DB2 9 for z/OS offers a number of new performance features. One of the most exciting feature combinations I have found in DB2 9 and purequery is the ability to convert dynamic JDBC SQL applications into static transactions. This combination uses the new IBM Data Server Driver for JDBC to eliminate the overhead of each JDBC SQL transaction in the context of dynamic JDBC security authorization, object validat

For example, in Windows, the line separator is a normal line break. In Linux and other operating systems, although it is also a line break, the line breaks are different on the two operating systems. If you open the ASCII file created on a Windows operating system on a

Over the past few years, many books have been produced to discuss best practices in DB2 design and implementation, including a large number of books and articles. These books delve into how to design DB2 and integrate it into an application. To provide some basic guidance for customers and business partners to understand, this article compiles a series of best practices to consider when using ibm®
