DB2 CPU and Response Metrics

摘要

DB2 requests originate from a variety of diverse sources including batch, CICS, DDF, and SAP. Related DB2 CPU usage can be recorded in RMF, DB2, SMF 30, and other subsystem records. Proper selection and interpretation of these values will vary with transaction source, DB2 environment, product levels, and analysis objectives. Analysts must be careful to include all desired values and avoid multiple counting of the same logical utilization. This paper will discuss the sources and analysis of DB2 CPU metrics and corresponding response times. Examples will include CICS, DDF, and SAP.
