Hello,

I am new on using datastage. I just like to ask for information(function/use) regarding some datastage components:

- lookup stage
- hashfile stage
- sorting stage
- dataset stage

I know this is a silly question but I really want to learn this stuff. Thanks in advance! :D

Hi,

Lookup Stage: You don't have lookup stage in server. In server you do Lookups using Hashed files.

In parallel version you have a lookup stage for performing lookup's.

Sorting Stage: As the name implies, it is used for sorting.

DataSet Stage: The Data Set stage is a file stage. It allows you to read data from or write data to a data set

Dont get confused between server and parallel stages and DataStage documentation is the best place to start with.

welcome

Online manual is best to start with.

From your Start menu, navigate to 'Ascential DataStage / Online Manuals / DataStage Documentation'. From that pdf, scroll down and open the Server Job Developer's Guide for Server and the Parallel Job Developer's Guide for PX jobs. It's all there. I'd also suggest you check out the Designer Guide as well. At the very least.
