Instance Profiles

Definition

Instance profiles provide an application server with additional configuration parameters to complement the settings values from the default profile. Typically, these parameter settings adapt the instance according to the desired resources. They also define the available instance resources (main memory, shared memory, roll memory and so on), and how to allocate memory to the SAP application buffers.

Below is a typical instance profile:

#.*************************************************

#.* Instance profile BIN_DVEBMG53 *

#.* Version = 000005 *

#.* Generated by user = BLOCHING *

#.* Date generated = 04.08.1995, 11:10:35 *

#.*************************************************

INSTANCE_NAME = DVEBMG53

SAPSYSTEM = 53

SAPSYSTEMNAME = BIN

abap/buffersize = 40000

abap/programs = 600

ipc/shm_psize_10 = 15000000

ipc/shm_psize_14 = 0

ipc/shm_psize_17 = 0

ipc/shm_psize_18 = 0

ipc/shm_psize_19 = 0

ipc/shm_psize_40 = 17000000

rdisp/PG_MAXFS = 4096

rdisp/PG_SHM = 1000

rdisp/ROLL_MAXFS = 16384

rdisp/ROLL_SHM = 200

rdisp/btctime = 60

rdisp/wp_no_dia = 5

rdisp/wp_no_enq = 1

rdisp/wp_no_vb = 1

rdisp/wp_no_vb2 = 1

You can choose any name for an instance profile. The SAP naming convention is as follows: _ or __ .

C11_DVEBMGS12.

C11_DVEBMGS12_hs0011

To start application servers on several computers using identical parameter settings, you can use a single instance profile. It is generally not necessary for each application server to have its own instance profile. Instance profiles are also called system profiles.
