The Datastage configuration
file is a master control file (a textfile which sits on the server side) for
jobs which describes the parallel
system resources and architecture. The configuration file provides
hardware configuration for supporting such architectures as SMP (Single machine with multiple CPU
, shared memory and disk), Grid ,
Cluster or MPP (multiple CPU, mulitple nodes and dedicated memory per
node). DataStage understands the architecture of the system through this file. This is one of the biggest strengths of Datastage.
