Three Tier Configuration

Question

Hi friends,
I am planning to implement oracle three tier architecture and want to know -
How the oracle three tier architecture should be configured on a network?
As per my information :
Database Tier : Oracle 9i server database on a machine
Middle Tier : oracle 9i AS as middle tier on a machine
Client Tier : what software should be installed on client tier?
As middle tier need
Pentium 300MHz,6GB hdd space,512 RAM
What are the minimum requirement of client tier to run form and reports applications?

Answer 1

1. Use 10g Application Server - You have to install the Enterprise version for forms & reports servers - you can choose to not configure the pieces you don't want to use as part of the setup though.
2. Java plugin is more mature than the jinitiator. Java plugin works on more systems and is much quicker since its much newer than the 1.1.8 and 1.3.x version oracle provides - Sun or IBM jvm's work great.
3. In most cases uses have an office application, email application or other tools running in conjunction to being logged into a forms/reports application. With the over head of multiple browsers, jvm, and other applications i wouldn't recommend anything else. With Pentium 4 systems fully loaded for business systems running 699.00 or less (dell/hp/gateway) i don't think client side computing power should be an issues - especially if you can afford the licensing costs of the application server to begin with :)
In my experience give your "power" users (the ones running your business apps) the POWER they need to get the job done right and they will appreciate the new systems you implement rather than fear them. A PC upgrade is alot easier then months and months of headaches with people complaining about response times, load times, performance and application useability.
