Installing SAP system with MSCS

Hi,
Anyone can give me the steps for installing a SAP system with MS cluster?
Window server 2003, MS. SQL 2005, SAP ECC6.0
Regards
Chin

Hi,
Refer SAP Installation guide in http://service.sap.com/instguides
I will give an overview about the installation process.
Basic setup of MSCS 5.2 for SAP involves 2 systems, we will name it as node A(First MSCS node) and B(Additional MSCS node)
3 Cluster groups should be created for SAP, Database, Quorum
MSCS should be configured between node A and B, test the cluster by moving the groups between node A and B. Its very important to note that, Quorum disk group should not be taken offline. If its goes offline there are chances of cluster getting crashed.
Steps to be followed for SAP Cluster Installation
     In Cluster Admin, move the disk groups and shared disks to first MSCS node.
     On the first MSCS node, install the MS SQL Server 2005 64-Bit
             In Cluster Admin, move the disk groups and shared disks to Additional MSCS node.
     On the Additional MSCS node, install the MS SQL Server 2005 64-Bit
     In Cluster Admin, move the disk groups and shared disks to first MSCS node.
     Install the Central Services Instance for ABAP (ASCS) on first MSCS node.
     Install the Central Services Instance for Java (SCS) on first MSCS node.
     Cluster the First MSCS node
     Install the Database Instance on the First MSCS node
     Cluster the Additional MSCS node
     Install Enqueue Replication Server for ABAP and Java(Optional)
     Install the Central Instance
     Install at least one Dialog Instance
Before starting the installation, make sure that system logged on as Cluster Administrator.
Hope it helps

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.

Is it possible to install two SAP system with same SID but different instance numbers on one host?

Is it possible to install two SAP system with same system ID (SID) but different instance numbers on one host?
If yes, then how?
If no, then why?
Thanks in advance.

Sarim

Is it possible to install two SAP system with same system ID (SID) but different instance numbers on one host?
Yes, it is possible. If one is CI (PAS) and the second one is an AS (AAS). In this case there will be only one database.
If you are talking about two separate SAP systems with separate databases (Eg: A BI and an ECC) with the same SID then the problem will be with the database (Eg: Oracle)
The database will be installed under /oracle/SID/112_64 (ORACLE_HOME) unless one database is running on 10 G and in that case the ORACLE_HOME will be /oracle/SID/102_64
The next issue will be with the SAP file systems like /sapmnt/SID
The most important problem will be with the switch to the sidadm and orasid users and the conflicts there. If there is a need to stop one of the SAP systems and if you do a switch to sidadm and issue a stopsap command which system will be stopped ?
These are few of the many problems I can think of.
So if we are talking about two separate systems with their own databases I would rule out the possibility of having two systems with the same SID.

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.

Two SAP Systems in MSCS Oracle

Hi,
I would like to install two systems in MSCS Oracle with two nodes. In the first node I'll install a PI, and in the other one SAP Portal. My question is :
How many Oracle Database Engine should I install ? Or I should install one Oracle Database Engine with two oracle instance ?
Thank's in advanced
Francesc

Hi Thomas,
Would appreciate if you clarify following on Windows Server 2003 - Oracle 10g.
1 oracle-homes with 2 database
The 2 databases are not completly idependent because they share 1 oracle-home. if you want to update oracle you need to update both databases at the same time.
What are the points which needs to be taken care before using this option. During installation it prompts for Listener name and port - so should we use the same as used in first SAP instance.
2 oracle-homes with 2 database
The database are completly idependent. You can update both db's separately
Is there any pre and post installation steps before installation of second instance. In this case, listener would also be independent. And owner of SAP instance can start its own SAP instance.
Thanks
Davinder

Multiple SAP systems in MSCS Master DVD

Hello,
We are going to install a second SAP system in a MSCS cluster and following the installation guide "Installation of Multiple SAP Systems in MSCS: Oracle" I have been looking for the new installation Master CD for the Multi-SID MSCS Installation, but I haven't found it.
Do you know where can I find it? I suppose I do really need it, don't I?
If you have previous experience and/or tips and tricks, please don't doubtd to share them.
Thanks and best regards,

Trouble in a SAP system with load balancing

Hello masters:
I had a trouble with workitems that came from a SAP system with load balancing. They doesn't receive the workitem ID in the UWL.
I created another system in the portal as a "dedicated application server", and made the necessary configuration in order to replace the first one, and then my workitems worked fine.
However, I would like to know what appened with the first system created as "system with load balancing". Why this system didn´t pass the workitem ID to the application (web dynpro abap) that execute the workitems?
Thank you.

I hope there was some missing configuration in the first case which was not replicating the workitem from SAP Inbox to UWL.
Thanks
Arghadip

App.server load balancing for SAP System with 1 PS

Hi,
In SAP CPS 7.0 (Build M26.12) I have a SAP system with Central Instance + 10 App.servers, but all instances are managed by 1 ProcessServer.
After activating the "App.server load balancing" setting in SAP system definition the application servers are becoming visible in CPS with their load factors (number of BGD wp's on app.servers) and load numbers (number of active jobs on app.servers).
This is so far fine, but the additional functionality is not working as I would expect, I have issues with 2 functionalities:
1. Based on documentation after activating also the XAL connection the CPS should submit the job on app.server with best performance based on XAL monitoring data filling the TARGET_SERVER parameter.
This functionality is not working for me at all
2. A useful functionality after activating the "App.server load balancing" setting is that the ProcessServer is going to "Overloaded" status when all BGD wp's of SAP system are occupied, thus restricting submitting new jobs during overload situation. But I had an issue also with this functionality, after SAP system recovery from overload situation, the CPS still remained in Overload status (so no new jobs were submitted).
As a workaround I had increased the treshold values for loads on all app.servers for this SAP system, what was fine for several days, but after a while I believe this was a reason of unexpected performance issues in CPS, therefore I have deactivated the 'App.server load balancing" setting at all for this ProcessServer.
I would appreciate your feedbacks with this functionality.
Thanks and Regards,
Ernest Liczki

Hi Preetish,
This connect string option is to loadbalance RFC connections. These are balanced upon login, once you are connected to a particular application server (AS) you stay on that server until you reconnect.
Since CPS uses multiple RFC connections, this will result in the connections being distributed over the available AS resources which is fine as long as they are generally evenly loaded. If you have certain AS hosts that are continuosly more loaded than the rest, then you probably don't want the CPS RFC connections to end up on these servers.
The original question is about loadbalancing of batch jobs over the available AS resources, and this is done independent of the RFC connection load balancing. Even if all CPS RFC connections are pinned to the DB/CI host, you can still loadbalance jobs over the available SAP AS hosts, either by using SAPs builtin balancing, or the CPS algorithm by activating the checkbox as indicated in the first entry in this thread.
Finally, to reply to Ernest's question: I believe there are some fixes on the app load balancing in the latest release, M26.17 should be available on the SWDC now.
Regards,
Anton.

Integrating SAP System with Third Party Software

Hi,
I am working on an implementation project and need to integrate SAP system with a third party system. SInce I am a functional consultant, I am finding it tough to understand the integration issues. Can somebody explain me how to link up the two systems and what are the various tools available for this ?
Regards,
Rohit

Hi,
Inorder to integrate various systems we have various interface methodologies provided by SAP.
SAP systems use the following interface technologies:
ALE: Application Link Enabling
BAPI: Business Application Programming Interface
CPI-C: Common Program Interface Communication
EDI: Electronic Data Interchange
HTTP: HyperText Transfer Protocol
LU 6.2: Logical Unit Type 6.2
RFC: Remote Function Call
OLE: Object Linking and Embedding
SMTP: Simple Mail Transfer Protocol
SOAP: Simple Object Access Protocol
TCP/IP: Transmission Control Protocol / Internet Protocol
XML: Extensible Markup Language
In general we use ALEs and BAPIs.
The ALE uses IDOCs as the data transfer medium and need various middle ware systems inorder to receive and process these IDOCs.
BAPIs use Remote enabled functions which can be accessed from any platform also using any language ( like JAVA, VB etc).
Thanks and regards.

DBACOCKPIT Connection for SAP systems with SAP Router

Hello!
We are trying to integrate all the remote SAP systems and their databases (primarily Oracle) into DBACOCKPIT of SAP Solution Manager 7.1.
Our SAP Solution Manager is running on Windows with Oracle 11.2.0.2
The most SAP systems (Unix and Windows) can only be reached from SAP Solution Manger over the SAP Router connection.
It means no direct ping from Solution Manager server to the Server of managed system will work.
Question
Is it possible to integrate such SAP systems (with SAP Router) into DBACOCKPIT of Solution Manager?
According to sap note 1265134 only the DBCON-connection will be required.
By doing so (tcode SOLMAN_SETUP), we get TNS errors.
Do we miss some additional steps (adapting tnsnames.ora of SOLMAN with the entry of managed system), etc.?
Thank you!
regards

Systems can be reached via SM59, then what's the problem ?
In fact, this 'is' the standard procedure. This is as normal as you could have Solution manager in same 'network' with rest of the remote systems.
Answer should be yes, you can manage several remote sap systems from sap solution manager dbacockpit.

First: It's pointless to first install a full system and then try to overwrite the database with another one.
I would INSTALL the system using the database copy.
This procedure is call "homogeneous system copy" and there's a guide for that available at http://service.sap.com/instguides and also in "Note 151603 - Copying an SQL Server database".
The error message is coming because the database has not the proper users, you'd need to run the STM tool to adapt the users and the environment. Those steps are all described in detail in the guide.

DB Copy (MSSQL) between two SAP systems with different level and Components

Hi,
we have a SAP system release mysap 2004 SR1 and for "the upgrade project to SAP ECC 6.0 " we installed a new mysap 2004 in a new hardware (sap03) where we have also solution manager running. The new installed Mysap 2004 SR1 is alos running fine in the new hardware.
Now we would like to do DB copy from the old system (sap02) to the the new system sap03 and then we will do the upgrade to SAP ECC 6.0.
After I compared the two systems I have following questions:
1) there are 4 Software Components which are not in the new system (sap03). This are:
PI
FIN_BLERP
BP_INSTRASS
Is this necesary for the DB copy or we do not need this to be able to do the DB copy?
2) The Software Components Level is not the same. Should we have the same level to do the DB Copy?
Thanks in advance
Best regards
HanseAtik

Hi Juan, hi Clas,
just to be clear and to not stuck on the the way:
The systems are as follow:
1) the source system:
                     - Windows Server 2003,
                     - MSSQL Server 2005 with 32 bit.
                     - Mysap 2004 SR1
2) Target system:
                   - Windows Server 2003
                   - MSSQL Server 2005, with 64 bit.
                   - Mysap 2004 SR1 (with less Support package level and no PI, FIN_Basis, BP_BLERP and BP_INTASS coponents)
I hope this will work. could you post the link the DB Copy guide we are talking about?
By this way we will be sure that we are talking about the same DB Copy. Otherwise any mistake in this step will cost more work and time.
Thanks in advance
Best regards

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.

Hi Ed,
It seems that you must be attempting to install on a 32-bit platform. Please see Note 1052298:
