TechTip: C# for RPGers: Not All Strings Are Born Equal

This time around, I’ll explain a very important object-oriented (OO) concept and some neat things you can do with a string in C# using a new type of object: StringBuilder.

rafael victoria preiraWritten by Rafael Victória-Pereira

If you haven’t read the last couple of TechTips, here’s what I’ve talked about: I introduced strings as a slightly different data type (a complex one, when compared to the simple data type presented before) and showed how to extract characters from it using a method called “substring.” Substring is very similar to an RPG BIF, but it’s a part of the string object, not a standalone function. Strings are objects and have “internal BIFs,” called “methods.” Some are similar to the RPG BIFs you know; others are something totally different.

TechTip: DB2 11 for z/OS Performance and Tuning Tips

Raise or lower the priority of a workload as needed to meet user-specified goals.

susan lawsonWritten by Susan Lawson

This article is an excerpt from chapter 6, “Performance and Tuning,” of DB2 11 for z/OS Database Administration: Certification Study Guide (Exam 312).

 

Using z/OS Workload Manager (WLM), you can set z/OS performance options for DB2. With WLM, you define performance goals and assign a business importance to each goal. The goals for work are defined in business terms, and the system decides how much resource, such as CPU and storage, to give to the work to meet its goal.

 

WLM controls the dispatching priority based on the user-supplied goals. It raises or lowers the priority as needed to meet the specified goal. Thus, you need not fine-tune the exact priorities of every piece of work in the system and can focus instead on business objectives.

TechTip: Discovering Bluemix

The fastest way to discover Bluemix is to sign up for a free trial and start using it.

Ashok IyengarWritten by Ashok K. Iyengar

Editor’s note: This article is an excerpt from the book IBM Cloud Platform Primer.

 

Bluemix is IBM’s enterprise-grade cloud development and deployment platform—in other words, Platform as a Service (PaaS). It is hosted on SoftLayer, which is IBM’s Infrastructure as a Service (IaaS). What makes Bluemix “open” is the fact that it’s built on top of and is an extension of the Cloud Foundry open-source development and deployment cloud platform. Combining the strength of IBM’s software with third-party technologies while using Cloud Foundry to keep it open, Bluemix offers an integrated development experience in the cloud. It helps both born-on-the-cloud and enterprise developers build applications with their choice of tools and languages. Bluemix features cloud integration services that enable a secure connection between an organization’s public apps and its private assets.

5 Practical Ways to Use the Audit Journal to Solve your Administration Woes

The IBM i Audit Journal contains a wealth of information yet remains a mystery to those who can use it most. Carol describes practical ways that security and system administrators can use this information to help them in their daily jobs.

carol woodburyWritten by Carol Woodbury

The past few weeks, I’ve found myself helping our clients solve their issues by looking for specific entries in the audit journal. Most administrators think that the IBM i audit journal is only good for compliance reporting or just used during a forensic investigation. Nothing can be further from the truth. So I thought I’d share a few examples of how you can use the audit journal to solve daily problems. Or to help you debug problems or investigate administration-related issues.

SQL 101: Date-Related Functions, Part 3 - Extracting Information from Dates

This article continues the date-related functions discussion, introducing a few more simple but extremely useful SQL functions: DAYOFWEEK, WEEK, QUARTER, DAYOFYEAR, and MIDNIGHT_SECONDS. Do you have time for some date fun?

rafael victoria preiraWritten by Rafael Victória-Pereira

Let me start with a quick flashback: an RPG Academy TechTip published in October 2015, explaining how to create an RPG function to calculate the day of the week of a given date stirred things up quite a bit. Some readers complained this kind of function was totally unnecessary, because SQL is better equipped to do this type of thing and so on. My reply was that I’d get to a point in the SQL 101 series in which I’d cover the “SQL version” of that particular function, named Clc_DayOfWeek.
