Single Coserver on a Single-Node Platform

A configuration that consists of a single coserver on a single node is best suited to a uniprocessor or an SMP computer that:

• has approximately 10 or fewer CPUs (in the case of an SMP computer).
• has an amount of physical memory that is comparable in size to the address space of a single process.
• has enough local disk space to support the data that is required for the intended application.

If your configuration consists of multiple small nodes, configure one coserver per node. A single coserver on a single node is easy to administer. You do not need a coserver-specific section in the ONCONFIG file. You can use the onconfig.std file as a template for a single coserver configuration.

Parallel processing can occur within a single coserver. The NUMCPUVPS parameter indicates the number of CPUs that are available to the database server for parallel processing.
