In order to analize system performance I tried to discover how time is spent within my database system.
According to the documentation, TOTAL_RQST_TIME=TOTAL_WAIT_TIME + TOTAL_*_PROC_TIME.
By querying the service class table function (MON_GET_SERVICE_CLASS) I'm disappointed by the fact that there is a big difference between total_rqst_time and the sum of all other values.
It seems that with "normal" DML statements these two values are quite…Continue

Operational monitoring refers to collecting key system performance metrics at periodic intervals over time. This information gives you critical data to refine that initial configuration to be more tailored to your requirements, and also prepares you to address new problems that might appear on their own or following software upgrades, increases in data or user volumes, or new application deployments.... …Continue

I have a table A with 30,000 Records.
Module B selects the data from the table A.
This module B is called via online(CICS) and Batch mode.
This Module is called 30 million times in day. 20% of traffic is via Online mode and 80% of traffic is via Batch Mode.
In a second this Table is referred 30 times and in a minute 4500 times.
Each time Module B is triggered it selects data from Table A.
Whenever I do a select to table A. IO is caused and by…Continue

Empezaremos esta entrega hablando de unos de las implementaciones tal vez menos conocidas, es la referida al particionamiento en un servidor. En especial nuestro interés es más bien estratégico y queremos enseñarles como sabe usted que esta ante una instalación de este tipo. Para ello hemos estructurados dos partes, en la primera aprenderemos a darnos cuenta que estamos antes este tipo de instalación y entender su arquitectura estratégica y la segunda, donde…

The heart of today's data warehouse, big data and analytics initiatives is based around databases. Analysts show that transactional data and log data are top two types of data used in big data initiatives despite the immediate association of social data and unstructured content. DB2 for z/OS by example is robust, scalable, secure and provides some of the best transactional integrity. With all of this Mike Ferguson analyst and consultant concludes in his white paper : "All of this makes…Continue

Hold tight - this will probably freak the accounting world out. I was listening to an analyst call about big data earlier today. I asked the question whether data would soon have a value on the asset sheet. There was a resounding agreement that it would - if a suitable metric could be devised.
To me it all depends on whether an organization can put controls around the following (non-exhaustive) criteria :
Accurate data - bad data is like a virus to the business and could…

One of the techniques to improve database performance and achieve greater scalability is using table partitioning. According to live industry observations when you see the following symptoms you should consider table partitioning
Slow queries that return small amounts or no data
Slow queries that return large amounts of data
Blocking between readers and writers (inserts or updates)
As tables grow in size, it may be easier to manage your…Continue

With expression-based indexes, you can create an index that includes expressions. The performance of queries that involves expressions is improved if the database manager chooses an index that is created on the same expressions. Expression-based indexes are best suited when you want an efficient evaluation of queries that involve a column expression. Simple index keys consist of a concatenation of one or more specified…Continue
