Review the buffer pool environment and recommend changes to the number of buffers in each subpool for optimized performance.
Get information on the efficiency of OSAM cached buffers in a coupling facility, and gauge the effect of changing the amount of storage allocated to OSAM buffers in CF.
Model user changes to the buffer pool configuration to evaluate to any impacts before they are implemented.
Identify wasted storage and determine if adding or subtracting buffers will improve the performance of a selected buffer pool.
Determine which databases are the heaviest users of each subpool, and perform “what if” scenarios analysis. Be certain of the impact of a change before it is implemented.
Explore subpool data usage for the pool configuration, buffer request rate and performance data. Examine database performance with a list of all data sets, hit ratio, buffer request rate and I/O rate.
