How do I change DataStage so it no longer uses /tmp?
The following environment variables control the use of temporary space usage:
You will need to change or reset these variables (or create them if they do not exist) to override the default of /tmp for each existing project:
Also, you should backup and change the following parameters in uvconfig file in DSEngine
After the uvconfig file is changed you will need to shut down DataStage and regenerate the uv configuration.
bin/uv -admin -regen
Then restart DataStage as normal.
You should also check any configuration file used by Parallel Extender jobs to ensure they are not pointing the scratch resource to /tmp if this change is required.
