The following topics in the IBM Informix: Administrator's Guide for a discussion of residency:

• Resident portion of shared memory in the shared-memory chapter
• Setting database server shared-memory configuration parameters in the chapter on managing shared memory

The RESIDENT parameter specifies whether resident and virtual segments of shared memory remain resident in operating-system physical memory.

Some systems allow you to specify that the resident portion of shared memory must stay (be resident) in memory at all times. If your operating system supports forced residency, you can specify that resident and virtual segments of shared memory not be swapped to disk.

To modify the RESIDENT parameter dynamically, use the onutil SET command. Example:

%onutil
 RESIDENT 0;
