Many thanks for visiting my Blog..!! IBM DataStage 8. Most of these are improvements in DataStage Parallel Jobs only while a couple of them will help Server Job customers as well. Faster Performanace then Older Version Faster, faster, faster. A lot of tasks in DataStage 8. DataStage 8. It can open, understand and store XML schema files. The new XML read and transform stages are much better at reading large and complex XML files and processing them in parallel: 3. Transformer Looping The best Transformer yet.

The DataStage 8. With looping inside a Transformer you can output multiple rows for each input row. Transformer Remembering DataStage 8. A key change in a DataStage job involves a group of records with a shared key where you want to process that group as a type of array inside the overall recordset. I am going to make a longer post about that later but there are two new cache objects inside a Transformer — SaveInputRecord and GetSavedInputRecord 0 where you can save a record and retrieve it later on to compare two or more records inside a Transformer.

Here is an aggregation example where rows are looped. Click here to Know Pivoting through Transformer 4. Easy to Install Easier to install and more robust. Mind you — I jumped aboard the DataStage train in version 3.

You can send artefacts to the source control system and replace a DataStage component from out of the source control system.

High Availability Easier than ever High Availability — the version 8. On top of that there are new chapters for the high availability of the metadata repository, the services layer and the DataStage engine. Horizontal and vertical scaling and load balancing. Cluster support for WebSphere Application Server. Improved failover support on the engine. Solution Architects can draw a diagram of a data integration solution including sources, Warehouses and repositories. Vertical Pivot It is now available and it can pivot multiple input rows with a common key into output rows with multiple columns.

Key based groups, columnar pivot and aggregate functions. You can also do this type of vertical pivoting in the new Transformer using the column change detection and row cache — but the Vertical pivot stage makes it easier as a specialised stage.

Fixed and variable length records. Single or multiple record type files. Balanced Optimizer looks at a normal DataStage job and comes up with a version that pushes some of the steps down onto a source or target database engine.

IE it balances the load across the ETL engine and the database engines. Version 8. Also, we can now process XML data in parallel. If you think that is cool, it can also do it the other way around i.

It can also convert data from one XML format to another. Transformer Stage It is one of the most used and the most important stages on DataStage and it just got better in 8. Transformer Looping: Over the years DataStage programmers have been using workarounds to implement this concept. Now IBM has included it directly in the transformer stage.
