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 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
