ECC6.0 on MSCS issue

Hi,

I am installing ECC6.0 on windows 2008 MSCS clusters. I have completed the below task-

1) ASCS instance

2) MSCS in First Node

While installing Database instance system asked Database Host, I have given Node 1 physical hostname. Whether it is correct or I have to give virtual IP I created for database. Like at the time of First MSCS installation I have given Virtual Instance host for SAP. So, please let me know which Host name shall I give here physical host or virtual host.

My second issue is while installing Additinal MSCS while giving Sap system id, instance number and virtual instance number I am getting "An error occurred attempting to add the 'IND-SAP' node as a possible owner of the 'SAP IIP 00 Instance' resource. Error ID : '5007'. The cluster resource could not be found."

Initially all the cluster resources are in the 1st node then I move all cluster resuces to node 2, but also I am getting same error.

Please help.

Regards,

Sudip

    Hi,

    Please take a note about this:

    1.- During fail over the central services (SCS or/and ASCS, Database) are going to move. CI, DI or ERS are going to stay locally in every Node.

    2.- So, SCS, ASCS and Database are the only installations where you will be using Virtual hostnames and in shared/cluster drive.

    3.- CI, DI and ERS's are installed in Local Drives using Physical Hostnames.

    4.- CI and DI should be using the same system number so when switching from one node to the other, users won´t be disconnected.

    All my MSCS installations are done the same way and fail over works flwalessly, users don´t get disconnected and switch takes around 20 seconds between nodes.

    When fail over takes place, CI or DI will stay up (depending in the Node that goes offline), same happens with ERS's so one Instance is giving service and as ERS is replicated user tx should not lost or disconnected unless timeout occurs.

    Hope this clarifies your questions.

    Regards,

    • Hi,

      I´m sorry for being so late in my responses, I'm doing 2 coworkers jobs because they are on Vacations and doing one EHP5 project also so I´ve being extremely busy this last days.

      1. What will be the Database home in the database instance installation step, As I have two database homes. One in Node 1 and another in Node 2. In the installation I have choosen virtual host name in Database host name filed.

      In both nodes your Oracle_Home will be pointing to local RDBMS installation.

      2. How listener will be configured in a cluster invironment. As we know listener.ora, tnsnames.ora are getting stored in oracle_home and I have again two oracle_home in node 1 and node 2.

      Here is the same, Listener services will be pointing to local drive on each cluster node and yes, listener.ora and tnsnames.ora will be local.

      You install Oracle software in both nodes in local drives, then Database Instance is installed in shared drives, this implies all data files, reorg logs, archive logs, traces, sapbackup, etc.

      Remember you need to do some changes for Oracle Fail safe in the cluster as per the Installation Guide.

    Hi Sudip,

    The virtual hostname should be used during the installation of the Single Point-of-Failure instances, such as ASCS, as per the installation guide.

    Regarding the issue with the resource not found, please, confirm that you've followed the steps from the note below:

    #1490337 - High Availability SAP System on Windows Server 2008 (R2)

    You can refer to section "SAP systems based on SAP NetWeaver 7.0 SR3 and SAP systems based on SAP

    NetWeaver 7.0 EHP1 SR1".

    Also, when you run the command line "cluster.exe res", do you see the resource "SAP IIP 00 Instance"?

    If the issue persists, please, copy and paste the part of 'sapinst_dev.log' which contains the issue and also clarify whether you are using Windows Server 2008 or Windows Server 2008 R2.

    Best Regards,

    Alessandro Parolin

    Hi,

    For database instance you should give virtual host name. Please follow steps from installation guide, all the steps are mentioned there.

    Thanks

    Dear Sudip,

    I am Also stuck in Virtual names during installation of SAP ECC6.0 and MAXDB 7.6 on windows 2008.

    I have following Virtual Names:

    Windows Cluster Group: SAPCLS

    SAP Cluster group( ASCS cluster: ) : SAP AP1 Virtual Name: SAPAP1

    for installing A(SCS) instance we gad used following Command:

    sapinst SAPINST_USE_HOSTNAME=SAPAP1

    with this our ASCS instance was installed successfully and also configured First ASCS installed.

    Now when I started Installing Database Instance for first Host which virtual host mane should I use?

    Should I create Cluster Group for Database Manually and then start ithe installation?

    sapinst SAPINST_USE_HOSTNAME=<NODE1>

    or

    sapinst SAPINST_USE_HOSTNAME=<Virtual hostname of DB>

    or

    sapinst SAPINST_USE_HOSTNAME=<Virtual hostname of Cluster>

    or

    sapinst SAPINST_USE_HOSTNAME=<Virtual hostname of Firts SAP ASCS instance>

    Please Help.

    Regards,

    Ritesh
