Hi,
You know what ?
Step by step installation is different in every company because each company has a different usage of SAP software.
It is precisly your job as a SAP sys admin, to study the problem, to solve it and to write the step by step documentation.
In my company, it took me one month and my documentation is 250 pages long.
You will not get someone else doing YOUR job instead of you.
The standard SAP documenation is perfectly enough to study your particular case...
Good luck !

MSCS Cluster Installation

Hello Experts,
Can anybody help me configure the SAPGUI on the end user's system in a MSCS Cluster installation ?
I have Central Instance on Node 1 and Dialog Instance on Node 2 with SQL Server 2005 on Windows 2003 Enterprise Edition. The SQL and SAP cluster is working absolutely fine, but when there is a failover to Node 2, the user's connection to the server is getting disconnected
Please advice.

Mscs cluster failover

Hello,
We have installed production on MSCS cluster.Installation is finished successfully.Cluster resources for ASCS and SCS instance in sapgroup
are not getting failover.If we take SCS instance resource offline and try to failover ascs instance resource manually,it doesnot work out first time.But 2nd time it worked out.Also,with same status if we restart one node,ASCS instance resource doesnt come online.
We tried out many things without success.Plz help ASAP.
Regards,
shital

Hi,
MSCS needs a lot of steps to configure correctly.
First try out with one or two physical disk resources if they are completely failover. then try SAP resources.
I have two nodes (Active and Passive), Active acts as Database instance (mssql), and passive acts as dialog instance (R/3). When passive has problems and shuts off, then the active node takes over the passive resource (R/3) and acts as a central instance. After the passive comes back online, then you have to move the R/3 resource from the active node to the passive manually, not automatically.
Please let me know if you still have problems.
Regards.

Best plan to MSCS cluster NW700

Gurus:
We have a sandbox NW700 as a POC for MSCS cluster.
We do not care about hardware with enough funds.
We want a full MSCS clustered CI, DI , SCS , ERS and DB, therefore each part is HA.
We also plan a webdispatcher in front of the NW700 and will not be clustered.
Could you please give some high level recommendation to achieve above HA?
Thanks!

Hi,
Yes, you can install MSCS cluster. You need to be having 2 nodes. CI and DI will be local on both the nodes. ASCS and DB will be installed on virtual hostname and directory will be moving across 2 nodes. ERS will be installed on both nodes locally.
You can read the installation guide for more information.
Thanks

Java Add-In installation on a existing ABAP System (MSCS Cluster)

Hi all
we try to install a Java Add-In for a already existing ABAP System with
SAPinst. The ABAP System is a NetWeaver2004s SR1 System in a MSCS Cluster.
We have the Problem that we can´t choose the Installation Drive during
the SAPInst Define Parameter Step during the "Central Services Instance (SCS) Java Add-In" Installation.
But in the Installation Manual for
NW2004s Java AS in Chapter 4.3.2 is stated:
"Caution: You must install it on the same shared disk as the ASCS instance."
If I run the Installation, the SCS will be installed on the local disk E:
beside the Central Instance. But it need to be on the shared Disk P:
beside the ASCS installation. How can I control this?
Stefan

obviously the network share saploc is existing in your system an pointing to a local device.
Delete the local saploc share, install SCS instance, run MSCS first node, additional node, create the local share saploc again (don't forget to set permissions on the share, the default permission did only allow Read vor Everyone) and proceed with installation.
There is a note in creation for this issue.

PI 7.1 Installation on MSCS Cluster

Hi Sapers,
                     I'm In the middle of Installation of PI 7.1 on MSCS Cluster
                     My Problem is while Installing In Node A I have chosen for Host Agent and SAPOSCOL a Shared Drive(G:) which
                     Should actually be a Local Drive(C , But In Node B I have Chosen Local Drive (C
                     Now My question
                     1) Can I change the path In the Registry, If yes can anyone tell me the procedure and
                      2) What would be the implications or Consequences?
                      3) Will My Installation Go Successfully
Thanks In Advance
GHK

Installation of SAPOSCOL on a different logical partion within the same local host is fine, obviously not on a different host as the SAPOSCOL is the operating system collector for the host on which it is installed.

How to install CCMS agent in MSCS cluster system?

Hi,
We just migrated our WAS 7.0 system from a single to a MSCS cluster system and we need re-install CCMS agent on it. New cluster system have two nodes. Each node we have local SAP instances. We have central instance for message server running on a shared drive, which can failover to one of the nodes. My question is when I install CCMS agent, where I should I install it? Each node of the cluster on local drive or only shared drive or I have to install on three places?
Thanks you.
Yujun Ran

Hallo.
Did you solve your issue?
I followed Oss note 536954, but I am not sure that it is for new cluster system.
Furthermore, the CCMS agent that you installed, point to a CEN system (as Solution manager for example) and as second system to the central instance ?
Thanks.

Cluster Installation - SQL 2005 / 2003 - Creating cluster group

Hi All,
I am working on the cluster Installation in our environment and facing some issues at the time of installing first node MSCS Installation. let me summarize the activities done so far
Environment Details
Physical Disk :
G: (Physical Disk - SAN )
I : (Physical Disk - SAN )
C: Local disk
Q: (Physical Disk Quorum - SAN )
F: (Database and logs)
-- > SCS installed locally in the server in G drive
Virtual Hostname and IP : SeparateIP & cluster1
Node 1: Hostname and separate IP
Node 2 : hostname and Separate IP
Installed MSCS service and tested the same - its working fine
Installed SQL 2005 database in cluster mode and its working fine
Started installing SAP
Step 1: Installation of SCS instance in node A (Used F drive) - Successfull Installed
Step 2: Installation of First node MSCS in node A
Here I am facing an issue, in the end phase of the installation it will ask for creating cluster group -- > There I need to define the Global disk as F (Which is defined at the time of installing SCS instance) - But i dont see that disk is available in the drop down box .
Is there any other workaround to bring the Global disk while creating the cluster group (First node MSCS installation)
Looking forward for your suggestions
Thanks and Regards
Vijay

Regret for the late update
112266 solved my problem and In my case, I have bisected the disk as two but in the cluster environment that should not be the case. Ensure the the same in disk management

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.
Best regards,
Mathias

OFFLINE backup and DB13 jobs configuratins error in MSCS cluster with OFS

Hello,
We have recently installed SAP ERP 6.0 EhP4 SR1 in MSCS cluster using Oracle Fail Safe.
The installation is successful and all the failover scenarios work fine.
I need to schedule offline backups and DB13 jobs, which is not possible in current scenario as once the database shuts down it fails over to node2.
I am following sapnote 657999 to install standalone gateway on both the nodes of the cluster and assigned the service to ORACLE<SID> group. the gw<SID> is different from the ERP<SID>.
However, the service SAP<gwSID>_<gwSN> fail to come up with the following error.
The service SAPSGA_30 cannot be started on local computer
error 1067: the process terminated unexpectedly.
The ../SapCluster/sapgw and associated directories have full permission.
Following are the contents of the profiles in ../SapCluster/sapgw
default.pfl
SAPDBHOST = ORACLEPRD
gw30.pfl
SAPSYSTEMNAME = SGA
INSTANCE_NAME = GW30
SAPSYSTEM = 30
DIR_PROFILE=C:\WINDOWS\SapCluster\sapgw
DIR_EXECUTABLE=C:\WINDOWS\SapCluster\sapgw
DIR_INSTANCE=C:\WINDOWS\SapCluster\sapgw
SAPLOCALHOST = ORACLEPRD
SAPLOCALHOSTFULL = ORACLEPRD
startgw.pfl
SAPSYSTEMNAME = SGA
INSTANCE_NAME = GW30
SAPSYSTEM = 30
DIR_EXECUTABLE = C:\WINDOWS\SapCluster\sapgw
DIR_PROFILE = C:\WINDOWS\SapCluster\sapgw
DIR_INSTANCE = C:\WINDOWS\SapCluster\sapgw
_GW=gwrd.exe
Start_Program_00 = local $(DIR_EXECUTABLE)\$(_GW) pf=$(DIR_PROFILE)\gw30.pfl
Now as the service is a part of my ORACLE<ERP SID> group, everytime I try to bring the group online, it fails due to the gw service and toggles many times in the two nodes before coming to rest on one node withfailed gw service and database in the up condition.
Any insight in this regard will be really helpful.
Thanks
Nischal

Hello,
Yes we were able to configure offline backups.
We opted to install standalone gateway on both nodes and added it to the DB group. That provides the essential shell console.
You need to follow the SAP Note 657999 and then 378648 for setting the necessary environment variables.
One piece of advice, use the SID and system no. for the independent gateway, different from any of your SAP installations.
Thanks
Nischal

Failover cluster installation

Hello,
I would like to install SAP ECC6 EhP4 from System Copy (backup/restore) in Windows failover cluster environnement with two nodes.
So, I have installed MSSQL Server 2008R2 SP2 in cluster mode (using virtual host : FRSERVERSQL).
Now, I have to install SAP ECC. (A virtual host has been created : FRSERVERSAP)
I have created manually SAP SID service on "Failover cluster manager" windows menu.
Inside this service, I have created :
- IP resource
- Shared folder (sapmnt : E:\usr\sap)
- Disque resource (E:)
I have created saploc shared folder (c:\usr\sap)
Following install guide and some SCN threads, I have doubt with the way to install SAP in Windows failover cluster environnement.
I found this way on SCN :
1. Central services instance for ABAP installation.
Use the command line sapinst.exe SAPINST_USE_HOSTNAME=FRSERVERSAP
Note - during the installation time all the cluster resource should be in Node 1
2 First MSCS node installation => on Node I? Do I need to use SAPINST_USE_HOSTNAME=FRSERVERSAP ???
3 Database Instance Installation => Do I need to use SAPINST_USE_HOSTNAME? If yes, do I use FRSERVERSQL???
4 Additional or Second MSCS node installation => on Node II? with SAPINST_USE_HOSTNAME?
5 Enqueue replication server installation for ABAP in Node I
6 Enqueue replication server installation for ABAP in Node II
7 Central Instance Installation in Node I
8 Dialog Instance Installation in Node II
9 Post processing steps after system copy
One more question.
After installation is OK, If I have to refreh this environnement (with homogenous sytem copy - backup/restore),
which option should I have to use after restore? Only Database instance installation or all options described above?
Thanks for your help
Regards

Hi Durecu
I will follow the steps mentioned but my question is about options to user with sapinst.exe?
When should I have to usr SAPINST_USE_HOSTNAME?
1. Central services instance for ABAP installation.
Use the command line sapinst.exe SAPINST_USE_HOSTNAME=FRSERVERSAP
Note - during the installation time all the cluster resource should be in Node 1
During the time of Central service instance for ABAP & JAVA you have to use the Virtual hosts (that is on MSCS SAP Group DNS name, & Cluster disk before that you have to create in MSCS)
Syntax " SAPINST.EXE SAPINST_USE_HOSTNAME=<*Virtual Host Name*> "
2 First MSCS node installation => on Node I? Do I need to use SAPINST_USE_HOSTNAME=FRSERVERSAP ???
Normal SAPINST.exe Without virtual name
3 Database Instance Installation => Do I need to use SAPINST_USE_HOSTNAME? If yes, do I use FRSERVERSQL???
Normal SAPINST.exe Without virtual name
4 Additional or Second MSCS node installation => on Node II? with SAPINST_USE_HOSTNAME?
Normal SAPINST.exe Without virtual name

Configuration : We are using 2 nodes each node avialabe system attached hard disk 145 gb
DISK Space available in SAN 1200 gb
How to partition for cluster installation on the above configuration.
Thanks,
Siva

Dear Siva.
You will find a clear explanation on this in chapter 8 of the installation guide specific for your SAP release and platform (chapter "High Availability with Microsoft Cluster Service" ).
In particular, for the "SAP NetWeaver 7.0 ABAP+Java including Enhancement Package 2 on Windows: IBM DB2 for Linux, UNIX, and Windows" installation guide, you will find the response in section 8.2.2: "Distribution of SAP System Components to Disks for MSCS" ( page 164 of the guide).
Cheers!

Tns ping command is also not working when we give host name as virtual host of JAVA system
but when we change it to phyiscal IP address of the cluster server it is working fine.
Could you please let me know any setting need to be done
Sincerely
Paresh

Hi Paresh,
>> Tns ping command is also not working when we give host name as virtual host of JAVA system
but when we change it to phyiscal IP address of the cluster server it is working fine.
>> SQL error 12505 ORA-12505: TNS:listener does not currently know of SID given in connect descriptor
Virtual hostname must be resolved on both hosts while configuring SMD. Otherwise you'll not able to access Oracle Listener.
