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.
SbspacesAn sbspace is a logical storage unit composed of one or more chunks that store smart large objects.
Temporary sbspacesUse a temporary sbspace to store temporary smart large objects without metadata logging and user-data logging.
Comparison of temporary and standard sbspaces

Comparison of temporary and standard sbspaces

The following table compares standard and temporary sbspaces.

Table 1. Temporary and standard sbspaces
Characteristics	Standard sbspace	Temporary sbspace
Stores smart large objects	Yes	No
Stores temporary smart large objects	Yes	Yes
Logs metadata	Metadata is always logged	Metadata is not logged
Logs user data	User data is not logged for temporary smart large objects but is logged for permanent smart large objects if LOGGING=ON	User data is not logged Creation and deletion of space, and addition of chunks is logged
Fast recovery	Yes	No (the sbspace is emptied when the database server restarts) To set up shared memory without cleaning up temporary smart large objects, specify oninit -p. If you keep the temporary large objects, their state is indeterminate.
Backup and restore	Yes	No
Add and drop chunks	Yes	Yes
Configuration parameter	SBSPACENAME	SBSPACETEMP
