Datasync Consulting is the leading DB2 Linux, Unix and Windows (LUW) consultancy company in Australia. We have assembled the largest and most expert DB2 Performance Tuning team to assist clients to maximise the business value they derive from IBM DB2 databases. Our consultants have worked on a large variety of DB2 technology including DB2 BLU, DB2 Purescale, DPF, SQL Replication, Queue Replication, Optim Performance Manager (OPM), DB2 XML, STMM and HADR.
Datasync’s DB2 Performance Tuning service focuses on establishing the issues currently faced by a business and utilises a business value based remediation of the system. We know that tuning must return value to a business, for example, it may allow a capital based hardware upgrade to be deferred by 12 months. As such, we offer highly skilled consultants to work through the problems and solutions with our clients, to build and implement a roadmap to performance levels that matter to their business.
Our tuning approach focuses on gaining a holistic understanding of the DB2 performance tuning issue and desired performance outcome. With this understood and linked to the agreed business outcome, our highly experienced consultants will then work to verify and analyse the cause of the performance issue whilst keeping all parties informed. Drawing upon their own knowledge and that of the whole practice, our consultants will build options for the business owners to consider and, where appropriate, establish work-around solutions to ensure performance is restored in the short term while longer term solutions can be enabled.
DB2 SQL Performance Tuning
For many customers the immediate issue is the performance of SQL statements running within their application. Working with the application developers, Datasync’s DB2 performance tuning team are able to assist in identifying poor-performing SQL and developing queries and practices to improve the responsiveness of the application. In many situations this involves using our understanding of modern programming techniques to look for holistic answers that exploit the database and application technology.
DB2 Performance Tuning Tools
Some customers are looking for DB2 Performance Tuning Tools to assist their staff with the often daunting job of tuning a database. Datasync has gained extensive experience on many of the DB2 Tools available within the market place, such as the IBM Optim Performance Manager. We work with our client’s staff to define their requirements, move through to product selection and establish best practice for performance analysis and tuning around the Tool.
DB2 Performance Tuning Results
At Datasync we have completed a large number of DB2 Performance Tuning engagements which have greatly improved the value gained from our clients’ systems. In some instances we also helped our clients understand the cause of performance issues and provided guidance on where best to invest. For other clients it has simply been helping them to understand if an issue is not DB2. Some of the results are:
- Reduce overnight batch to 100% meet Business SLAs
- Reduce Backup and Recovery times to allow larger overnight batch windows
- Reduce ETL processing times to allow more data to be loaded into Data Warehouses
- Reduce screen response times to significantly decrease external customer complaint rates
- Reduce processing times to ensure contract compliance
- Reduce CPU usage to a level that allows a reduction in licencing costs
