DSXchange

I've noticed that the parallel FTP stage will write the file temporarily to
on my server. I want to change this be a different directory: Is this possible, where do I specify to tell datastage where to write these files?

In the project environment variables, I found the
variable and set that value, recompiled, and ran the job but no change in behavior.

TMPDIR when left blank will default to /tmp.

There are also setting in uvconfig file in DSHOME that have /tmp settings as default.

without seeing the temp files filenames it's hard to say which aspect of the tool is writing to it.

There is also at least one place in WAS that defaults to /tmp but it shouldn't have anything to do with running a job having the FTP stage.

Check the value of the TEMP environment variable.
