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.

Effect of configuration on CPU utilization

The 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.

Multiple database server instances that run on the same host computer perform poorly when compared with a single database server instance that manages multiple databases. Multiple database server instances cannot balance their loads as effectively as a single database server. Avoid multiple residency for production environments in which performance is critical.
