In versions prior to Sybase IQ 15.1 ESD #3, the database option OS_FILE_CACHE_BUFFERING controls the file system buffering of both IQ Main dbspaces and IQ Temporary dbspaces. As of Sybase IQ 15.1 ESD #3, OS_FILE_CACHE_BUFFERING controls the file system buffering of IQ Main dbspaces only. The new database option OS_FILE_CACHE_BUFFERING_TEMPDB controls the file system buffering of IQ Temporary dbspaces.
See “Controlling file system buffering [CR 487762]” for a description of the database option OS_FILE_CACHE_BUFFERING_TEMPDB.
