I've talked about the subject of long lived TCP connections and load balancers for years, explaining to people why they may not need or want to use a load balancer between two servers. Each time I explain it I remind myself that I should probably write it down so I can just point to the URL. So today is the day that I write it down for you. Before we get into the guts of this we should start by defining a couple of terms: By long-lived connection I mean TCP connections that...

How to Configure and Test Whole Server Migration Network Components Introduction Here’s a cold, hard truth for sysadmins: in enterprise computing environments, no matter how stable or how large or how fast or how powerful the hardware or network, the probability that a hardware failure or a network glitch will occur can never get to zero percent. The guaranteed-never-to-fail enterprise computing environment has not been invented yet. One strategy for making systems as...

Introduction This document will outline the Best Practice approach for Instantiating a DB2 target database from a DB2 or other database source system. Main Article One of the biggest challenges in creating a DB2 target database for replication is to insure that no collisions or data loss will occur when applying the change data after the initial instantiation of the target database. Oracle GoldenGate has addressed this issue by including functionality to apply the change data...

Introduction In Fusion Applications, users are not directly assigned access to individual functions and data. Instead, access is provided through roles. Roles group users for a specific purpose and define their access privileges. During the provisioning and installation of Fusion Application, a Super User (FAADMIN, by default) is setup with the following roles, to administer the underlying technical stack (Fusion Middleware) and to act as a Functional Setup Manager....

Introduction There is a lot of confusion about how to use JSF component binding in managed beans in a clustered environment to meet high availability. In this post we will highlight important considerations. Main Article A very common mistake is to bind a JSF UI Component to a managed bean which is in a scope greater than requestScope or backingBeanScope. You should not do this for two reasons: UI Components are not serializable, so your application might fail to work...

Introduction Over a year ago I wrote a couple important posts about the domain architectures used in Oracle Identity Management deployments. You can find these posts here and here. These posts have been very popular. I’ve received lots of positive feedback on them but also a fair number of questions. So, I thought that it would be worth revisiting the topic now. Main Article Let’s Review My First Post So, the central premise of my first post was that it is a good idea to...

What is it? At the Oracle Open World 2011 conference, I presented a session titled "Enterprise-class SOA on Exalogic" along with Vikas Anand and Manas Deb. Exalogic is part of Oracle's new breed of engineered systems, and is geared towards the middleware space. For those new to the term, an 'engineered system' is one where a single vendor provides everything from hardware, network, OS, middleware, applications, etc in one appliance. The hardware and software are fully...
