Configuring the Hardware and Installing Windows NT 27
The exact shutdown strategy depends on your own environment, such as which
R/3 installation (two-tiered or three-tiered installation) or UPS sizing is used.
If you have a distributed system with several application servers connected to
different UPS systems, you have to consider some things.
The monitoring service, loaded on every server connected to the UPSs, is
responsible for the system shutdown of its server. If the utility power fails then it
fails usually for all UPS systems. When configured, the monitoring services will
shut down all servers and all works fine.
But if only one or not all UPS systems lose their utility power and you have
configured the servers so that they only shut down their own services and
applications, that could cause unexpected problems because important parts of
the SAP R/3 system would be shut down and other parts are still running.
Therefore, the system shutdown for the servers must be configured depending on
the kind of server it is.
Initiate the following actions (in the shutdown.cmd) on the respective server if the
utility power of its UPS fails:
1. On a centralized server (two-tiered solution)
• Notify all R/3 users about an impending system shutdown.
• Shut down the centralized R/3 system instance.
• Stop the R/3 central instance service.
• Shut down the database.
• Shut down the operating system.
2. On a database server without application or central instance
• Notify all R/3 users about an impending system shutdown.
