Calculating the size of the root dbspace in the chapter on where is data stored in the IBM Informix: Administrator's Guide

ROOTSIZE specifies the size of the initial chunk of the root dbspace, expressed in kilobytes. The size that you select depends on your immediate plans for your database server.

To change ROOTSIZE after you initialize the database server, you must completely unload your data, reinitialize the server with the new ROOTSIZE, and reload your data.

In Extended Parallel Server, the ROOTSIZE parameter is optionally part of the coserver-specific section of the ONCONFIG file to override the value that is given in the global section of the ONCONFIG file.
