DATASTAGE JOB TYPES

There are three basic types of DataStage job:
Server jobs:
These are compiled and run on the DataStage server. A server job will connect to databases on other machines as necessary, extract data, process it, then write the data to the target data warehouse.
Parallel jobs:
These are available only if you have Enterprise Edition installed. Parallel jobs are compiled and run on a DataStage UNIX server, and can be run in parallel on SMP, MPP, and cluster systems.
Mainframe jobs:

These are available only if you have Enterprise MVS Edition installed. A mainframe job is compiled and run on the mainframe. Data extracted by such jobs is then loaded into the data warehouse.
