DataStage compile error 65280; Couldn't change directory to /tmp

Error when trying to compile parallel (PX) jobs in a project.

The compilation errors include the following:

Subprocess command failed with exit status 65280.
Output from subprocess: Couldn't change directory to /tmp : No such file or directory

Solution :

Could be a corrupted DSParams file.

Check whether the job compile works when imported in to another project.

If the job(s) that are failing compile can be successfully compiled when imported in another project, copy the DSParams file from the working project into the non-working project.
