RFC & SAP Performance

Hi,
We have a situation where Web Portal makes an RFC call. We are thinking about limiting the number of users that can log onto the portal simultaneously.
What are the performance issues related to maximum number of simultaneous calls to this RFC? If say 100 log into the site simultaneously, 100 RFC calls would be generated. Will there be any performance related issues?
Thanks

Hello,
Generally if data is structured properly,it should not create problems.
What causes problem for such RFC calls is amount of time SAP takes to respond .If you have RFC which is not wirtten in good way (for optimised performance) then SAP takes lots of execution time to return data back to calling application & that sometimes is an issue for users who would not like to wait for 30-40 seconds just to get some data based on which they will go ahead & decide further actions.
Hope this helps.
Thanks.

SOAP service /sap/bc/soap/rfc/sap does not exist

Hi!
I implement ABAP-Proxy to SOAP scenario.
For the receiver communication channel (SOAP Adapter) I need to put target-URL
http://<server>:8000/sap/bc/soap/rfc/sap/BAPI_MATERIAL_EXISTENCECHECK?sap-client=200.
Unfortunately the URL cannot be displayed in brwoser.
I also could not detect the appropriate SICF service sap/bc/soap/rfc/sap under tcode SICF.
Can some one help me to solve this problem?
Thank you very much!

SAP Performance tuning

What measures shall we take if it is needed to performance tune the SAP Server. It is getting too slow. It will be helpful if someone can send me some link about SAP Performance tuning, not ABAP performance tuning.
Regards,
Subhasish

The SAP Servers can be slow because of many reasons:
1. The Table Consistency: The tables should be consistent. A consistency check should be done regulalrly.Better would be using DB13 so that it can be scheduled in appropriate days.
2. One major reason that I have found in recent times is the amount of authorizations that might be available to the users of the sytem. If all the users have a high volume of authorization objects in their user master buffer, then the response time becomes sluggish.This is true for most of the dev boxes that allow almost any amount of authorization for users and have a low RAM size.
3. Also you might be intrested to check your network consistency. If you are accessing your servers from home with a wireless connection of 16kbps, you might want to configure your logon pad for such a crappy connection.
Most of the BASIS performance tuning tasks such as ST04, STAT, ST02 and DB12 should be carried out too just to investigate furthur.
Hope these were a few helpful tips.
Peace be with everybody

Hi,
Have you gone through this ,We already have the discussion on this .

BTW , As you say, you are going to create the Milsetsone what is your reference is it WBS element and project definition or network , How are you planning to bring the reference data from the legacy system [ As example the WBS element against which the Milestone s are craeted] into SAP . Becuase as far as i know milestones area attached with project definition and then further down to WBS element so you need to bring the Project definition + WBS element to change create the milsetone .

SAP Performance Testing - Manual or Automated?

Our organization is attempting to develop a regular performance testing effort. Everything wehave read points to using a tool, such as LoadRunner, to do performance testing. However, we're just starting and simply want to baseline several transactions, jobs, programs, etc (less than 30 items). We have tools to monitor the backend results and grab metrics, but no tools to automate the testing itself. Does anyone do their performance testing manually? What are some advantages to doing this?

Hi Yogi,
I think HP LoadRunner is one of the best tools for SAP performance testing. I did it for many years. It is now included with Solution Manager. Here is the link for for HP Mercury regarding performance testing.

SAP Performance

Hi Friends,
I would like to know how to chek SAP performance. How can we check SAP performance what T Codes we use to check the performance. what to check with the T-codes please let me know.
If performance is bad then where we need to check please let me know,
Thanks,
praveen

Hi Praveen,
Let me add some key steps to analyze performance of your system (e.g. R/3 system).
Start with the transaction ST03N.
*St03N:* Try to find the Avg. Response time for the Dialog task for all the servers and instances.
SAP Threshold for this is 1000ms. If you see >1000ms, which means your system is having some issues and some tuning is needed.
The parts of response time are:
DB time (SAP threshold is 40% of Avg. Response time)
CPU time (SAP threshold is 40% of Avg. Response time)
Wait time (SAP threshold is 10% of Avg. Response time)
GUI time (200ms.)
Roll wait time (200ms.)
Roll in time(20ms.)
The other times are which are not direclty part of response time:
Processing time (<2*CPU time)
1. DB time is high, which mean above SAP threshold:
ST04 (database monitor):
Lookinto Database buffer quality (SAP Threshold is 94%)
If this Database buffer quality is less than the SAP threshold try to increase database buffer cache size.
Shared pool size (generally from 600MB to 2GB depending on the size of the database)
In the same ST04 screen look for user/recursivecalls, if this factor is >20 then we can say thre are some expensive SQL statements which in need of tune. Analyse the top expensive statements. possible reasons of expensive SQLs are i) incorrect index access (Solution is create new index or reorganize the index)
ii) high table size (Soluiton is archiving some of the old entries)
2. If CPU time is high, which mean above SAP threshold:
ST06 (OS monitor):
Go to Detailed Analysis Menu--> Top CPU , check existence of Non-SAP (external) programs by sorting by CPU time.
Try to run these external programs in offline hours.
ST02 (Buffer Monitor):
Check for any swapping happening in all the buffers. If you observe high swapping for any buffer, increase the size of the buffer.
Here program buffer (PXA) is important buffer.
3. If Wait time is high, which mean above SAP threshold:
SM50 (Workprocess Monitor):
Look for all the configured work processes are in Waiting or Running state.
If all the wotk processes are running state, then increase the number of Dialog work processes.
SM66 (Global work process Monitor):
This monitor will help to analyse the total work processes configured in all the servers and instances.
4. If GUI time is high, which mean above SAP threshold:
ST06> Detailed Analysis Memu> LAN check by ping (4096 bytes for all the presentation servers)
This will help to findout network performance. If you see high Avg. time or Loss time for any presentation servers from the result, which means there are some settings in need of change for that presentation server.
SE38-->execute PROFGEN_CORR_REPORT_5 report.
from the output check if any user assigned with >1000 user menu nodes.
SAP threshold is 1000 menu nodes.
5. If Roll Wait time is high, which mean above SAP threshold:
Please review SAP Notes 8963 and 99584. Roll wait time with a high value is a first indication for a slow network between the GUI and the CRM instance. Please check connections between the frontend and your servers. You can monitor relatively high average roll wait time, high average frontend network time per dialog in transaction ST03N. Please check your network with network vendor.
Specifically, check the network between application servers and fronts by running NIPING test as per SAP Note 500235.
If you need any further information feel free to reply me.
Thanks and Regards,
Pavan Kumar Gali.

Besides LoadRunner, any other SAP Performance Test tool?

Hi, Dear All:
I'm doing some planning for the SAP performance test. But our budget is very limited. It seems my company could not afford LR. LoadRunner took over 95% of this market. Beside LR, I heard Worksoft Certify is another option. Is there any other tool or open source tool?
Thank you all so much in advance.

Hello,
If you are looking for simulating load using minimalist tools, a crude way to do this would be configuring Ecatt scripts and running them from multiple machines
But I think it doesn't work for web based transactions.

RFC's for SAP Performance data

I am in the process of developing a Performance Monitoring System for SAP in Java.
The requirement is to fetch the performance metrics from SAP in a Java application. I know there are some RFC's available in CCMS module. But the customer is not interested in CCMS module.
Could anyone let me know whether there are any RFC's available in SAP for extracting performance data other than CCMS?
If anyone had come across this situation, please let me know.
Thanks,
Vijay

Hi,
there are severam methods for estimating av. response time after the upgrade, for the beginning you coud try to estimate
hardware (cpu, memory, disks) just to keep those resp. times on the same level. Use the followin notes:
089305, 0113795, 0178616, 517085 .... until you get note for your target release
then you have to add all deltas, and you will know the whole delta between releases.
For the first estmation of time change you can count it by using coeffition as deltas, example delta cpu = X
resp. time after upgrade = X * current resp. time
This formula gives you only impresion on resp. time, not precisse measure. Better calculation is simply
by calculating current system in saps, than using delta (for cpu) You can estimate required number of saps for target release, and X=req. SAPS for target/ current SAPS (btw. take for the estimation number of SAPS for current HW target release only, don't use the number of SAPS for 46C!), and again:
after upgrade = X * current resp. time
Please remember, thera are much better ways to estimate res. times, but it means detailed analysis of the system load, it can't be given as gold rule
Kind regards,
Mirek

Scenario XI - HTTP - Webservice - XI - RFC - SAP R/3

Hi,
i have the scenario:
Sending request to an Webservice per HTTPS and catch the response. This is working fine. In transaction sxmb_moni i can see the answer as XML.
I have implemented the scenario response from webservice mapped into RFC-Function and send into SAP R/3. But i have to run this manuell! How can i run this automatically after getting the response from the Webservice.
Thanks for any answere,

SAP R/3(Client100 using Proxy)---- XI----- RFC(SAP R/3 client 222) Scenario

Hi all,
I have the requirement to work on SAP R/3 ( with client 100 by using outbound Proxy)-->XI--->RFC(R/3 Client 222).
i have done IR & ID Part. Now i am going to create Report in R/3 side (100 client). But, it is synchronous, i am getting so much confusion. Please help me how to write the code for it.
The RFC is BAPI_EXCHANGERATE_GETDETAIL.
I created Request message, Response message for sender.
The message mappings are as follows:
For Request:
Sender Request------> BAPI Request
For Response:
BAPI Response---->Sender Response.
Interface mapping
Sender Interface---->BAPI.
Request message contains the fields:
Rate Type,
SourceCurrency,
TargetCurrency,
Response Message contains:
Exchange rate,
FactorFromRatio
FactorToRatio.
Please try to understand this requiement and help me to write code for this.
Thanks in advance.
Regards,
Nagarjuna.

Hi Nagarjun,
If you look at the exporting and importing paramters of your Method EXECUTE_SYNC...
You would find the abap equivalent of your Message Type. Hence you know all the fields.
No it depends on the business Logic, or ratheer what the RFC is suppose to be requested for is filled in an an Input paramter to the Method.
This can be an IDOC To, in that case your MT should be similar. Fill in the transmiaaion IDOC values.
OR you can Actually harcode the values, make your Itab, and send it across ( as this is just for test purposes )
Hope this helps.

Abhishek

RFC( SAP R/3) to XI to 3rd party Application

Hi All,
we have an 3rd party application to which we want to send some data from R/3. We are using XI as the middleware.The process has to be triggered from R/3 side. We are not using Idoc's here. We are planing to use the RFC through which the data transfer has to be done.
We are creating a BAPI with import, export and tables parameters.Basically the RFC is in SAP R/3 System.We need to send the data in the table to XI.
In this case how the RFC destination has to be created and how the RFC to be called in the R/3 system to export the Data to XI system.
Answers are highly appreciated.
Thanx and Regards,
Durga.

Hi,
<i>>>>In this case how the RFC destination has to be created</i>
Check this blog by Michal it shows you step by step
/people/michal.krawczyk2/blog/2005/03/29/configuring-the-sender-rfc-adapter--step-by-step
<i>>>>how the RFC to be called in the R/3 system to export the Data to XI system.</i>
Hope you are aware of normal way of calling function
CALL Function "FM Name"
Export
Tables
in this case the RFC should be called as follows
CALL Function "FM Name" destination <SM59 Destination>
Export
Tables
The above is for Sync call and if you want to make a Async call that is you are not expecting any reponse from the target then
CALL Function "FM Name" IN BACKGROUND TASK destination <SM59 Destination>
Export
Tables
Thanks,
Prakash

Java JCo SAP XI RFC SAP R/3 6.C ... Unicode issue

Hello,
My scenario is very simple. I'd like to connect a Java program to a SAP R/3 (MDMP) for RFC calls (in both direction), using SAP XI (some of the RFC calls will redirected to some other systems). I use SAP JCo v2.1.8 and tried with Java 1.4.2_09 and Java 6.0.
It works well when the Java program is calling a function module, but when SAP R/3 is doing it, the returned texts looks like: S#A#P# #J#C#o# #v#2#.#1#.#8# #(#2#0#0#6#-#1#2#-#1#1#)# (the text should be SAP JCo v2.1.8).
It looks like an issue with Unicode. Although I didn't check the Unicode checkbox in the RFC sender adapter (the RFC receiver one doesn't offer the possibility to specify unicode or not).
Do anyone have a solution ? Is it a code in the Java program or something to set in SAP XI / SAP R/3 ?
Thanks in advance for your help.

This is a workaround solution. In the case of this prototype it is ok, but the final plan is to migrate a web based application. It was directly connected to one SAP R/3, but now we would like to connect it to SAP XI because a few RFC calls will be re-directed to some other systems, but the majority of them will we'll still be sent to the SAP R/3. We don't want to make development on this part for cost reason (and time). Plus on some text there are the "#" character that is legitimate.

RFC- SAP XI- PLAINHTTP SYNC causing Problem

Hi,
I am trying to set up a Scenario that sends a synchronous
Request from SAP via RFC to a selfwritten HTTP Receiver,
using the Plain HTTP Adapter. I want to receive my request
by my server (that part works allready)and send my response through the same connection back.
Everytime I send something back I get an

Please help, I am new to that HTTP Stuff...
Kind regards
Daniel

Hi Robin and all,
maybe I need to make that more clear,
I build a complete synchronous scenario in ID,
RFC -> XI -> PLAINHTTP everythings works fine until my
Java program catches the response message,
when I try to use the still open connection (through
that Xi has allready sended my the request) to put the
XML-Message (Response message type referenced at the
response tab of my synchronous interface)back, I get a
time out in XI.
1. Question: Can I use the socket object in my Java
progtam to send my response directly back
2. If yes what besides the XML message payload is needed
3. Will I have to reference the incoming Message ID to
make clear my message is the synchronous response?
Thanks for helping me with that.. (answer will be rewarded)
Daniel
with a synchronous Interface on inbound (HTTP) side and
I catch
the sendes request message from HTTP Plain Adapter in my
Java Program (socket server object),
I keep the connection open and I through the same
connection the Response Payload (which is
the XML representation from my Response - Message Type
as defined in XI), looks like this:

Visual Basic RFC SAP no-unicode. Latin2 Caracteres are converted in '#'

Hi,
I are inserting data in Z SAP tables from a Visual Basic Script.
I are doing a RFC call.
The problem is that the data type text aren´t iserting correct when its are Latin2 caracteres.
Example:
Text in Visual Basic: "Prevozni strou0161ki-železniu0161ki"
But when theRFC function inserts the data in SAP, SAP shows "Prevozni stro#ki-#elezni#ki".
Could somebody help me??
thanks in adavanced,
Javi

Thanks for your answer.
But i din´t solve the problem.
I changed the encoding to UTF-16 and ISO-8859-5 but the caracteres are inserting bad yet :(.
I'm debugging the visual basic code and I can see that the text is correct in Visual Basic, but after it is incorrect in SAP.
Too, I'm inserting the value directly in visual basic sourcecode:
T_BAPI_P.Value(index, "TXZ01") = "Prevozni strou0161ki-železniu0161ki NOVO"
But the result is the same.
SAP shows "Prevozni stro#ki-#elezni#ki NOVO".
I have seen that in the transaction SM59 you can specify if the RFC conexion will be UNICODE.
The SAP system that i am working isn´t unicode, then it can not the tag to especificate this in SM59.
Could it be the problem that the SAP system isn´t unicode??
sorry, for my English's low level.
Thanks in advanaced for all yousr answer!
