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.
Monitoring resources used for PDQ and DSS queriesYou can monitor the resources (shared memory and threads) that the Memory Grant Manager (MGM) has allocated for PDQ queries and the resources that PDQ and decision-support (DSS) queries currently use.

Monitoring resources used for PDQ and DSS queries

You can monitor the resources (shared memory and threads) that the Memory Grant Manager (MGM) has allocated for PDQ queries and the resources that PDQ and decision-support (DSS) queries currently use.

You monitor PDQ resource use in the following ways:

Run individual onstat utility commands to capture information about specific aspects of a running query.
Execute a SET EXPLAIN statement before you run a query to write the query plan to an output file.
