The Project Portal system is distributed in one archive file (e.g. Kronodocdistr_linux_x_y_z.tar). The archive contains the Project Portal software itself and the Apache web server software. Other required software (e.g. Oracle, Perl) must be installed beforehand on the system according to About infrastructure setup for Red Hat Enteprise Linux.
Possible add-on or patch installation packages are separate archive files, which should be placed in the installer directory (see Installation directory structure). Add-ons are installed using the standard Project Portal installer script, which will detect any add-on or patch archives. Already-installed add-on and patch archives should be moved away to prevent accidentally re-installing them. Add-ons and patches are generally designed to be installed only once on a very specific Project Portal version, so re-installing should be avoided.
