GOAL:
Why are the bi files of the target database much larger on a machine with a fast CPU than on a machine with a slow CPU.
GOAL:
Why are the bi files of the hot-spare database much larger on a machine with a fast CPU than on a machine with a slow CPU.
GOAL:
Does the CPU speed affect the size of the bi file?
FIX:
The larger bi file size with target (hot -spare) databases on machines with faster CPU's is because of the speed of the CPU and bi cluster aging. A cluster cannot be reused until it has aged properly, thus the bi file will continue to grow until the aging is satisfied. The cluster aging is used to guarantee bi write order and the algorithm used for a target database is different than that of the live database. A fast CPU is able to do more work, but the aging is not affected by CPU speed.
