Quick Beginnings for DB2 Extended Enterprise Edition for UNIX


All connection requests from client applications, whether they are local or remote, are allocated a corresponding coordinator agent (db2agent). In symmetric multiprocessor (SMP) systems, multipartition database systems, and single-partition database systems in which the intra_parallel database manager configuration parameter is enabled, the coordinator agent distributes the database requests to subagents (db2agntp), and these subagents perform the requests for the application. Once the coordinator agent is created, it handles all database requests on behalf of its application, coordinating the subagents that perform requests on the database.

A coordinator agent may be:

Idle and associated agents reside in an agent pool. These agents are available for requests from coordinator agents operating on behalf of client programs, or from subagents operating on behalf of existing coordinator agents. The number of available agents is dependent on the maxagents and num_poolagents database manager configuration parameters.

For additional information about agents and the configuration parameters used to control them, refer to the Administration Guide. For information about the DB2 process model, refer to the Troubleshooting Guide.
