With the POSIX installation program, you can carry out an initial installation or an upgrade installation of POSIX, manage POSIX file systems and add or delete software program packages.
The POSIX installation program is started using /START-POSIX-INSTALLATION and can be called in interactive or batch mode:
In interactive mode, you enter the data required in screen forms. Incorrect entries and inconsistencies are reported in interactive mode, so that you can immediately correct your entries. For further information, see the section “POSIX installation program in interactive mode”.
In batch mode, you record the data required for installation in parameter files in a precisely defined layout. Invalid parameter files will cause the POSIX installation program to abort. For further information, see the section “POSIX installation program in batch mode”.
The actions of the installation program are logged, see the section “Logging the installation”.
For detailed information on which steps are needed for an initial or an upgrade installation, see the section “Initial installation of POSIX” or the section “Upgrade installation of POSIX”.
