High Availability Installation - Help

Hi All,
we are planning for high availabitlity installation for ECC 6.0/oracle 10.2 on HP-UX,
i understand that we need atleast two identical physical machines of HP-UX,
Please help me in below things :
1. link or any document for HA installation (apart from normal inst guide)
2. i have installed ECC 6.0 o HP-UX for dev/qa will the file system remain same for
    HA installation also or what changes required ?
3. Any hints on installation procedure.
    we have only abap engine involved.
Thanking you in advance
All the valid replied will be appreciated and rewarded.
Regards
Naren

Hello,
Here is the link for HA installation : https://websmp209.sap-ag.de/instguides --> SAP NetWeaver --> Installation --> Oracle  --> HP-UX --> ABAP, here you can find everything on HA.
You have to configure your filesystem in cental location, you can not use the same file system as DEV/QA becuase you have not configured the same in HA.
OS level HA configuration will be done by UNIX admin and after that you have to install SAP as per normal procedure only few changes which you can findout if you go thourgh the installation guide.
Cheers,
-Sunil

  • SAP NetWeaver 7.30 High-Availability installation without MSCS

    Hi all,
    Do we have any option to install SAP NetWeaver 7.30 High-Availability System on the third-party cluster solution, except for MS Cluster Service?
    I tried to install the first cluster node without MSCS configuration, however, sapinst.exe checks whether we already set up MSCS on this node, then installer aborted.
    I'd like to know the way to disable this checks. (Or, way to mimic the installer as if MSCS cluster configuration was done.)
    If unavailable, I have to install MSCS first, and SAP NetWeaver, then also have to uninstall MSCS instead of out cluster software;
    It seems to me no sense.
    Best regards,

    Hi Peter,
    Thanks for your quick response.
    It is disappointed for me that HA Installation is tightly combined with MSCS.
    Do we have a way to migrate from other installation scenario to High-Availability?
    For example, once we install ASCS instance as distributed system, then migrate
    it for High-Availability usage, leveraged by profile updates and so on?
    I'm not sure how High-Availability installation is different from other installation
    scenario except for installation path and hostname to be used for connection.
    Best regards,

  • Oracle Version - High Availability Installation

    Hi,
    We are shortly to install SAP on Windows2008/Oracle.
    The DEV and TEST systems are to be installed as stand alone Centralised installations.
    The LIVE system is to be installed as a High Availability system, clustered over two hosts.
    I have questions surrounding the Oracle Editions:
    Looking at the differences between the two Oracle editions in respect to our requirements, Enterprise supports fail-over, whereas Standard does not.
    So,
    Does an SAP high availability installation require Oracle Enterprise Edition to be installed or can it be Oracle Standard Edition?
    Does SAP's High Availability installation functionality handle the complete failover, regardless of Oracle Version?
    Thanks in advance for your assistance.
    Chris

    > Does an SAP high availability installation require Oracle Enterprise Edition to be installed or can it be Oracle Standard Edition?
    SAP systems (also for test and QA)  always require Oracle Enterprise edition. You may get it technically to work with the standard edition but it's not supported:
    Note 105047 - Support for Oracle functions in the SAP environment
    <...>
          56. Standard Edition
        * SAP products always require the Oracle Enterprise edition, using Oracle Standard edition is not permitted.

    HI All,
    I don't have much OBIEE Admin experience, but for a client I have to deploy the OBIEE11g High Availability environment (with cluster,load balancer - http server so on) within a week or so.
    I tried to go thru Oracle's guide on deployment,but seems it'd be helpful, if someone who has already done this kind of job - provides a step by step guide with screenshot etc. Otherwise time is too short for this,

    Hi Srini,
    I also have similar kind of requirement. I have did all the things mentioned in the above Rittmanmead URL. All the things are working fine, but when Primary BI server is down, then I am not able to log in to the application (it is showing authentication failure). In log file of BI Server it is showing below error

  • FIM Portal in High Availability Installation

    Hi Team,
    I am working on something and trying to perform HA in FIM. Below is my current system:
    1) server A and B for SQL DB.
    2) Server C and D for FIM Portal.
    3) Server E for FIM Service.
    4) Server F For FIMSync Service.
    Steps I have performed:
    Installed SQL on server A & B for Every Required DB and done Clustering.
    1) Installed FIMSync service on server F.
    2) Installed FIM Service on Server E.
    3) Installed SharePoint 2010 Foundation server Farm Installation on Server C.
    4) Installed FIM Portal on Server C.
    5) Installed SharePoint 2010 Foundation with same Farm on Server D and FIM Portal as well.
    But when I try to access FIM Portal with Server D's Host name then it is showing error "Service Unavailable".
    Please help !!!!!
    Thanks~ Giriraj Singh Bhamu

    Make sure you have correct SPNs registered and that you have provided correct address of FIMService for FIMPortal. Remember also about delegation needed to be configured.
    SPNs to be registered:
    FIMService/<ServerE> Domain\FIMserviceAccount
    HTTP/<ServerC> Domain\FIMWebAppAccount
    Delegation: FimServiceAccount to FIMserviceAccount and FIMWebAppPoolAccount to FIMServiceAccount.
    "Service Unavailable" is telling you nothing. Examine Eventvwr.
    By the way - this installation hardly seems to be HA - what if your Server E would fail? There is no other server that has FIMService installed. The same for ServerF

  • INSTALLATION ON HIGH AVAILABILITY USING WEBLOGIC SERVER

    Hi All ,
    IHAC where i am planning to propose the following architecture and I did not find much information on the OTN documentation
    How to configure the BI Publisher for High Availability using Oracle Weblogic Server. I have gone thorugh the following document on OTN.
    http://www.oracle.com/technology/products/xml-publisher/docs/BIP_HA.pdf
    1) Can the BI Publisher be installed on a weblogic cluster having two nodes. I did not find any specific information on this in the BI publisher documents other than the link I mentioned above. Do we have any Enterprise Deployment guide for standalone BI Publisher ?
    2) What is the best practice to implement the High Availability of BI Publisher on weblogic server.
    Other info,
    As mentioned in the above link I am planning to use the BIPublisher ultra scalable architecture.
    Where the Load Balancer is HW load balancer and Internal load balancer is managed using the Apache configuration and Oracle XMLDB11.1.0.7 is used as the shared repository.
    regards,
    Pierre .

    Hi
    You have to have a shared drive for CI,SCS abd DB on the shared drive something like SAN.
    You will have HACMP the IBM Cluster SW shall be configured and installed properly.
    You may need support from the AIX engineer to configure it.
    DB and CI installation will be done by Basis normally.
    Yes ,there is arequirement to install and db and OS Filesystems on shared drive.
    For further information ,you can look for inst guide at service.sap.com/instguides
    Hope it helps.

  • Migrating Dimension Server from local installation to High Availability

    Hi Team,
    When Hyperion was installed on the client site (11.1.2.3), there was no requirement for EPMA to become highly available.
    Now that has become a requirement to make it highly available in the event that one of the virtual machine is unreachable.
    In the event that a server becomes unavailable, it is acceptable for a manual failover procedure to be done.
    What steps can be taken to prepare for such an event?
    Possible outcome:
    Configure another dimension server on the second Virtual machine and leave it manually switched off.
    Modify the IIS path to point to a clustered location accessible by both machines.
    In the event of a failover, manually bring up the dimension server on the other machine.
    This is yet to be implemented successfully.

    Remote Desktop/Preferences/Task Server
    Add the FQDN or I.P address of your server in this pane on your book(basically your pointing your book to your installed software on the other machine). Setup your server with the installs you want it to make, and administer it via your book (or any machines with another unlimited ARD) IF you want report generation, you would schedule the clients to send the info to the server. A task server can only do 2 things, install packages or change client settings, thats it.

  • SharePoint Foundation 2013 - Can we use the foundation for intranet portal with high availability ( medium farm)

    Today I had requirement, where we have to use the SharePoint Foundation 2013 (free version) to build an intranet portal ( basic announcement , calendar , department site , document management - only check-in check-out / Version).
     Please help me regarding the license  and size limitations. ( I know the feature comparison of Standard / Enterprise) I just want to know only about the installation process and license.
    6 Server - 2 App / 2 Web / 2 DB cluster ( so total license 6 windows OS license , 2 SQL Server license and Guess no sharepoint licenes)

    Thanks Trevor,
    Is load balance service also comes in free license... So, in that case I can use SharePoint Foundation 2013 version for building a simple Intranet & DMS ( with limited functionality).  And for Workflow and content management we have to write code.
    Windows Network Load Balancing (the NLB feature) is included as part of Windows Server and would offer high availability for traffic bound to the SharePoint servers. WNLB can only associate with up to 4 servers.

    Does that means, that OWAs cannot setup as high avaiable when using standalone OWAs only? Above error appeared when the server OWASrv01 was rebooting.

    Hi Petri,
    For your scenario, you have achieve a  high performance for your Office Web Apps farm but not high availability. 
    For performing a high availability Office Web Apps farm, you can refer to the blog:

  • OIM 11g High Availability Deployment

    Hi Experts,
    I'm deploying OIM 11g in High Available schema, following Oracle docs: http://download.oracle.com/docs/cd/E14571_01/core.1111/e10106/imha.htm#CDEFECJF, I have succesfully installed and configured OIM & SOA in weblogic domain on 'OIMHOST1', trying to propagate the configuration from 'OIMHOST1' to 'OIMHOST2' I have packed (using pack.sh) the domain on 'OIMHOST1' and unpacked (using unpack.sh) it to 'OIMHOST2' so I have updated the NodeManager executing setNMProps.sh and finally Ihave started the NodeManager. In order to Test everything is fine and following the documentation I'm traying to perform the following steps, but I'm not succeed
    I'M MUST TO SAY THAT I'M RUNNING ON SINGLE STANDARD EDITION DB INSTANCE AND NOT RAC AS MENTIONED IN ORACLE DOCS, PLEASE CLARIFY IF RAC IS REQUIRED, FOR NOW I'M IN DEVELOPMENT ENVIRONMENT, SO I THINK RAC IS NOT REQUIRED FOR NOW, PLEASE CLARIFY
    8.9.3.8.3 Start the WLS_SOA2 and WLS_OIM2 Managed Servers on OIMHOST2
    Follow these steps to start the WLS_SOA2 and WLS_OIM2 managed servers on OIMHOST2:
    Stop the WebLogic Administration Server on OIMHOST2. Use the WebLogic Administration Console to stop the Administration Server.
    Start the WebLogic Administration Server on OIMHOST2 using the startWebLogic.sh script under the $DOMAIN_HOME/bin directory. For example:
    /u01/app/oracle/admin/OIM/bin/startWebLogic.sh > /tmp/admin.out 2>1&
    Validate that the WebLogic Administration Server started up successfully by bringing up the WebLogic Administration Console.
    Here its not possible start AdminServer on OIMHOST2, first of all, it looks like boot.properties file under WLS_OIM_DOMAIN_HOME/servers/AdminSever/security is not valid, the first time I try to execute startWeblogic.sh script, it ask for username/password, I have updated boot.properties (vi boot.properties) and manually set clear username and password, this time startWeblogic.sh script passed this stage, but fails:
    <Error> <util.install.help.BuildMasterHelpSet> <BEA-000000> <IOException ioe java.io.IOException: No such file or directory>
    <Error> <oracle.adf.share.config.ADFMDSConfig> <BEA-000000> <MDSConfigurationException encountered in parseADFConfigurationMDS-01330: unable to load MDS configuration document

    MDS-00503: The metadata path "/u01/app/oracle/product/Middleware/user_projects/domains/IDMDomain/sysman/mds" does not contain any valid directories.
    I have verified that this directory "mds" does not exists, as reported by the IOException, in OIMHOST2, but it exists in OIMHOST1. from here its not possible for me following Oracle's documentation, I test this starting Adminserver in OIMHOST1, and starting WLS_SOA2 and WLS_OIM2 managed servers from OIMHOST1 AdminServer console, I have tested 2 ways:
    1.- All managed servers in OIHOST1 are shutdown, for this, managed servers in OIMHOST2 works as expected
    2.- All managed servers in OIMHOST1 are RUNNING, for this, first I have started SOA2 managed server, after that, I have fired OIM2 managed server, when it finish boot process the following message appears in server's output:
    <Warning> <org.quartz.impl.jdbcjobstore.JobStoreCMT> <BEA-000000> <This scheduler instance (servername.domainname1304128390936) is still active but was recovered by another instance in the cluster. This may cause inconsistent behavior.>
    Start the WLS_SOA2 managed server using the WebLogic Administration Console.
    Start the WLS_OIM2 managed server using the WebLogic Administration Console. The WLS_OIM2 managed server must be started after the WLS_SOA2 managed server is started.
    8.9.3.9 Validate the Oracle Identity Manager Instance on OIMHOST2
    Validate the Oracle Identity Manager Server instance on OIMHOST2 by bringing up the Oracle Identity Manager Console using a web browser.
    The URL for the Oracle Identity Manager Console is:

    Hi Vaasu,
    I have succeeded deploying OIM in HA, just now my customer and I are working on the installation of webtier. Now I have a better understand about HA concepts and the way weblogic works -really nice, but little tricky-
    All the magic about HA is configuring properly the network interfaces in each Linux boxes (our case) so, first of all you need to create 2 new floating IP's on each Linux boxes (google: how to create virtual Ip in linux, if you don't know) clone and modify your 'eth0' network script to create the virtual IPs
    Follow the procudere in the HA guide: http://download.oracle.com/docs/cd/E14571_01/core.1111/e10106/imha.htm#CDEFECJF
    create DB schemas with RCU
    install weblogic
    install SOA
    patch SOA
    install IAM
    ---if you are working on a virtual machine is good idea to take a snapshot here---
    Create and configure the weblogic domain (special attentention whe configuring the cluster), see step 13 of 8.9.3.2 Creating and Configuring the WebLogic Domain for OIM and SOA on OIMHOST1, here you need to cofigure:
    For the oim_server1 entry, change the entry to the following values:
    Name: WLS_OIM1
    Listen Address: the IP that is confured in eth0:1 of Linux box1
    Listen Port: 14000
    For the soa_server1 entry, change the entry to the following values:
    Name: WLS_SOA1
    Listen Address: the IP configure on eth0:2 of Linux box1
    Listen Port: 8001
    For the second OIM Server, click Add and supply the following information:
    Name: WLS_OIM2
    Listen Address: the IP configured on eth0:1 of Linux box2
    Listen Port: 14000
    For the second SOA Server, click Add and supply the following information:
    Name: WLS_SOA2
    Listen Address: the IP configured on eth0:2 of Linux box2
    Listen Port: 8001
    Click Next.
    On Step 16 ensure you are using the UNIX tab to configure the machines, also ensure that for machine1 you use the IP configured on the eth0 interface of Linux box1, the same for machine2
    please confirm you have performered 8.9.3.3.2 Update Node Manager on OIMHOST1
    if everything is ok you must be able to start the AdminServer as described in the guide.
    configure OIM: 8.9.3.4.2 Running the Oracle Identity Management Configuration Wizard, in my case I don't need LDAPsync, I have skipped this section, if you configure properly OIM, then you mus perform 8.9.3.5 Post-Configuration Steps for the Managed Servers
    resrtar AdminServer then from the weblogic console, start OIM and SOA if node manager is properly configured SOA and OIM must run properly, update deployment mode and coherence as described in the guide and verify that OIM run perfectly in Linux box1.
    Propagate OIM from Linux box1 to Linux box2 as described in the guide, using pack and unpack (you MUST use the same filesystem directory structure on both Linux boxes)
    Update and start NodeManager as described in the guide
    VERY IMPORTAN OBSERVATION
    the guide say:
    8.9.3.8.3 Start the WLS_SOA2 and WLS_OIM2 Managed Servers on OIMHOST2
    Follow these steps to start the WLS_SOA2 and WLS_OIM2 managed servers on OIMHOST2:
    Stop the WebLogic Administration Server on OIMHOST2. Use the WebLogic Administration Console to stop the Administration Server.
    JUAN OBSERVATION:
    IS NOT POSSIBLE TO START OR STOP ADMINSERVER ON HOST2 SINCE ADMIN SERVER WERE CONFIGURED TO LISTEN ON THE IP ADDRES OF eth0 INTERFACE ON HOST1, SO, ITS NOT POSSIBLE TO PLAY IT ON HOST2, I THINK AND ADDITIONAL PROCEDURE SHOULD BE FOLLOWED TO CONFIGURE ADMINSERVER IN HA IN A ACTIVE-PASSIVE MODE
    Start the WebLogic Administration Server on OIMHOST2 using the startWebLogic.sh script under the $DOMAIN_HOME/bin directory. For example:
    /u01/app/oracle/admin/OIM/bin/startWebLogic.sh > /tmp/admin.out 2>1& -----NOT APPLICABLE
    Validate that the WebLogic Administration Server started up successfully by bringing up the WebLogic Administration Console. -----NOT APPLICABLE
    Start the WLS_SOA2 managed server using the WebLogic Administration Console. ----START SOA2 FROM THE CONSOLE RUNNING ON HOST1, IT DOESN'T MATTER
    Start the WLS_OIM2 managed server using the WebLogic Administration Console. The WLS_OIM2 managed server must be started after the WLS_SOA2 managed server is started. ------ START OIM2 FROM THE CONSOLE RUNNING ON HOST1
    HERE YOU MUST BE ABLE TO LOGIN TO OIM2 SERVER AS DESCRIBED IN THE GUIDE, YOU DON'T NEED TO EXECUTE config.sh SCRIPT THIS SHOULD WORK AS DESCRIBED.
    Server migration should work straight-forward if you have configured the floating IPs as described, I have not configured the persistence yet since my customer does not have the skills to share a storage.
    I hope this helps, and feel free to comment or complement.
    By the way, did you know how to set up a valid SSL certificate in Windows 2003 server??? I need it to test and Exchange 2007 I'm tryin to integrate

  • Running SAP XI in High Availability

    Bonjour a vous tous !
    I am looking for best practices when running SAP Exchange Infrastructure (3.0, well it is now XI 7.0 with the new NW2004s – SP9) in High Availability mode.
    The customer that I work with does not know yet on which platform its production environment will be (Unix/Oracle vs Microsoft/SqlServer 20005). I know that some hardware vendor has built-in HA capabilities, either Software/Hardware based (MSFT MCS, IBM HACMP, etc).
    Should we go for an "SAP XI all-In One" installation or distributed one ?  Should we get one central SLD or one per environment? What is the role of the SLD and Solution Manager? Do they need to be interconnected?
    I have worked with other EAI middlewares (Biztralk Server and webMethods) and normally the Integration Engine sit on it's own server and the various adapters are on their respective servers (i.e.: one server for HTTP, one server for FTP, one server for EJB, etc), since the sizing (RAM. Java heap memory, etc) for all theses adapters are different (FTP a lot of small file, EJB not so many request, but they could eat-up a lot of CPU, etc). Is this a best practice that I can apply also with SAP XI ?
    Thank in advance for you help !
    A+

    Hi Michel,
    Well we seem to work along the same track...
    I am working on 2 customers concurrently - the one using like you using PI 7.0. In their case we implemented a Windows solution using W2K3 Enterprise Edition 64-bit. Avoid 32-bit as it will no longer be supported by SAP next year. We are using MSCS (which is part of the Enterprise Edition by default).
    The 2nd is a solaris customer (very large) for which we are using a cross-data center solution handled by Veritas Cluster Manager with automatic failover between systems and data centers if required.
    Some answers to your questions:
    1. All-in-one - yes
    2. SLD - one for DEV/QA, and separate for Prod - this is recomended by SAP too - I can mail you a guide if needed
    3. With Solution Manager 4.0, it now supports the J2EE side and hence can understand SLDs. The concept is to setup an HA Solution Manager and deploy the SLD for Prod on the same piece of kit.
    4. SAP do not recomend splitting off the Adapter Engine except for specific cases, the main reason being if you have specific systems behind firewalls that you need to communicate with.
    Under no circumstances should you have separate AE's per adapter - this would be an extermely expensive solution hardware and support-wise.
