NAME

       installupdate - Invokes the Update Installation procedure

SYNOPSIS

       /sbin/installupdate [-nogui] [-u] {ris_server:}

       /sbin/installupdate [-nogui] [-u] {[cdrom_device], [cdrom_mount_point]}

OPTIONS

       On  systems  with graphics capability, this option invokes the text-based, menu driven user interface rather than the graphical user inter-
       face.  Invokes an unattended Update Installation. Unattended means that barring any problems during the Update Installation,  there  is	no
       user  interaction  required.  This option builds a kernel with all kernel components, automatically removes blocking software, and does not
       provide the option to archive obsolete files before the Update Installation process deletes them.

DESCRIPTION

       The installupdate command invokes the Update Installation. An Update Installation updates the  base operating system software to  the  next
       released  version of the operating system. The Update Installation preserves user files, data files, print and network configurations, user
       accounts, and any other system setup and customization you may have done.

       An Update Installation does not update layered products, but you can still perform an Update Installation if your system is installed  with
       layered	products.  Some layered products operate properly with the new version of the operating system and others must be reinstalled with
       a version that is compatible with the new version of the operating system. You are notified accordingly. You can delete these products dur-
       ing the Update Installation process and then reinstall them on the updated system.

       There  are two distribution methods for an Update Installation: From the operating system CD-ROM (from a mount point or CD-ROM device) Over
       a network connection to a Remote Installation Services (RIS) server that is serving the most recent version of the operating system

       The Update Installation is performed from single-user mode. You must be superuser or the user root to bring a system  down  to  single-user
       mode. Do not boot to single-user mode to perform an Update Installation.

       Whether	you  are using CD-ROM or RIS, the Update Installation process is started by entering the /sbin/installupdate command from the com-
       mand line.

       The functions performed during the Update Installation process include: Detecting and deleting obsolete system files, files that were  pre-
       viously	shipped  with the older version of the operating system but are not in the new release. You have the option to archive these files
       to a file name of your choice before they are removed from the system.  Checking for file types that you have changed since the	last  ver-
       sion  of the operating system. Certain file type conflicts prevent the Update Installation from continuing, and you must resolve these con-
       flicts before you can restart the Update. This feature preserves the integrity of the new operating system about to be installed.  Checking
       for  adequate free disk space to ensure the Update Installation has enough room for temporary processing and there is enough disk space for
       the new software subsets that were introduced in the new version of the operating system.  Saving unprotected  customized  files  to  files
       with extensions to preserve customizations that were made to unprotected system files.  These files are not expected to be modified and are
       not merge protected from the Update Installation, therefore they are saved with the  extension.	 Performing  merges  of  protected  system
       files.	These  are files that are shipped as part of the  operating system that are expected to be customized (for example, the /etc/hosts
       file). These files are merge protected, which means that user customizations are preserved and newly  introduced  functionality	is  merged
       into  the already customized file.  Using the setld command to load new software subsets.  Subsets previously installed are updated as well
       as any new mandatory subsets that were introduced in the new version of the operating system. Base operating system subsets  and  Worldwide
       Language  Support  (WLS) subsets are updated.  Building a custom kernel and rebooting the system with that kernel.  Executing user-supplied
       update_preinstall and update_postload files, if they exist, to perform customizations on the updated system.

       An Update Installation completes in 45 to 120 minutes. Actual time varies depending on your processor type, the number of software  subsets
       that have to be updated, network traffic, and the speed of the CD-ROM device. You need to respond to prompts only during the initial analy-
       sis phase of the Update Installation

       Postinstallation tasks may include manually merging file customizations into those files  that were not done automatically  and	rebuilding
       the  kernel  with  layered  product  kernel  components. It is recommended that you review the Update Installation log files located in the
       /var/adm/smlogs directory when the Update Installation is complete.

FILES

       Contains a log of the output that was displayed to the screen during the Update Installation.  Contains a list of the files that were saved
       to a extension.	Contains a list of the files that were saved to a extension.  Contains a list of the protected system files that failed to
       automatically merge during the Update Installation.
