For better performance, dedicate your Rational Synergy database server machine to run Rational Synergy. If you have a dedicated Rational Synergy database server machine, make the following change to the RESIDENT parameter in the Informix ONCONFIG file:
RESIDENT = 1
The default setting is 0. This parameter specifies whether shared memory remains in operating-system physical memory. If the default setting remains, shared memory are swapped to disk. Swapping shared memory to disk can slow Rational Synergy server performance for large sites and at various usage times.
For more information about the Informix ONCONFIG file, see the appropriate Informix administrator document.
