IBM Db2 SQL Performance Analyzer
IBM Db2 SQL Performance Analyzer provides information about resource usage and costs associated with SQL queries without you having to run them in Db2. Such analysis helps you tune your queries to achieve maximum performance and cost optimization.
IBM Db2 SQL Performance Analyzer enables you to determine the cost of running a query under the attach facilities of IMS, CICS®, and batch, as well as TSO, SPUFI, and QMF. The cost estimate is given in familiar units (such as CPU time, I/O count, and elapsed time), as QUNITS (a single number representing the overall cost), and as a monetary cost. The results provided by IBM Db2 SQL Performance Analyzer include SQL Enhanced Explain reports, SQL Query Limits reports, and SQL Trace information.
