Two R3 Systems on one Windows NT Server

Dear SDN Colleagues,
I'm starting an installation project (DEMO systems) of the Solman 4.0 and SAP ERP 2005 (ECC 6.0). I'm planning to install both systems on one Windows NT Server. About ABAP stack I know that it is possible, as such as describe in the SAP Note 28392 "Two R/3 Systems on one Windows NT Server", but wed like to know about JAVA Stack.
Is there any available SAP documentation about
installing several systems in one host?
Thanks in advanced and Best Regards,
Chacon

Hi,
you can install both Solman and ECC 6.0 on single NT host.
it is better to go for 64 bit windows installation. if you have 64 bit windows OS.
installation of java stack depands on your requirement.
download installation document from service.sap.com/instguides.
Guidelines: ( for example only)
1) first install SOLMAN 4.0 ABAP + JAVA stack on windows.
SID: SSM
instance number : 00
after sucessfull installation of solman perform post installation on that. and stop the SAP instance.
2) Now install ECC 6.0 ABAP instance , If you want to plan to use ESS/MSS like java based service than JAVA stack is required.
Either you can perform ABAP + JAVA stack or perform only ABAP installation and JAVA stack as separate instance.
SID: ECC
instance number : 10
if you going for JAVA stack as separate instance.
SID: J2E
instance number : 20
so as result you have total 3 System, for this more than 4GB RAM is required. ( for better perfomance)

Two R/3 Systems on one Windows NT Server

Hello SAP Guru ,
I have ECC6 on database DB2 for Development server and quality server as different client . Now i want to install quality server on same H/W . i go through sdn forum and market place but not found sufficient information for DB2 database , i go through
Note 28392 - Two R/3 Systems on one Windows NT Server also.
Please suggest some more information to keep in mind while doing this activity.
Thanks

Hi juan,
"When you run two systems in the same box you need to be aware that any mayor mantainance done in one system will have a detriment effect on the other one, specially if you're sharing the Database. During the installation you may find necesary to have some downtime in the system that is currently running as OS or DB restarts are potentially necesary."
I am agree with your post. but still my question is not answered . i am looking for information about what are the things need to modify in current system (either on OS , DB or SAP side) before start of new instance installation for Quality server.
let me explain bit more.
If current system having database name Dev now if i install new instance of SAP on same H/W with name QLT for SID as well as Database name. what are the things i need to change prior installation start so that not any conflict will happen (on OS , DB & SAP)
Or nothing is require to change i can just start installation as on fresh system.

Can I configure two webserver domain in one windows server

Can I configure two webserver domain in one windows server with default port. ( i.e 80 )
For Ex:- http://server-name/psp/DOMAIN/?cmd=login and another one
http://server-name/psp/DOMAIN2/?cmd=login.
If not please let me know the workaround to do so. B'coz i don't want to put portnumber in my second URL..

Hi,
You can even have serveral domains within the same webserver instance.
During PIA installation (of the second) choose option existing domain and then add an additional site.
Give the domain a unique name and port to your second application server and you are ready to go.
I usually do this on sandbox environments to keep the sandbox small , with several databases (Portal, HCM, FIN, CRM) and one PIA with serveral domain.
But is definitely not what you should do for production systems.
Each application should have it's one PIA instance.
Hakan
I didn't read the port number requirement.
You can only run one webserver instance on a port number for example port 80.
But you can still have one webserver PIA with serveral domain on the same port number as described above.

Two NWDI systemes in one landscape

Hi all,
I was wondering if it is possible to have two NWDI systems in one landscape (sharing same SLD) and do track forwarding between these two NWDI systems?
The reason I want to do this is that I want to move the NWDI system to another platform. To avoid a big bang situation I would like for the developers to be able to "forward" the code from one server to the other as they like (over time).
Do any of you have eny experience in this area?
Thanks.
Regards
Paw Iversen

Hi,
First of all thanks for your quick reply.
Our situation is that we have a existing NWDI system connected to one SLD. We would like to install a second NWDI system connected to the same SLD. We would then like to close down the "old" NWDI system. But in order to save the development components from old SLD we need some form of transport to the "new" NWDI system. A possible solution I thought of could be to create new tracks in the "new" NWDI and forward the existing SCs from the "old" NWDI system to the "new" NWDI system.
The reason we want to do this is because we would like to move the old NWDI system to a new platform without doing a system copy.
My question is then if its possible to make this kind of forwarding between two NWDI systems (connected to the same SLD to share component information).
Best regards

HT1660 I have two iTunes libraries on two different pc's (one windows and one Mac). Can I consolidate these on an external hard drive?

I have two iTunes libraries on two different pc's (one windows and one Mac). Can I consolidate these on an external hard drive?

I'm sorry I just saw the last post. I had two users on my hard drive, one for me and one for my daughter, but I am not sure what you mean by partioning my external????? I have heard the term before, but don't know how to do it. I am having serious crashing issues with this computer and believe I really need to do a clean install. I just want to make sure everything for both ipods is safe (is???? I think so, everything is......I hate when the English language does this to me!)

Is there a way to have two different iTunes for two different iPhones on one Windows User account?

Using Windows 7, iphone 4.
I've read as many threads on these forums and as many kb's as I could find, but I sttill can't figure it out. I have 2 iPhones. Let's call them, "wife" and "hubby". I want to have two separate iTunes, one for each of the phones. Hubby is the Windoows User. I don't want to set up a different Windows User for wife.
Hubby was the original iPhone. When I plug it in, iTunes recognized it has Hubby's iPhone. Then I unplug Hubby and close iTunes. I plug in Wife but iTunes stll comes up with Hubby under Devices and syncs Hubby's iTunes to Wife's iphone.
I've tried using the shift key when I open iTunes to set up two separate .itl files to no avail.
Is there a way to have two different iTunes for two different iPhones on one Windows User account?
Thanks!

What happens if you rename the iPhone "Wife" when it shows up as "Hubby", then choose a different set of apps/playlists to sync with? iTunes is supposed to be able to manage multiple devices, each with their own selection of content. Perhaps you "restored" "Wife" with a backup from "Hubby" when you first set things up which is now causing confusion.
To create a new library press and hold down the shift key as you click the icon to start iTunes and keep holding shift until asked to choose or create a library. You need to use the same technique to switch back.

PO No range when we ink two SRM system with One ECC system

Hello Experts,
We have a client requirement to link Two SRM Systems with One ECC system.
In this case what number range we need to maintain in both SRM systems for PO.
-The number range of ECC PO should get update whenver the PO is transferred from any of the two SRM system.
-We have Extended classic scenario.
-Also PO Doc type is going to be same.
Can we handle this by increasing the buffer of the number range in one of the SRM system?
Any idea...pls help urgently.
Best Regards,
Anil
Edited by: anil.s.verma on Oct 1, 2010 4:33 PM

Hello Anil,
Being in Extended Classic Scenario (leading PO being in SRM, R/3 PO number range is concidered as external because PO number is given by SRM), the only solution for you is to:
1- give same number range interval for PO (internal in SRM system 1 and SRM system 2, external number range in R/3), e.g. 3100000000 - 3199999999
2- in SRM system 2, fill in current number with (for example) 3159999999 and let empty (or current value) in SRM system 1
3- assign, in each system for your concerned transaction type, number range as internal in SRM and external in R/3.
In this way, you will avoid overlaping in R/3 between PO numbers coming from SRM system 1 and SRM system 2

When we connect two bw systems to one R/3 system?

Hi ,
When we connect two bw systems to one R/3 system,
could you please exlain what is the imact to SAP and BW in terms of query performance, batch performance,Develoment ,Quality system,security,BW Support.
Thanks in advance.
Regards,
kranthi

you can connect multiple BW to single R3 source system.
In the delta queue (RSA7 in source system), you have a field with the target system, so you don´t have problem if you have many target bw system, because the data selection is done by system field.
Challenge arises when you have multiple R3 feeding to single BW system and then you have to consolidate the master data say 0material fed from different source system R3 then you can consolidate data using consolidated infoobject.
The following components concatenate to the key of a consolidated InfoObject:
1)source system ID (two-character source system ID; permitted values are stored NW BI table RSSOURSYSTEM)
2)one blank character
3)backend object type (four-character backend object type; permitted values are stored BI table RSBWBEOTYP)
4)master data key value as stored in the source system
Note that the key of a consolidated InfoObject solely consists of non-integrated informations from the different source systems. Integration across source systems results from a (maybee repeatedly applied) data consolidation and cleasing process which unveils duplicate master data keys.
Hope it Helps

Evironment with two Netweaver systems and one BPC server

Hi there,
I heard it could be possible to use only one BPC microsoft server and direct one development/test netweaver system and one production NW system to exactly one BPC server?
Can I somehow define two instances on the BPC server? How about transport management?
We plan to implement BPC NW 7.0 or 7.5 if version is available in time.
Thanks in advance,
Dierk

Hello Nilanjan,
thanks for the immediate response!
I understood that you can access different BPC servers using one client. That would be achivable entering different servers withtin the connection wizard?
My question is if it would be possible to only have one physical .NET server and the dependent BPC client from where I can access two separate Netweaver servers (test/production). This would need something like a switch where the Netweaver system can be selected.
Reason is that my customer gets his servers hosted and wants to avoid to pay for two .NET servers.
To run development and production version of Netweaver on one physical system is not possible/recommended at all I heard.
Kind regards,
Dierk

Two operating systems in one computer - Running a program

Hi.
I have just installed two operating systems in my Thinkpad: windows 8 and windows 7. Is that possible to run a program, say Photoshop, MS Office, installed in windows 8 OS while I am running windows 7? I do not want to reinstall all the programs in windows 8 when using windows 7 because they are still in the same computer.
I tried to clicked on a program (from W8 Program x86). It asks for serial keys. I entered but it said that i do not have sufficient priviledge???
One more question:
I have an external hard drive. Is that possible when I install a program on that external hard drive, instead of internal hard drive, and run from that external hard drive? I mean: I install a program on external hard drive, then run that program in external HD from other computer?
I hope to have your insight solutions for this problem.
Thank you
Solved!
Go to Solution.

Basically all more advanced programs cannot be run this way. They utilize registry entries, app data, environment variables etc. hence are tied to the OS they are installed on.
Some simple applications, which don't require to be installed or have a portable version will work. This list does not include Office or Photoshop.
The answer for the external hard drive is the same. You'll need a "portable" application, which doesn't store any OS or user specific information.
You can look here http://portableapps.com/ for applications that are not tied to an OS.

Two SAP system in one host and one oracle software

Hi SAP Gurus,
We want to install Two SAP system (PR1 & PP1) in one host(Prdb05) and one database (Oracle). I dont want to do MCOD.
I am very confuse about what changes i need to make before start the install of PP1. Actually i do not required to install oracle software again. am i correct ?
also i do not required to install oracle client again.am i correct ?
Will it take software automatically ?
In SAP note 350251 they asked me to run ./runinstaller !!! but when we
are not installing software again why we need to to execute that.
Will you please guide us for the same.

Hi , This is what you have to do .
Couple of questions before i answer anything
1) Is your first SAP system installed ?
2) is this High Available system
What Oliver suggested is a valid option on Windows , but not on Unix .
In Unix you might face problems for user,groups because the user for ORACLE_HOME should ideally be ora<SID>, and if you have 2 SID and one ORACLE_HOME , which user will you give ?
So , it is better that you have 2 seperate oracle software installed , 2 seperate ORACLE_HOME , 2 seperate filesystems for oracle software .
Hope you understood , what i am trying to say .
Thanks

Two SNC system and one execution system

Hi Experts
Can there be possibilty of Two snc system to co exist with one execution system ECC?
IF yes can you folks please throw some light on the same?
This situation is arising because:
the Lime table in the existing system has really grown huge and the archiving is not helping becuase there are new records that are added to the system every day which are more than the archiving records
because of this huge data the upgrade is not possible and we are planning for a new setup, now to mitigate the risk we were tryin if two SNC system can coexist with one EEC system.
Now to add to the problem is there are certain business scenarios because of which we need to put in data in lime table every day
so reduction in data input is not possible.
As the data in LIME is only stock of the customer coming every day and if we just transaction data , even if we go away with all the data is not an issue with us as customer reports his existing stock on daily basis to us.
We have even thought of truncating all the tables available in in lime objects in SARA, we are thinking of this becuase system might act erratic when we setup new system and slow try moving few customer from existing to new system. as a pilot.
Supposing if we go ahead with it ,wht could be the issues ?
Thanks for all your help and suggestions
Regards
Manas Malhotra

Hi Manas
Two SNC systems can coexist together.
You need to define seperate Business System Groups,RFC settings,Logical System definition
Also you need to have seperate Identification for your master data, create your own definition in BADI
Example:If you are sending same material XXX to two SCM systems how to diferrentiate ???
Because BADi methods EXIT_/SAPAPO/SAPLCIF_LOC_001 & EXIT_/SAPAPO/SAPLCIF_PROD_001
differentiate when two ERP systems are connected to one SNC system by prefix and sufix, now you need to have your own code to differentiate
Also big time care should be taken in defining the distrubution models (bd64) and even in XI/PI like
Example: we have two TM systems coexisting with one ERP, so we used conditoned based mapping
Itu2019s a condition based mapping.
1) When TransportationRequestSUITERequest/TransportationRequest/ShipToLocation/InternalID = BP1 or BP2 or BP3 u2026 the receiver is I5YCLNT100
2) When TransportationRequestSUITERequest/TransportationRequest/ShipToLocation/InternalID = BP4 or BP5u2026the Receiver is I5XCLNT100.
Also care should be taken on master data/FICO settings which both systems use in common. like using Ztypes instead of using standard one like order type, message type. It should be easy when you troubleshoot back!!!
The inbound message parameters should be taken care w.r.t business needs
Good to have a matrix mapping like what business process coexit in both systems and which doesnot and then try to see what settings need to be tailored???

Connect two BW systems to one source system

Hi Experts!
I would like to know if I can set up two BW systems connect to one source system. We copied and built new BW system (BW2) from existing BW system (BW1). We need to have both system connect to one source system. When I execut Restore from BW2 - RSA1 - Source System, I'm getting a following prompt:
"Connection cannot be used. The connection BB is used in the DEV400 source system as a connection BW1400 to BW. Do you want to delete this connection in source system".
If I select "Delete" then it replace exising connection between BW1 - DEV and creates new connection BW2 - DEV. If I go back to BW1 and do restore then same thing happens as BW2 connection removed.
Is there anyway we can set up two BW systems connection to one source system with restore? Connection works fine since each one can connection with no issues. Just when I do restore, it removes other connection.
Thanks.

Two BW Systems to One OLTP Systems.

Hello experts:
We are in the process of connecting two BW systems one OLTP system. Currently the BW system is connected to one OLTP system.
I have many blogs here about this issue. But I am unable to see any answers on how to set this up. Table RSBASIDOC table(in the OLTP system) has only one entry. How can add another entry in this table to point to two BW Systems.
As alwasy points will be rewarded.

Why it is better to filter in the BW system rather than in R/3 ?
I would like to avoid any changes in BW, because of:
- reducing data traffic
- in the source system we have more data(fields), that can be used as filter in EXIT_SAPLRSAP_001
The data sources are unfortunately the same for the both BW systems, so I cannot differ between them.
What do you think about these solutions:
1. Modification in the source system - to pass logical system of BW into EXIT_SAPLRSAP_001 (the logical system is available just before EXIT_SAPLRSAP_001 is called, but unfortunately is not passed as parameter)
2. Pass some dummy selection parameter from BW just to identify BW system ...
May be any other solutions ?

Two Operating Systems on One Mac

The Avid software is really finicky (more so than fcp) about what OS you're running with it. We have the opportunity to get the avid media composer software version for real cheap (relatively), but I hesitate because it will mean that I can't upgrade my OS when I want to, without running the risk of breaking Avid or having to shell out more cash to get Avid running again.
So, is it possible to have 2 different operating systems on one mac? So, for the Avid system, I'll just have the perfect OS for that version of Avid (currently OS 10.4.9), and basically nothing else except necessary software for editing. And for the 2nd system, I'd have FCP and whatever OS works best for that? Would I need 2 physical internal hard drives for that work, and then just set my startup disk as needed, depending on which editing software I want to use?

Here's the link to Apple's free Boot Camp, if you want to download and try that out:

You'll then need a copy of MS Windows to install.
