Starting and Stopping SAP Systems and Instances Using Commands (Unix) You can start and stop SAP systems and instances using the startsap and stopsap commands.You can use command line options to specify these commands. Command line options are available in

new style or old style.Using New Style for Command Line Options and ParametersUsing new style, the syntax is as follows:stopsap | stopsap [-t | -task ] [-i | -instance ] [-v | -vhost "[ ]*"][-c | -check] [-h | -help] [-V | -VERSION] [-C | -checkVHost]

Example

If you want to start an ABAP or dual-stack (ABAP+Java) central instance DVEBGMS00 that has the virtual host names cic11 and cic12, enter the following commands :startsap-t r3 -i DVEBGMS00 -v "cic11 cic12" If you want to start a Java central instance JC00 that has the virtual host names cic11 and cic12, enter the following commands :startsap -t j2ee -i JC00-v "cic11 cic12"

End of the example.

The following command line options and parameters are available:

Using Old Style for Command Line Options and ParametersUsing old style, the syntax is as follows:stopsap | stopsap [db|r3|j2ee|all|check|startupsrv] [] []

Example

If you want to start an ABAP or dual-stack (ABAP+Java) central instance DVEBGMS00 that has the virtual host names cic11 and cic12, enter the following commands :startsap r3 DVEBGMS00 cic11 cic12 If you want to start a Java central instance DVEBGMS00 that has the virtual host names cic11 and cic12, enter the following commands :startsap j2ee JC00 cic11 cic12

End of the example.

Prerequisites Make sure that you have logged on to the physical host of the SAP system instances as

user adm. Make sure that the host names defined in the DNS server match the names of the SAP

system instance hosts. In particular, keep in mind that host names are case-sensitive. For

example, if the names of the SAP system instance hosts are in upper case, but the same host

names are defined in the DNS server in lower case, starting and stopping the system does not

work.

If you want to use startsap or stopsap (for example, in a script) and require the fully qualified name of these SAP scripts, create a link to the startsap script in the home directory of the corresponding user.

You cannot use startsap or stopsap commands in a switchover cluster environment. Therefore in a high-availability (HA) system you must use the failover cluster software of your HA partner to start or stop instances running on the switchover cluster.

You cannot use startsap or stopsap commands to start or stop database-specific tools. For more information about how to start or stop database-specific tools, see the database-

specific information in this documentation and the documentation from the database

manufacturer.

Make sure that no SAP instance is running before you execute stopsap on a standalone database server. No automatic check is made.

When you use stopsap in a Multiple Components in One Database (MCOD) system with two central instances, only one central instance and the database are shut down. Therefore, you must first stop the other SAP system or make sure that it has already been stopped.

ProcedureStarting an SAP System

If you want to start all SAP system instances running on the same host, execute the

following command:

New style: startsap or startsap -t allOld style:startsap or startsap all If you want to start SAP system instances separately, enter the following command:

New style:startsap -t r3|j2ee -i [-v ""]Old style:startsap r3|j2ee []Make sure that you adhere to the following sequence when starting the instances:

ABAP system:1. Database instance

2. Central instance

3. Dialog instances (if available)

Java system: 4. Database instance

5. SCS instance

6. Central instance

7. Dialog instances (if available)

Dual-stack (ABAP+Java) system: 8. Database instance

9. SCS instance

10. Central instance

11. Dialog instances (if available)

Stopping an SAP System

If you want to stop all SAP system instances running on the same host, execute the

following command:

New style: stopsap or stopsap -t allOld style:stopsap or stopsap all If you want to stop SAP system instances separately, enter the following command:

New style:stopsap -t r3|j2ee -i [-v ""]Old style:stopsap r3|j2ee []Make sure that you adhere to the following sequence when stopping the instances:

ABAP system:1. Dialog instances (if available)

2. Central instance

3. Database instance

Java system: 4. Dialog instances (if available)

5. Central instance

6. SCS instance

7. Database instance

Dual-stack (ABAP+Java) system: 8. Dialog instances (if available)

9. Central instance

10. SCS instance

11. Database instance
