You can change Environmental variable value in many ways:

DataStage Administrator (Where? : Change the value column)

Using C/C++ API (the DataStage development kit) you can build a self-contained program that can run anywhere on your system, provided that it can connect to a DataStage server across the network.

How to change the Environmental variable in Parallel job ?

Using the above specified API in a parallel routine (Make sure you don't call this routine simultaneously to change the same Environmental variable).

Search for "DSParams" or "Environment vairable" to know more about this. Not sure which input directory you are talking about.

I am not sure what exactly you want to change

..but if you want to change some variable in user_defined category then .... go to datastage administrator...in that select the project tab...in that go to properties button.......then to environment .....and to then look into the User Defined category....

If you want to change the category of some variable then this link might help you:

If you want to change the value when you request a job run, add the environment variable to the job as a job parameter. Set the default value of the job parameter to be $PROJDEF or $ENV. The first will pick up the value from whatever has been set in Administrator, the second will pick up the value from the executing user's operating system shell.

To change the value, simply provide a value when submitting the job run request. This will cause DataStage not to pick up the default value.

How can you not know what variable to change? How can you expect us to know?

Just change the value associated with it in the Administrator... it is defined there, is it not?

Are you talking about the fold where Datasets are landing?

If yes than you need to change your node configuration file to point the "resource disk" to the correct folder.

Are you sure its an environment variable and not a simple job parameter?
