DB2 9 for z/OS: Deploying SOA Solutions

Abstract

Flexibility in business has become of equal in importance with operational efficiency. Service-oriented architecture (SOA) can help businesses respond more quickly and cost-effectively to the changing market conditions by promoting reuse and interconnection of existing IT assets rather than time-consuming and costly reinvention.

SOA has been the top fashionable topic in IT for a few years now, which is because there is a consensus of opinions among enterprise architects that SOA is the key to making the IT department a catalyst for growth and innovation.

DB2® for z/OS® integrates with Web services, acts as a service provider, and lets SQL applications consume Web services. DB2 customers can make their heritage DB2 applications easily available in a service-oriented architecture and by supporting native XML data types. Using DB2 you can build new applications and exploit the strategic characteristics that XML provides.

In this IBM® Redbooks® publication, we help you to get started with SOA by showing the implementation of the minimum requirements: Creating Web services that allow access to data that is stored in data servers or applications and the realization of interaction services for business to consumer integration. We implement these requirements using functions that DB2 for z/OS provides, such as pureXML™ and SOAP UDFs, in conjunction with the functions that Data Studio, DataPower® , and WebSphere® Application Server provide.

The ThinkPad Models

The ThinkPad Models

There are several ThinkPad models, each of which has a slightly different architecture. Several of the models are not suited for running Linux. The ones you are most likely to meet are:

ThinkPad 340

Monochrome-only machine with a 486SLC processor clocked at 50 MHz (i.e., non-Intel). It comes with disks of 200-360 Mb capacity, depending on the precise model. David N Turner reports a successful installation of Slackware 2.3.0 on a 340CSE with 12 Mb memory and 200 Mb hard disk. He also warns us that it has the same floppy disk change problem as the 750 series machines (see below). Specifying

ramdisk floppy=thinkpad

at the bootdisk prompt gets around the problem.

Ps/Note E35

Jerome Kaidor reports that he has made Linux 1.2.0 run on his Ps/Note E35, which he thinks is essentially a ThinkPad 350 (whatever that may be) without PCMCIA slots. He managed to squeeze everything he needed into 21 Mb, even with X installed!

ThinkPad 360

This model has options based around the 486DX2 at 50 MHz. There are disk options between 340 and 810 Mb, and dual-scan colour and active-matrix colour screens. The "mouse" is IBM's Trackpoint device, located amongst the G, H and B keys. Linux is happy on this model (reported by Richard Soderberg, for example).
