DATASTAGE JOBS:

There are three basic types of DataStage job:

  1. 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 datawarehouse.
  2. Parallel jobs. These are compiled and run on the DataStage server in a similar way to server jobs, but support parallel processing on SMP, MPP, and cluster systems.
  3. 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.
