On UNIX, the installer files are distributed as a tar file.
Use a native tar or GNU tar utility to extract the installer files to a directory on your machine.
You can extract the installer files in the following ways:
Installation DVD. Copy the Informatica tar file from the installation DVD to a directory on your machine and extract the installer files, or extract the installer files directly from the DVD to a directory on your machine.
FTP download. Download the Informatica installation tar file from the Informatica Electronic Software Download (ESD) site to a directory on your machine and extract the installer files.
