DB & CI - MSCS Active-Active Cluster configuration.

Hi all,
I could find several solutions searching for posts about Clustering, but am still having doubts.
We are going to install servers for our erp application - SAP. One server shall be DB server (Database) and another CI server (Content). OS - Windows Server 2003 -R2, Enterprise Edition and SQL 2005.
We want to have both these servers to be clustered as Active-Active. Going through the posts, Active-Active does not seem to be recommended from microsoft compared to Active-Passive cluster.
Can someone please guide about this ?
Also if someone can please provide link - how to configure Active-Active cluster in Windows server 2003 for SAP servers. Sort of step-by-step guide if available ?
Thanks in advance.

Hi,
You don't tell us which SAP ERP product you want to be clustered...
ECC is different from R/3 for this matter...
SAP MSCS Clusters are active-active in the way that each node has its own role in nominal configuration (no fail over).
SAP MSCS clusters are Active-PAssive in the way that tha database or SAP components run on only one single node.
For ECC6, you have SQL server running on one node and the SCS running on the other node.
If you want to really use the cpus of the second node, you can install the CI (which is in fact the first DI) on the second node.
For MSCS, you have to follow the configuration explained in the SAP installation guide. Otherwise your system will not be supported.

Olivier

  • Oralce Failsafe Active/Active Configuration

    Hello,
    I have a question about Failsafe.
    There is Active/Active configuration in Failsafe
    (in section 3.1.2 http://otn.oracle.com/docs/tech/windows/failsafe/doc_library/331/concepts/makefs.htm#sthref359)
    An example configuration is like this: 'In Figure 3-3, an Oracle database server is used for marketing on Node 1, and an Oracle database server is used for sales on Node 2. The cluster disks owned by Node 1 store the marketing files, and the cluster disks owned by Node 2 store the sales files. '
    In this configuration , are there TWO independent database existing in cluster disks? so still single instance for each database?
    And how to schedule the two nodes to activly access their own database during normal operation since MSCS allow cluster disk owned and accessed by only one node at a time.
    Could anyone explain it ? Thanks a lot in advance.

    You should be able to access Shared Services if foundation has started up even if there is an issue with RAF, if it is 11.1.2.3 then you have to log into workspace to be able to access Shared Services.
    The directory configuration is held in the Shared Services registry, it can be exported/imported using the epmsys_registry utility.
    Cheers

  • Unable to failover the services in active-active cluster node

    Hi,
    i am applying the sp2 patch for sql server 2008 r2 in active-active cluster, we have 3 services in the cluster , node 1 as 2 prefered owner and node 2 as 1 prefered owner, when i try to move the service from node 2 to node1 , i am getting the below errors
    DCOM was unable to communicate with the computer XXXXXXXXX using any of the configured protocols.
    The Kerberos client received a KRB_AP_ERR_MODIFIED error from the server XXXXXXXXX. The target name used was RPCSS/XXXXXX. This indicates that the target server failed to decrypt the ticket provided by the client. This can occur when the target server principal
    name (SPN) is registered on an account other than the account the target service is using. Please ensure that the target SPN is registered on, and only registered on, the account used by the server. This error can also happen when the target service is using
    a different password for the target service account than what the Kerberos Key Distribution Center (KDC) has for the target service account. Please ensure that the service on the server and the KDC are both updated to use the current password. If the server
    name is not fully qualified, and the target domain (XXXXXX) is different from the client domain (XXXXXXX), check if there are identically named server accounts in these two domains, or use the fully-qualified name to identify the server.

  • FTP Adapter duplicate processing of files in Active-Active cluster env

    Hi All,
    We have single active-active cluster environment and we have configured all the HA configurations for Inbound and Outbound operations (except outboundDatasourceLocal). But we faced a situation that the FTP Adapter processed a file twice. This happened when there was a fail-over in oracle database in where SOA-INFRA schema is created.
    Please let me know if anyone faced similar issue and what would be the resolution for this duplication issue.
    Thanks in Advance.

    Hi Vernetto,
    Thanks for your reply.
    I too had opened a ticket with oracle and they are looking into the issue.
    can you please let me know what are the inbound and outbound operation configurations you have specified in the 'outbound connection pools'. Also is there any other specific property you set in jca file?
    one more thing is, we have configured outboundLockTypeForWrite to 'oracle' as we are using the oracle database. but i couldnt see any data in FILEADAPTER_IN or in FILEADAPTER_MUTEX tables. you said you could see data in FILEADAPTER_IN table. so is there any specific property requires to be set which i am missing?
    please suggest.
    Thanks.

  • Active - Passive Cluster

    Hey, I have to manage an active passive cluster on SLES10 SP4. Oracle 10.2.0.4
    All oracle binaries are on a DRBD Device on mountpoint /oradata.
    This mountpoint includes the binaries and all datafiles.
    I havent installed these systems. At one stage on node died and got reinstalled by a systemadministrator.
    After a switch from the running node to the standby node, the cluster is not starting.
    Jan 3 14:36:01 a logger: Cluster Ready Services waiting on dependencies. Diagnostics in /tmp/crsctl.6114.
    Jan 3 14:36:14 a logger: Waiting for Oracle CSS service to be available before starting
    Jan 3 14:36:14 a logger: ASM instance +ASM. Wait 2.
    After issung $ORACLE_HOME/bin/localconfig add the cluster is starting, the asm instance is coming up, and also the database instance is starting.
    Shortly after that the db instance dies. Alertlog is showing something like recursive sql error.
    Looks like writing to the datafiles is not working.
    In asmcmd the diskgroups are showing DISMOUNTED (show MOUNTED before)
    so what to do ?
    a) Why is it necessary to issue "localconfig add" to make the cluster starting ?
    b) What could be a reason for not being able to write to the database ?
    c) How would you guys install an active/passive cluster ?
    c1) Install OS on both nodes
    c2) Install oracle binaries
    c2.1) on both nodes in the local files system and do the mapping to the drbd afterwards?
    c2.2) only on one node and just switch the mountpoint ?
    Chris

    Hi,
    first of all please clarify, if you have Oracle clusterware installed, or just the local configuration for local ASM.
    There is a big difference between the 2, and also using DRBD has nothing to do with Oracle clusterware (and is not supported by Oracle).
    a.) Localconfig may be necessary for a local ASM installation in 10.2. Main reason is, that the CSS service configuraton includes the hostname (which changed if you switched nodes). Hence may not be able to start ASM. With localconfig you are fixing this issue.
    Very important: It is not a good idea to run this is a cluster configuration, since it will break things (a lot of things).
    b.) If the ASM diskgroup got dismouned, then the database cannot write. Hence your problem. Why the diskgroup dismounted, you should find in the ASM alert.log
    c.) I would go for RAC One Node. Which has this all preconfigured. So it makes life easier. Search for "RAC One Node" on OTN for more information. At least I would take a manual cluster, and do mirroring by ASM, and not DRBD....
    c1.) Yes install Oracle cluster (or Grid infrastucture in 11.2) on both nodes. Like a RAC.
    c2) Install database software on both nodes locally.
    c2.1) No. No DRDB.
    c2.2) Both nodes. Same installation.

  • Is it possible to configure NLB clustering in Active/Active mode.

    Hello Guys,
    Just wanted to know If I can manually configure my NLB cluster to work in ACTIVE/ACTIVE mode as we can do for Microsoft fail over clustering.
    Thanks & Regards
    Amit Pal Singh

    Hi Amit Pal Singh,
    I think you must some misunderstand about the failover and NLB, I assume you are trying to install the Failover cluster, you can refer the following article to install the

  • Veritas Active/Passive cluster knowledge

    Hi All,

    Veritas active/passive cluster is very easy to use. I am not sure about linux but I guess even for linux there are having gui interface which is very user friendly. Its like cluster will use common storage and one node will be configured as active other as passive in case any failure occurs at node1 automaticly node2 will become active.

  • MSSQL2012 active/passive cluster convert to active/active cluster

    Good day.
    We have 2-node active/passive MSSQL2012 cluster (on Win 2008 R2). One "default" instance.
    We want convert  to active-active, (multi-instance).
    As I understand, one SQL instance (existing) will run on 1 cluster node and the second (new) instance on the 2 cluster node. 
    I have some questions:
    - we have cluster virtual name and ip address for existing MSSQL instance, for the second MSSQL instance we need to create another name and ip ?
    - for second MSSQL instance we can create 2 separate cluster disks (for DB and LOGS) ?
    - for second MSSQL instance we can create another DTC instance and bind it to the second MSSQL instance ?
    - we can use existing physical LAN connectors on our servers (data and heartbeat) or we need to add new LAN adaptors ?
    - quorum disk is the same for all instances ?
    Sorry for my bad English.

    I have some questions:
    - we have cluster virtual name and ip address for existing MSSQL instance, for the second MSSQL instance we need to create another name and ip ?
    Yes that would be required.
    - for second MSSQL instance we can create 2 separate cluster disks (for DB and LOGS) ?
    Yes it will be in different resource group and you can have different disk for them.
    - for second MSSQL instance we can create another DTC instance and bind it to the second MSSQL instance ?
    Same MSDTC can be used for multiple instance.

    - we can use existing physical LAN connectors on our servers (data and heartbeat) or we need to add new LAN adaptors ?
    Best to ask network team
    - quorum disk is the same for all instances ?
    Quorum is for windows cluster not for SQL server  so Yes its same for all instances

  • LiveCache on Cluster Active/Active

    Hi SAP gurus...
    is it possible to install liveCache on an Active/Active Cluster (MSCS)?
    is there any SAP note or Microsoft document available with instructions?
    thanks
    Antonio

    Hi António,
    it depends on how you define the ACTIVE/ACTIVE cluster.
    If you want to have the SCM system on one node and the liveCache on the other - this should work, yes.
    If you mean something like Oracle RAC where the liveCache is running on both nodes in parallel - no, there's no way to do that.
    For installation instructions, simply check the notes that you get by searching for "livecache + mscs":

  • RAC Active/Active VS Active/Passive 11g Configuration

    Thanks in advance.
    I appreciate your experience with implementing RAC in an Active/Active VS Active/Passive Configuration of 11g RAC.
    Much of my experience has been with Active/Active to take full advantage of performance capability of both nodes (2 node cluster). As such, I don't see the advantages of Active/Passive RAC configuration.

    The benefit is that you can save on licensing costs while gaining availability

  • SAP cluster active/active Windows and cluster active/pasive Database

    Dear Experts,
    I need to know if SAP is restricted to work in an active / active  cluster Windows R2 and database cluster with passive / active. Maybe Oracle database.
    Maybe they can give me some information on how to do it or tell me if this combination is NOT possible. Maybe Oracle as database.
    Please any information you can give me I thank.

    Hi Kumar,
    Please gothru the Installation guides under http://service.sap/com/instguides for required SAP DVD's and PAM for compatible DB's.
    In Node A --> You start with ASCS + SCS installation as below
    1.) Central Services Instance for ABAP (ASCS) -- Consists of Msg. service & Enqueue Service (Shared Disk)
    2.) Central Services Instance (SCS) -- Consists of Msg. service & Enqueue Service (Should be installed after installation of 1.) (Same Shared Disk)
    3.) First Microsoft Cluster Service (MSCS) -- This step creates the SAP cluster group on the first MSCS node and adds the ASCS and SCS instance(s) to the SAP cluster group
    4.) Database Instance
    Node B
    5.) Additional Microsoft Cluster Service (MSCS)
    6.) Enqueue Replication Server BOTH NODES, First in NODE A followed by NODE B
    7.) Central Instance NODE A-- If you install the central instance on one of the NODE A, make sure that you use a local drive, not a shared drive.
    8.) Dialog Instance NODE B-- Same procedure as in NODE A.
    When NODE A fails, the ASCS and SCS failsover to NODE B and Dialog instance on NODE B act as CI.
    Refer to below doc for more information  - http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/00004f25-6190-2b10-2c8b-fa419234c28b

  • SQL Server 2008 Active/Active Cluster in sap

    Dear Experts,
    We are planning to install Active/Active Cluster in SQL server 2008 for SAP. Our landscape is with two servers. We needed the answers for the queries?
    1. How we have to configure SAN storage hard disks?
    2. How man disks needed for Active/Active cluster?
    3. Is there any documentation available with screenshots?
    Regards 
    Prathish Philip

    Dear Bala,
    First, don't give new name to someone. I would prefer Balmukund.
    We are new to cluster, So we are not aware what is the requirements? Our SAN team(EMC2) will do the configuration in SAN, But we have to give the requirement as how many disks should be shared for each servers etc.......Our requirement is as below.
    for optimal performance of SQL, you would be in better position if one drive is given to each file. SAP should have guidelines on the same as it's their product and they would known their IO requirement better.
    We have two servers and we will install SAP on both servers, If first server is down the second server has to automatically take care the application without down time( as per our knowledge we think this is Active/Active cluster).
    This confuses me. You need to check how many SQL Instances they are looking it? Active/Active (I hate you use this term) normally stands for two SQL instances running on two separate nodes. There is nothing shared between them. Uri has explained it in best
    possible way.

  • Siebel Gateway Active/Active Cluster

    Hi, I'd installed before a Siebel gateway in a Active/Passive cluster in the past, but I'm wondering if there is some considerations from the install point of view and if it's supported by Oracle.
    It's supposed to use Sun Cluster Software to build the cluster
    Regards.

    The official answer is no: Active/Active Siebel Server Installation [ID 879472.1]
    For Siebel 8 the Gateway hardly acts as a Gateway anymore.
    Clients connecting are routed directly by the webserver without any action from the Gateway.
    Well, I think the Gateway is still responsible for User Preferences and Siebel Server Configuration, but it doesn't prohibit users from connecting.
    You can see this by shutting down the Gateway in a running (test) Siebel 8 environment and try to connect.
    You do need the Gateway when you want to start a Siebel Application Server.
    For Siebel 8 you won't need big servers for the Gateway.
    So I don't think you are going to gain much from pursuing an Active/Active setup.
    And as the document points out the sizing will probably be the same for Active/Passive and Active/Active.
