Review the Environment Variables

Review the Environment Variables

Configure environment variables for the Informatica installation.
The following table describes the environment variables to review:
Variable
Description
IATEMPDIR
Location of the temporary files created during installation. Informatica requires 1 GB disk space for temporary files.
Configure the environment variable if you do not want to create temporary files in the
/tmp
directory.
If you want to change the default
/tmp
directory, you must set IATEMPDIR and _JAVA_OPTIONS environment variables to the new directory.
For example, set the variable to export IATEMPDIR=/home/user.
Unset the IATEMPDIR variable after the installation.
_JAVA _OPTIONS
Configure the environment variable to change the temporary directory.
If you want to change the default /tmp directory, you must set IATEMPDIR and _JAVA_OPTIONS the environment variables to the new directory.
For example, set the variable to export _JAVA_OPTIONS=-Djava.io.tmpdir=/home/user.
Unset the JAVA _OPTIONS variable after the installation.
LANG and LC_ALL
Change the locale to set the appropriate character encoding for the terminal session. For example, set the encoding to
Latin1
or
ISO-8859-1
for French,
EUC-JP
or
Shift JIS
for Japanese, or
UTF-8
for Chinese or Korean. The character encoding determines the types of characters that appear in the UNIX terminal.
DISPLAY
Unset the DISPLAY environment before you run the installer. Installation might fail if the DISPLAY environment variable has some value.
Make sure that the NOEXEC flag is not set for the file system mounted on the /tmp directory.
