Before beginning the installation of SF Oracle RAC software, you can check the readiness of the systems where you plan to install SF Oracle RAC. The command to start the preinstallation check is:
installsfrac -precheck system1 system2 ...
# ./installsfrac -precheck galaxy nebula
The program proceeds in a non-interactive mode, examining the systems for licenses, depots, disk space, and system-to-system communications. The program displays the results of the check and saves the results of the check in a log file.
