Oracle JD Edwards

1 Introduction

Oracle’s JD Edwards EnterpriseOne is an integrated applications suite of comprehensive enterprise resource planning software that combines business value, standards-based technology and deep industry experience into a business solution with a low total cost of ownership.

JD Edwards EnterpriseOne offers a choice of databases, operating systems and hardware to build and expand an IT solution to meet business requirements. JD Edwards delivers over 80 application modules to support a diverse set of business processes and key industry solutions such as Consumer Package Goods, Manufacturing, Asset Intensive and Projects and Services.

The Kemp LoadMaster can be used to enable scalability, load balancing and High Availability (HA) for JD Edwards environments. The diagram above shows an example network architecture where the LoadMaster is balancing traffic between two application servers.

1.1 Document Purpose

The purpose of this document is to explain how to add and configure a Virtual Service in the LoadMaster to load balance JD Edwards traffic. For further information and step-by-step instructions on LoadMaster functionality in general, such as HA, please refer to the Kemp documentation web page: http://kemptechnologies.com/documentation/.

1.2 Intended Audience

This document is intended to be used by anyone who is interested in finding out how to use a Kemp LoadMaster to load balance the Oracle JD Edwards EnterpriseOne workload.

1.3 Prerequisites

LoadMaster firmware version 7.16 or above should be installed.

2 Template

Kemp has developed a template containing our recommended settings for this workload. You can install this template to help create Virtual Services (VSs) because it automatically populates the settings. You can use the template to easily create the required VSs with the recommended settings. You can remove templates after use and this will not affect deployed services. If needed, you can make changes to any of the VS settings after using the template.

Download released templates from the Templates section on the Kemp Documentation Page.

For more information and steps on how to import and use templates, refer to the Virtual Services and Templates, Feature Description on the Kemp Documentation Page.

3 Configure the LoadMaster

3.1 Enable Subnet Originating Requests Globally

It is best practice to enable the Subnet Originating Requests option globally.

In a one-armed setup (where the Virtual Service and Real Servers are on the same network/subnet) Subnet Originating Requests is usually not needed. However, enabling Subnet Originating Requests should not affect the routing in a one-armed setup.

In a two-armed setup where the Virtual Service is on network/subnet A, for example, and the Real Servers are on network B, Subnet Originating Requests should be enabled on LoadMasters with firmware version 7.1-16 and above.

Because this application can run at Layer 4, transparency is enforced. Transparency takes a higher priority than Subnet Originating Requests. Therefore, if transparency is enabled on the Virtual Service and Subnet Originating Requests is enabled globally, the Virtual Service still uses transparency. The Real Server sees traffic from this virtual service originating with the client’s source IP address (transparency). See the Transparency document on the Kemp documentation page for more details.

In the diagram above, you can see the following details:

  • Client: 10.0.0.100/24
  • Virtual Service on eth0: 10.0.0.15/24
  • Real Server on eth1: 10.20.20.25/24

With Subnet Originating Requests enabled, the Real Server sees traffic originating from 10.20.20.21 (LoadMaster eth1 address) and responds correctly.

With Subnet Originating Requests disabled, the Real Server sees traffic originating from 10.0.0.15 (LoadMaster Virtual Service address on eth0) and responds to eth0 causing asymmetric routing

When Subnet Originating Requests is enabled globally, it is automatically enabled on all Virtual Services. If the Subnet Originating Requests option is disabled globally, you can choose whether or not to enable Subnet Originating Requests on a per-Virtual Service basis.

To enable Subnet Originating Requests globally, follow the steps below:

1. In the main menu of the LoadMaster Web User Interface (WUI), go to System Configuration > Miscellaneous Options > Network Options.

2. Select the Subnet Originating Requests check box.

3.2 Create a Content Rule (Header Modification)

The Kemp LoadMaster supports content switching, sometimes referred to as URL switching. This allows the LoadMaster to direct specific requests to specific Real Servers based on the contents of the requested URL.

Content switching can be very useful if there are dedicated server types that perform different functions such as image servers, static content servers, mapping servers, specialized content servers, application servers and media servers, that all need to be served from the same general hostname, for example www.mysite.com. Content switching also allows for hostname-specific servers and source IP-specific servers.

Content rules give the ability to:

  • Strip out server information
  • Redirect requests for the root of a server
  • Rewrite redirections from HTTP to HTTPS
  • Force connections to close
  • Secure cookies

The following content rule, which can be used when configuring a Virtual Service with or without SSL offloading, writes the URL so that users are sent to the domain.com/JDE_Hompage rather than the default homepage of the server:

Create a Content Rule Header.png

1. In the main menu, select Content Rules > Create New.

2. Enter a recognisable Rule Name in the text box.

3. Select Modify URL from the Rule Type drop-down list.

4. Enter /^\/$/ in the Match String text box.

5. Enter /jde/E1menu.maf in the Modified URL text box.

6. Select [Unset] from the Perform If Flag Set drop-down list.

7. Click the Create Rule button.

3.3 Configure the Virtual Service

3.3.1 Configure the Virtual Service without SSL Offloading for Oracle JD Edwards

This example configuration assumes that one Virtual Service and one Real Server are being set up. In a real situation, users may need to configure more.

To add and configure the Oracle JD Edwards without SSL Offloading Virtual Service, follow the steps below in the LoadMaster Web User Interface (WUI):

1. Add a Virtual Service:

Configure the Virtual Service_1.png

2. In the main menu, go to Virtual Services > Add New.

3. Enter a valid IP address in the Virtual Address text box.

4. Enter 80 as the Port.

5. Enter a recognizable Service Name, such as Oracle JD Edwards EnterpriseOne HTTP.

6. Ensure tcp is selected as the Protocol.

7. Click Add this Virtual Service.

8. Add the Content Rule to the Virtual Service.

9. Expand the Advanced Properties section.
