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
Manage disk spaceYou can use several utilities and tools to manage disk spaces and the data that the database server controls.
Manage sbspacesThis section describes how to create a standard or temporary sbspace, monitor the metadata and user-data areas, add a chunk to an sbspace, and alter storage characteristics of smart large objects.
Size sbspace metadataThe first chunk of an sbspace must have a metadata area. It is important to size the metadata area for an sbspace correctly to ensure that the sbspace does not run out of metadata space.

Size sbspace metadata

The first chunk of an sbspace must have a metadata area. It is important to size the metadata area for an sbspace correctly to ensure that the sbspace does not run out of metadata space.

When you add smart large objects and chunks to the sbspace, the metadata area grows. In addition, the database server reserves 40 percent of the user area to be used in case the metadata area runs out of space.

To ensure that this does not happen, you can either:

Let the database server calculate the size of the metadata area for the new sbspace chunk.
Specify the size of the metadata area explicitly.

For instructions on estimating the size of the sbspace and metadata area, see table performance considerations in the HCL OneDB™ Performance Guide. Also see Monitoring the metadata and user-data areas.
