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 GuideThe HCL OneDB™ Administrator's Guide provides the information required to administer HCL OneDB™.
Disk, memory, and process management
Data storageThe database server uses physical units of storage to allocate disk space. It stores data in logical units. Unlike the logical units of storage whose size fluctuates, each of the physical units has a fixed or assigned size that is determined by the disk architecture.
Amount of disk space needed to store dataTo determine how much disk space you require, follow these steps:
Amount of space that databases requireThe amount of additional disk space required for the database server data storage depends on the requirements of users, plus overhead and growth.

Amount of space that databases require

The amount of additional disk space required for the database server data storage depends on the requirements of users, plus overhead and growth.

Every application that users run has different storage requirements. The following list suggests some of the steps that you can take to calculate the amount of disk space to allocate (beyond the root dbspace):

Decide how many databases and tables you must to store. Calculate the amount of space required for each one.
Calculate a growth rate for each table and assign some amount of disk space to each table to accommodate growth.
Decide which databases and tables you want to mirror.

For instructions about calculating the size of your tables, see your HCL OneDB™ Performance Guide.
