1 Overview

This chapter provides an overview of using Oracle WebLogic Server on Oracle Database Appliance and describes how to prepare for the WebLogic Server installation.

Oracle Database Appliance is server, storage, and network hardware, combined with network, cluster, and database software and templates. Oracle fully supports all hardware and software components. The hardware and software are engineered together to be simple to configure and maintain, and to be pre-configured for specific database workloads. Oracle Database Appliance is designed to minimize cost, time, and risk in database deployment and maintenance.

Oracle Database Appliance also supports WebLogic Server clusters. By downloading and installing Oracle Virtual Machine (OVM) templates that provide WebLogic Server and Oracle Traffic Director, you can quickly configure and provision highly-available WebLogic domains using the Oracle WebLogic Server Configuration for Oracle Database Appliance utility.

In this configuration

Both the database and WebLogic Server run on virtual machines (VMs)
The database has direct access to storage
WebLogic Server high availability is delivered via clustering, with transaction logs and JMS persistence configured in the database on Oracle Database Appliance. Transaction logs and JMS are configured only if JMS is selected in the configurator.
The WebLogic Server Administration Console can be used to manage the environment

The following sections are included in this chapter:

"Installation Prerequisites"
"Hardware Configuration"
"Virtual Machine Topology"

Installation Prerequisites

To use WebLogic Server on Oracle Database Appliance, you must download and install:

Oracle WebLogic Server Configuration for Oracle Database Appliance utility
Oracle WebLogic Server on Oracle Database Appliance Kit, either for WebLogic Server 10.3.6 or WebLogic Server 12.1.1 or WebLogic Server 12.1.2 or WebLogic Server 12.1.3

Prior to downloading and installing these items, you must complete the following prerequisite tasks as described in Oracle Database Appliance Getting Started Guide. Refer also to the Oracle Database Appliance Setup poster:

connecting all hardware.
configuring a network to transfer the end-user bundle.
configuring Oracle Database Appliance using the configuration utility.
completing Oracle Database Appliance post-installation tasks.

After completing these tasks, see Chapter 2, "Installation and Configuration," for instructions on how to download the support files and the Oracle WebLogic Server Configuration for Oracle Database Appliance utility.

Hardware Configuration

For the hardware specifications for your Oracle Database Appliance, see "Hardware Capacity Specifications" in the Oracle Database Appliance Getting Started Guide.

For supported configuration information for WebLogic Server, see the Oracle Fusion Middleware Supported Configurations page on the Oracle Technology Network at:

Virtual Machine Topology

The virtual machine topology for using WebLogic Server on Oracle Database Appliance consists of the following components:

Multiple WebLogic Server Administration Servers VM - one for each domain
Up to sixteen WebLogic Managed Server VMs
An Oracle Traffic Director Administration Server VM
Two Oracle Traffic Director Administrator Node VMs for load balancing
