Review the Environment Variables

Review the Environment Variables

Configure the environment variables to work with the Informatica installation.
The following table describes the environment variables to review on UNIX:
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.
INFA_DOMAINS_FILE
Contains the location of the domains.infa file. Clear this variable before you start the upgrade.
INFA_HOME
Contains the location of the Informatica installation directory. Clear this variable before you start the upgrade.
INFA_JDK_HOME
Location of the folder containing the supported Java Development Kit (JDK). Set the INFA_JDK_HOME environment variable if you are installing Informatica on AIX.
In the configuration file for your shell, for example the .bashrc file, set the INFA_JDK_HOME environment variable to the directory that contains the JDK. Verify that the login shell can access the INFA_JDK_HOME environment variable.
INFA_JRE_HOME
Location of the folder containing the supported Java Runtime Environment (JRE). Set the INFA_JRE_HOME environment variable to run the Informatica Upgrade Advisor on AIX.
In the configuration file for your shell, for example the .bashrc file, set the INFA_JRE_HOME environment variable to the directory that contains the JRE. Verify that the login shell can access the INFA_JRE_HOME environment variable.
JRE_HOME
If you install the Informatica services on a Linux machine, clear the JRE_HOME environment variable before you start 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.
Library path
Verify that the library path environment variables do not contain earlier versions of Informatica.
PATH
The installer appends file paths required by Informatica to the PATH environment variable. Verify that the length of the PATH environment variable does not exceed the system limits.
Verify that the PATH environment variables do not contain earlier versions of Informatica.
