Oracle Application Server 10g Release 3 (10.1.3.0.0) was a significant new release that provided a complete Java 2, Enterprise Edition (J2EE) 1.4-compliant environment.
Oracle Application Server 10g Release 3 (10.1.3.1.0) is an update to the 10g Release 3 (10.1.3.0.0) release that improves the reliability and performance of 10g Release 3 (10.1.3.0.0) and provides some additional functionality.
As with 10g Release 3 (10.1.3.0.0), 10g Release 3 (10.1.3.1.0) does not include all the Oracle Application Server components that were available with 10g (9.0.4) and 10g Release 2 (10.1.2).
Oracle Application Server 10g Release 3 (10.1.3.1.0) is designed specifically:
For administrators who are using OC4J to deploy and manage J2EE applications
As a platform for developing and deploying Service Oriented Architecture (SOA) applications
Refer to the following sections for more information:

This document describes how to redeploy your Oracle Application Server 10g (9.0.4) and 10g Release 2 (10.1.2) J2EE applications in a new Oracle Application Server 10g Release 3 (10.1.3.1.0) environment.
If you are using Oracle Application Server Release 2 (9.0.2) or earlier, then you must upgrade your environment to 10g (9.0.4) or 10g Release 2 (10.1.2) before using the instructions in this guide.

If you are using Oracle Application Server 10g Release 3 (10.1.3.0.0), apply 10g Release 3 (10.1.3.1.0) Patch Set 1 to your exisiting 10g Release 3 (10.1.3.0.0) Oracle home directories.

Before you begin the upgrade process, you should be familiar with your current Oracle Application Server environment. For example, you should be able to answer the following questions:
How many 10g (9.0.4) or 10g Release 2 (10.1.2) middle tiers are installed in your environment?
Are your middle tiers part of an Oracle Application Server Farm? In other words, are they using the same OracleAS Metadata Repository?
Are you using Oracle Application Server Clusters to manage multiple J2EE and Web Cache installations?
Are you using state replication for your deployed applications?
Are you taking advantage of OracleAS Identity Management components, such as Oracle Internet Directory?
What J2EE features do your deployed applications rely upon (for example, JDBC, JMS, Java Transaction Manager)?
What customizations have you made to your Oracle HTTP Server and Oracle Containers for J2EE (OC4J) configuration files, such as the httpd.conf file and server.xml?
If you have answers to these types of questions, then it will be easier to select an equivalent topology for your new 10g Release 3 (10.1.3.1.0) environment and to perform any configuration tasks that might be required before you can deploy your 10g (9.0.4) or 10g Release 2 (10.1.2) application on 10g Release 3 (10.1.3.1.0).
Unlike the upgrade to previous versions of Oracle Application Server, such as 10g Release 2 (10.1.2), the upgrade to 10g Release 3 (10.1.3.1.0) does not involve any specific upgrade tools.
Instead, you use Oracle Universal Installer to install a new 10g Release 3 (10.1.3.1.0) environment, make any necessary configuration changes, verify that your applications are compatible with 10g Release 3 (10.1.3.1.0), and then redeploy your 10g (9.0.4) and 10g Release 2 (10.1.2) applications on 10g Release 3 (10.1.3.1.0).
Before redeploying your applications on 10g Release 3 (10.1.3.1.0), be sure to closely follow the instructions in this guide, including the considerations listed in Appendix C, "Things to Consider When Redeploying 10g (9.0.4) and 10g Release 2 (10.1.2) Applications".
When you upgrade from 10g (9.0.4) or 10g Release 2 (10.1.2) to 10g Release 3 (10.1.3.1.0), no changes are made to your existing installations. Instead, you install and configure new 10g Release 3 (10.1.3.1.0) Oracle homes and redeploy your applications in the new environment.
As a result, there is no need to perform special upgrade-specific backups or to shut down your existing environment during the upgrade process. Instead, you can perform the upgrade procedures independently from the existing installations. Simply maintain your existing schedule of regular backups and maintenance for your current environment until you have cutover completely to the new 10g Release 3 (10.1.3.1.0) environment.
You can (and should) perform the upgrade operations on a separate host. After the upgrade is complete and you have verified that the redeployed applications are working successfully, you can then switch over and begin using the new 10g Release 3 (10.1.3.1.0) installations at a convenient time.
Note, however, if your applications depend upon a database or other backend components, such as an LDAP directory, you must take care to be sure that no data is lost during the transition to the new 10g Release 3 (10.1.3.1.0) environment.
Similarly, any state replication of applications across 10g (9.0.4) or 10g Release 2 (10.1.2) OracleAS Clusters will be lost during the switchover to 10g Release 3 (10.1.3.1.0). For more information on state replication and application clustering in 10g Release 3 (10.1.3.1.0), refer to the Oracle Containers for J2EE Configuration and Administration Guide.
To learn more about Oracle Application Server 10g Release 3 (10.1.3.1.0), take advantage of the following documentation resources. For example, consider reviewing the 10g Release 3 (10.1.3.1.0) books in the following order:
Review the Oracle Application Server Installation Guide for your platform.
In particular, review Section 1.3, "Recommended Topologies," which describes common configurations to consider when installing 10g Release 3 (10.1.3.1.0).
Review the Oracle Application Server Enterprise Deployment Guide, which provides a detailed example of using 10g Release 3 (10.1.3.1.0) as the middle tier in an enterprise-wide deployment of Oracle Application Server.
Refer to the Oracle Application Server Administrator's Guide for information about the tools and procedures you can use to manage your 10g Release 3 (10.1.3.1.0) environment.
Refer to the Oracle Containers for J2EE Configuration and Administration Guide for general information about managing OC4J 10g Release 3 (10.1.3.1.0) instances.
