use of some database schemas. These schemas are the configuration schema (EDQCONFIG), the results schema (EDQRESULTS), and the staging schema (EDQSTAGING). You create them with the Oracle Repository Creation Utility (RCU).

The person who runs RCU must be able to log into the database with DBA privileges. If you cannot run with DBA privileges, RCU can create a script for a DBA to run later.

Note:
Do not use RCU to upgrade EDQ; use the instructions in Section 8, "Upgrading Enterprise Data Quality"

To run RCU:

1. Make certain the repository database is running.

2. Run the command shell or console of the operating system.

3. Start RCU from the FMW_HOME/oracle_common/bin directory, where FMW_HOME is the Oracle Fusion Middleware installation directory.
On Linux:

./rcu

On Windows:

rcu.bat

Complete the RCU configuration screens by following the instructions in Table 4-1.

Table 4-1 Running the RCU Program

Screen

Action to Perform

Welcome

Click Next to proceed with the installation.

You may cancel the installation at any time by clicking Cancel.

Create Repository

Click Next to continue.

This uses the default Create Repository and System Load and Product Load options. This requires the person running RCU to have DBA privileges.

Database Connection Details

Select Oracle Database from the Database Type list.

Specify the host name where your Oracle database is running.

Enter the port number for your database. The default port number for Oracle Database is 1521.

Specify the service name for the database. Typically, the service name is the same as the global database name. For example, orcl.example.com.
Note that if you are using release 12c of the Oracle Database, you need to ensure that you enter the connection details of a pluggable database. For example, pdborcl.example.com.

Enter the user name for your database. The user name could either be SYS or that of the user with DBA privileges.

Enter the password for your database user.

Select SYSDBA from the Role list. This is automatically selected when the user is SYS. Select Normal from the Role list if you are a user with DBA privileges.

Click Next to continue.

Checking Global Prerequisites

When the prerequisites checking progress has reached completion, click OK to continue.

Select Components

Select Create new prefix and enter a unique prefix name for all the database schemas you are creating in this session. For example, edqprod or the default of DEV.

Select the Oracle AS Repository Components check box. The Oracle EDQ check boxes that create the EDQ configuration, results, and staging schemas in the database repository are then automatically selected.

When you select the Oracle EDQ component, all the necessary schemas are installed. Not only will the EDQ schema be selected but the common schema needed to support audit and OPSS, which EDQ is integrated with will also be selected. This ensure that EDQ will function correctly with these integrated components.

The three EDQ schemas that are to be installed are Config, Results and Staging. The Staging schema is also used by CDS, with or without the Fusion Connector. However installing the Staging schema when not necessary will not interfere with operation and will consume minimal database resources.

Click Next to continue.

Checking Component Prerequisites

When the prerequisites checking progress has reached completion, click OK to continue.

Schema Passwords

Ensure that Use same passwords for all schemas is selected.

Enter the password that you want to use for all of the EDQ database schemas in all password fields, then click Next to continue.

Map Tablespaces

The default EDQ tablespaces that will be created by RCU are displayed by component.

You can change the tablespaces by clicking Manage Tablespaces and then modifying the information. Oracle recommends using one user tablespace for the EDQCONFIG schema, and a different user tablespace for the EDQRESULTS schema. The recommended minimum sizes (can be adjusted later) are:

- EDQRESULTS: 120GB tablespace (4 x 30GB files)

- EDQCONFIG: 30GB tablespace (1 x 30GB file)

- EDQSTAGING: 30GB tablespace (1 x 30GB file)

Click Next to continue.

Validating and Creating Tablespaces

Click OK to create any non-existent tablespaces in your schema, then click OK when the operation completes.

Summary

Review the database details, then click Create to continue.

A status screen is displayed that shows the progress of creating the repository components.

Completion Summary

Click Close to exit the RCU program.

4.3 Creating the WebLogic Server EDQ Domain

These instructions use the Configuration Wizard to create a Basic WebLogic Server domain for EDQ, with the following:

- One Administration Server and one managed server (no additional managed servers or clusters).

Note:
If there is the possibility you may add more managed servers in the future, you should choose a cluster deployment, even if it starts with a single server. Otherwise it will be necessary to manually re-target the Data Sources, Applications and Deployments in WebLogic from a single server to the cluster.

- One (non-RAC) data source for the EDQ configuration schema, one data source for the results schema, and one data source for the staging schema. You can convert the datasources to RAC data sources with the Configuration Wizard, or you can do so later through the WebLogic Server Administration Console.

- A Node Manager configuration that is predefined within the EDQ domain as edq/nodemanager. You cannot edit the Node Manager home in this configuration. You can change this configuration during this procedure, if desired.

Note:
Oracle recommends the use of managed servers that are administered by Oracle WebLogic Node Manager. You can configure Managed Servers, Clusters, and other advanced features through the Configuration Wizard, but it may be more practical to do so by using the WebLogic Server Administration Console after the initial configuration process. For more information, see Section 4.5, "Running Multiple EDQ Servers in the Same Domain"

4.3.1 Starting the WebLogic Server Domain Configuration Wizard

To start the Domain Configuration wizard, follow these steps. You will run the configuration wizard in graphical mode.

1. Log in to the system as the EDQ installation user that you created in Section 1.4.5, "Operating System User"

2. Go to FMW_HOME/oracle_common/common/bin directory, where FMW_HOME is the Fusion Middleware installation directory.

3. Start the wizard by entering the following command:
On Linux or UNIX operating systems:

./config.sh

On Microsoft Windows operating systems:

config.cmd

The WebLogic Server Configuration Wizard is displayed.

4.3.2 Navigating the Domain Configuration Wizard Screens

Table 4-2 describes the screens in the configuration wizard. Certain screens are displayed only in certain situations depending on your selections. For help with any screen, click the Help button.

Click Next to continue.

Domain Mode and JDK

Domain Mode: Select the startup operation mode for your domain from the following options:

- Development Mode—In this mode, the security configuration is relatively relaxed and you utilize boot.properties for the username and password, allowing you to auto-deploy applications.

- Production Mode—In this mode, the security configuration is relatively stringent, requiring a username and password to deploy applications. Before putting a domain into production, familiarize yourself with procedures for securing a production environment. For more information, see Securing a Production Environment for Oracle WebLogic Server.

JDK: From the Available JDKs list, select the JDK that you installed in Section 2.2, "Installing a Java Development Kit to Support EDQ"

Click Next to continue.

Database Configuration Type

Ensure that RCU Data is selected. This populates the connection information you supplied when you ran the Repository Creation Utility (see Section 4.2, "Running the RCU Program").

If you must change any of these fields, ensure that you use the schema prefix (DEV by default) and password that you specified when you ran RCU.

When done, click Get RCU Configuration to connect to the Oracle Database and bind the EDQ schemas.

Click Next to continue.

Component Datasources

Accept the defaults and then click Next.

Administration Server

On the Administration Server screen, change the listen address from "All Local Addresses" to the IP address of the host where the Administration Server will reside.

Do not use All Local Addresses.

Do not specify any server groups for the Administration Server.

Node Manager

Let the Per Domain Default Location option remain selected, and enter a Username and Password for the Node Manager.

Managed Servers

Clone the EDQ server to create a copy of the server.

If you do not want to clone the EDQ server, select Add to add additional EDQ servers.

Select the IP address of the host on which the Managed Server will reside.

For configuration procedures for a clustered mode installation, see Section 4.6, "Configuring EDQ for High-Availability in a WebLogic Server Cluster"

Clusters

Select Add to add a cluster. If both servers are being deployed on the same machine, enter the machine name as the cluster address.

For additional configuration procedures for a clustered mode installation and a description of those configuration screens, see Section 4.6, "Configuring EDQ for High-Availability in a WebLogic Server Cluster"

To deploy EDQ in a non-clustered mode, select the appropriate components as needed.

Assign Servers to Clusters

Assign the managed servers that you created to the cluster that you created.

For configuration procedures for a clustered mode installation, see Section 4.6, "Configuring EDQ for High-Availability in a WebLogic Server Cluster"

Coherence Clusters

Configure the Coherence cluster that is automatically added to the domain.

Leave the default port number 7574 as the Coherence cluster listen port.

Machines

Create a new machine in the domain. A machine is required so that the Node Manager can start and stop servers.

Click Add to create a new machine.

Specify edq_machine_1 in the Name field.

In the Node Manager Listen Address field, select the IP address of the machine in which the Managed Servers are being configured. You must select a specific interface and not "localhost." This allows Coherence cluster addresses to be dynamically calculated.

Verify the port in the Node Manager Listen Port field. The port number 5556, shown in this example, may be referenced by other examples in the documentation. Replace this port number with your own port number as needed.

Assign Servers to Machines

Assign the Administration Server and Managed Servers to the new machine you just created.

In the Machines pane, select the machine you want to assign the servers to; in this case, edq_machine_1.

In the Servers pane, assign AdminServer to edq_machine_1 by doing one of the following:

- Click once on AdminServer to select it, then click on the right arrow to move it beneath the selected machine (edq_machine_1) in the Machines pane.

- Double-click on AdminServer to move it beneath the selected machine (edq_machine_1) in the Machines pane.

Repeat to assign both edq_server_1 and edq_server_2 to edq_machine_1.

Virtual Targets

Add or delete Virtual Targets for use in a WebLogic Server Multitenant (MT) environment.

Virtual targets define the locations where a partition or resource group runs. They also provide instructions on how to route traffic, including addresses, protocol settings, and targeting. Request routing is determined by the host name and optional URI.

Partitions

For each partition you want to add, click Add and enter the name you want to use for the partition. The partition name must be unique within the domain.

Configuration Summary

Review the configuration for your domain by selecting a view and then selecting individual items in the list for that view.

If the domain is configured as you want it, click Create to create the domain.

If you need to make changes to the configuration, click Back to return to the appropriate screen for the settings you want to change, or click on the links on the left to go to that screen.

Click Finish to exit the Configuration Wizard.

4.3.3 Configuring Launchpad to Show the Managed Server

To configure a launchpad to show the managed server that it is connected to, add this line to the director.properties in the local home directory:

[expr]adf.headerextra = ': ' || weblogic.Name

4.4 Start Oracle WebLogic Server

You must start your Administration Server, Managed Servers, and clusters to complete the installation. For information about starting managed servers using Node Manager and Administration Servers, see "Starting and Stopping Oracle WebLogic Server Instances" in Oracle Fusion Middleware Administering Server Startup and Shutdown for Oracle WebLogic Server.

See also Section 6, "Setting Server Parameters to Support Enterprise Data Quality" for important information about setting server parameters for startup.

4.5 Running Multiple EDQ Servers in the Same Domain

To support high availability scenarios, Oracle recommends that you configure a cluster of multiple EDQ servers to share the incoming load (for example, from a large number of simultaneous web service requests), and to provide continuous service in the event of failure of an individual server. This section provides some basic guidance about how to configure EDQ to support such a model using Oracle WebLogic Server.

Multiple EDQ managed servers can be configured to run in the same WebLogic Server domain either in a cluster or not. If all the servers are on the same machine, each server must listen on a different port.

The Java Required Files (JRF) Template must be applied to any managed servers that were created using the WebLogic Server Administration Console. This is equivalent to the library targeting performed automatically by the WebLogic Server Configuration Wizard.

The final step is:

- Use the WebLogic Server Administration Console to modify the managed server settings for the additional EDQ servers.

Once multiple EDQ servers have been configured, you can leave them un-clustered and accessed directly using their respective Launchpad URLs to the relevant port, or you can configure them as part of a cluster using standard WebLogic Server practices. You can configure a separate front-end load balancer to handle incoming web service requests through a single cluster URL.

4.6 Configuring EDQ for High-Availability in a WebLogic Server Cluster

You can install and configure Oracle Enterprise Data Quality for high availability in an Oracle WebLogic Server cluster environment. The high availability features in Oracle Enterprise Data Quality have been enhanced to make the system function in a clustered environment, and tolerate individual RAC node failures and reconnect after complete database failures.

For more information on the high-availability features in Enterprise Data Quality, please see Oracle Fusion Middleware Understanding Oracle Enterprise Data Quality.

4.6.1 Configuring EDQ for Clustered Mode Deployment

To install and configure Oracle Enterprise Data Quality for high availability in an Oracle WebLogic Server cluster environment:

- Plan the installation, and install the prerequisites and software, as described in Chapter 4, "Prerequisites for these Procedures".

- Run the Repository Creation Utility (RCU), as described in Section 4.2, "Creating an EDQ Database Repository". To get a full high availability implementation, you must deploy the schema to an Oracle RAC instance. Deploying to a standard Oracle database does not provide HA capability for the database.

- Run the Domain Configuration wizard to provision a domain, as described in Section 4.3, "Creating the WebLogic Server EDQ Domain" and with the configuration steps for a cluster noted in Section 4.6.1.1, "Running the Domain Configuration Wizard for a Clustered Deployment".

- Start EDQ in a cluster as described in Section 4.6.2, "Starting EDQ in a Cluster".

- Enable or configure options for high availability in EDQ. See the sections:

- Section 4.6.3, "Enabling JMX API and Command Line for HA Clusters"

- Section 4.6.4, "Landing Area"

4.6.1.1 Running the Domain Configuration Wizard for a Clustered Deployment

To deploy EDQ in a clustered mode using the schema you created in the RCU:

1. Follow the steps in Section 4.3.1, "Starting the WebLogic Server Domain Configuration Wizard" and Section 4.3.2, "Navigating the Domain Configuration Wizard Screens" to launch and configure the basic configuration screens in the Domain Configuration wizard.

2. On the Advanced Configuration screen, select the Topology option and then select Next. In the Topology option, you can Add, Delete or Modify settings for Server Templates, Managed Servers, Clusters, Virtual Targets and Coherence.

3. On the Manage Servers screen, select the EDQ server, for example "edq_server1", and select the Clone button to create a copy of the server. If you do not want to clone the server, select the Add button to add a new server and target it to the cluster.
Name this server appropriately, for example "edq_server2".

The listen port should not be the same port as in Server 1 and the Server Group should be EDQ Managed Server. The listen address should be the same as server 1, assuming they are both running on the same machine.

Click Next and move to the Clusters screen.

4. Select the Add button to add a cluster.
If servers are being deployed on the same machine, enter the machine name as the cluster address. If not, the cluster address should be a comma-separated list of the machine names.

Leave the frontend host blank if you are not deploying a load balancer. If you are deploying with a load balancer, enter the URL of the load balancer.

Click Next.

5. On the Assign Servers to Clusters screen, assign both the servers that have been created to the cluster that you have just created.

6. Step through the Coherence Clusters screen.

7. On the Machines screen you can add machines in the cluster, and allocate managed servers to them. The AdminServer does not need to be allocated to a machine since it is started manually via the startWebLogic.sh script and is not managed by the Node Manager.

8. Step through the remaining screens and select Create to create the cluster.

4.6.2 Starting EDQ in a Cluster

Once the domain has been created, start the Admin Server by running the following command:

FMW_HOME/user_projects/domains/edq_domain/bin/startWebLogic.sh

If you select Production Mode for the Domain Mode and JDK screen when you create the domain, you will be prompted for the Administrator user login credentials. Enter the same credentials that you received in the Administrator Account screen

Then start the Node Manager with the command:

FMW_HOME/user_projects/domains/edq_domain/bin/startNodeManager.sh

You can then log onto the Admin Console through a browser and start both of the Managed servers that were created during the configuration steps.

You can access the servers as follows:

- You can access any of the servers' launchpads. Connect to one of the servers and start the Director application. Or,

- You can connect via a load balancer in front of the cluster, and will be connected to whichever managed server the load balancer picks.

To display a dialog indicating which server the GUI is connected to, right-click the server in the project browser and select Server Information.

4.6.3 Enabling JMX API and Command Line for HA Clusters

The EDQ high availability deployment templates come with the internal JMX server disabled. This is to prevent port clashes between multiple managed servers which are running on the same host. Since the internal JMX server is not running the various command line tools which use this API, it will be unable to access the server. In particular the command line tools for starting and cancelling jobs will not work.

To enable these tools the internal JMX server must be re-enabled. This is achieved by editing the director.properties file in the oedq.local.home directory. Add the following line to the director.properties file:

management.localserver = "true"

This line enables the JMX server. By default the JMX server runs on port 8090. If multiple EDQ managed servers will run on the same host then you must configure each server to use a different port number.

Provided the EDQ managed servers are named with a number at the end, such as 'edq_server1', 'edq_server2', etc. (this is the default naming scheme), adding the line:

management.port = 8090 + servernum - 1

to the same director.properties file will cause the first EDQ managed server to run the JMX server on port 8090, the second server to run it on port 8092 and so on.

4.6.4 Landing Area

The landing area is a feature that allows EDQ to read and write data to server file system. If the landing area is to be used in a cluster then some consideration needs to be given as to how the landing area is shared amongst the managed servers. By default the landing area is located in the oedq.local.home area. If this is shared amongst the various hosts supporting EDQ managed servers then the landing area will continue to work as in a non-clustered system.

If the landing area file system is not shared amongst the managed servers, but is required for use then a number of options are available:

- The location of the landing area can be changed using the landingarea property in the director.properties file to a location that is shared amongst the hosts running EDQ managed servers.

- Since an EDQ job runs all its tasks and processes on the same managed server, any files consumed or generated by the job are written to its local landing area. External tasks can be added to the job to transfer any incoming or outgoing files to an appropriate shared location.

- If an EDQ job is consuming external files then these could be copied to all managed servers before the job is started.

- If an EDQ job is generating files for consumption by further EDQ jobs then the landing area can be synchronized across the various managed server between the various job run by use of an external tool such as rsync.

If files are being generated and consumed within the same job then a shared landing area may not necessary. This is because the entire job will run on the same managed server and so access the local landing area.

5 Configuring Enterprise Data Quality with Apache Tomcat

This chapter describes how to configure EDQ and the database to operate with a Tomcat Application Server and perform the necessary additional configuration steps.

Note:
These instructions apply to Apache Tomcat environments only. If you are using Oracle WebLogic Server, you must follow the directions in Section 4, "Configuring Enterprise Data Quality with Oracle WebLogic Server"

This chapter includes the following sections:

- Prerequisites for these Procedures

- Creating the EDQ Database Objects

- Configuring Tomcat Application Server

- Creating Directories for Use With Tomcat Application Server

- Configuring EDQ to work with Tomcat Application Server

- Verifying EDQ Functional Packs

- Deploying the EDQ Application on a Tomcat Application Server

5.1 Prerequisites for these Procedures

Before performing the procedures in this section, you must first read and satisfy the steps in:

- Chapter 1, "Planning an Enterprise Data Quality Installation"

- Chapter 2, "Installing the Required External Software Components"

- Chapter 3, "Installing Enterprise Data Quality"

5.2 Creating the EDQ Database Objects

EDQ requires three database accounts and three schemas. The first schema contains configuration data, the second contains results data, and the third contains staging data. These objects must be created in the database that you installed as the EDQ repository in Section 2, "Installing the Required External Software Components"

5.2.1 Creating an EDQ Repository in an Oracle Database

This procedure configures an Oracle database as the repository for EDQ.

1. Create three database accounts named edqconfig, edqresults, and edqstaging or other names of your choosing. When selecting names, consider that one schema will be the configuration schema and the other will be the results schema.

2. Grant the following privileges to each of these accounts:

- CREATE SESSION (normally granted by CONNECT)

- CREATE INDEXTYPE (normally granted by RESOURCE)

- CREATE SEQUENCE (normally granted by RESOURCE)

- CREATE TABLE (normally granted by RESOURCE)

- CREATE TYPE (normally granted by RESOURCE)

- CREATE INDEX

- DROP TABLE

- DROP INDEX

- UNLIMITED TABLESPACE (recommended to allow the auto-extension of tablespace)

5.2.2 Creating an EDQ Repository in a PostgreSQL Database

This procedure configures a PostgreSQL database as the repository for EDQ.

1. Create three EDQ users named edqconfig, edqresults, and edqstaging or other names of your choosing.

2. Grant the database administrator (DBA) privilege to the users that you created.

3. Create the following schemas:

- A schema named edqconfig or another name of your choosing. This schema must be owned by the first user you created and will contain the configuration data.

- A schema named edqresults or another name of your choosing. This schema must be owned by the second user that you created and will contain the results data.

- A schema named edqstaging or another name of your choosing. This schema must be owned by the third user that you created and will contain the staging data.

4. Test your database configuration by logging out, then back in, using the credentials for the new EDQ users.

5.3 Configuring Tomcat Application Server

Create the necessary Oracle Application Development Framework (ADF) shared library:

1. Create a lib.adf ADF shared directory in your Tomcat directory.

2. Unzip the adf-essentials.zip file, delivered with the EDQ product, into the lib.adf directory. The JAR files in this zip file must be in the lib.adf directory, not the adf-essentials directory that it unzips to by default.

3. Configure the Tomcat common.loader property (typically located in the catalina.properties file) to load Oracle ADF from their respective shared library paths. For example:

common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,
${catalina.home}/lib,${catalina.home}/lib/*.jar,
${catalina.home}/lib.adf/*.jar

5.4 Creating Directories for Use With Tomcat Application Server

Create two empty directories to contain your EDQ configuration files. For example:

On Linux and UNIX operating systems:

/opt/edqconfig/oedqhome

/opt/edqconfig/oedqlocalhome

On the Windows operating system:

C:\edqconfig\oedqhome

C:\edqconfig\oedqlocalhome

The first directory (oedqhome) is the base configuration directory and will contain the configuration files that should not be changed post-installation. The second directory (oedqlocalhome) is the local configuration directory and will contain any custom settings that you create. Ensure that your application server user has read and write access to the two directories you create. For more information about these directories, see Section 1.4.2, "EDQ Directory Requirements"

5.5 Configuring EDQ to work with Tomcat Application Server

Follow these steps to run the EDQ Configuration Application (configapp) to configure EDQ to work with Apache Tomcat and to populate the repository schemas with the required EDQ objects.

Note:
These instructions assume you have created the required database schemas as directed in Section 2, "Installing the Required External Software Components"

To start the EDQ Configuration Application, follow these steps:

1. Log in to the system as your EDQ installation user.

2. Go to your FMW_HOME/edq/oracle.edq directory.

3. Start the Configuration Application by entering the following command:
java -jar configapp.jar

- All Functional Packs are needed if you want to use the full capabilities of the EDQ Customer Data Services Pack on your EDQ server, such as for integration with Siebel Customer Relationship Management or Universal Customer Master.

- All Functional Packs are needed if you want to install Oracle Watchlist Screening on your EDQ server.

5.7 Deploying the EDQ Application on a Tomcat Application Server

The EDQ application must be manually deployed on Tomcat Application Servers.

1. Stop the application server.

2. Deploy the edq.war file on your application server.
See the Tomcat Web Application Deployment web page at

http://tomcat.apache.org/tomcat-8.0-doc/deployer-howto.html

3. To link EDQ to the base and local configuration directories that you created in Section 5.4, you can do one of the following:

- On any of the EDQ-supported platforms, you can use a Java property named -Dedq.config.path that specifies the paths to those directories. The syntax is as follows, where path_to_base_config is the path to the base configuration directory and path_to_local_config is the path to the local configuration directory.
Linux and UNIX (colon separates the paths):

-Dedq.config.path=path_to_base_config:path_to_local_config
-Doracle.mds.cache=simple

Windows (semi-colon separates the paths):

-Dedq.config.path=path_to_base_config;path_to_local_config
-Doracle.mds.cache=simple

- On Windows, you can append an environment variable named EDQ_CONFIG_PATH to your JAVA_OPTS environment variable, as shown in the following, where path_to_base_config is the path to the base configuration directory and path_to_local_config is the path to the local configuration directory.

EDQ_CONFIG_PATH="path_to_base_config;path_to_local_config"

For more information about setting Java parameters, see the Apache Tomcat Documentation website at

http://tomcat.apache.org/

4. Restart your application server service and ensure that edq.war is successfully deployed.

6 Setting Server Parameters to Support Enterprise Data Quality

This chapter contains recommended Managed Server parameter settings for the framework that supports EDQ. These settings apply to both Oracle WebLogic Server and Apache Tomcat application server environments.

This chapter contains the following topics:

- How to Set the Server Parameters

- Recommended Parameter Values

- Example of Parameter Settings

6.1 How to Set the Server Parameters

This section describes how to set the recommended server parameters for WebLogic Server and Tomcat domains. Follow the guidelines that are appropriate for your EDQ installation.

6.1.1 How to Set Server Parameters in a WebLogic Server Domain

When you start a Managed Server in a WebLogic Server domain, the startup passes a set of configuration parameters to initialize a Java Virtual Machine (JVM). These parameters include, but are not limited to, the server's JVM settings and the path to the server configuration directories.

The method of setting the required server configuration parameters for EDQ varies, depending on the method that you use to start the Managed Servers. The following points explain the differences:

- When starting an EDQ Managed Server from the WebLogic Server Administration Console, the configuration settings for the Managed Server are pre-defined as server startup arguments, because they were set by the domain Configuration Wizard (see Section 4.3). When starting the server, these arguments are applied by default, but you can change them to the recommended settings described in Section 6.2.

- When starting an EDQ Managed Server by using a startup script, the server startup arguments that are defined in the WebLogic Server Administration Console are ignored. However, when the domain Configuration Wizard was run, it created an edq_server1 Managed Server that contains default JVM settings. These settings are stored in the setStartupEnv.cmd (Windows) or setStartupEnv.sh (Linux) script. You can edit this script to add or change the name of the Managed Server and to apply the recommended JVM settings described in Section 6.2.

6.1.2 How to Set Server Parameters in a Tomcat Domain

Consult the Tomcat documentation for your version of the application server. Documentation for all versions of Tomcat are at

http://tomcat.apache.org

6.2 Recommended Parameter Values

This section describes the recommended server parameter settings.

6.2.1 Setting JVM Parameters

You must set the following parameters for the Java Virtual Machine (JVM) that runs the EDQ environment. Most of these parameters apply to the HotSpot JVM, which is the central JVM of the Java Development Kit (JVM) from Oracle. This is the preferred JVM because it yields the best performance for EDQ.

- Maximum heap memory, -Xmx, should normally be set to approximately 50% of available physical memory on the host server. For example, on a server with 32GB of RAM, start by setting it to 16GB with -Xmx16384m. Depending on the relative usage of memory between the JVM and native processing, you may need to be adjust this setting. This parameter is common to most JVMs.

- Reserved Code Cache size should be set to 128m, -XX:ReservedCodeCacheSize=128m, unless otherwise advised. This parameter is specific to HotSpot JVM.

6.2.2 Setting Other Parameters

The following additional parameter setting is recommended.

- Headless mode should always be set to true on UNIX systems, -Djava.awt.headless=true. This parameter is specific to the Java Abstract Window Toolkit (AWT) library. Setting this is recommended because some of the graphic drawing routines (such as around graphs) will attempt to connect to the display device on a client to size fonts and other attributes. If the machine does not have a display device, this may interfere with operation. The headless=true setting directs the graphics library to operate without connecting to a display.

6.3 Example of Parameter Settings

The following is an example of the full set of recommended parameter options for a typical UNIX or Linux server with 32GB of RAM:

-Xmx16384m
-XX:ReservedCodeCacheSize=128m
-Djava.awt.headless=true

7 Next Steps After Configuring Enterprise Data Quality

This chapter describes how to start using EDQ and is intended to help you become familiar with the main components of EDQ.

This chapter includes the following sections:

- Logging Into EDQ

- The EDQ Launchpad

7.1 Logging Into EDQ

You can access the EDQ Launchpad and client applications by starting a supported browser and enter the following URL:

http://server_name:port_number/edq

where server_name is the name of the server onto which you installed EDQ and port_number is the HTTP or HTTPS port that your application server is running against (8001 on WebLogic Server by default, 8080 on Tomcat). If you deployed the application server to run against a different port, you should use that port number.

Enter your login credentials for the appropriate application server:

WebLogic Server Login

Use the WebLogic Server user that you created in Section 4.3.2, "Navigating the Domain Configuration Wizard Screens"

Tomcat Login

Use the default EDQ administrator account dnadmin with the password dnadmin. You are prompted to change the password the first time you log in. This password must meet the default security standards.

7.2 The EDQ Launchpad

The Launchpad provides access to the EDQ client applications, services, and system management. The following may be displayed on the Launchpad when EDQ is installed:

Director

Starts the Director client application, which is the main configuration application.

Server Console

Allows you to perform the following tasks:

- Schedule jobs

- View current tasks

- View the event log

- View job results

Dashboard

Starts the Dashboard, where published data quality metrics are displayed.

Match Review

Starts the Match Review application, which allows users to view an overview of the reviews assigned to them and to launch the review application.

Case Management

Case Management is an application designed to support the manual investigation of results from data quality processes. It is also used as the main investigation application in Oracle Watchlist Screening, for both batch and real time screening results. Using Case Management, privileged users can manage and review matching results using highly configurable workflows with a comprehensive audit history of all investigation work.

Case Management Administration

Case Management Administration provides the following areas of functionality:

- Workflow Administration—allows you to create, edit, copy, import, export and delete workflows.

- Case Source Administration—allows you to import, export and delete case source definitions.

- Permission Administration—allows you to define and manage the data that users have permission to access.

Administration

This application allows a sufficiently privileged user to configure EDQ users, permission groups, password and security rules, extensions, functional packs, the applications that appear on the launchpad, and the ability to view and monitor sessions.

Web Services

Displays details of the web services configured in the EDQ server, and allows access to the web service tester.

Login

An explicit Login button in the upper right corner. Upon logging in the full list of pages available to the user is displayed. Once the user is logged in they have access to a user menu by clicking on their user name in the top right of the screen. This provides access to log out and change password functionality (change password is only shown if using an internal realm).

Change Password

Allows users to change their passwords. A user must log in with the existing password and then provide and confirm the new password. This option is not available when using a WebLogic Server.

Help

Allows you to retrieve information about how to use each EDQ application.

An Administrator can reconfigure the Launchpad to define the user applications and links that are displayed to users by using the Administration pages. For more information, see the Oracle Enterprise Data Quality Online Help.
