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 CPU utilizationThe combination of operating-system and HCL OneDB™ configuration parameters can affect CPU utilization. You can change the settings of the HCL OneDB™ configuration parameters that directly affect CPU utilization, and you can adjust the settings for different types of workloads.
UNIX™ configuration parameters that affect CPU utilizationYour database server distribution includes a machine notes file that contains recommended values for UNIX™ configuration parameters. Because the UNIX™ parameters affect CPU utilization, you should compare the values in the machine notes file with your current operating-system configuration.
UNIX™ memory configuration parametersThe configuration of memory in the operating system can affect other resources, including CPU and I/O.

UNIX memory configuration parameters

The configuration of memory in the operating system can affect other resources, including CPU and I/O.

Insufficient physical memory for the overall system load can lead to thrashing, as Memory utilization describes. Insufficient memory for the database server can result in excessive buffer-management activity. For more information about configuring memory, see Configuring UNIX shared memory.
