Microsoft SQL Server has for many years attempted to auto-manage a lot of the administrative and performance characteristics of its database engine. Although some may disagree, SQL Server’s ease-of-use accolades in the areas of setup and basic administration are well deserved, but what about automatic performance management? Does SQL Server competently handle performance in a way that requires no DBA tuning or intervention? Perhaps a coy way to answer this question is by the following observation: If you visit one of the more popular SQL Server forums on the Internet (SQL Server Magazine’s), you will find over 2,000 posts in the performance question category of the site – more posts than in any category other than general administration. So the answer to the previous question is another question: if SQL Server performance analysis has been made obsolete by self-managed performance, then why so many questions on the topic?

The on-the-road performance of passenger cars are often discussed in terms of kilometres driven per MJ (or other unit of energy). This does not do justice to the different payloads that different cars are certified to carry, perhaps considering the poor correlation between required, actually used and available passenger and cargo space characterising the vehicle choice of many passenger car owners. Campaigns have occasionally been directed at increasing customer usage of the available payload (better trip planning, pool arrangements), but automobile sales material often mentions only km/MJ overall performance, if anything at all related to energy efficiency (mentioning energy performance is mandatory in some European countries, but mostly not done in North America).

VMware® VirtualCenter uses a database to store metadata on the state of a VMware Infrastructure environment. Performance statistics and their associated stored procedure operations constitute the largest and the most resource‐intensive component of the VirtualCenter database. Hence the performance of your VirtualCenter database depends upon the frequency at which you collect performance statistics and the level of detail of the statistics you store. VirtualCenter 2.5 features a number of enhancements that are aimed at greatly improving the performance and scalability of the performance statistics operations in the VirtualCenter database.

Adaptive Server® Enterprise (ASE) is a highly scalable, mission critical database server that provides a portable, multi-platform system for high performance data management.The new features of ASE 15.0 deliver an operational advantage with lower cost and risk, and they achieve higher performance on mixed workload systems. Testing with ASE 15.0 has shown an advantage in overall performance for transaction processing over MySQL 5.0, and many complex queries show significant improvements.

In general, the performance of a database is based on several critical factors. The factors include, but not limited to, hardware, operating system, data schema, concurrency, volume of data, type of application, data access pattern and database configuration. To meet the business demands, your database application must address three vital constraints – Performance, Scalability and Reliability – each of which needs customization of different but correlated elements. In this whitepaper, we are going to explore different strategies to considerably optimize the performance of MySQL in HP-UX 11.23 IPF.

It is used by most Fortune 500 companies and comprises modules for human resource management, accounting, logistics, etc. Like many other application systems, SAP R/3 is based on a commercial relational database system which is used to store all R/3 related data; e.g., a company’s sales information. When installing R/3, it is possible to choose among

Database tuning practice is mainly conducted as a consequence of user’s complaints on the performance. There is a need for a reactive monitoring and tuning tool enabling a real-time overview of the main resource consumers in order to detect and solve performance bottlenecks. With an assessment of the Oracle’s high-availability database, in terms of the main architectural components and their impact on performance, we have developed a Java tool for the efficient and resource-effective tuning of Oracle databases.

With the advent of web business, system performance is more important to businesses than ever before. A poorly performing web site is just as bad as one that is actually down, because users get frustrated and are unlikely to return. Databases are an integral part of these high profile systems. With the decreasing costs of computer hardware, businesses are building more and bigger databases, and the database administrators (DBAs) are being asked to take on more and larger databases.
