Benefits of Configuring More Memory in the IBM z/OS Software Stack
Significant performance benefits can be realized by increasing the amount of memory that is assigned to various functions in the IBM® z/OS® software stack, operating system, and middleware products. IBM DB2® and IBM MQ buffer pools, dump services, and large page usage are just a few of the functions whose ease of use and performance can be improved when more memory is made available to them. The following benefits can realized: Reduced I/O operations Reduced CPU usage Improved transaction response time Potential cost reductions Although the magnitude of these improvements can vary widely based on several factors, including potential I/Os to be eliminated, resource contention, workload, co...
The Descendants of Thomas and Mary Lord of Rochdale (Lancashire) England
Thomas Lord was (b. ca. 1771) was a farmer and gamekeeper at Hollingworth, probably in Lancashire. He and his wife, Mary, had five children. Members of the family worked as farmers and weavers in the woolen industry. Their children immigrated to the United States in the 1840s. Their sons, Robert Lord (1801-ca. 1885), and Simeon Lea Lord (1880-1895) immigrated to New Bruswick, but Simeon returned to Connecticut, where he died. Descendants of Robert and Simeon lived in New Bruswick, Ontario, Nova Scotia, Connecticut, Massachusetts, Maine, and elsewhere.

DB2 10 for z/OS Performance Topics
DB2® 10 for z/OS can reduce the total DB2 CPU demand from 5-20%, compared to DB2 9, when you take advantage of all the enhancements. Many CPU reductions are built in directly to DB2, requiring no application changes. Some enhancements are implemented through normal DB2 activities through rebinding, restructuring database definitions, improving applications, and utility processing. The CPU demand reduction features have the potential to provide significant total cost of ownership savings based on the application mix and transaction types. Improvements in optimization reduce costs by processing SQL automatically with more efficient data access paths. Improvements through a range-list index sc...
