Datastage Training Course Content

Sometimes DataStage is sold to and installed in an organization and its IT support staff are expected to maintain it and to solve DataStage users’ problems. In some cases IT support is outsourced and may not become aware of DataStage until it has been installed. Then two questions immediately arise: “what is DataStage?” and “how do we support DataStage?”.This white paper addresses the first of those questions, from the point of view of the IT support provider. Manuals, web-based resources and instructor-led training are available to help to answer the second.DataStage is actually two separate things.

In production (and, of course, in development and test environments) DataStage is just another application on the server, an application which connects to data sources and targets and processes (“transforms”) the data as they move through the application. Therefore DataStage is classed as an “ETL tool”, the initials standing for extract, transform and load respectively. DataStage “jobs”, as they are known, can execute on a singleserver or on multiple machines in a cluster or grid environment. Like all applications, DataStage jobs consume resources: CPU, memory, disk space, I/O bandwidth and network bandwidth.

DataStage also has a set of Windows-based graphical tools that allow ETL processes to be designed, the metadata associated with them managed, and the ETL processes monitored. These client tools connect to the DataStage server because all of the design information and metadata are stored on the server. On the DataStage server, work is organized into one or more “projects”.

There are also two DataStage engines, the “server engine” and the “parallel engine”.

The server engine is located in a directory called DSEngine whose location is recorded in a hidden file called /.dshome (that is, a hidden file called .dshome in the root directory) and/or as the value of the environment variable DSHOME. (On Windows-based DataStage servers the folder name is Engine, not DSEngine, and its location is recorded in the Windows registry rather than in /.dshome.)

The parallel engine is located in a sibling directory called PXEngine whose location is recorded in the environment variable APT_ORCHHOME and/or in the environment variable PXHOME
