A survey on autonomic self-optimizing systems

In an on demand business, information technology, IT, components produced by high-tech companies over the past decades are so complex that IT professionals are challenged to effectively operate a stable IT infrastructure. It is the complexity of the IT components themselves that have helped fuel this problem. An exponential growth has occurred in the number and variety of systems and components. The value of database technology and the Internet have fueled significant growth in storage subsystems, which now are capable of holding terabytes of structured and unstructured information. Our information society has created unpredictable and highly variable workloads for these networked systems. And these increasingly valuable, complex systems require highly skilled IT professionals to install, configure, operate, tune and maintain them. In this survey paper, we discuss about autonomic Computing, self optimizing systems and its components with respect to DBMS and future work to be carried out in this area. The difficult and complex tasks are performed through autonomic way with low cost, reduction of labor and in an efficient manner. ICIC International �2011 ISSN.
