TechTip: New Function Resolution Casting Rules for DB2

They may be obscure, but they're definitely not to be overlooked.

kent milligan 117x117Written by Kent Milligan

My recent article on the DB2 for i 7.2 release highlighted some of the more noteworthy database enhancements in the latest IBM i release. There wasn't room in the previous article to discuss all of the DB2 enhancements, so in this article you'll learn about a smaller DB2 improvement known as function resolution casting rules.

TechTip: Suggestions for DB2 for i Code Quality Testing

Prepare to put your DB2 SQL code "through the ringer" to ensure it's ready for prime time.

Written by Michael Sansoterra

Typically, developers love writing new code. And while an application is new and business rules are fresh in the mind, it's generally pleasurable to enhance code as change requests meander in. But after the years roll on, and business requirements are forgotten, and complex code looks unfamiliar, then maintaining the code can get downright ugly. How does one know an obscure business rule wasn't violated when changing code?   It's usually not until code has been moved into production that the misery starts after a bug rears its ugly head.

In the Wheelhouse: The Little POWER8 That Could...Almost

When apps attack, memory is the weakest link.

steve pitcherWritten by Steve Pitcher

IBM announced the new 4-core POWER8 S814 on June 10. While the new P05 iron works well for many shops, I think a lot of customers could benefit from added memory capabilities if IBM were able to do it.

 

Back when IBM announced the first round of POWER8 boxes in April, a number of people were wondering where the true SMB box was. By SMB, I mean in the P05 software tier. Most of the IBM i on Power Systems market is around the P05 size, small machines with a couple of cores running the small side of the small-to-medium businesses. Those are the IBM i bread and butter customers right there.

Practical RPG: Using Data Queues, Part 1

This article moves past the basics of data queues to the practical application of these lightweight communication marvels.

joe plutaWritten by Joe Pluta

In previous articles on data queues and on keyed data queues, I presented the basics of how to create them and how to program for them. I went into some detail about the commands used to manage data queues and the RPG code required to access them. In these next articles, I'm going to go a slightly different direction and present you with the actual business case for using data queues in a robust multi-user (and even multi-platform) architecture.
