{"Image DocumentName": "File I/O Tuning \u2013 VSAM RLS\u2026NOTES", "Image ImageDescription": "LRU Status status of local buffers under Buffer Manager Facility (BMF) control. \uf04a GOOD = BMF at or below goal. \uf04c ACCELERATED = buffer aging algorithms accelerated because BMF is over goal. \uf04c\uf04c RECLAIMED = buffer aging bypassed accelerated because BMF is over goal. BMF Valid % percent of BMF reads that were valid NOTE: BMF read hits is sum of valid and invalid hits. Buffers can be invalid because (A) data altered, or (B) CF lost track of buffer status. BMF READ HIT% = BMF READ% / BMF VALID%   100. BMF INVALID READ HIT% = BMF READ HIT% - BMF READ% Please see the notes provided on this slide.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
