Creating New Maps

If the maps supplied with InfoSphere® DataStage® do not meet your needs, you can create new ones and use these in your jobs.

You are most likely to want to produce a variant of an existing map rather than add an entirely new one, InfoSphere DataStage allows you to base a new map on an existing one and just add or alter the required mappings. You do this by creating a table and adding it to a map to make a new map.

A map is defined by a Description, which in turn calls upon a Table to define the actual mappings. To create a new map, you need to define a Description and a Table.

When you want to produce a variant of an existing map it is important that you create a new map based on the existing one. Under no circumstances should you edit one of the maps supplied with InfoSphere DataStage.

Maps are created using the NLS administration tool. This is run in an engine shell. You need to have InfoSphere DataStage Administrator status in order to be able to run this.
