FairCom DB follows a buffer aging strategy, which ensures updated cache pages for transaction-controlled files are eventually flushed to disk. The factors that affect when a buffer is flushed include the number of times a buffer has been updated and the number of checkpoints that have occurred since the buffer was last flushed. This section describes ways to tune the FairCom DB buffer aging strategy to avoid unnecessary flushing of updated buffers for transaction-controlled files.
