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.
Storage characteristics of sbspacesAs the database server administrator, you can use the system default values for these storage characteristics, or you can specify them in the -Df tags when you create the sbspace with onspaces -c. You can change these sbspace characteristics with the onspaces -ch option.
Last-access timeWhen you create an sbspace, you can specify whether the database server must keep the last time that the smart large object was read or updated with the ACCESSTIME tag of the onspaces -c -Df option.

Last-access time

When you create an sbspace, you can specify whether the database server must keep the last time that the smart large object was read or updated with the ACCESSTIME tag of the onspaces -c -Df option.

The default is “ACCESSTIME=OFF�?. The database server keeps this last-access time in the metadata area.
