For example, whereas you might require triggers for day-to-day SQL operations, you might not want those triggers to be fired when you run particular scripts. The standard practice is to drop a trigger and recreate it when it is needed again, but you may find this a bit disconcerting if you have to keep track of lots of triggers. (Now, where did I keep the source code for those triggers?)

  • Level: Intermediate
  • Date: May 2008
  • Common problems in J2EE applications that access databases occur around end-to-end authentication and authorization, as well as the end-to-end audit path. The concepts of data sources and connection pools provide many advantages, but they can also lead to security breaches. This vulnerability happens because, after the security layer of the application server has been passed, all requests are usually mapped to one common user ID to access the database. A new feature called trusted context, available in DB2® 9.5, allows users to leverage the benefits of connection pooling without sacrificing security. This tutorial describes how you can use that feature with a Data Web Services Web application.

  • The annotated XML schema decomposition feature introduced in DB2® 9, can be used to decompose entire, or fragments of, XML documents into relational tables. DB2 9 XML shredding technology uses annotations in XML schema as the mapping language to map information in an XML document to relational tables. The DB2 XML decomposition uses annotated XML schema to obtain mapping information. Annotations added to the XML schema do not participate in the validation of XML documents. Therefore, you can use the same XML schema for both mapping and the validation of XML documents. In this article, you'll find detailed examples of how to use DB2 Visual Studio 2005 Add-ins to build an application that use DB2 9's XML shredding technology, which allows XML to be shredded, stored, and validated into a relational table.

  • This article describes a communication implementation between two database sessions using message pipes. Both alerts and pipes can function in either asynchronous or synchronous mode. Using pipes, you can actually transfer a packet of messages, which consist of different data types, from one session to another. This implementation is very useful if you are migrating your application from Oracle to DB2 Universal Database.

  • This powerful open-source language lets you take full command of DB2. Scripting languages hold a big advantage over traditional programming languages (such as C++, Java, and COBOL): They make developers more productive. Each line of code in a scripting language typically does more than a line of code in a traditional programming language.
