SAP ERP System - slow system

147 Views

Hello,

Some weeks ago we migrated our SAP systems (ERP 6.0 with SAP_APPL=18; SAP_BASIS=28) to a new platform (the old platform = Windows Server 2003 (x64) with MS SQL Server 2005) Windows Server 2012 (x64) with MS SQL Server 2012.

But we don´t know why, but most users complain about the SAP system performance, they tell us that is slow!

The server has 12Gb of RAM memory and 21.5Gb of SWAP.

I checked the ST02 and I see the following values:

I also checked the RZ10 (instance SAP profile):

icm/server_port_0 PROT=HTTP,PORT=80$$

zcsa/installed_languages DEP

is/SMTP/virt_host_0 PROT=SMTP,PORT=0

zcsa/system_language P

zcsa/second_language E

ssf/name SAPSECULIB

abap/heaplimit 100000000

ztta/roll_area 20000000

abap/buffersize 900000

SAPSYSTEMNAME NEP

SAPGLOBALHOST SAPWP01

SAPSYSTEM 00

INSTANCE_NAME DVEBMGS00

DIR_CT_RUN $(DIR_EXE_ROOT)\$(OS_UNICODE)\NTAMD64

DIR_EXECUTABLE $(DIR_INSTANCE)\exe

sec/libsapsecu S:\usr\sap\NEP\DVEBMGS00\exe\sapcrypto.dll

ssf/ssfapi_lib S:\usr\sap\NEP\DVEBMGS00\exe\sapcrypto.dll

rdisp/wp_no_dia 10

rdisp/wp_no_btc 3

ms/server_port_0 PROT=HTTP,PORT=81$$

rdisp/wp_no_enq 1

rdisp/wp_no_vb 1

rdisp/wp_no_vb2 1

rdisp/wp_no_spo 1

ssl/ssl_lib $(DIR_EXECUTABLE)$(DIR_SEP)$(FT_DLL_PREFIX)sapcrypto$(FT_DLL)

zcsa/db_max_buftab 8000

Tell me one thing, how can I check which memory that is reserved for MS SQL Server database? I believe that value, on SAP system, the memory that is reserved for SAP system is the value that is set in parameter PHYS_MEMSIZE, which is by default in this moment 12287 (12Gb), which is the same RAM memory of server.

I don´t know what´s happen here... can you tell me with your own experience and give some advices with the goal of improving system performance, if there are some problems/errors, in your opinion, with the above values. Can you make me some recommendations, what I need to do to improve the performance of this SAP system?

Kind regards,

samid raif
