Starting an R/3 System: Windows NT 

The following describes how to start the R/3 System or individual instances using the SAP Service Manager. You can also perform these tasks using the Microsoft Management Console (MMC). SAP recommends the use of the MMC as it provides many new functions and simplifies system management. For more information, see Microsoft Management Console: Windows NT.

To start an R/3 System that only consists of one central instance:

  1. Log on to Windows NT as the SAP administrative user ( <SAPSID>ADM , for example C11ADM ).

    2. The R/3 service ( SAP<SAPSID>_<Instance number> , for example SAPC11_00 ) is always started automatically when the Windows NT system is booted. The R/3 administrator does not therefore need to perform any additional actions to start the service. The information in the window Services (Control Panel ® Services) allows you to check that the R/3 service has been started (if this is the case, the service has the Status Started).

    If the R/3 service has not been started, carry out the steps described in R/3 System on Windows NT: Problem Analysis.

  2. Start the R/3 System:

The start procedure starts the database system as well as the central R/3 instance. If the database system is already running, only the instance is started.

When the stoplights for all processes shown in the SAP Service Manager window are "green," the R/3 System is started and is ready to be logged on to. The R/3 System continues to run even if you close the window or log off of the Windows NT system.

If a process did not start correctly, analyze the problem as described in R/3 System on Windows NT: Problem Analysis. Stop the instance, correct the error, and restart the instance. It is not possible to restart an individual process.

To start an R/3 System that consists of several instances:

  1. Start the database and at least the central R/3 instance. To do this, proceed as described in the section To start an R/3 System that only consists of one central instance.
  2. You can start additional instances with the SAP Service Manager or with the CCMS from the R/3 System.

To reach the CCMS start-up functions, select Tools ® Administration ® Computing Center ® Management System ® Control ® System Monitor in the R/3 main menu.

If problems occurred, analyze these as described in R/3 System on Windows NT: Problem Analysis, correct the error, and repeat the start procedure.
