- Powering SOA Solutions with IMS
New application development tools and the IBM® service-oriented architecture capabilities for IMS™ can help your business improve the speed and agility of its development efforts. Both IMS and the IMS SOA Integration Suite support your on demand systems and your distributed IMS application environment.
Powering SOA Solutions with IMS provides background and explanations to clarify the choices and methodologies that are available to modernize your IMS applications and provide access to IMS data stores through non-traditional callers.
- Embedding Informix Dynamic Server: An Introduction
In this IBM Redbooks publication we discuss and describe the capabilities for embedding IDS into applications and software. We introduce the technological architecture, and describe several of the functions and features that support IDS as a robust and powerful embeddable DBMS. Many of these features are unique in the industry today, enabling clients to create a business advantage.
The Informix Dynamic Server can support the requirements of an embeddable DBMS, and is doing so for many companies today. The low administration requirements of IDS enable clients to deploy thousands of IDS instances, embedded in applications in locations where there are no technical resources to support the database. The real requirement is for applications with embedded databases that require little or no administration, take minimum storage resources, have excellent performance, and are highly reliable.
As a mature and reliable DBMS, it works well with small, growing, and large databases, and meets the key requirements for embedded databases. These include the ability to execute without the need for any configuration or other DBA administrative activities, and the flexibility to work on all of the platforms commonly used in the marketplace today.
- DB2 9 for z/OS: Packages Revisited
DB2® packages were introduced with DB2 V2.3 in 1993. During the 15 years that have elapsed, a lot has changed. In particular, there is a more widespread use of distributed computing, Java™ language, new tools, and upgrades in the platform software and hardware. The best practices back then just might not be optimal today. In this IBM® Redbooks® publication, we take a fresh look at bringing packages into the 21st century.
We begin with an overview of packages and explain the advantages of using packages.
Because database request module (DBRM) based plans have been deprecated in DB2 9, you need to convert to packages if you did not use packages already. We provide guidance on using a DB2 provided function to convert from DBRM-based plans to packages.
We re-examine the application development frameworks for packages: program preparation, package setup, and execution. For distributed applications, we include a discussion of a utility to identify and remove deprecated private protocol and converting to DRDA® as well as an introduction to the new pureQuery function of Data Studio. We also discuss common problems and their resolutions.
We then explore administration and operational activities dealing with packages, including security, access path management (where we discuss the newly introduced package stability feature to allow for a seamless fallback), and management and performance aspects.
The appendixes include useful queries and mention tools for managing packages effectively.
