hi ever body
why dialog process goes in to priv mode many time when our functional consultant running tcode FAGLB03 G/L ACCOUT LINE ITEMDISPALY G/L view ....i am using windos 2003 with sap ecc 6.0 having 4 gb ram related parameter is here plz guide me....
1. ztta/roll_area 15000000 Byte
2. ztta/roll_first 1 Byte
3. ztta/short_area 3200000 Byte

Hi Anuj,
It is not so easy to answer your question just by seeing one work process memory utilization of single sample. If you see the work porcess used more memory when it is running fine than in the priv mode. this may be due to the occupency of memory by other running applicaitons at that time. However you have memory issues and memory related parameters are not configured.
I suggest you to use PHYS_MEM parameter and remove all memory configuration parameters from your instance profile so that zero memory administration is enabled as yours is windows2003 operating system.
Answer to your question: Why work process go to priv mode?
Memory will be allocated to WP in different stages.
1. Memory will be allocated from local memory defined by ztta/roll_first parameter
2. Memory will be allocated from Extended memory (initial extend memory size is defined by parameter em/initial_size) and allocation has limits.
a) Memory can be allocated from extended memory only if required memory is available in the system and is less than the values mentioned by the parameter ztta/roll_extended and size of extended memory.
3. If allocation specified in point 2 is not enough for execution it uses all local memory specified by ztta/roll_area
If still not memory is not sufficient it is forced to use heap memory to complete execution and WP enters into PRIV mode.
In case you cannot resolve issue i request you to run early watch or contact SAP
Thanks,
Kiran.

Hi Guys,
I have questions regarding switching to 64-bit. I am running 32bit ECC5 production system for quite a long time,and I got all my business data in it.How do I switch to 64-bit with all this data?
There are couple of options coming to my mind,enlighten me how it is actually done?
PLAN A
Get a new hardware ,install 64-bit SAP (with same support pack level),then do a client copy from 32-bit old production server to this new 64-bit.
Question here is :a) Is it possible to do a remote-client-copy from a 32-bit SAP to a 64-bit SAP?
b) Assuming it is possible,how can I register the system in SAP?Do I need to intimate SAP and get a new license for 64-bit,or the old 32-bit license would be sufficient to generate a license key. I think we need to renew the license contract-Correct me if I am wrong
c)At the same time,will I be able to register two production systems,one is 32-bit and another one is 64-bit ?
PLAN B
Do a system copy- creating and export using 32-bit installation master and importing that with 64-bit installation master-Will it work?
PLAN C
Do something like OS-DB migration and generate a migration key- Is it the solution for migrating from 32-bit to 64-bit?If so wont it be required to use the same Installation master for doing the export and import?
Thanks and Regards
Syam

check SAP note 88416, setup PHYS_MEMSIZE and delete memory-related parameters that you see in the middle of the note.. .then, restart SAP.
have you setup /3gb and /pae ?

Thanks sir for reply but here i want to ask about that parameter if you can guide ...
ztta/roll_extension =500000000 Byte is it ok or should i increase...
also
abap/heap_area_dia= 5635068480 Byte
abap/heap_area_nondia =5635068480 Byte
abap/heap_area_total= 1500000000 Byte also i want to ask about this parameter should i also increase it to equal of abap/heap_area_dia & abap/heap_area_nondia.
please guide me .
With Regard
Anuj
>The 32 bit era is very quickly coming to an end for SAP software !
new SAP software releases demand more memory requirements because of its complexity (ABAP+JAVA etc..etc..) and enhancements. SAP do not recommend to run your productive netweaver instances on 32-bit system because of its address space limitations...
set /3GB option for windows as others mentioned.
optimize programs to see whether large data set selection can be avoided.
Check what is the extended memory usage when the process is going to heap. If this is because of unavailability of extended memory then you can increase the amount of physical memory and adjust the extended memory parameters (set PHYS_MEMSIZE and make em/initial_size = PHYS_MEMSIZE value)
This may give you some relief, but not a good solution in your case...
Migrate to 64-bit based environment as a permanent solution..
Thanks Manoj
I CALULATE THE TIME TAKEN BY THAT T-CODE
T-code=FAGLL03
Steps=1.097
Total Response Time in second=2.427
Average responce time/dialog step in ms=2.212,5
T CPU time in second=1.952
Average CPU time in second=1.779,1
Total DB Time in second=233
Average DB Time per dialog step in ms=* 212,8*
Total WaitTime in second=5
Average WaitTime per dialog step in ms= 4,3
Sequential Reads=7.573
Total Seq. Read Time in second=231
Accesses(No of direct read )=127.327
Total time for direct read in second =3
% CPU~=* 80,4*
% DB Time=9,6
% DB Proc.= 0,0
Request data KB=133.082
and
PHYS_MEMSIZE = 2000 but
em/initial_size_MB =1200
so should i increase em/initial_size that parameter to equal of PHYS_MEMSIZE.
please also guide me how can i check that how much extended momery is used by FAGLB03.
my total ram is only 4 gb
that is my processor
3.40 gigahertz Intel Pentium 4 (2 installed)
16 kilobyte primary memory cache
4096 kilobyte secondary memory cache
and about OS
Windows Server 2003 Enterprise Edition Service Pack 1 (build 3790)
and about system model
HP ProLiant DL380 G4
hi Manoj
you told me
you can increase the amount of physical memory and adjust the extended memory parameters (set PHYS_MEMSIZE and make em/initial_size = PHYS_MEMSIZE value)
when wprk process is in running condition
Roll In = 2
Roll Out = 1
Roll = 212.992 (Bytes)
Page = 122.880 (Bytes)
Memory (Total) = 387.791.892 (Bytes)
Memory(Total Private) = 138.197.600 (Bytes)
Memory (used) = 380.464.448 (Bytes)
Memory (Max. Transaction) = 387.779.952 (Bytes)
Memory (Max. Dialog Step) = 387.779.952 (Bytes)
when work process goes in to PRIV mode
memory take by it
Roll =212.992 (Bytes)
Page = 868.352 (Bytes)
Memory (Total) = 210.102.452 (Bytes)
Memory(Total Private) = 156.306.288 (Bytes)
Memory (used) = 202.775.008 (Bytes)
Memory (Max. Transaction) = 387.779.952 (Bytes)
Memory (Max. Dialog Step) = 210.091.632 (Bytes)
and i an having
PHYS_MEMSIZE = 2000 but
em/initial_size_MB =1200
so should i increase em/initial_size that parameter to equal of PHYS_MEMSIZE
so should i increase it or not also i send you time taken by That tcode .what did you find in that CPU time is more , so what is reason bheind that...
waiting for your reply..
With Regards
Anuj

Check what is the extended memory usage when the process is going to heap
i checked thrugh sm66 when work process is in PRIV mode
Extended Memory Bytes = 224735536
Heap Memory Bytes = 167511664
while having
em/initial_size_MB =1200 MB
ztta/roll_extension = 500000000 Byte
abap/heap_area_dia 5635068480 Byte
so which parameter should i increase
