Start Profile

Start Profile

Purpose

When you start an R/3 instance on a host, the start profile defines which R/3 services are started (message server, dialog, gateway or enqueue process. for example). The startsap program is responsible for starting these service processes, and it uses a start profile to begin the startup process.

The processes that can be started include:

Application server

Message server

SNA Gateway

System log send demon

System log receive demon

Apart from the general profile parameters, such as the name of the R/3 System ( SAPSYSTEMNAME ), instance number ( SAPSYSTEM ) and name of the R/3 instance ( INSTANCE_NAME ), the only parameter names that are permitted in a start profile are:

Execute_xx (xx = 00-99) : To start operating system commands, which prepare the R/3 System start. For example, you can use this parameter to start the SAP related database or to set up links to executables on UNIX platforms.

Start_Program_xx (xx = 00-99) : To start an R/3 instance, for example, on an application server.

Stop_Program_xx (xx = 00-99) : To start an operating system command or SAP program after the R/3 instance was stopped. For example, the halting or removal of shared memory areas that were used by the R/3 System.

The number xx defines the execution sequence. The programs specified in Execute_ parameters are executed before the programs listed in the Start_Program parameters. After the SAP instance has been stopped, the programs specified in the Stop_Program parameters are started. Here is an example of a start profile used to start a message server, an application server and an SNA gateway:

#.***************************************************************
#.* Start profile START_DVEBMG47
#.*
#.* Version = 000003
#.* last changed by = WATT
#.* last changed on = 21.03.1995, 15:05:19
#.***************************************************************
SAPSYSTEMNAME = K11
INSTANCE_NAME = DVEBMG47

#----------------------------------------------------------------
# start message server
#----------------------------------------------------------------

_MS = ms.sapK11_DVEBMG47
Execute_01 = local ln -s -f $(DIR_EXECUTABLE)/msg_server $(_MS)
Start_Program_01 = local $(_MS) pf=$(DIR_PROFILE)/K11_DVEBMG47

#----------------------------------------------------------------
# start application server
#----------------------------------------------------------------

_DW = dw.sapK11_DVEBMG47
Execute_02 = local ln -s -f $(DIR_EXECUTABLE)/disp+work $(_DW)
Start_Program_02 = local $(_DW) pf=$(DIR_PROFILE)/K11_DVEBMG47

#----------------------------------------------------------------
# start SNA-Gateway
#----------------------------------------------------------------

Process Flow

To run a program on the local host, place the word ‘ local ’ in front of the relevant parameter value:

Execute_00 = local sapmsesa 53 remove

To execute a program on a remote host, place the host name in front of the parameter value.

Execute_00 = hs0011 sapmsesa 53 remove

You can choose any name for a start profile. The start profile files generated by SAP are structured as follows: START_<instance name> or START_<instancename>_<hostname> .

START_DVEBMGS53, START_DVEBMGS53_hs0311

To start the same SAP service processes on several hosts, you can use a single start profile. Each R/3 instance does not have to have its own start profile.
