SAP 4.7 / MSSQL Cluster Installation

Hi:
I am in the planning stages of a SAP 4.7 / MSSQL Cluster Installation. I have sone this same install in non-clustered MSQL 2005/ SAP 4.7 envirionments, but cannot find a lot of good documentation/advice for the clustered install.
For example, when we install nonclustered MSSQL 2005, we use a VB script that takes care of the DB configuration for us. Is something similiar available for a clustered install. Any advice appreciated.

David,
Do you have access to the install guides? The install on the cluster is covered extensively in these.
Hope that helps.

SAP Cluster Installation instance number issue

Hi,
We had some problem about the sap cluster installation .
OS : AIX 6.1
Database : DB2
We are trying to install the sap cluster under AIX + DB2.
But we are not sure whether we have
CI instance = 00
DI instance = 03
will it have problem . ( e.g. will we need to adjust the transport
configuration eachange due to the instance number different )
Because we had saw other case on window which is
CI instance = 00
DI instance = 00
So which is working fine and no problem.
Please help and give some recommendations. We would like to confirm is window / aix the same , are there any concern here( CI instance is need to different
with DI or not , if not what will be affect. ) .
Regards

Hi,
Per my understanding the
stms > system overview > [SID of the cluster] > Display TMS Configuration : System xxx > communicate tag > RFC Address
on that column is not able to use logon group.
But if you not setting that part correctly , then the auto transport is not able to do e.g. QAS forward the request to PRD
Am I correct ?
thx,
Tony

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

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

ABAP+JAVA in Cluster installation

Hello gurus,
I've read all tha SAP HA documents and have noticed that in several cluster installation they split up
the ABAP SCS and JAVA SCS from the CI when installaing a double-stack system (ABAP+JAVA).
As much as I know, the SCS instances doesn't require a lot of memory or cpu, they are not the problem when there is a bottleneck (correct me if I'm worng ...).
So, what is the reason for splitting up the SCS isntances from the cluster group of central instance ?
Please advice,
Dimitry Haritonov

Hello Dimitry,
Basically the SCS instances determine the CI. Without having running message and enqueue servers, there is not a running NetWeaver cluster at all. So these processes together with the database and the global file system are critical for the cluster and its high availability. These are the so called single points of failures and need to be protected by the failover cluster. For more details refer to sections 2.2.4, 2.3.2 and 4.1 of "SAP WAS in Switchover Environments" technology handbook available at service marketplace.
You are right that SCS processes do not consume a lot of memory and cpu. They do not require a lot of time to start so for performance reasons it makes sense to split them from the ABAP and Java processes, which are much slower. If the SCS instances are installed in a separate cluster group than the whole CI, the switchover process will take less time.
I hope I answered to your question.
Best Regards
Vyara

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...

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.

Can anyone please share some usefull documents to understand... This is new to me and doing it for first time.
Pls help
RGC

Hi,
I'm looking for a customized document for ECC installation (how to document) and not a SAP Standard one as i'm new to cluster. Please share if any.
How to configure the nodes in three tier architecture?
In which node the DB should be installed?
In which node the CI should be installed?
How to configure Central Point of Failure (CPOF)?
How the ECC 6.0 cluster works and how to distribute the resources (SAP) across nodes?
What are the resources that needed for failover from one node to another?
Expecting help.

Cluster Installation SQL

HI SME
I have installed the SQL 2005 failover cluster and SAP cluster installation both are working fine.
But whenever i am moving the SQL group from node 1 to node 2 and vice versa the Databse in the studio show recovery mode.
and application is not able to connect unless the the recovery is completed.
Note : ALL the groups in the cluster are moving perfectly without any issue . Only that DB
Database : share Drive (SAN)
Regards
Haroon

Dear Haroon.
This could be due to an issue with the cluster and its resources to come online, however I am more prone to think that this is a purely SQL Server issue. So, in order to discern it, I recommend you to perform a very simple test:
Take your SQL Server offline and bring it back online in the same node; how long does it take to recover the database? It should take the same amount of time as a failover; if it takes less time to recover on the same node, then you probably have a cluster issue.
Otherwise, I think that this is just the normal behaviour of SQL Server, but there is something that you should learn about the transaction log in order to really take advantage of its strong points, and do not suffer the possible drawbacks:
Writes to the SQL database (i.e. inserts, updates and deletes) are written first to the transaction log. Once a transaction (whether it is an explicit transaction starting with a BEGIN TRAN or an implicit transaction of a single statement) is written in the log, the user is told that the write was complete, even though it is not yet in the database. The lazy writer and checkpoint processes "follow along behind" and flush those writes (stored as "dirty pages" in memory) to the database.
A log backup writes everything (since the last log backup) to a backup file. It does not affect in any way the writing of transactions to the database.
The key here is that a transaction must be marked as "complete" in some way. This can either be an explicit COMMIT or ROLLBACK statement or something implicit like a GO statement or your connection's IMPLICIT_TRANSACTIONS setting.
If a transaction is not completed in some way and/or has not been written to the database when the service/database is stopped, the SQL Server has to recover the database when the service restarts. This entails reading through the log file, rolling back transactions that have not been committed ("unwriting" them from the database) or rolling forward transactions that have been committed in the log but had not been written into the database.
Far and away the most common reason for long recovery times is uncommitted transactions that have to be rolled back.
A good clue that this is the cause is the usage of the log file after a log backup is taken. If there is still a lot of used space in the log file after taking a log backup it means there is at least one open transaction that started a fair while ago. Common causes for this are: having your users' IMPLICIT_TRANSACTIONS set ON instead of the default OFF (especially if they leave their connections open), applications that allow transactions to be held open (again, especially when a user walks away from their machine in the middle of a session), large data loads, index rebuilds, etc. The first two scenarios need to be investigated and addressed if possible.
And now, let me ask you: How often do you backup your transaction logs? Maybe not very often, and so you have a lot of transactions that need to be rolled back/forward during the recovery of your database. To be more precise, if you are not backing up the transaction log on a regular basis, SQL Server will need to process all VLF's in the transaction log. So, it is generally recommended to setup a job that backs up the transaction log at least every hour (possibly every 15 minutes). With that done, your recovery time should be much faster. Otherwise, monitor the size of the transaction log backups and check if there are any open transactions as explained in SAP note 421644.
Cheers!!

Is MSSQL Cluster supported running on SOFS?

Hi
We plan to setup a SOFS (JBOD with FileCluster) + Hyper-V Cluster (With VMM). We then plan to create 2 x VM´s running MSSQL in MSSQL Cluster. My question is: Is it supported to place the "data/cluster disk", containing the database data-files,
on the SOFS?
Does anyone have an reference to best practice? Any blog/documentation around how to do this?

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,

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).

Hi João Cesar,
I´m faccing with the same error... I installed the solution manager Ehp1 and it have SPS20 applied which correspond to ST 400 level 20 (SAPKITL430).
When I am in transaction SMSY in section Systems and I press the button "READ SYSTEM NUMBER" is shown an error message that says "SAP customer number unknown for installation" the details of help says:
Diagnosis
Installation number &V1& that is assigned to some system(s) in transaction SMSY is not assigned to an SAP customer number in table AIINSTALLATIONS.
Procedure
Please check the log of background job REFRESH_ADMIN_DATA_FROM_SUPPORT for errors.
So, when I entry in that job log I found this error:
No customer numbers maintained in view V_AISAPCUSTNOS   | AI_SC_EN   | 106
Then I went in table/view V_AISAPCUSTNOS and inside does not contain any data!!!
All the notes I found were related to lower versions and so I could not implemented the snotes corrections!! Any notes for my release that are related with this problem?
Joao Cesar what you did for solve this problem??? You didn´t mentioned!! You only mentioned that you implemented some notes.. but which ones?!!?
