Starting and Stopping the SAP System (Microsoft Windows)

Use

You are starting the SAP system with the Microsoft Management Console (MMC). With a newly installed MMC, you only start installed SAP instances locally on the host that you are logged on to. If the MMC is configured for central system administration, you can start the entire SAP system from a single host.

Starting the SAP System

1. Start the MMC on the central system host by choosing Start ® Programs ® SAP System Management Console.

2. In the tree of nodes, choose the central instance. If you have configured the MMC for central administration, choose the node of the SAP system.

3. Click the right mouse button to display the context menu.

4. Choose Start. The following is started, depending on whether you have selected an individual instance or the SAP system:

¡ The central SAP instance and database

¡ The SAP system, all dialog instances, and the database

5. If the MMC is not configured in such as way that it permits central system administration, repeat the above steps on the hosts of all dialog instances.

Stopping the SAP System

...

1. Start the MMC on the central system host by choosing Start ® Programs ® SAP System Management Console.

2. In the tree of nodes, choose the central instance. If you have configured the MMC for central administration, choose the node of the SAP system.

3. Click the right mouse button to display the context menu.

4. Choose Stop. The following is stopped, depending on whether you have selected an individual instance or the SAP system:

¡ SAP central instance

¡ SAP system and all dialog instances

The database is not stopped. You must stop it separately.

5. If the MMC is not configured in such as way that it permits central system administration, repeat the above steps on the hosts of all dialog instances.

Starting and Stopping the SAP System (Unix)

Use

You can use the following commands under UNIX to start and to stop the SAP central instance and the database system.

Starting the SAP System

1. Log on in UNIX as a user with SAP administrator authorization (adm).

1. Enter the command startsap [DB|R3|ALL] from your home directory. The following applies to this command:

¡ DB starts the database system

¡ R3 starts the instances and associated processes of the SAP System (using the sapstartprogram)

¡ ALL starts both the database system and the SAP System. ALL is the default value and can be left out.

2. After you have started the database and the central instance, you can perform other actions within the CCMS.

To check whether all application servers of an SAP System were started correctly, start the Alert Monitor (transaction RZ20) or the Overview of SAP Application Servers (transaction SM51)

Stopping the SAP System

1. Log on in UNIX as a user with SAP administrator authorization ( adm).

2. Enter the command stopsap [DB|R3|ALL] from your home directory. The following applies to this command:

¡ DB stops the database system

¡ R3 stops the instances and associated processes of the SAP System

¡ ALL stops both the database system and the SAP System. ALL is the default value and can be left out.

Starting and Stopping Instances
