Role of the SERVERNUM configuration parameter in the multiple-residency chapter of the IBM Informix: Administrator's Guide

SERVERNUM specifies a relative location in shared memory. The value that you choose must be unique for each database server on your local computer. The value does not need to be unique on your network. Because the value 0 is included in the onconfig.std file, It is suggested that you choose a value other than 0 to avoid inadvertent duplication of SERVERNUM.
