IBM’s DB2 Query Management Facility (QMF) has been a stable, perpetually reliable workhorse for DB2 query and reporting for many years. However, as other Business Intelligence (BI) technologies evolved, QMF has taken a back seat to some newer trends in BI, such as sophisticated dashboards, Online Analytical Processing (OLAP) support, graphical reports and more, which have become the standards by which BI tools are evaluated. IBM’s release of QMF Version 10, however, is a game-changer.

This article examines many new features available to new and existing QMF customers. The core product has been enhanced…

Z990 NEWS

The new eserver zSeries 990 (z990) (103-142) comes in four models: A08, B16, C24, and D32. The two digits in the model number indicate the maximum number of processors; multiply that number by 8GB and you have the maximum memory size; multiply that number by 1.5 and you have the number of Self-Timed Interconnect (STI) host buses. The minimum for all models is one processor and 8GB. The processors are based on CMOS9S-SOI technology, and are 50 percent faster according to IBM’s Internal Throughput Rate Ratios (ITRRs). New maximums are 30 LPARs (double…

IBM recently announced a new software licensing metric called Midrange Workload License Charges (MWLC), which is available exclusively for z/VSE Version 4 users running on IBM System z9 servers. It’s the latest in a series of software licensing options announced in conjunction with new mainframe servers to help reduce IBM software licensing costs. MWLC provides a sub-capacity pricing option that was previously available only with other licensing methods for z/OS customers. This article provides a perspective on this new announcement and how it might benefit VSE customers.

Assume you’ve been given a directive by IT management to “tune” things. What strategies are available and how do you judge which ones are best? Considering the current economic climate, can any be implemented on a shoestring budget? Can any of these tasks be assigned to resources with basic DBA skills and still be productively accomplished?

A few of the many strategies for approaching and overseeing tuning efforts include:

• Tune from top to bottom. Tune z/OS (i.e., memory, dispatching priorities, WLM environment), then the DB2 subsystem, database objects …

Does this IT challenge sound familiar? Your data center consists of a complex maze of applications and systems spread across multiple platforms—isolated islands of data spanning Unix, Linux, Windows, and the mainframe. When your people need to query and act on mission-critical data, finding the information they need in the form they need often becomes a tedious, costly, and morale-sapping process.

If your enterprise suffers from data center challenges such as these, SmartIS® from SEGUS Inc. offers a comprehensive information management solution that streamlines operations and makes it easy to access and act on…

Recently, I’ve noticed a couple of strong indicators that the message is getting out about the favorable cost and resilience of the mainframe platform.

One of these indicators is a report on the Mainframe Blog by Jim Marshall, discussing the cost-effectiveness of his zLinux implementation in the defense sector. Capt. Marshall has been running Linux under zVM with 45 virtual servers in three LPARs, covering production applications, testing, and development. Following an IT financial conference, he decided to compare the cost of his mainframe Linux installation with a comparable Intel setup. His conclusion, when factoring in…

My previous article on packages (z/Journal, February/ March 2006) provided what one might consider an introduction or refresher. However, how to create packages and how some aspects of a package work are just a small part of the picture. A package is the DB2 process that lets you get to your data. Understanding how your choice of parameters can impact a package’s behavior is important. 

This article takes an in-depth look at packages and discusses how some of the different bind keywords affect a package’s behavior, the use of packages by triggers,…
