Environment Variables

There are many environment variables that affect the design and running of parallel jobs in InfoSphere® DataStage®. Commonly used ones are exposed in the InfoSphere DataStage Administrator client, and can be set or unset using the Administrator (see InfoSphere DataStage Administrator Client Guide). There are additional environment variables, however. This topic describes all the environment variables that apply to parallel jobs. The environment variables can be set or unset as you would any other UNIX or Windows system variables to the values indicated in their descriptions. You can also add the environment variables to the User Defined section in the InfoSphere DataStage Administrator environment variable tree.

The available environment variables are grouped according to function. They are summarized in the following table.

The final section in this topic gives some guidance to setting the environment variables.
