SAP Profiles: Default Profile, Start Profile ans Instance Profile

What are SAP Profiles (SAP Basis System Profiles)

SAP Profiles (System 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.

SAP Profiles

  • Path: <SAPMNT>\<SID>\SYS\profile\
  • Example:D:\usr\sap\DEV\SYS\profile\
  • Only the Central Instance Host file system contains the SAP 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 SAP 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

SAP 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

SAP 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
  • Management of Memory Buffers
  • Ports
  • Db Home etc.
SAPSYSTEMNAME = DEV
INSTANCE_NAME = DVEBMGS00
SAPSYSTEM = 00
rdisp/wp_no_dia = 5
rdisp/wp_no_btc = 1
rdisp/wp_no_vb = 1
rdisp/wp_no_vb2 = 2
rdisp/wp_no_enq = 1
rdisp/wp_no_spo = 1
SAPGLOBALHOST = CHALAKI
PHYS_MEMSIZE = 1223
DIR_TRANS = D:\usr\sap\trans
icm/server_port_0 = PROT=HTTP, PORT=8000, EXTBIND=1
DIR_ORAHOME = D:\oracle\ora92
