IBM Navigator for i adds a new bird’s-eye-view performance interface in IBM i 7.3.

steve pitcherWritten by Steve Pitcher

When talking about IBM i, it’s often stated that it’s the most securable operating system available, not necessarily the most secure. While IBM gives you the tools to ensure your system is secure, the human element must be considered. This is why it’s securable. Each operating system depends entirely on the system administrator to ensure doors are locked and windows are shut. This fact is true about many other aspects of the IBM i operating system, including performance. A system will perform as well as it’s configured to.

TechTip: An Easier Way to Search Through Massive Job Logs PDF Print E-mail

Cilasoft offers its new Job Log Explorer tool to the IBM i community at no cost.

guy marmoratWritten by Guy Marmorat

Anyone who has searched through mountains of pages in job logs to find specific program messages during the process of troubleshooting knows all too well how time-consuming and tedious this task can be. In fact, as my team and I have worked with customers and partners over the years, we’ve commonly heard complaints about this very thing. But what’s surprising is there hasn’t been a useful tool available (at least that we could find) to help quickly isolate critical job information in these ungainly job logs. It’s basically a process of repeatedly pressing the F16 (Shift+F4) search key while trying various search terms.

Integrated File System support leads the way with this important new update.

steve pitcherWritten by Steve Pitcher

As of today, there’s a new version of the highly popular IBM i Access Client Solutions (ACS) product. If you’ve already downloaded the April version of ACS, you can easily upgrade using the new Check for Updates feature underneath the Help option in the title bar. Otherwise, click here and download the latest version. If you want all the ODBC features, those are included in two separate Application Package downloads (one for Windows, one for Linux) found on the IBM ESS website.

TechTip: Which Server Job Is Mine? PDF Print E-mail

A client application sometimes "freezes" or begins responding very slowly. You may need to look at the IBM i side of the application. But can you can find it? This tip helps you track down the IBM i server job.

sam lennonWritten by Sam Lennon

For the purposes of this discussion, a client application is a "program" that isn't running on the IBM i host, but is connecting to it using JDBC, or ODBC, or JT/400, or FTP, or TCP/IP, or some other communications technique. A client application might be the Rational Developer for i (RDi) IDE. It might be one of the free SQL clients like SQuirreL or SQL Workbench/J. It might be an FTP client. It might be a .NET application. Or something else entirely.

Partner TechTip: VIOS Is Set and Forget. Isn't It? PDF Print E-mail
Tips & Techniques - System Administration

It's good practice to build redundancy into your VIOS configuration so that client LPARs can use multiple VIOS, but how would you know if one—or both—had failed?

ashley giddingsWritten by Ash Giddings

There's a popular misconception in the industry that Virtual I/O Server (VIOS) is just a slimmed down version of AIX. If you come from an AIX background, you will find the command line interface (CLI) to be much more familiar than an IBM i administrator would, for example, but the similarities stop there.

Partner TechTip: Finding Hidden IFS Error Logs PDF Print E-mail
Tips & Techniques - System Administration

Friday, 11 September 2015 00:00

Does your team manually open IFS error logs for your application? If you run EnterpriseOne, SAP, Domino, WebSphere MQ, or M3, it's time to automate.

tom huntingtonWritten by Tom Huntington

Traditionally, IBM applications were written only for IBM i, sending all their error messages to QSYSOPR. However, UNIX-based applications have been migrating to IBM for the last 15 years or so. These applications may have some errors—such as a file full message— that go directly to IBM i QSYSOPR, but it's likely they also have other errors that are hidden in a log file within a directory on IBM i. How does your team manage these?

When first learning how to use Wireshark, it can be overwhelming. This TechTip has us dissecting a single frame.

lisa bockWritten by Lisa Bock

Editor's note: This article is a follow-on to TechTip: Get Familiar with Wireshark, an Open-Source Packet Analysis Tool.

 

I have spent years immersing myself in packet analysis, and to help you get started, we will examine one single frame in Wireshark. In this example, I have opened a pre-captured trace file shown in Figure 1, where I have requested a webpage. The conversation is between the two endpoints 23.15.7.155 and 192.168.1.102.
