Configuring and maintaining the Informix database for UNIX

This topic contains information about the appropriate configuration and maintenance for the Informix® database.

Partitions

When configuring partitions:

Dedicated Informix server

For better performance, dedicate your CM database server machine to run Rational® Synergy. If you have a dedicated CM 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 is swapped to disk, which might slow CM server performance for large sites and at various usage times.

For more information about the Informix ONCONFIG file, see your Informix administrator documentation.
