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.
Parallel database query (PDQ)You can manage how the database server performs PDQ and you can monitor the resources that the database server uses for PDQ.
Managing PDQ queriesThe database server administrator, the writer of an application, and the users all have a certain amount of control over the amount of resources that OneDB allocates to processing a query. The database server administrator exerts control through the use of configuration parameters. The application developer or the user can exert control through an environment variable or SQL statement.
DBA control of resources for PDQ and DSS queriesTo manage the total amount of resources that the database server allocates to parallel database and decision-support (DSS) queries, the database server administrator can set the environment variable and configuration parameters.
