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.
ROOTSIZE configuration parameterUse the ROOTSIZE configuration parameter to specify the size in kilobytes of the initial chunk of the root dbspace. The size that you select depends on your immediate plans for your database server.

ROOTSIZE configuration parameter

Use the ROOTSIZE configuration parameter to specify the size in kilobytes of the initial chunk of the root dbspace. The size that you select depends on your immediate plans for your database server.

The database server uses the value of the ROOTSIZE configuration parameter only during a complete disk initialization. Changing the ROOTSIZE value after the initial chunk of the root dbspace has been created will have no effect.

onconfig.std value: ROOTSIZE 200000ROOTSIZE 300000
if not present: 0
values: 50,000 through maximum capacity of the storage device
units: Kilobytes
takes effect: When disk is initialized (destroys all data)
