There are a number of database manager configuration parameters
related to database agents and how they are managed.
The following database manager configuration parameters determine
how many database agents are created and how they are managed:
- Agent Pool Size (num_poolagents):
The total number of idle agents to pool that are kept available in
the system. The default value for this parameter is 100, AUTOMATIC.
- Initial Number of Agents in Pool (num_initagents):
When the database manager is started, a pool of worker agents is
created based on this value. This speeds up performance for initial
queries. All worker agents begin as idle agents.
- Maximum Number of Connections (max_connections):
Specifies the maximum number of connections allowed to the database
manager system on each database partition.
- Maximum Number of Coordinating Agents (max_coordagents):
For partitioned database environments and environments with intrapartition
parallelism enabled, when Connection concentrator is
enabled, this value limits the number of coordinating agents.
