SAP EIS Architecture and sizing

I have done lot of search for SAP documentation on sizing of different components involve in solutioning SAP EIS. But unfortunately I could not found any. Can you guys help me out here?
If you did already implemented EIS, then can you guys give me a rough estimate about your transaction volume, user base and your hardware sizing? That will at least help us for initial estimation. thanks in advance.
Regards,
Krishna

Krishna,
we hesitate to give you estimates on database and hardware sizing because, as Gabi states, sizing for EIS will vary from customer to customer based on the characteristics of the supply chain being modeled. Inputs for the sizing are the number of stocking points, number of supply paths, Bill of Material details (if applicable), the number of future periods to model, the number of historical periods of forecast and sales provided, lead times across the supply chain model and the number of models you will keep.
To make some very GENERAL comments, the more material sharing that occurs in your network the more memory needed to optimize (solve for Safety Stock) the model. Two customers can have the same number of stocking points and supply paths but if one has a distribution-only supply chain while the other has a model with a very detailed Bill of Material the distribution-only model will require much less memory to optimize.
Any further sizing information should go through Consulting as Gabi has indicated. Sizing an EIS implementation is somewhat unique and therefore general, cookie-cutter recommendations are not useful.
Hopefully that is helpful to you.

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.

ARCHITECTURE OF SAP R/3 AND APPLICATION SERVER AND DATABASE SERVER IN ABAP

ARCHITECTURE OF SAP R/3 AND APPLICATION SERVER AND DATABASE SERVER IN ABAP?
PLEASE EXPLAIN

hi
Presentation Server
It is actually a program named sapgui.exe.
It usually installed in users workstation.
The interface accepts the input from the user in the form of keystrokes, mouse-clicks, and function keys, and sends these requests to the application server.
It receives and displays the result from the application server.
Application Server
An application server is a set of executables that collectively interpret the the ABAP/4 programs.
Each application server has a profile called application server profile, that specifies its characteristics when it starts up and while it is running. It specifies:
1. Number of processes and its types.
2.Amount of memory each process may use.
3. Length of time a user is inactive before being automatically logged off.
If your ABAP/4 program requests information from the database, the application server will format the request and send it to the database server
Database Server
The database server is a set of executables that accepts database requests from the application server.
These requests are passed on to the RDBMS (Relation Database Management System).
The RDBMS sends the data back to the application server.
The RDBMS may run on database servers computer or may be installed on its own computer.
The components of application server are dispatcher, dispatcher queue, work process.
All requests that come in from presentation servers are directed first to the dispatcher.
The dispatcher writes them to the dispatcher queue.
The dispatcher pulls the requests from the queue on a first-in, first-out basis.
Each request is then allocated to the first available work process.
A work process handles one request at a time.
The work process needs two memory areas, the user context and the roll area.
The user context is a memory area that contains the information about the user.
The roll area is a memory area that contains about the program execution.
User Context
User context is a memory area that contains the characteristics of a user that is logged on the R/3 system.
1)It holds, users current settings.
2. The users authorizations.
3. The names of the programs the user is currently running.
When a user logs on, the user context is allocated for that logon. When logs off, it is freed.
Roll Area 
A roll area is a memory that is allocated by a work process for an instance of a program.
It holds the information needed by R/3 about the program execution, such as: 1. The values of the variables
2. The dynamic memory allocations
3. The current program pointer.
Each time a user starts a program, a roll area is created for that instance of the program.
If two users are using the same program at the same time, two roll areas will exist-one for each user.
The roll area is freed when the program ends.
Both roll area and the user context play an important roll in dialog processing
pls reward points dor useful ans

Best architecture and design pattern to use

I am currently designing a moderately sized LabView application and cannot decide on the best architecture/design pattern or combinations thereof to implement.
The program basically polls an instrument connected to a serial port continuously at a 2-10Hz rate. When operator clicks a button to start a run, the polled data is then filtered, has math functions performed on the data, writes collected data to files, and produces reltime graphs and calculates point-by-point statistics. At the completion of a run, some additional data files are written. I pretty much know how to accomplish all these tasks.
What is also required is main-vi front panel interaction by the operator to access a database (via a C# dll with .Net) to query for specifications to apply in order to determine pass/fail status. Setup conditions also need to be changed from time to time by the operator and applied to the data in real time (ie- a measurement offset). I have prototyped the database portion successfully thus far.
For the main vi, I started off using the Top Level Application Using Events design pattern (Event structure within a while loop). Copious use of bundled clusters and shift registers keep the database data updated. I cannot figure out how to have the top level vi concurrently poll the serial device as outlined above. The Event structure is only active when defined control values change, and use of a timeout is no help since it prevent data from being collected while the user is accessing the database. All database and setup parameters must be applied to the data as it comes in from the serial port. Error trapping/recovery is a must.
I believe what I need is two parallel processes running under my main vi (one for database and setup, the other for polling and data processing/display, but what would be the preferred choice here?
Revert back to a polled loop in lieu of Events, use notifiers, occurrences, user-defined events, Producer-consumer loops?
It�s been about 3 years since I have had an application on this level (which used a state machine architecture), and a lot has changed in LabView (using 7.1 Prof Devel). I am currently having a mental block while trying to digest a lot of features I have never used before.
Suggestions Welcome!
Thanks.
~~~~~~~~~~~~~~~~~~~~~~~~~~
"It’s the questions that drive us.”
~~~~~~~~~~~~~~~~~~~~~~~~~~

I suggest a (3) state machine(s) architecture. The first is the user interface. Your main VI is a good start. Another state machine handles the instrument I/O (your serial polling). The third handles all data processing. The three loops run independently. Each has a wait to allow LV's scheduler to share CPU time among the loops. I like queues or functional globals for inter-loop communications.
This allows a lot of flexibility. Each portion can be tested alone. Each can have different timing and priority.
Spend some time thinking about what needs to be done and plan the structure carefully before you do any coding (except for little test programs to try new ideas).
I also like Conway and Watts "A Software Engineering Approach to LabVIEW", published
by Prentice Hall.

SAP SM architecture (detailed information)

using solution manager 4.0
need help finding detailed information regarding Solution Manager architecture. the documentation out on <a href="http://help.sap.com">SAP Help</a> and <a href="http://www.sdn.sap.com">SAP portal Help</a> is too high level (often simply configuration steps rather than logical description behind key concepts).
not concerned if people tip me off on books through amazon or blogs online or whatever but need to find the following info rather quickly:
a) regardless of system type (Java/ABAP) my understanding is that the SAP system is defined through Solution Manager. a SAP system (again my translation) is logically associated with a particular lifecycle stage (development/test/production). looking for detailed definitions of SAP systems, client instances (0-998 possible per system), and the types of configuration/data associated with clients.
b) transport mechanism in relation to SAP systems and clients within a SAP system
c) calculations as to how many SAP system per machine are possible in regard to the type of application hosted

EIS timeouts and XA

In debugging my XA RAR on WLS 6.1SP2, I found that if the EIS system times
 out during an XA transaction,
 then an subsequent attempts to access that factory are denied by WLS. Is
 this saying that an possible communication
 outage on my EIS could force me to re-boot WLS to free up my factory again?
 Eric


Deb,
 I've retested this again on WLS7 and I get the same results. If I can't
 communicate with the EIS system and return the XAException.XAER_RMFAIL,
 then subsequent attempts to talk to the EIS system fail until a reboot of
 WLS. I
 don't understand the logic behind this one. Does this only happen with the
 XAER_RMFAIL? Why wouldn't the next attempt still try to connect to the EIS
 system? This is a very serious issue for us, since this is saying that if
 the mainframe
 goes down, then after it comes back up the customer would be forced to
 reboot
 WLS, not a popular idea. Any ideas on this.
 Thanks,
 Eric

SAP ECC6 memory and paging issues

Dear Experts
I have recently upgraded my 4.6C systems to an ECC 6 system (DB2 LUW 9.5 on AIX 5.3 TL9 64 Bit OS)
I have been running the LPAR with 14 GB of memory and we are around 100-200+ users using the system, I was monitoring using nmon and found that Physical Memory was around 99.8% Used   (14311.8MB and 22.6MB was free) also the paging space was around 37.2% in result causing the system at times to run slow which can have a very negative effect on the users.
After further investigation I found that after a system restart the Physical Memory would start around 50.9% and increased at a steady pace until it reached 99.8% that is when the system would start using the paging space which would steadily increase, I found that the only solution was a system restart at least once a week to reduce the memory consumption.
At first glance it looked like a database manger memory leak with the process db2sysc, so I searched the net with the search words u201Cdb2 memory leaku201D and found the following APARs and notes.
APAR JR30285 - Pervasive memory leak when compiling SQL statements that use SQL/XML functions
APAR IZ35230 - There is a pervasive unix-specific private memory leak in the security component
Note 1288341 - Memory leak in APPLHEAPSZ -> SQL0954C
Note 1352361 - Memory leak in shared memory area abrfci
Note 1147821 - DB6: Known Errors and available Fixes in DB2 9.5 LUW
After reading the notes and APARs I decided to updated DB2 to the latest fix pack (5SAP), but after the fix pack was implemented it did not solve the memory problem
I started look at different problems with SAP ECC6, db2 and AIX with paging/memory problems and I found the following notes to do with AIX memory and paging but none of them helped as all parameters and settings were set accordingly
789477 - Large extended memory on AIX (64-bit) as of Kernel 6.20
191801 - AIX 64-bit with very large amount of Extended Memory

1121904 u2013 SAP on AIX: Recommendations for Paging
1086130 u2013 DB6: DB2 Standard Parameter Settings
After even more investigation I found the following evidence suggesting AIX Virtual Memory Manager might have a problem
