Advertising is directed to a select list of customers. A request comprising arguments defining a customer interest group is used to perform a blind search of a database. The database comprises public and private information about a customer wherein only the public information is viewable by the search requester. An advertisement is sent on behalf of the requester to the customer address(es) of customer(s) found in the blind search such that private information is not provided to the requester.

A partitioned processing system is disclosed wherein a workload calculation is implemented for at least one partition. CPU utilization and I/O throughput information is used in calculating resource control parameters which is indicative of resource usage for the partition. The system collects and analyzes the computer system capacity data in a partition which determines a sizing metric. The system includes a manager in the computer system which issues a command to obtain throughput information of a computer system first partition, and issues a command to obtain resource utilization information of the computer system first partition. The manager then calculates a resource control parameter using the information obtained. The system includes a monitor which indicates resource allocation responsive to the resource control.

Inter-partition message passing method, system and program product for throughput measurement in a partitioned processing environment

A method, system and program product for determining a cost differential resulting from a migration of computational workloads between computer platforms is disclosed herein. Information regarding current and planned hardware and software use on the computer platforms and the costs associated therewith is provided and supplemented with model data including historical data and industry averages. A cost and capacity measurement associated with the current and planned use and cost is derived. A required processing capacity migration between platforms is determined for a proposed computational workload migration therebetween and a resultant cost and capacity measurement is calculated for each platform to determine the resultant cost differential.

The information technology environment and requirements of a business entity are evaluated via an interactive engagement process, system and program product to successively match the entity's needs to a set of information technology solutions so as to generate a business solution deliverables such as a formal solution proposal. The engagement entails the determination of the entity's ability to participate in the evaluation. The engagement next includes partitioning the entity's information technology infrastructure into segments along the lines of established business criteria, receiving profile information from the entity thereon and mapping the profiled segments to potential solutions creating an ordered listing of solutions. Ordered solutions may be selected for detailed investigation including a further profiling of the segment to which the solution is to be applied and a workload analysis of the proffered solution. Upon successful completion of the workload analysis a business solution proposal and other deliverables may be generated.

A mechanism for handling processing errors in a computer system. The mechanism includes a first means for processing a stream of instructions, second means for detecting an error caused by a timing dependant defect and occurring during processing of the instruction by the first means and third means for varying the instruction processing cycle time of the first means in response to the detection of the error by the second means, and for causing the second means to retry at least a portion of the instruction subsequent to the varying. In a preferred embodiment, the mechanism uses the variable frequency oscillator, controlled by recovery code, to increase the system clock cycle time by a specified time (Textend) following what has been determined to be a critical fail and after normal retry has been unsuccessful. The increased cycle time extends the net slack and, thereby, provides tolerance to certain AC (path delay) defects which have developed in any cycle time dependant latch to latch segment. The time (T) is chosen based on maximum cycle time restrictions resulting, for example, from the pipelining of data in system cables.
