Sybase IQ uses memory for several purposes:
Buffers for data read from disk to resolve queries
Buffers for data read from disk when loading from flat files
Overhead for managing connections, transactions, buffers, and database objects
The sections that follow explain how the operating system supports IQ's use of memory, how IQ allocates memory for various purposes, how you can adjust the memory allocations for better performance, and what you may need to do to configure the operating system so that enough memory is available for IQ.
