Changing DataStage to use an Alternate Directory for Temporary Storage

Technote (FAQ)


Question

How do I change DataStage so it no longer uses /tmp?

Answer

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:

TMP
TEMP
TMPDIR
APT_FIFO_DIRECTORY
APT_PM_SCORE_DIR

Also, you should backup and change the following parameters in uvconfig file in DSEngine

UVTEMP=<new directory>

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.
