Datastage 8.5 Enhacements


It was  more faster than  before versions.
All the  tasks become faster than previous version 8.1 .

Tasks are like save, renaming, compiling etc.

The run time of the jobs has been improved.

In DataStage transformer Stage is one of the important stage.


Transformer looping has been included in the transformer stage by I.B.M

There are two types of looping  available here.

Where we can output multiple O/P( Output )  links for single I/P( Input Link) Link.

For Example:

Input:

Name     Address-1       Address-2       Address-3

Manikanta    Palakol    Westgodavari   AndhraPradesh




Output will be

Name     Address

Manikanta    Palakol
Manikanta    WestGodavari
Manikanta    AndhraPradesh


This achieved  with the new system  variable @ ITERATION


System Variables:

@ ITERATION : used in the looping mechanism

LastRow(): Indicated the last row in the job

LastRowInGroup(): will return the last row in the group based  on the key.
