9-8 IBM Informix OnLine Database Server Administrator’s Guide
What Is Multiple Residency?
■ Create multiple configuration files and OnLine database server
environments that are precision-tuned for a specific use.
Because multiple OnLine database servers each have their own
shared-memory configurations and locations, you can create a con-
figuration file for each database server that reflects special tuning
requirements. Each application could run in an OnLine environment
designed especially for it.
■ Separately administer sensitive databases.
You might find it useful to isolate applications or databases that are
critically important, either for reasons of security or to accommodate
more frequent archiving than is required for the majority of the
databases.
■ Simulate and test distributed data transactions on a single host
computer (with IBM Informix STAR).
If you are developing an application for use with IBM Informix STAR,
you can perform your distributed data simulation and testing on a
single host machine for the sake of convenience. Later, when a net-
work of host machines is ready, you can install the application
without changes to application source code.
