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 blobspacesThis section explains how to create a blobspace and determine the blobpage size.
Determine blobpage sizeWhen you create a blobspace, use the size of the most frequently occurring simple large object as the size of the blobpage. In other words, choose a blobpage size that wastes the least amount of space.

Determine blobpage size

When you create a blobspace, use the size of the most frequently occurring simple large object as the size of the blobpage. In other words, choose a blobpage size that wastes the least amount of space.

For information about calculating an optimal blobpage size, see blobpage size considerations in the topics on the effect of configuration on I/O activity in the HCL OneDB™ Performance Guide.

If a table has more than one TEXT or BYTE column, and the objects are not close in size, store each column in a different blobspace, each with an appropriately sized blobpage. See Tables.
