Configuring the Hardware and Installing Windows NT 25
Which Modules Should Be Installed?
• For the servers connected to a UPS serial port that you want to be monitored,
install the monitoring service (UPS Monitoring Module).
• For UPS monitoring and configuration on this server, select the graphical user
interface program (User Interface Module).
• You don't have to install the user interface on the monitored server. You can
remotely monitor and configure a server over the network from another
machine. This machine need not be connected to a UPS port. You install only
the user interface on this machine.
• The graphical user interface program has the capability to perform monitoring
across domains and subnetworks.
• Rights for access to the monitoring service are granted by the Windows NT
user administration. There is no extra user administration used.
Note: You will be unable to configure PowerChute
plus for a server locally if you
do not select the user interface. We recommend that you install both modules on
the servers which are connected to a UPS advanced port.
Server Shutdown in a SAP R/3 Environment
If the power fails and the PowerChute plus software shuts down your operating
system without shutting down your R/3 systems, R/3 applications and databases
close abnormally, which may cause files to be improperly closed, user requests
lost, and databases corrupted.
The PowerChute
plus software supports a command file named shutdown.cmd
located in your PowerChute
plus installation directory, which can be executed
before the PowerChute
plus software shuts down your operating system. You
have to set up a configuration parameter which decides how much time it will take
to execute the shutdown.cmd file successfully.
Calculate all time parameters for application and operating system shutdowns
carefully and generously. Simulate a power failure and test your system before
you run it in a production environment. For more information about setting up the
timing parameters and application shutdown with the shutdown.cmd file, please
refer to the
PowerChute plus User’s Guide for Windows NT.
The SAP R/3 system provides the following command line programs to start and
stop R/3 instances, databases and application services.
• sapstart -- Starts an R/3 instance
• sapsrvkill -- Stops an R/3 instance
• sapntwaitforhalt -- Waits for a successful shutdown of an instance
• ntscmgr -- Starts or stops an R/3 service (Windows NT service)
• sapdba --To start or stop the database
The R/3 architecture allows you to do this remotely. For example a server with the
central instance running can start or stop the service and the instance of another
application server. For an entire list of the command line programs and two
example scripts for starting and stopping an R/3 system with command line
programs refer to the SAP R/3 system online documentation.
