Resolution

1. Make sure the below parameter is set up correctly in the properties.xml:
   tempDir=""
2. It should be set to a proper value, the folder has to be available and have write access to.
3. The default value is a temp folder within Clarity (example):
   tempDir="C:\clarity\temp"
4. Repeat on each server in cluster
5. Restart all services and retry.

Additional Information

• If Java tmpdir is set up in JVM in properties.xml, the folder should also exist and user has to have permissions to it.
• It is not mandatory to set up java tmpdir if Clarity tempdir is set. If set, the parameter has to be set correctly
• More information here: Setting -Djava.io.tmpdir on Clarity Java JVM parameters
