sadm_uninstall.sh - Uninstall the SADMIN tools.
sadm_uninstall.sh [-d 0-9] [-h] [-v] [-y]
This script is use to uninstall a SADMIN Client or Server tools from one system. The script detect if it is running on a client or SADMIN server (looking at $SADMIN/cfg/sadmin.cfg). For security reason, when you run the script it will run in ‘dry run’ mode. This means that it will not change or remove anything on the system. But it will show you what it would do when you really uninstall SADMIN. To really uninstall the SADMIN tools, use the ‘-y’ command line option. Be aware that the SADMIN database will be deleted (drop) when uninstalling a SADMIN server installation, this is why the database password is asked during a server uninstall. The database users ‘sadmin’ and ‘squery’ will also be deleted. Lastly, the uninstall will not remove any O/S packages, that were installed (if any) during installation, because you may use one of these packages for some others purposes.
Below is an example of running an uninstall dry run on a client. Nothing is change on the system except that it is showing you what it would have done, if your ran it with the option ‘-y’. If you really want to uninstall SADMIN, use the ‘y’ option (sadm_uninstall.sh -y).
