I learn a lot about the Info on Datastage. Its good for the beginners and working People. It was precise and easy to learn, you can understand the way they teach in Real time Scenarios. The Trainer was great and its worth to join Realtimeexperts. Great work by RTE you save me a lot in learning the DWH and its basics examples.. Outstanding Datastage class, I learned a lot of new stuff. Great intro to Datawarehousing Concepts. I had no clue as to what was involved in learning SQL and Datastage. Now I got good Knowledge on Datastage

IBM InfoSphere DataStage is an ETL tool and part of the IBM Information Platforms Solutions suite and IBM InfoSphere. It uses a graphical notation to construct data integration solutions and is available in various versions such as the Server Edition, the Enterprise Edition, and the MVS Edition For Business Intelligence (BI) market is very much dependent on ETL architecture. The Extract, Transform and Loading products have become far more important in the data driven age. DataStage is one of the most important ETL tools which effectively integrate data across various systems. DataStage designs jobs that manage the collection, transformation, validation and loading of data from different systems to data warehouses. DataStage facilitates business analysis through its user friendly interface and providing quality data to help in gaining business intelligence. With IBM acquiring DataStage in 2005, it was renamed to IBM WebSphere DataStage and later to IBM InfoSphere.DataStage has four components namely Administrator, Manager, Designer and Director. DataStage has various versions such as Server Edition, Enterprise Edition, MVS Edition and DataStage for PeopleSoft.
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?â€.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
(“transformsâ€) the data as they move through the application. Therefore
DataStage is classed as an “ETL toolâ€, the initials standing for extract,
transform and load respectively. DataStage “jobsâ€, 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
“projectsâ€.
There are also two DataStage engines, the “server engine†and the “parallel engineâ€.
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
