System Performance

DC/UCF system performance largely depends on site-specific factors. Factors such as the system environment (both hardware and software), the number of systems running concurrently, and the type of work being done by each system make it difficult to prescribe any single method of system tuning.

DC/UCF system performance largely depends on site-specific factors. Factors such as the system environment (both hardware and software), the number of systems running concurrently, and the type of work being done by each system make it difficult to prescribe any single method of system tuning.
However, system performance problems generally are the result of resources not being available as required at runtime. This section discusses performance issues that you can address by adjusting parameters specified at system generation time.
To monitor performance trends, you can use DC/UCF statistics and histograms, as described in section 9, Statistics. You can display current performance information at runtime by using DCMT commands and the OPER task. To view the contents of the system log, you can use the OLP system task.
For more information on using DCMT, OPER, and OLP, see the
System Tasks and Operator Reference section
