ROOTOFFSET configuration parameter

ROOTOFFSET specifies the offset into an allocation of disk space (file, disk partition, or device) at which the initial chunk of the root dbspace begins.

UNIX Only:

On some UNIX platforms, it is not valid to set ROOTOFFSET to 0. When this parameter is set incorrectly, you must reinitialize disk space and reload data to resume proper operation of the database server. Before you configure the database server, always check your machine notes file for information about proper settings.
