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 configuration parameters that affect CPU utilization

Your 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.

The following UNIX parameters affect CPU utilization:

Semaphore parameters
Parameters that set the maximum number of open file descriptors
Memory configuration parameters
