Performance aspects of IMS Meagher, Robert Gerard
Abstract
This paper deals with the tuning of the data base management system IMS. We will look at IMS in some detail; in particular, we will consider those aspects of IMS which are thought to have a measurable effect on performance at an IMS installation. These are: the original design of the data base, the adoption of logical relationships and secondary indexes and the choice of access method. Other features are thought to have a lesser effect but some of these will also be considered. These aspects will be evaluated by their ability to decrease processing time, increase flexibility and/or decrease storage requirements. The proposals presented in the first part of the paper will be further evaluated in the final chapter. The experiences of three IMS users will be incorporated to support or refute these proposals, as well as to provide insight into the kinds of performance studies being done, when they are done and what results are expected.
