Actions speak louder than words.  So if you want to be appreciated as a DBA, save your company big bucks and CPU resources.
These days it seems everyone is running out of CPU capacity on their UNIX machines and on the mainframe. With pureQuery you can provide a way to help your company save real [...]]]></description>

  By David Beulke
 
Another situation when a transaction runs into problems is when it must check something outside of the critical transaction path or its normal activity. For example, when a transaction uses seven different discrete web services to accomplish a complete transaction unit-of-work and after the third [...]]]></description>

		<description><![CDATA[DB2 Java Performance Standalone Transactions Part 1
By David Beulke
 
In previous blog entries I have talked about transaction scope, how Java applications access the database too much and transaction units of work (UOWs) are not really analyzed properly.


 
Too often these days the design and development are done in an Agile or SCRUM type of [...]]]></description>

		<description><![CDATA[Java performance is often a problem because the application processing is emulating the database which executes more efficiently or the processing is poorly designed. Either of these scenarios that my teams have found during performance or design reviews always led to extended I/O activities and excessive CPU usage. 
Too often, when the application was designed, [...]]]></description>

		<description><![CDATA[Designing the Unit-of-Work for a given transaction entails many components.  Different techniques and methods are incorporated depending on the components such as Hibernate, iBatis, JPA or Enterprise Bean technology to process the transaction.  The Java transaction framework and the object patterns incorporated with the components also affect the transaction unit-of-work. All these factors together provide complete [...]]]></description>

		<description><![CDATA[Control Java Application References to the Database
One of the first standards and principles neglected in the Java applications that I have seen is that the application references the database too many times to complete a single transaction. While it is good to use your ORM database interface, the architect and application programmer should know how [...]]]></description>

		<description><![CDATA[Given the object model of Java and the relational model of the database, accessing data properly continues to be difficult for most Java application developers. Over the history of Java development, there have been many attempts within vendor products, interfaces and open source projects to bridge this object to relational data chasm. Many object to [...]]]></description>

The problem is the poor performance lessons experienced from the application implementation are not fully understood and the performance problems are continued and replicated into the next architecture, framework or pattern.

When getting my taxes ready every year, I review the previous year’s activity. Reviewing 2008 has shown that the majority of my consulting was spent fixing and tuning Java based DB2 systems. This is not a big surprise since the trend and majority of my clients over the last three years have had Java performance [...]]]></description>
