Distributed Query Processing

Distributed query processing (DQP) improves performance in IQ multiplex configurations by spreading work across multiple nodes in the cluster.

You need not set any configuration options to activate distributed query processing. Unless you disable DQP by turning off the dqp_enabled Login Policy option or the dqp_enabled temporary database option, DQP occurs automatically for qualifying queries when:

Not all users connecting to a logical server may need to have their workload distributed at all times. Use the distributed query processing options to enable or disable DQP for sets of users, and at the individual connection level. Use the dqp_enabled Login Policy option to enable/disable DQP for sets of users. Use the dqp_enabled temporary database option to enable/disable DQP at the individual connection level.
