Hello,
I've a question regarding Flash Cache parameters .
I've a 213 GB table , and I set at compute node the option:CELL_FLASH_CACHE : NONE
However at cell staorage If I query this object and their statistics:
CellCLI> LIST FLASHCACHECONTENT where dbUniqueName=xxxxxxxx and objectNumber=1191444 detail
cachedKeepSize: 0
cachedSize: 105948876800 -->98GB
cachedWriteSize: 93044736
columnarCacheSize: 0
columnarKeepSize: 0
dbID: 1166172376
dbUniqueName: xxxxxxxxx
hitCount: 240988
missCount: 31957
objectNumber: 1191444
tableSpaceNumber: 322
This info is from a unique cell, but the same statistics are similar en other storage cells (4).
If NONE is set at table level, the doc say that is not cached at flash cache the blocks from this object.
Other question, is why the cachedSize if, I multiple *4 storage cells (400GB) is the double of table segment, that is 200GB.
The cell storage version is: releaseVersion: 18.1.8.0.0.180906.1
Database version is 11.2.0.4.
Any know details about this options?
Thanks
Arturo
