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.
Table performance considerationsSome performance issues are associated with unfragmented tables and table fragments.
Placing tables on diskTables that the database server supports reside on one or more portions of one or more disks. You control the placement of a table on disk when you create it by assigning it to a dbspace.
Using multiple disksYou can use multiple disks for dbspaces, logical logs, temporary tables, and sort files.
Using multiple disks for logical logsYou can distribute logical logs in different dbspaces on multiple disks in round-robin fashion to improve logical backup performance. This scheme allows the database server to back up logs on one disk, while performing logging operations on the other disks.

Using multiple disks for logical logs

You can distribute logical logs in different dbspaces on multiple disks in round-robin fashion to improve logical backup performance. This scheme allows the database server to back up logs on one disk, while performing logging operations on the other disks.

Keep your logical logs and the physical log on separate devices to improve performance by decreasing I/O contention on a single device. The logical and physical logs are created in the root dbspace when the database server is initialized. After initialization, you can move them to other dbspaces.
