Checking on Oracle Fusion Applications

Sun Blogger Vijay Tatkar wrote in his blog about the eight technology innovations mentioned by Larry Ellision during his Oracle Open World Keynote speech during last week. Nearly half of them were Sun Hardware related (such as Exadata, ExaLogicSun ultraSPARC t3 etc). Here is the list:

1. Fusion Apps
2. Unbreakable Linux Kernel
3. Solaris Express 11
4. unltraSPARC t3 chip
5. mySQL 5.5
6. exadata
7. exalogic
8. Java 7 and 8

Since the beginning, I am always interested to know more about Fusion Apps, mainly out of curiosity. Oracle Fusion Applications were formally introduced during the Oracle Open World last week (during Open World 2010). As per Oracle Release, this was one of the major innovation or next big thing for Oracle. As you are aware, Fusion Middleware Products were released already. Now, it is time to talk about the Fusion Applications.
You may be already aware; I started my IT career as a Web Developer in a small web hosting company. I used to write perl CGI code and hosting them on Linux Servers running with Apache Web Server and mySQL Database. I got bored (or I wanted a change, I am not sure!) with that job and then moved into the Unix System Administration. I worked as a Sun Solaris Admin and HP Unix Admin for some time. Then I worked in both Peoplesoft System Administration for nearly 7 years and currently working in an Oracle Identity Management (which is part of Oracle Fusion Middleware products) project for nearly past one year.
So, the question is “now what?” And how can we develop the knowledge for Fusion Apps Administration.
I am not sure when Fusion Apps will be deployed full-fledged instead of the other ERP Applications like Peoplesoft. I don’t think it will be near soon, but may be after few years, Oracle may buy in customers who are going to do a new implementation of some ERP Applications.
You know what, Fusion middleware for Fusion Apps is like PeopleTools for Peoplesoft Applications. PeopleTools Technology is the abstract layer on top of which all the Peoplesoft Applications run on. PeopleTools was originally built on C and C++ and finally evolved into a Java Technology. However I still feel some of them are C++ code. While Fusion Middleware is more Java and J2EE apps, I believe Fusion Apps will be more J2EE apps than Peoplesoft. I need to spend little bit more time on implementing a Fusion Middleware and an application. As of now, I only worked on Identity Management Product Sure and little but of Oracle Portal Technologies.
For an IT Infrastructure Administrator like me (who mainly works on Oracle Server Technologies), I think understanding the Fusion Middleware Stack will be important.
Talk to you later. Until then

Informatica Power Center performance – Concurrent Workflow Execution

What is concurrent work flow?
A concurrent workflow is a workflow that can run as multiple instances concurrently.

What is workflow instance?
A workflow instance is a representation of a workflow.

How to configure concurrent workflow?

1) Allow concurrent workflows with the same instance name:
Configure one workflow instance to run multiple times concurrently. Each instance has the same source, target, and variables parameters.
Eg: Create a workflow that reads data from a message queue that determines the source data and targets. You can run the instance multiple times concurrently and pass different connection parameters to the workflow instances from the message queue.

2) Configure unique workflow instances to run concurrently:
Define each workflow instance name and configure a workflow parameter file for the instance. You can define different sources, targets, and variables in the parameter file.
Eg: Configure workflow instances to run a workflow with different sources and targets. For example, your organization receives sales data from three divisions. You create a workflow that reads the sales data and writes it to the database. You configure three instances of the workflow. Each instance has a different workflow parameter file that defines which sales file to process. You can run all instances of the workflow concurrently.

How concurrent workflow Works?
A concurrent workflow group’s logical sessions and tasks together, like a sequential workflow, but runs all the tasks at one time.
Advantages of Concurrent workflow?
This can reduce the load times into the warehouse, taking advantage of hardware platforms’ Symmetric Multi-Processing (SMP) architecture.
LOAD SCENARIO:
Source table records count:  150,622,276
