The Peek stage is a Development/Debug stage. It can have a single input link and any number of output links.
The Peek stage lets you print record column values either to the job log or to a separate output link as the stage copies records from its input data set to one or more output data sets.
1. Design :
We are using below design to demonstrate the functionality of PEEK stage in datastage. Job design is having 3 stages, Row Generator , data source, for generating the dummy data for the job. Here, we can use any data source whether it is DB, dataset or flat files. Transformer, just as a stage, creating negative values of source data. Peek for Peeking :-)
