Use the Gripping Charm to grasp the possibilities that lie ahead. Read how Scott dodges danger and dementors with DB2 for i spells.

Written by Scott Forstie

Good, you’re back. I was beginning to think that you had encountered some ugly business. After all, there is danger at every turn. For myself, I have been keeping a very public profile since we last spoke to one another. With the rollout of IBM i 7.3, everyone wants to know “What’s New in DB2 for i.” As I do my level best to tell them about the DB2 for i enhancements, I notice that frequently people aren’t fully utilizing the capabilities already at their fingertips. As you’ll read in this episode, an established DB2 for i column-level control will rescue me from an untimely demise.

TechTip: Data Warehouse Updates from IBM i Using SSIS PDF Print E-mail
Tips & Techniques - Database

Point-and-click your way to repeatable data updates to or from any database from your DB2 database.

tom snyderWritten by Tom Snyder

One common theme I’ve experienced through several RPG developer jobs is to provide data to an external data warehouse from the all-knowing DB2 database. Other common needs may be to supply member information to a website or to some third-party software. Sometimes these would be DB2 databases, and sometimes they wouldn't. I'm going to show you how to quickly set up a SQL Server Integration Services (SSIS) package to take care of this process for you.

Traveling back in time is easy and can answer important questions. Take the next step with Scott on this journey through the castle.

Written by Scott Forstie

Glad you could join me for episode two of this series. When I last talked to you, I had just learned what house the Sorting Hat had chosen for me. In an unexpected turn of events, I am bound for the house of Slytherin. Unlike some before me, I don’t resist the decision, bowing to the wisdom of the enchanted hat. Perhaps I’m comforted by the knowledge that my path will be influenced by future decisions that I can control.

 

My housemates welcome me with open arms and wary looks. After some time has passed, I have settled into a routine of training and competition. I am intrigued by the possibilities that lie before me. Much like my life here in the castle, DB2 for i on IBM i 7.3 provides similar opportunities for new adventures.

Here’s a reusable reference for connecting your SSIS to your IBM and Microsoft databases.

tom snyderWritten by Tom Snyder

I’ve been introducing the Microsoft SSIS technologies to the IBM community, who is showing interest, and I would like to continue providing more. Modular programming is always a good thing, so I’m going to try to reduce the initial data source configuration overhead in my articles by creating this reusable, modular article that is the starting point for any SSIS packages using databases.
