TRANSACTION_FLUSH <# of updates>
This keyword provides control for the maximum number of updates to a buffer (data or index) before it is flushed. The buffer may well be flushed prior to this number of updates because of the LRU (Least Recently Used) scheme (used for index caches but not data caches) or because of the checkpoint limit. This system parameter affects only buffers holding images for transaction controlled files. Reducing this value reduces the amount of buffering, slowing system performance; but decreases the amount of work to be performed during recovery. A value of zero causes the buffer to be flushed upon update.
Default: 500000
