Analyzing long-term buffer pool performance
This topic describes how to view performance
data from several bpd files on the client to perform a long-term analysis
of buffer pool performance.
About this task
Related tasks:
- Before you can use this function, you must have performed the
tasks described in:
- Collecting data
- Creating activity reports and bpd files
Here, only bpd files are of interest. Long-term analysis requires at least one bpd file as input; however, the intention is to analyze data from multiple bpd files to span a longer period.
- Downloading files from the host to the client
One or more buffer pool data files must be available on the client (the files with the recommended file name extension bpd).
General remarks:
- Your client should have approximately 40 MB of available physical memory (random access memory) for this function. You can check this in the Windows Task Manager. Close other applications, if necessary.
- The data used for this function reflects the performance for the intervals for which trace data was collected and for the time frames that were specified with the GLOBAL and the BPACTIVITY command when the bpd files were created.
