TechTip: Java-Based Client Access for the IBM i

Finally, a decent client is available from IBM for non-Windows platforms!

barry klineWritten by Barry L. Kline

In my recent article "Is IBM i Access for Linux Right for Your Shop?", I reviewed IBM's Linux offering for accessing the IBM i's database and for providing 5250 emulation. The executive summary of that article is simply, "It's great for ODBC connectivity, but the emulator is best replaced by one of the open-source emulators or commercial alternatives." Shortly after the article was published, I received two emails from readers (Thanks to both Bobs!) recommending that I give IBM's Java-based offering a try.

TechTip: Virtualization Made Simple with i-hosting-i

Virtualizing has never been easier!

What is i-hosting-i? As the name implies, the i-hosting-i technology is simply an environment where an IBM i partition virtualizes resources for another IBM i partition. The hosting partition is often referred to as the host or server partition, and the hosted partition is typically known as the client partition. The client partition utilizes virtual resources from the host partition and typically has no physical hardware directly assigned to it. The host partition can virtualize the following hardware for the client: disk, tape, optical media, and networking. The client can have a mixture of virtual and physical hardware assigned to it (i.e., the client does not have to be a pure virtual image).

TechTip: Map Your Network Drives to the IBM i

Use the IFS and NetServer to safely and securely provide file access to users.

The IBM i is an extremely reliable system that is an excellent resource for your company's most crucial information. Many PC-centric applications use critical files that may be stored locally on the client's hard drive. When proper backups are neglected and the client's hard drive fails, you may be left with disastrous results. What better way to provide the most reliable support, backup, and accessibility than to store files on and access files from the IBM i? IBM supports this capability with the IFS in collaboration with NetServer.

TechTip: Implementing an Internal Instant Messaging System

Building an intranet instant messaging system for only company use is easily accomplished with two open-source projects: Openfire and Spark.

Everyone should be familiar with the numerous instant messaging (IM) systems circling the Internet today. The clients that usually come to mind are

Some time ago, I was given the task of implementing a messaging system on my employer's intranet. Since many computer viruses, malware, and spyware programs are viciously spread across many of the commonly used chat clients, my IT department decided to limit this security threat by going with something that could be easily built solely for internal use. After much testing and consideration, Openfire and Spark were deployed.

MSN Messenger, AIM, ICQ, Yahoo, and IRC, to name only a few. All of these clients are great for communicating with friends, family, and anyone you want to talk to remotely, but they typically involve going outside an internal network, which can cause security concerns.
