2 CIs in a MSCS Cluster

Dear Portal Gurus,
Can we install 2 CIs in each node of a 2 node MSCS Cluster ?
(we have 2 noeds i.e. 2 hosts)
Thanks.
Jack.

Hi Jack,
No I guess. You have two options.
Install Java Central instance on 1 Node and Dialog Instance on the other one. Have SCS instance + Database on both for failover. Install other Dialog instances outside MSCS Cluster
Install 1 SCS Instance + Database on MSCS Cluster and install Java Central instance outside cluster.
Regards,
Piyush
ps: please mark for useful answers.

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,

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.

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 !

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

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

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.

Oracle DB upgrade from 10.2.0.2 to 10.2.4.0 under MSCS cluster

Hi,
How to upgrade the database from 10.2.0.2 to 10.2.4.0 under MSCS cluster environment.
We are in the process of upgrading the Oracle from 10.2.0.2 to
10.2.0.4.
( 10g Relese 2 (10.2.0.4) patchset 3 for Microsoft Windows X64 -
p6810189_10204_MSWIN-x86-64 )
As per the readme.txt, we have stoped all the oracle services. We could
not stop listner - OracleP01102TNSListenerFSLoracleP01. We got the
error listner ( OracleP01102TNSListenerFSLoracleP01) need to be
shutdown. We tried to stop it, but, automatically it was restarting.
We disable it and continued the upgradation. All the oracle resources
moved to Node-2 and we got the second error ( (oracle_home)/database )
device is not ready.
Early reply is highly appreciated..
Thanks!
Nikhil

Hi ,
Shutdown Database (use sqlplus) and then try to stop all oracle services.
Check with your OS team for - All the oracle resources
moved to Node-2 and we got the second error ( (oracle_home)/database )
device is not ready.
Normally it should not be happened .
If node 1 is down , on that time node 1 all the oracle resoures moved to Node -2 .
Pls contact OS team.

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

Hi Paresh,

Virtual hostname must be resolved on both hosts while configuring SMD. Otherwise you'll not able to access Oracle Listener.

Conectivity between existent SAP Systems and migrated system to MSCS Cluste

Hi
I have an existing SAP NW PI 7.0 (Abap + Java on Windows 2003 - SQLServer 2005) and plan to migrate to a cluster with new hardware (MSCS).
I have to prepare for the installation by creating a homogeneous copy of the database but I'm a little bit confused.
-Can I use backup/restore method or only can use import/export with R3load tools? The target system is windows and sql server same versions.
-If I can use backup/restore... what is the rigth sequence to the installation? Can I use sapinst with mixed high availability options and System copy options?
-I need to use in the target system the same hostname and IP address of the actual system, so in the Follow-Up Activities we do not change the configuration between the actual system (SAP NW PI) and other existent systems in the landscape... but I do not know what is the location in the cluster to this hostname and IP:
*The central instance will be in the local disks in the node 1. Is the node 1 the rigth option to use the hostname and IP of the actual system?
*The SAP Cluster group has a virtual hostname and IP, it has message and enqueu services. Is the sap cluster group he rigth option to use the hostname and IP of the actual system?
How is the communication between the other systemas and the new clustered system?
Thanks for your help

Can I use backup/restore method or only can use import/export with R3load tools? The target system is windows and sql server same versions.
You should follow the SAP guidlines in performing a homogeneous system copy.
I need to use in the target system the same hostname and IP address of the actual system, so in the Follow-Up Activities we do not change the configuration between the actual system (SAP NW PI) and other existent systems in the landscape... but I do not know what is the location in the cluster to this hostname and IP
This is not possible. If you follow the SAP instructions for installing NW 7.0 in MSCS you will create two cluster groups: DBGroup and SAPGroup. You will therefore have two virtual IP addresses, one for SAP cluster group and one for DB cluster group. If you retain the current IP address/hostname for the virtual SAPGroup, you will need to follow the SAP guidelines for performing a SAP system copy to find where to change the database hostname/IP addresses to point to your new DBGroup.
The central instance will be in the local disks in the node 1. Is the node 1 the rigth option to use the hostname and IP of the actual system?
If you are meaning the ASCS then this should be installed on the disks that are part of the SAPGroup in the cluster.
If you mean the dialog instance (or the Central Instance of a Java stack) then this can be on a local disk for node 1, and not in the cluster.
The SAP Cluster group has a virtual hostname and IP, it has message and enqueu services. Is the sap cluster group he rigth option to use the hostname and IP of the actual system
Yes, this will be the message server host for ASCS.
