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.
Performance GuideThe HCL OneDB™ Performance Guide describes how to configure and operate your HCL OneDB™ database server to improve overall system throughput and to improve the performance of SQL queries.
Effect of configuration on I/O activityThe configuration of your database server affects I/O activity.
Chunk and dbspace configurationThe number of disks that you use and the configuration of your chunks, dbspaces, and blobspaces affect the performance of your database server. You can improve performance by planning disk use and the configuration of chunks, dbspaces, and blobspaces.
Associate disk partitions with chunksYou should assign chunks to entire disk partitions. When a chunk coincides with a disk partition (or device), it is easy to track disk-space use, and you avoid errors caused by miscalculated offsets.

You should assign chunks to entire disk partitions. When a chunk coincides with a disk partition (or device), it is easy to track disk-space use, and you avoid errors caused by miscalculated offsets.

The maximum size for a chunk is 4 terabytes.
