Answer 1

Note that if the values below are set in the shell initialization or system wide environment variables,

it could affect any other Java programs the customer uses.

Windows

The Update Installer uses the system specified default temp directory to download files.

Users can change the TMP environment variable to be able to change the default temporary directory that the Update Installer uses

Linux

For the Java based installers like Update Installer, the default temporary-file directory is specified by the JVM's system property "java.io.tmpdir".

You can add the following lines to the shell initialization files (e.g. .bashrc) or directly on command-line.

For Bash shells:

export JAVA_TOOL_OPTIONS=-Djava.io.tmpdir=/new/tmp/dir

or

export _JAVA_OPTIONS=-Djava.io.tmpdir=/new/tmp/dir

For tcsh shells:

set JAVA_TOOL_OPTIONS=-Djava.io.tmpdir=/new/tmp/dir

or

set _JAVA_OPTIONS=-Djava.io.tmpdir=/new/tmp/dir
