OIM monitoring check-list

Introduction Systematic monitoring of OIM deployments helps to reduce risk of both technical and security related issues. It also can help to avoid performance degradation that can happen because of data growth over time. This post presents a set of topics about OIM and WebLogic monitoring, and it presents tools that can be used for […]

Using ODI with a Development Topology that Doesn’t Match Production Topology

Introduction The cost of reproducing a production environment for the purpose of developing and testing data integration solutions can be prohibitive. A common approach is to downscale the development environment by grouping databases and applications. The purpose of this post is to explain how to define the ODI Topology when the physical implementation differs between […]

How Many ODI Master Repositories Should We Have?

Introduction A question that often comes up is how many Master Repositories should be created for a proper ODI architecture. The short answer is that this will depend on the network configuration. This article will elaborate on this very simplistic answer and will help define best practices for the architecture of ODI repositories in a […]

Configuring the iPlanet as web tier for Oracle WebCenter Content (UCM)

If you are looking for configure the iPlanet as Web server/proxy to use with
the Oracle WebCenter Content, you probably won’t found an specific documentation
for that or will found some old complex notes related to the old 10gR3.

This post will help you out with few simple steps.

That’s the diagram of the test scenario, considering that you will deploy in
production in an cluster environment.



Change WebLogic Server Mode from Development to Production and JDK Mode from Client to Server

What does it take to change WebLogic 10.3.x server mode from development to production?

You quickly search on the Internet and quickly land to documentation such as here: http://docs.oracle.com/cd/E21764_01/apirefs.1111/e13952/taskhelp/domainconfig/ChangeRuntimeModes.html . The doc says you just need to go to the WebLogic Console to do it. That is easy, right?

But then the next link or so you may found a blog like http://blogs.oracle.com/learnwithpavan/entry/run_weblogic_in_production_mod , which says you need to set some Java parameter to make that happen.

So, which one is right?

Well, the truth of the matter is, to completely change a server from Development to Production Mode, two things need to happen:

  1. From Console -> Domain -> Production mode, check the Production Mode check box. This change will go into config.xml
  2. In setDomainEnv.sh, set PRODUCTION_MODE=true.

You will notice that if you only do #1, the Java will still start with “-client” option. Only when both of these settings are done, the server will start with ‘-server’ in its Java command line.

For differences between Development mode and Production mode, please refer to http://docs.oracle.com/cd/E21764_01/web.1111/e13814/wls_tuning.htm#i1111053 for details.

Using a Web Proxy Server with WebCenter Family

The use of a Web Tier is always recommended in a production environment, for security, performance and better control and load management, no matter if is a Intranet, internet or extranet environment.

The most common use for the Web Tier with WebCenter is acting as Reverse Proxy to forward all requests to a frontend WebCenter site to the application server (Figure A), but there’s to many ways to do an enterprise deployment with a web tier and many flavors of web servers and load balancing options.


Let’s start with the WebLogic plugin with supported webservers. You can found the standard plugins in your WebLogic instalation dir, that will something like “%WEBLOGIC_HOME%/server/plugin/%OS%/”, but I recommend you to download the latest plugin from Oracle’s OTN or eDelivery websites, you will found the Oracle WebLogic Server Web Server Plugins 1.1 or later. With the version 1.1 you will found plugins for Apache 2.2.x (32-Bits and 64-Bits) and for IIS 6+ and IIS 7+. Always confirm the OS support with the WLS Plugin Support Matrix. If you need support for iPlanet 6+ or 7+, you can use the version 1.0. Any throuble to found the files, try search or create to the Oracle support (Ref.: Doc ID 1111903.1).


Some times you do not want to use a separate web server, you can use the WebLogic as a Web Server by using a servlet, but this is subject for another post.

When you are deploying a WebCenter solution using a proxy server, you need to remember to proxy all your requests from all weblogics for Security, performance and Control and also all non-weblogic requests such as static files, WebCenter Content custom requests, Services, Portlets and 3rd Party.

Is common in intranet deployments you see calls direct to the application servers, calls to several different servers, like the Figure C.


Above you can see the same sample with all calls using the web server, for proxy forward, for reverse proxy, static files caching, even the use of Oracle Coherence is easy when you have a WebCenter Spaces + Content deployment.


We cannot forget to talk about the clustering and load balancers, Clustering is easy done by the WebLogic, you just need to follow the documentation. For Load balancing you need to choose what kind and what load balancer you will use.


You can do load balancing using the Web Proxy Server with WLS Plugin or a servlet as mentioned above or a External Load Balancer (Hardware) or Appliance.

Using the WLS Plugin you will need to remember to create a entry for WebCenter Server that are you using, that means that you need to create a entry for the /webcenter/ another for the /cs/, another for the “custom sitestudio” calls, for the portlets (If you do not create a parent folder for the portlets, you will need to create a entry for each portlet) and an entry for any other 3rd calls.

The configuration file for each entry will looks like this sample for IIS7:


# Changed by Oracle A-Team (Adao.Junior)
# Date: 07/31/2011
# WebCenter Content: CUSTOMER_WEB_SERVER
# WLSPlugin1.1-IIS6-IIS7-win64-x64




For a External Load Balancer (Hardware) you have many options, such as the f5 Big-IP, a guide to help you deploy with WebCenter could be found here.


There’s a option to use a hybrid configuration, with Hardware loadbalancers and Web Proxy to handle the web calls between the users and web farms, and web proxies and between the proxies and applications servers.

From Dev to Test to Production

So you have chosen AIA for integrating your enterprise applications due to the many good things it offers such as a canonical data model, a profound reference architecture, and so on. That’s great. And you have started developing a set … Continue reading
