Multiple SAP systems on One database

Hello,
We are planing to install multiple SAP systems like SM, ERP on one database with multiple DB SIDs, it means each SAP system has its own Oracle instance. We know MCOD has only one DB SID (one oracle instance) for multiple SAP systems.
Is it possible to set up the landscape like this? Is it supported by SAP?
Can any body advice?
Thanks,
Kris

Technically, it is possible.
But SAP Does NOT support it. The only method to install one set of binaries (one ORACLE_HOME) that is supported by SAP is to use MCOD (all components are installed in one Database)

Multiple SAP Systems In One MSCS Cluster

We have installed a NW 7.0 EHP abap stack in a MSCS Cluster with 2 nodes.
This was installed as a standard Cluster Install.
We have now higlighted a requirement to install a 2nd (Java ) instance in this Cluster Group.
The NW 7.0 EHP1 documentation and Note 1321854 shows that multiple SAP systems in one MSCS cluster is supported.
The documentation, however, is not clear if the 2nd instance can be installed when the 1st instance was installed without the preperations for Multiple Systems.
There are no further documentation or guidelines to help.
Has anyone come across this situation or managed to install 2 SAP instances in one Cluster Group based on Windows 2003, SQL Server 2005.
Regards

I am not quite sure if I understood your problem completley. But let's see...
Usually you use on on MSCS Cluster Group per SAP instance. So you have your already existing NW 7.0 ABAP stack in a separated Cluster Group, and you create a new Cluster Group for your new Java system.
You can find more information about it in this guide here on SDN:
Link: [High Availability;
More information about High Availability Setups for SAP System can be found here on SDN:
Link: [High Availability]
If you want to use the same database for your clustered ABAP stack and your new Java stack you can do a MCOD installation.
Please see Link: [SAP Note 388866 - Multiple Components on One Database - Installation|https://service.sap.com/sap/support/notes/388866]
Hope this helps.

Multiple SAP Systems to one LiveCache

Hi All,
I know some one in the past already discussed on this topic. I want to know is it possible to use a single MaxDB/LiveCache for more than one SAP System like SCM and WFD system to a single LiveCache. If this is possible and some one already done it, can you please let me know the high level config steps?. I was thinking MaxDB should able to support the MCOD concept, but I am not sure.
Thanks

Hi Narayan,
no, using one liveCache with several SCM installations is not possible.
Although MaxDB is of course possible to support an MCOD setup, the liveCache is not. This is due to the very tight coupling of the liveCache routines and the SCM ABAP code.
Anyhow, a special setup called OneDB is supported, where liveCache and the SCM database are stored within a single MaxDB instance.
This setup simplifies Backup/Restore to a great extent.
There is also no benefit in sharing one liveCache instance within several SCM instances as you can install multiple liveCache instances on a single server.
regards,
Lars

Multiple SAP Systems with one Unique ID

Hi,
SAP recommend to have <sidadm> and <sapserviceSID> user account for each system.
Currently we create domain users for each SAP System. We are installing many test servers and trying to see if I can avoid creating domain user account for each system and use only one account to administer all test sap systems.
Just wanted to know if there is any way to have one domain SIDADM user id and one domain SAPService user account to run multiple test SAP systems?
Thanks,

Hi,
Multiple test system you have different SID. so you must use different SAPserviceSID user. But you can use one SIDADM user with the proper permission with other test systems.
I have used in OS400 environment with single SIDADM user id.
please check with users with permission sap notes or document.
But SAP not recommanded this.
Thanks and Regards,
Jibin.

Multiple SAP systems in MSCS with Oracle

Hello,
We are going to install a BI instance in a MSCS cluster in which there is already a SAP system installed and clustered.
The SO is Windows 2008 and Oracle 10.2.0.4.
My problem is about the Oracle sw. In previous SAP releases there was a guide called "Installation of Multiple SAP systems in MSCS: Oracle".
For my release Netweaver 7.0. EHP1 SR1, there is no specific guide. All the references are the installation guide and part related to MSCS installation and a white paper about "new configuration of multiple SAP systems with Windows 2008 Failover Clustering".
In all that documents I haven't found what to do with the database. In the beginning of the installation documents says that Multiple Oracle_home for different database instances are not supported in an MSCS configuration. But in the pages related to the MSCS installation says "if required, set up multiple Oracle Homes".
So, what's the option? Multiple Oracle_homes or MCOD? Be in mind that I already have a SAP system in this cluster, so I already have an Oracle home c:\oracle\<SID>\102
Have you work in this scenario?
Thanks and best regards,
Ana.

Hi,
Officially SAP does not support Multiple SAP Systems in One MCSC Cluster. If such installation & configuration has been done by SAP Global Technology Partner then and then only SAP provide support.
what's the option? Multiple Oracle_homes or MCOD?
GO for multiple oracle_home , in which the same drive letter for oracle_home should be used on local disks in both MCSC cluster nodes. And the same oracle_home should be junctioned to the shared location on shared space.
The Chapter 7 High Availability with Microsoft Cluster Service of [Inst. Guide SAP NetWeaver 7.0 incl. EHP1 SR1|http://service.sap.com/~form/sapnet?_SHORTKEY=01100035870000659894&_OBJECT=011000358700000353072009E] contains all the required information with detail. Refer it.

Assignment of One Solution ManagerDiagnostics Agent to Multiple SAP Systems

Dear Experts,
according to the Powerpoint presentation attached to SAP Note 1365123, one single Solution Manager Diagnostics Agent can be used for E2E RCA with multiple SAP systems running on its physical host.
I have installed one Diagnostics Agent on a server where three ABAP systems are running. Each ABAP system on this server has been installed under an alias (i.e. all these SAP systems are reachable under the same IP address. No virtual servers with individual IP addresses have been defined.). I want to configure each ABAP system for E2E RCA. When running the Managed Systems Setup procedure for E2E RCA, I am not able to assign the diagnostics agent to more than one of these ABAP systems - after the first system has been configured for E2E RCA, the entry for the Diagnostics Agent on this particular server is no longer available in the drop-down list of Diagnostics Agents when configuring the next system.
Is my understanding of the presentation mentioned above wrong, or am I missing a trick here? How can I assign the Diagnostics Agent to all three SAP systems that are running on the same physical host?
Details about the environment:
SAP Solution Manager: SAP EHP1 for Solution Manager 7.0 (SP Level 24)
Diagnostics agent version : 7.01.7.0.20100326100205
Thank you for your time,
Rainer Walter

Hello,
Have you followed all the rules?
Rule 1
Consider the diagnostic agent as a standard SAP system
Rule 2
Install one Diagnostic Agent per host (Physical or Virtual) (You mentioned you don't have virtual hosts)
Rule 3
Each Diagnostic Agent gets mapped to the SMSY repository using the server name key
Rule 4
Do not install a Diagnostic agent on a host that only run databases or SAP Central Services
Rule 5
An Agent can only conenct to one single Solution Manager System
If you install multiple Diagnostic Agents on the same host, each one needs to be connecting to a different Soltuion Manager system
Rule 6
Choose the adequate diagnostic agent installer/version
Rule 7
In a switch over scenario diagnostic agent must move with their respective virtual host and managed components
These are the rules attached to SAP Note 1365123. You need to comply to the rules.
If you have multiple agents ont he same host, then they need to conenct to different solution manager systems....according to the rules. One agent per physical host is one of the rules...specifically rule #2. This is my take, and it seems pretty clear here.

Paul

Connecting One process Server to Multiple SAP Systems

Hi Experts,
We have a licensed version of the SAP CPS with the Process server limit parameter set to 4, which means we are limited to 4 process server as per my understanding. But when we create a SAP system the process server and the respective Queue is automatically created. SO that means we can create a max number of 4 SAP systems with 4 process servers!!
Or is there a way we can connect one process server with multiple SAP systems ?
Thanks,
Eric.

Yes - Process server limit parameter set to 4 means your CPS environment can start jobs in 4 SAP systems only.
Maybe "SAP Business Automation Enabler (BAE) Connectors" could be useful to you in your situation.
- Check the CPS admin guide for more information on BAE connector.

David

Multiple SAP systems in MSCS

Hello,
We would like to install an ECC 6.0 and a CE in a cluster MSCS of two nodes.
I've found the SAP documentation "Installation of Multiple SAP Systems in MSCS: Oracle" but the doc version is 03/30/2007. Could you please tell me wether there is a new version of this document? or where can I find more documentation about this?
Is it recommended to create a domain between the cluster nodes? We're going to have 3 MSCS clusters with two systems in each cluster, should I create a domain for the three clusters, one domain per cluster or no domain at all?
Thanks and regards,
Ana.
Edited by: systems2111 on Feb 3, 2010 9:46 AM

Hello Shailesh,
The scenario is the following:
- MSCS between ECC and CE.
- MSCS between Solution Manager and nothing.
- MSCS between Websphere and SAP Business Objects
Every MSCS has two machines. for example, ECC will run on one machine, CE oon the other machine and in case of problems the cluster will run the ECC in the CE node.
I don't know if I have explain myself, but, anycase, please ask me with your doubts.
Regards,
Ana.

Centralised EHS system and users and organisations in multiple SAP systems

Wanted to have your experience/ advice or experience in setting up a centralised EHS system talking to multiple SAP systems and other ERP systems
If the client have sister companies and locations in multiple SAP systems , can we go for a centralised EHS system talking to multiple SAP systems
Is there a concept of application ID in EHS system : If so how EHS system can identify the < to EHS system records to tag the system > , <EHS system Records bound to have different configs for each ERP systems> and < from EHS system records to multiple SAP systems >
Can you list client experiences or roadblocks for this type of design

Hello
the answer to your question is: may be you can use a central EHS system. The reason is: EHS is correlated with MM. A SAP system in which EHS is used without MM makes "not realy" sense. So it is a matter of definition "what is a central EHS system".
EHS it selfs uses SAP standard techniques. That is "ALE" distribution to other SAP systems. The distribution of EHS data top NON SAP systems is possible to via XI (which is the common solution). If you use as the scenario SAP to SAP you must make your that standard EHS customizing is the same on both sides.
Furthermore SAP EHS is a "great" module with several submodules. So regarding each of the potential scenerios you need to check the necessary prerequisites. It ois very common to have EHS PS, DG, HSM in one system and to distribute data via ALE to a different system so that the EHS data can be used "decentral" in the several SAP logistic processes.
In most cases you need to distribute per ALE at least DG master and hazardous substance master.
As a starting point take a look here: http://help.sap.com/erp2005_ehp_05/helpdata/en/c1/eda0f591ec12408b25e7a1b369ca45/frameset.htm

Hope this helps.

Single ADS for multiple SAP systems ?

Can a single ADS installed in a JAVA stack possibly along a EP 7.0 serve multiple SAP systems in my landscape. We got ECC 6.0, EP 7.0, BI 7.0, SRM 5 etc in our landscape. I was wondering whether I can install ADS on any of these systems with Java stack and leverage the functionality to other SAP system or should I have ADS on all the Systems ?
Help appreciated
Thanks

We are using one ADS for more than 10 systems in our product development. It works fine.

Fall back systemwhen multiple SAP systems trying to acheive SSO with BOEXI

Friends,
I need a small clarification on ' SSO between BOE XI 3.1 and SAP BI 7' Scenario,
Say when multiple users log on through their SAP EP Portals or Netwever Portals, they use their tokens generated by their respective EP portals which are passed through the 'Web application server' hosting BOE environment.
1) When its a Single EP portal , we can have have a fall back system. when we register its logical name in the CMC of BOE Environment , a typical SNC.But what's the fall back system for multiple SAP systems?
2) Also Whether there are any pit falls via token method when more than one SAP system communicating to BOE?
3) Do we have any documentation for this?
Thanks ,
Sivakanth.

Hi Sivakanth,
the normal scenario for SSO is the following:
When you said ''back end system ', i did not get it.
Enterprise Portal -
(iView)-------> BOE -
> SAP BI <- This is your backend system
Well Could I define more than one logical name there in SNC tab of CMC.?
I assume you have the following situation:
(EP1, EP2, EP3) -
> BOE -
> (SAP BI 1, SAP BI 2, SAP BI n)
You can define more than one entitlement systems in the BOE CMC and also configure for each one of them for SNC. Please note that we are talking about server trust and NOT client trust here. It is all about letting your sap system and the boe system trust each other. If you have your portal with client SNC configured (ie. the user logs using a certificate and an SAP logon ticket is created) it is NOT necessary to configure SNC in the CMC (Please refer to the section "Configuring SAP Server-Side Trust" in the installation guide for the integration kit for SAP) side.
Back to the SSO scenario now: When a user connects from an enterprise portal on the BOE system the logon ticket, generated from the portal, is forwarded to the back-end system, which is defined in the portal iView the user is currently navigating through. If it is a Crystal Enterprise iView then you just have to select the appropriate system alias of your back-end system in the System drop down menu when creating the iView. For URL iViews you must utilize the relevant openDocument parameters. If you do not define anything at all when creating the iView then BOE tries to authenticate the logon ticket against the SAP BI system you selected to be the default one in the "Authentication->SAP->Options" tab of the CMC.
If what you want is just to distribute the load between your SAP back-end systems then you should consider utilizing an SAP cluster for your pursposes. As explained before BOE will not distribute the requests evenly on the back-end systems. It will try to contact either the system defined in the request (iView) or the default system. To be honest I am not sure what happens if the explicitely defined system is not available but I think that an error message is what you should expect then. I do not think that in this case the BOE system tries to use the system defined as default.
Another part is what kind of security is defined in BEX querys..as i read from SAP IK guide, we can import all the roles which are defined at ABAB level.
Will there be any security threats to SAP data via this method.
It is true that you can import all roles in your BOE system. But keep the following four things in mind:
1) You can restrict on the BOE side the users which are authorized to logon in the CMC and import the roles (normally only the BOE administrator is authorized to do this)
2) Importing a role means that an SAP user can try to logon the BOE. Still the logon process can only be succesfull only if the SAP user has special authorization on the SAP side (Please check the Appendix "Authorizations" in the installation guide of the integration Kit for SAP.
3) You can restrict the access to data by assigning authorizations only for specific infoareas/infoproviders. In order to partially restrict data access in a given infoprovider (e.g infocube or multiprovider) you can utilize authorization variables in your BW query.
4) You can further restrict access on specific reports either on the BOE side or on the portal side (by rstricting access to the defined iViews).
For sure you must invest some time to define and implement your security concept.
More over could you please answer other 2 questions in my original question.
2) Also Whether there are any pit falls via token method when more than one SAP system communicating to BOE?
3) Do we have any documentation for this?
2) As long as your portals, the back-end systems and your BOE system are configured correctly for SSO this should not be a problem. Well just a tip based on my experience: be sure to use full qualified domain names for your systems in the iView definitions. And do not forget SSO works only if all systems are in the same domain.
3) As said in my previous posting the netweaver documentation regadring SSO setup maybe interesting for you. As far as I know the multiple systems scenario is not contained explicitely in any official BOBJ documentation. I assume that you already went through the installation guide for the integration kit for SAP.
Please tell me if you have a completely different scenario in mind

Stratos

Connecting to Multiple ECC systems via one Gateway system(Dynamic System Selection)

Hi Experts,
We have multiple ECC systems and one Gateway server. We want to connect to these different ECC systems using one GW system.
I have created System Aliases for these ECC system in GW system. For a service, i added 2 system aliases.
Now we are looking for the solution where UI can provide the system alias (it wants to connect) as a parameter while calling oData Service.
Please help.
Regards,
Rohit

Hi Rohit,
we have a similar scenario where we have two system aliases for one service. Both aliases point to the same system, but different clients; it should not make a difference though, having different systems. The feature you are looking for is Multiple Origin Composition (MOC).
There are a couple of things you have to consider:
in the SEGW the entity to be called has to be marked as addressable
the URI of the service needs to include the tag for MOC (;mo) --> http://sapgw.domain.org:8000/sap/opu/odata/sap/ZSOME_SERVICE;mo/entityset
Without the ;mo the call will be routed to your default alias. The ;mo will route the call to both systems. Using MOC will generate an additional key property into your entities --> SAP__ORIGIN. The property is the alias. If you want to route to a specific system you have to provide the SAP__ORIGIN like providing normal key properties in your requests.
This will look like this:
<content type="application/xml">
<m:properties xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices">
    <d:SAP__Origin>SOME_ALIAS</d:SAP__Origin>
    <d:Identifier>SOME_IDENTIFIER</d:Identifier>
    <d:Doublet />
</m:properties>
</content>
The original Entity only consists of the key property "Identifier" and the property "Doublet". "SAP__ORIGN" is added via the ;mo.
Hope it helped...

Query about multiple connection pools under one database

Hi,
I have s query about connection pool, now we have a requirement,
we have two schemas in one db, some data store in one schema, some in another schema,
all tables are the same, but data is different, we want to retrive all data under two schemas,
so we need two connection pools under one database,
I have set two system DSN, and each connection pool was mapping to one DSN,
but after I importing tables into RPD, when I view data, there is a dialog let me select connection pool. so If this, when we drag columns in answer, it will definitely get wrong.
so how to realize this function about multiple connection pools under one database and we can get data normally.

Hi,
Try this step
1)Better to create two different DSN for the same database with different user id and password
2)now create multiple connection pool in the same database in u r RPD physical layer .

Can we assign multiple SAP alias to one Enterprise user?

Hi,
Customer has a request to assign multiple SAP roles (imported to BOE) to an Enterprise user. The purpose to do this is to be able to refresh different reports reporting off different SAP system by one single user.
Can the above been done by any kind of configuration or it's not possible at all?
thanks and regards

Yes, he wish to assign several SAP users from different SAP system to one Enterprise user.
Actually customer wants to assign multiple SAP alias (from different SAP system) to one Enterprise user. (In this case, does it mean he needs to enable SAP authentication for multiple SAP system?) And then he can use the Enterprise user to refresh any reports, e.g report from BOE, and reports from different SAP system.
Can the above be done through any configuration?
thanks and regards
