AdministeringIn addition to administering the database server, you can tune performance, replicate data, and archive data.
System administrationThese topics contain concepts, procedures, and reference information for database and database server administrators to use for managing and tuning HCL OneDB™ database servers.
Administrator's ReferenceThe HCL OneDB™ Administrator's Reference includes comprehensive descriptions of HCL OneDB™ configuration parameters, the system-monitoring interface (SMI) tables in the sysmaster database, the syntax of database server utilities such as onmode and onstat, logical-log records, disk structures, event alarms, and unnumbered error messages.
Configuring and monitoring HCL OneDB™
Database configuration parametersThe HCL OneDB™ database server uses a configuration file, which is called the onconfig file, during initialization. This file contains default configuration parameter values. You can modify the parameter values to improve performance and other characteristics of the instance or database.
ROOTOFFSET configuration parameterROOTOFFSET specifies the offset into an allocation of disk space (file, disk partition, or device) at which the initial chunk of the root dbspace begins.

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.

onconfig.std value: ROOTOFFSET 0
values: Any value greater than or equal to 0
units: Kilobytes
takes effect: When disk is initialized (destroys all data)
