TechTip: IFS Containers Part 2, Automation with IBM i Chroot

Automation wins in the end. IFS Containers have automation as a first class citizen.

Written by Aaron Bartell

In the first article of this series, I discussed what IFS Containers are and how they use the chroot command to implement the container concept. To create the IFS Container, we had to manually create directories and copy files. That wasn't a big deal for the small example we created, but imagine if you needed to create an IFS Container for an entire PASE application that had requirements for hundreds of directories, commands, and libraries. This is where automation becomes a necessity, and more specifically, the IBM i Chroot open-source project.

RPG Fundamentals Tip #3: Working with Nomain Modules

Unlike cycle main and linear main programs, nomain modules have no main procedure.

Written by Bryan Meyers and Jim Buck

Editor’s note: This article is excerpted from Programming in ILE RPG, Fifth Edition, chapter 14, “Building Modular Programs with Procedures.”

The programs previously discussed [cycle main and linear main] are complete programs in themselves. They include a main procedure, along with all the other required subprocedures, coded within one source member, or compile unit. ILE also enhances modular programming concepts by allowing you to code a source member that consists of a segment of a program without a main procedure. The resulting Nomain module contains only subprocedures (one or more) that you can combine with other modules to create a program. By itself, a Nomain module cannot create a program object. One of the modules in a program must have a main procedure.

Mobile Computing and the IBM i

Mobile computing is rapidly maturing into a solid platform for delivering enterprise applications. Many IBM i shops today are realizing that integrating their IBM i with mobile applications is the fast path to improved business workflows, better customer relations, and more responsive business reporting. The ROI that mobile applications can produce for your business is substantial.

This ASNA whitepaper takes a look at mobile computing for the IBM i. It discusses the different ways mobile applications may be used within the enterprise and how ASNA products solve the challenges mobile presents. It also presents the case that you already have the mobile programming team your projects need: that team is your existing RPG development team!
