Abstract
For each database subsystem in a plurality of database subsystems running in a logical partition (LPAR), the systems and techniques include collecting data from buffer pools on a periodic interval, monitoring real storage availability on the LPAR, calculating an input/output (I/O) intensity score for each buffer pool for the periodic interval, ranking the buffer pools based on the I/O intensity score, calculating a cumulative I/O intensity score for each buffer pool across a cycle of multiple periodic intervals, ranking the buffer pools based on the cumulative I/O intensity score, and selecting a buffer pool candidate for page fixing. The buffer pool candidate for page fixing is a highest-ranked buffer pool from the plurality of buffer pools during the cycle based on the cumulative I/O intensity score that satisfies the real storage availability on the LPAR.
