Abstract: A system and method for mapping transactions on both sides of a front-end server. One or more types of front-end transactions and one or more types of back-end transactions are identified. In addition, the times of occurrence of these transactions are identified. Possible associations between the identified front-end transaction types and the back-end transaction types are then built based on a time constraint. One or more of these associations are then eliminated such that each back-end transaction type is caused by one front-end transaction type and the number of associations between a given front-end transaction type and a given back-end transaction type remains constant.

Abstract: A method, system and computer program product for detecting when insufficient RAM is available in a computer system, and estimating the additional RAM needed to avoid excess paging. The invention uses memory management parameters to estimate the number of frequently-used pages stored in “virtual memory” on disk. If this estimate is nonzero for an appreciable period the amount of RAM is insufficient, and RAM equal to the estimate should be added to the system.
