Datastage Enterprise edition have the facility to specify the nodes on which the process has to be carried out. Node pool constraint is the Datastage property used to restrict stages to use particular nodes only. For example, Datastage parallel job having basic transformer will fail in the distributed parallel environment. By using node pool constraint and configuration file basic transformer will be restricted to use only local nodes.

resource constraint - two types

resource disk - space for application creted datasets
resource scratch disk - runtime space created by dsengine when applications run
