BO Sizing - 3 Tier

Hi,
We are building a new BOE server for Crystal reports,WebI, and Dashboards. For all SAP instances we use distributed model and we want to use the same for BOE. After sizing on quicksizer I see that my system would be S or M with 80 Gb of RAM. My question is - I want to install the systems in 3 Tier. Is this possible? I mean, CMS and BO applications on one, Tomcat on another, and the Database (SQL) on another. Is this possible? I have seen it mostly on a single central instance and want to know from people who may have used it this way. I have seen some blogs for splitting in 2, but havent seen in in 3. Please let me know your thoughts. thanks in advance..

Jim,

BW Sizing with multiple app. instances on Oracle 10g

Hello folks,
I have a few confusions to clarify as i am engaged in BW sizing exercise. Customer has a huge environment with multitera bytes of data and its expected to grow in size and also # of users too and they have multiple BW app instances (NW 7.0) running on Oracle 10g. Its a RESIZING exercise for post go-live in Production solutions and also maybe Delta Sizing for new expected growth.
I went thru all the docs on SMPsizing but wanted to clarify some stuff from folks who have worked on this kind of environment. I did not find per say "BW Sizing" document for NW 7.0, all i found was something about BW 3.0 (http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/10e7e662-dc1c-2a10-d78c-a187d1a25f80) and also another document ASAP for BW sizing ver 3.1 / 2004. h hints to calculate Disk space, memory and Cpu. Will these assumptions or parameters .
Questions:
Do the parameters and assumptions in the above lets say about # of bytes to SAPs would be applicable to the environment i am working on i-e NW7.0?
For Space sizing to calculate size of InfoCube there is something called 2X disk space requirement of the largest fact table or at least 10GB (PSAPTEMP)....DO I have to add that to every cube for which i am calculating space size?
In CPU Data Staging part there are assumptions based on BW Benchmark like rec/hour/job= 750000, SAPS/batchjob= 350saps and then Maintenace Window = customer input...is this customer input is the window in HOURS when data load happens?
Also for same CPU Sizing Data staging #jobs={sum(delta upload)/maintenance window} / 75000....what is this delta upload consists of?
SAPS that come out from CPU query and from CPU staging , do i sum them up together and then find out Partner BenchMark# or deal with them seperately?
I only see SAPS BenchMark available for hardware partners to compare for ONLY 2-tier systems although environemnt i am working on is 3-tier, would it be still valid?
You help will be appreciated, anyone.
thanks.

Hi, Venkat, I hope you posted the same question in other Data Warehousing also.
BW sizing
We have a tool called Quick Sizer in service.sap.com and if you provide the information to that tool it will give the BW Hardware sizing, you add 20% buffer to the final figure.
You need to give the following information...
1. No. of users i.e 3 kinds of users.
2. No. of Records Per day with Line Items.
3. Loading Frequency.
4. No. of InfoCubes/DSO's, Master Data Objects.
5. Future enhancemts like that.
It is better you ask Basis people about Quick Sizer and ask the above points to your Business and Functional People.
Thanks

BPC NW architecture and sizing

Dear all,
    According to the master guide of BPC NW , there are 4 tiers in BPC system
Client tier
NET Web Server and Application Server tier
SAP NetWeaver Application Server tier
Database tier
I got some questions about the NET Web Server and Application Server tier
1. Can we install the NET Web Server and Application Server for Dev & QA system on the same hardware box?
2. How do we do the sizing for NET Web Server and Application Server?
    We have around 300 users who might upload data & checking report.
3. If our users increase in the future, can we add AP servers of NET Web Server and Application Server for load balancing?
4. What the purpose of NET Web Server and Application Server?
    According to the master guide, it's responsible for web service , conversion and application services. But, any details of those services?
Thanks,
Jeff

Dear Jeff,
1. You can't run more than one BPC Application Server(.Net Service) in the same hardware( If you are using LPAR kind of configuration in IBM server you can install multiple OS in the same hardware)
2. You can add the more application server if the server is more loaded.
3. The Sizing of the application server depends on the no of users. Its almost equal to the BPC MS platform.
4. You can either use 32bit or 64 bit OS for the application server. If you use 32 bit Windows OS you can't use more than 4 GB, since 32bit OS limitation.Even if you add more than 4 GB, the 32 bit OS will not able to use entire memory.
5. NW SR3 onwards, SAP will not support 32 bit OS.
Hope you are bit clear about the 4 tier architecture.
Regards,
JP.

Proper server sizing for SPARC/Solaris to Intel/R migrations

Is there any collateral available concerning proper server sizing for customers migrating from SPARC/Solaris to Intel/RHEL? I was just asked by our account team that is working with a very large custormer in the pharma space.
My initial knee jerk was to refer them to the OEM but thought I'd look around in these forums first.
My searches have not returned any good results yet.

Hi Mike
the public SAP SD-Benchmark homepage ([http://www.sap.com/benchmark/|http://www.sap.com/benchmark/] -> SD two-tier results) gives interesting but very indirect sizing hints. There are several SAP SD-Benchmarks on SPARC/Solaris. I picked some of them:
[2008075|http://download.sap.com/download.epd?context=B1FEF26EB0CC3466320983FEDBEB2A47615DC8F24866B0B6870E95AA3589B515566F7A57D98961BB]: 24650 SD-User w SAP ERP 6.0 (2005 Non-Unicode) on SPARC Enterprise Server M9000 (32CPUs)
[2008062|http://download.sap.com/download.epd?context=40E2D9D5E00EEF7C974D9FC4D21DA80E794CB437BC196262799B27A2BB01B9D6]: 825 SD-User w SAP ERP 6.0 (2005 Non-Unicode) on SPARC Enterprise Server M3000 (1CPU)
[2008058|http://download.sap.com/download.epd?context=40E2D9D5E00EEF7CB82813BD3F95797BAEB80527B36EC026E03386D659E4DE48]: 7520 SD-User w SAP ERP 6.0 (2005 Non-Unicode) on SPARC Enterprise T5440 (4CPUs)
You'll probably have the hardware setup of your customer together with the system utilization. Check it with the Solaris/SPARC benchmarks on the public page and check for Intel Benchmarks as well. Make sure, that the SAP release is the same (with 2009 a new SAP release is mandatory for benchmarks -> numbers are not comparable to 100%).

Hannes

Sizing of WebLogic Cluster Servers

I have an application that needs to be implemented in BEA WebLogic 5.1 (
JSP, Servlet, EJB) and deployed on Solaris 8 talking to Oracle
8.0/Solaris (in clustered environment).
I am in the process of sizing the application. Following are some of the
basic sizing information:
No of users: 6000
Usage Pattern: High during evenings in US time zone
Concurrent users: 300
EJBs types: 200 entity and 50 session beans ( stateless), 4 stateful
session beans
State Per User: 2K
Database Tables: 100
No of screens: 80
Data Accessed per User Request: 20K
Cluster: Yes
No of Machines in Cluster: 2
Clustering Type: Recommended 2- tier ( with Web Server on a different
machine)
What kind of SUN machine should I be buying?
I mean, ES 220 or ES 450 ...or a higher end machines? What should be the
swap space, RAM, no. of processors?
Any existing documentation or specification will be very valuable.
Thanks,
Hari

Hi,
First of all weblogic server has ONLY one Admin Sever per Domian which should be used for administrative work, hence we cannot have have a backup of Admin server.
Weblogic Server Architecture
Yes, the best way is to use horizontal clustering as shown below where all the managed servers are in a cluster.
Machine-1
- Admin Server
- MS-1
- MS-3
Machine-2
- MS-2
- MS-4
HTTP Servers Architecture
Assuming you would be using Apache HTTP server, hence using weblogic Apache plugin you would be able to communicate with weblogic servers. In hhtpd.conf file you have to load the module and in if-module block you would have to give all the information about the weblogic server which would then try to connect with weblogic servers as well as will load-balance between them.
For more information check the below link for Apache HTTP server.
Topic:Installing and Configuring the Apache HTTP Server Plug-In

Database Memory sizing for BI Beans

We need to make a RAM sizing for a production enviroment for 200 users, how can i do it?
Thanks in advanced,
HABO

This needs to be broken down into two areas and by hardware and software requirements:
1) Database - the OLAP forum would be the best place to ask about specific requirements for the OLAP option. There is guidance on parameter settings for the OLAP option in the installation guide. In terms of hardware to support your proposed user community. In the documentation pack you might want to review the Data Warehouse and Performance Tuning guides.
2) Middle-tier/iAS - Oracle has an internal only utility that can be used to predict hardware requirements for a middle-tier server. Your account manage should be able to help you with this. In terms of tuning, please refer to the Oracle Application Server Performance Guide.
Hope this helps

Sizing for SAP BCM (Business Communication Management)

Hi All
We have to provide a server sizing to be used for SAP BCM (Business Communication Management) module which will be intergrated with SAP CRM and is to be used for call support. As far as we have reached, we require a Windows server and will host MS SQL database with an approx consumer data of 63 lacs consumers.
Please specify the sizing for this server
Thanks in advance
Lokesh

Sorry, forgot to ask how much physical memory you have on each host.
Let's split it to 2 topics.
1. For ECC, since OracleDB and non-unicode page which are the 2 major factors won't be changed, so I would think here we could just do a math, as long as host A has enough memory which is allocated for Oracle and ECC (extended memory) on host B to be added up.
2. For EP, memory tuning size is basically the same for HP JDK and SUN JDK, that each server node is allocated approximately 2.5GB RAM. Besides, 0.8-1GB RAM needs to be left for OS kernel. But in your case, host B is currently holding 200 users which is a big jump for host A(note: only active user quantity matters here).
That's fine if main physical memory is a little short for host A, utilizing multiple less powerful servers as 2nd tier application server to do the load balancing is also a solution with lower TCO.

SAPS in sizing Guide

Hi
Can you please help me to find out more details about processor in MDM sizing?
From CPU I got result: 6500 I do not know how can I find processor, can you help me ?
I found something here:
http://aroundsap.blogspot.com/2007/09/sap-hardware-sizing-and-benchmarking.html
but that is not exactly what I am looking for.
Many thanks for finding CPU type.
My result for RAM is 10 GB do you think that is correct, we have 8 repositories?
I think my calculation is correct - I just woult like to have others consultancy
Thank you in advance.
Have a nice day.

Hi ,
SAP periodically benchmarks different servers and indicates their SAPS. Visit:
http://www.sap.com/solutions/benchmark/index.epx
Select on the right under SD Benchmarks ->"SD two-tier results" (as NW MDM is more similar to a 2 tier architecture).
A table will open with all benchmarked server's SAPS results.
The list updates periodically.
You can download it to a text delimited file.
Hard to indicate regarding the RAM you received without having more details.
The calculation should be done for each repository on the server separately and then added up.
Generally, 10GB memory seems a resonable result.

Hedda Cohen.

Portal Sizing and Roadmap

Hi,
I need some suggestions in portal sizing since I am new to this field. We have a external-facing portal with an user base of around 2000. Concurrent users would be 100. Portal is integrated with ECC, BW and BOBJ (around 9 reports).
I have read about Quick Sizer tool. For 100 concurrent users, what should I use: user sizing or throughput sizing? Is it recommended to follow the results from this tool? What if the user base increases in future? Is there any other approach to work on portal sizing?
Also, what are the things I need to take into considerations for the future road-map (Scalability, maintenance, etc) ?
Thanks,

Hi Sushil,
Thanks for sharing the link. But it doesn't help much.
I tried using quick sizer tool and found the total SAPS as 2000 (DB SAPS: 500, App SAPS: 1500). Where do I find the relevant hardware for 2000 SAPS? I checked in SAP Benchmark results (Two-Tier Internet Configuration). Am I looking at the right place?
We were thinking of going for 2 core / 8 GB RAM.

Some Doubts on SAP Sizing.

Hi Experts,
I am doing sizing for SAP SRM 7.02 server for 25 users concurrent users.
I have entered the following details in the quicksizer tool. I have entered 25 in Medium activity users.
Following results are displayed.
So please tell me the inputs are correct in quicksizer or not? correct me if I am wrong.
In the result it shows 2000 SAPS (Total CPU requirement in SAPS), so please let me know what 2000 SAPS is?
In next screen it shows 500 DB SAPS, here also I am confused.
Please anyone explain me the result, I am newbie in quicksizer and need your help.
Regards,
Amit.

Hello Amit,
there is no right or wrong input in Quick Sizer. It must reflect the business of your company, You have entered 25 medium activity users. This means that these concurrently active users are working with a think time of 60 seconds. Does it make sense? In parallel you could also enter the throughput questionaire. Basically, you have to enter the number of SRM orders that are being processed in a defined period of time.
Of course it's sometimes difficult to find accurate numbers. But you have to come up with some good assumptions and ask the right people in the company (not only IT department but also someone from the application team). It's absultely crucial to work hand in hand with the right people.
Please have also a look into our sizing materials at www.service.sap.com/sizing where sizing problems are being discussed and where you find pretty good sizing materials.
SAPS is a hardware-independent unit which describes the power of the hardware: http://global.sap.com/campaigns/benchmark/measuring.epx
Once you have figured out the SAPS requirements you can have a look at www.sap.com/benchmarks --> two-tier benchmarks to find sample configurations which fits to your sizing result.
I hope this helps.
Best regards,
Sebastian

Sizing Forms Server

Does anyone have any details on sizing forms 6i Server (patch 7)
on 9iAS. I'm migrating a Forms 4.5 character mode application
to Forms 6i Web enabled and trying to size the middle tier. Any
advice / tips / gotchas would be appreciated.
Thanks

Rob, the sizing doc is a good place to start. I am currently
working on a project where I need to scale to 500 concurrent
Forms users. The general rule for f60webm process on Solaris is
12-15mb of RAM per concurrent user. Our app is running at 15mb.
(So much for Forms optimizations). That equates to 7.5Gb of Ram
across multiple nodes to accommodate the forms users. That does
not account for the other processes of O9iAS as well as the OS
level processes.
I usually start with 128Mb-512Mb minimum for O9iAS (depending on
services running, lets say its just forms runtimes using the
servlet 128Mb.) Add about 25Mb of Ram for each Jserv engine you
want running, and each Jserv engine supports 100 concurrent
forms users without running into degradation.
About 128Mb for Solaris but 256Mb minimum is better.
Where are we at: 256Mb + 128Mb + 25Mb + (15Mb x # Users) = Total
Ram needed. Add 10% to that.
Disk space needed is determined by what you need to do with it.
We simply need enough to mirror system partitions, and module
deployment directories. Your mileage may vary.
Hope it helps. -- Al

Reporting services in three tier SharePoint 2013 environment

Hi,
I am trying to integrate SQL Server 2012SP1 Reporting Services in a three tier SharePoint 2013 environment, but it seems it is not succesful.
The setup is as following:
SRV1: SQL Server with content, config,... and the Reporting Service databases.
SRV2: SharePoint 2013 Application server & Central Administration
SRV3: SharePoint Web Front with SharePoint sites
All application pools are started with domain accounts on SRV2 & 3
When opening the Central Administration site, the Reporting Services Service Application and its Proxy is created and configured. On SRV2 the Application exists in the application pool in IIS, but it does not appear in the SRV3. Should it be created manualluy?
In Central Administration, when opening the site settings the Reporting Services section is created, but when opening the Site Settings for the root site the section shows variables:
$Resources:ReportServerResources,ReportServerSiteSettingsGroupTitle;
$Resources:ReportServerResources,ScheduleList;
$Resources:ReportServerResources,SiteLevelSettings;
$Resources:ReportServerResources,ManageSiteDataAlerts;
I believe i need some help here.
Thanks in advance.
Best regards,
J

Hi J-S,
Generally, the issue occurs if you are in the Windows Powershell instead of the SharePoint Management Shell or the Reporting Services - SharePoint mode feature is not installed. So, please double check you are using the SharePoint Management Shell or install
the Add-in by installing the rssharepoint.msi instead. Here is the download link:
http://www.microsoft.com/en-us/download/details.aspx?id=35583
If it is not the issue, please install the Reporting Services - SharePoint mode from the SQL Server 2012 installation media.

Single Sign on in a 3 tier architecture between SAP Netweaver CE and R/3

Hi All,
I am trying to implement SSO using SAP logon tickets in a 3 tier architecture between NW CE and R/3. But so far I have not been able to crack this.
Let me describe the scenario in detail:
We have two Java EE applications on Netweaver CE7.2 Application Server:
1. UI: Just handles all the UI logic : js, jsp, css, html, extjs .It calls the Business Layer Java EE application to get data from back-end systems.
2. Business Layer: Calls R/3 SOAP services does some processing on them and exposes the data back to the UI via a Restful JSON service (implemented using Java Spring framework)
Both UI and Business Layer Java EE applications define login modules to be used for SAP logon tickets. So the architecture is like this:
UI-RESTfull-->Business LayerSOAP->ABAP R/3
So ideally when the UI link is clicked it prompts the user for authentication (uses CE UME) and then the UI applications calls the Business Layer which then calls R/3. This unfortunately doesn't work. The authentication between UI and Business Layer Application fails.
However if you remove the Business Layer Java EE application and call the SOAP service directly from the UI. SAP logon tickets starts working.
So I have been able to make SAP logon tickets work with the following 2 tier architecture:
UI---SOAP--->R/3
So my Question is:
Is there a way to use SAP logon tickets in a 3 tier architecture between NW CE and R/3 (For the scenario described above)? Any help/pointers/documentation links would be great

Hey Martin,
To enable SSO I updated web.xml and engine-j2ee.xml for both UI and Business Layer application according to the login module stacks defined (the first one) in the following link:
http://help.sap.com/saphelp_NW70EHP1/helpdata/en/04/120b40c6c01961e10000000a155106/content.htm
Initially both UI and Business Layer had the same entries for web.xml and engine.xml. But since this was not working I did all kinds of testing. For UI i used FORM based authentication and for Business Layer I was using "BASIC" authentication.
I tested the following Scenarios:
1. Without any changes to the above XML files: The Business layer rejects any requests from the UI . I checked the Browser and "MYSAPSSO2" cookie was created. Somehow UI doesnt use this to call Business Layer. Or the Business Layer rejects the token itself
2. I removed authentication from the Business Layer application (Web.xml) keeping the UI same: The call went to R3 but returned a "UnAuthorized" error back. In this case also at the browser level "MYSAPSSO2" token was created but was not used by the business layer to call R3.
3. The did all sorts of permutation and combination with the sample login modules provided (See link above) on both UI and Business Layer application . Nothing worked. All combinations led to two results which were the same as 1 and 2
It seems all this is happening because of another application in between UI and R3.
Hope this Clarifies.
Thanks,
Dhannajay
