SAP R/3 System Profiles - Default Profile, Start Profile and Instance Profile

What are SAP Default, Start, Instance Profiles?

• Profiles contain parameters that specify how to startup an instance and how to setup the various variables that define the way the SAP instances and system work.
• Path: <SAPMNT>\<SID>\SYS\profile\
• Example:D:\usr\sap\DEV\SYS\profile\
• Only the Central Instance Host file system contains the profiles for all instances.
• Dialog/regular instance hosts do not have any profiles stored on them.
• If you have N instances on a SAP system (sharing the same SID) you will see 2*N+1 profiles files and their corresponding backup files if any in the SYS/profile folder.

Default Profile

Name: DEFAULT.PFL Contains global parameters that apply to all instances in the SAP R/3 SID such as:

SAPSYSTEMNAME = DEV
SAPDBHOST = CHALAKI
rdisp/mshost = CHALAKI
rdisp/sna_gateway = CHALAKI
rdisp/sna_gw_service = sapgw00
rslg/collect_daemon/listen_port = 37
rslg/collect_daemon/talk_port = 13
rdisp/bufrefmode = sendon,exeauto
ms/http_port = 8100
dbs/ora/tnsnames = DEV

Start Profile

Contains starting parameters for the instance. Each instance will have its own start profile.
Naming Convention: START_<INSTANCE NAME>_<Host Name>
example:

START_DVEBMGS00_CHALAKI
Contents: SAPSYSTEMNAME = DEV
INSTANCE_NAME = DVEBMGS00 
SAPSYSTEM = 00
SAPGLOBALHOST = CHALAKI _DB = strdbs.cmd
Start_Program_02 = immediate $(DIR_EXECUTABLE)\$(_DB) DEV _MS = msg_server.exe
Start_Program_03 = local $(DIR_EXECUTABLE)\$(_MS) pf=$(DIR_PROFILE)\DEV_DVEBMGS00_CHALAKI _DW = disp+work.exe
Start_Program_04 = local $(DIR_EXECUTABLE)\$(_DW) pf=$(DIR_PROFILE)\DEV_DVEBMGS00_CHALAKI

Instance Profile

Contains instance specific profile data. Each instance will have its own start profile. Naming Convention: <SID>_<INSTANCE NAME>_<Host Name> example: DEV_DVEBMGS00_CHALAKI

• Management of work processes
