Coserver-specific configuration parameters in the chapter on configuring the database server in the IBM Informix: Administrator's Guide

The COSERVER configuration parameter specifies the numeric identification of a coserver. The coserver number must be unique among all coservers within Extended Parallel Server. The coservers must be numbered consecutively, starting at 1.

The COSERVER parameter begins a coserver-specific section in your ONCONFIG file.

You can assign COSERVER 1 to any node. To facilitate administration, you might want to assign COSERVER 1 on NODE 1, COSERVER 2 on NODE 2, and so forth.

Clients specify a coserver name when they connect to a connection coserver. The COSERVER parameter is part of this coserver name, which has the following format:

dbservername.coserver-number

In the name, dbservername is the value that you assign to the DBSERVERNAME configuration parameter when you prepare the ONCONFIG configuration file. And coserver-number is the value that you assign to the COSERVER configuration parameter for the connection coserver.
