oracle/dfw/impl/common/TempFileManager --->Appeared many times.

It had a simple fix.

1. Check /tmp directory in your machine and check if having oracle-dfw* files created by a different user other than the "installation owner".

If so, delete them all.

2. If you want to have multiple installations, by different users, ensure to set the following java property Into the EXTRA_JAVA_PROPERTIES for the setDomainEnv.sh:

-Djava.io.tmpdir=<path>
