Deployment Guide for Oracle Application Server
Introduc
ti
on
This deployment guide contains con
fi
guration procedures for AX Series server load balancers to support
Oracle Application Server.
Oracle Application Server is an integrated, standards-based software platform consisting of Oracle HTTP
Server and OC4J (OracleAS Containers for J2EE), which deploys J2EE-based applications. Oracle
Application Server Enterprise Edition is an application platform suite (APS) that offers a comprehensive
solution for developing, integrating, and deploying all of your enterprise’s applications, portals, and Web
sites. Enterprise Edition combines robust business integration, leading J2EE performance, capabilities
for enterprise portal, real-time business activity monitoring, business intelligence, identity management,
and wireless deployment.
For more information on Oracle Application Server Products visit:
http://www.oracle.com/appserver/enterprise_edition.html
The AX Series with its Advanced Core Operating System (ACOS) has been designed speci
fi
cally for ap-
plications such as Oracle Application Server providing better robustness in failover situations, intelligent
load sharing and of
fl
oading security processing.
This guide used the AX Series 2.0.1 in routed mode and Oracle Application Server 11g.
Prerequisites & Assump
ti
ons
A10’s AX platform should be running software version 2.0 or later.
•
It is assumed that users have some basic con
fi
guration familiarity with both AX and Oracle Ap-
•
plication Server products.
The Oracle Application Server products used in this deployment guide are Oracle Web Server,
•
Identity Manager and Single Sign-on. As the applications are accessed by users through the
Oracle Web Server, the deployment con
fi
guration below is for the Oracle Web Server.
The AX can be con
fi
gured in one armed mode or routed mode.

Auto-Port Transla
ti
on
The AX device allows you to use different port numbers for a real server port and its corresponding
virtual server port. The AX auto-port translation feature can automatically translate the port numbers
internally. In this example our VIP address 192.168.215.63:443 is bound with real server (192.168.216.60)
port 7777, the default port for Oracle HTTP Server. The AX device translates the VIP address into the
real server IP address, and translates the virtual service port number into the real service port number, to
interact with the real server on the client’s behalf.
Note
:
For standard port numbers (port numbers 0-1023), no additional confi guration is required for auto-
port translation. For example, if the VIP service port number is 80 and the real port number is 542, no
additional confi guration is required.

Con
fi
guring Templates for Oracle Web Server
Templates are sets of con
fi
guration parameters that apply to speci
fi
c service types or to servers and ser-
vice ports. Even though in some cases default templates can be used, it is recommended that you create
templates speci
fi
cally allowing you to change the templates in the future without impacting the default
templates, which others may be sharing also. For this deployment, the following types of templates are
used:
HTTP Template
•
TCP-Proxy Template
•
Client SSL Template

Summary and Conclusion
The con
fi
guration steps described above show how to set up the AX device for Oracle Application
Server. The key advantages for using AX Series in the deployment for Oracle are:
Transparent application load sharing
•
Multiple Oracle Application Web Servers can be pooled together without any changes to how users
◦
access the applications.
Availability
•
Obtain higher availability when Web Servers fail so that there is no direct impact to how users access
◦
the applications.
Performance for users accessing Oracle applications using Web browser
•
Achieve higher connection throughput and faster end user responsiveness by of
fl
oading security
◦
processing to the AX device.
