Externalizer in distributed environment

Hi,
Just would like to ask, how can the following situation happen:
Entity MatchSet has attribute setType, which is actually enumeration. It
is stored using externalizer methods. This enumeration implements method
equals so, that exception is thrown when object of another type is passed.
How can the situation like this occur, when within equals method i receive
not enumeration, but db value (Integer) instead? It seems that kodo
infrastructure performs this check at some time, but then the question is
why does it use db value, not actual enumeration value, that should be
retrieved using factory method, as specified in jdo file?

Please supply a stack trace and your metadata.

  • Deploy to Application Server Failed on a distributed environment

    Hi All,
    I am trying to configure new Hyperion verion 11.1.2.2 on distributed environment but during configuring calculation manager to application server failed and getting error message like "Deploy to Application Server Failed". I am not sure what is issue and how to fix it. I have tried to read log files but I am not able to undersantd where to look and debug this issue.
    My Hyperion Environment over view as a below:-
    1- I have used Microsoft VMWARE to build my Hyperion Enviornment
    2- I have created 1 window server 2003 domain and made 4 clients of that domain. (All these systems have windows server 2003 installed). I have given name to each client server i.e. System A, System B, System C, System D
    3- I have installed SQL 2005 and created databases for all Hyperion components i.e. Shared services, calculation manager, epma on a system A
    5- I have installed and configured foundation services and weblogic server on a system B. (In this system I have installed and configured shared services, weblogic, workspace, and able to deploye application server on a same system)
    6- On a system A I am able to complete installation for hyperion Performance Management Architect and Calculation Manager and able to finish all type of configuration for these two components but as soon as system trying to configure any related to APPLICATION SERVER services it fails to configure. On a configuration summary page system shows everything is configured but APPLICATION SERVER says FAILED wrtten on a red color letters.
    I have explored log files and found that Calculation Manager application server failed to deploy or Deploy to Application server failed.....
    Since, I am not sure where to look and how to debug this issue I am requesting to all hyperion friends to help and guide me to debug as I have been trying to install this product since last friday and still no out put....
    I will be really thankful if someone share his or her wisdom to help me....
    Thank you to all in Advance.....
    Thanks,
    Safi

    Did you install all the WebLogic web applications on the foundation machine as well as the machine they are going to be deployed to.
    "On the machine on which you plan to administer the WebLogic Server, you must install all Web applications for all applications you plan to deploy on any machine in the environment. (The WebLogic Administration Server is installed and deployed on the Foundation Services machine.)"

  • Managed to make run EPM 11.1.2.1 in a distributed environment?

    Hi,
    please see blow...
    so far the installation and configuration worked well.
    However, in shared services under the essbase node there are no applications available .
    The same is when I try to priovision a user (for apps).
    Can someone give me a hint how to take a closer look to solfe the problem.
    Evething else seems to work fine. Essbase is up an running and it's accessible via the EAS console.
    Thank you in advance!

    Hi all,
    a more general question:
    Has anybody successfully managed to make run EPM 11.1.2.1 in a distributed environment?
    If yes - please let me know it, just to give me a littel bit of hope.
    I have tried to install and config a EPM 11.1.2.1 like this:
    All Servers Win208R2.
    1. Http and J2EE Server
    2. Essbase Server
    3. Others Server
    4. RDBMS-Server (Repository)
    However the the OPMN process on the essbase server does not start and thus I cannot go the next steps in my install/conifg process.
    Thank you in advance and best Regards.

    Hi Pablo,
    Thanks for your inputs
    - I am a bit familiar with F5's BIG/IP load-balancing methods - round-robin, least connections mode and dynamic ratio - while intelligently supporting session persistence.
    - We can also manage load balancing via the WebLogic Admin console, and as you have noted by the OHS as well - which I am not familiar with...
    This is a newbie question - wouldn't having 3 different agents managing load-balancing complicate things..? As the WebLogic server sits on top of the OHS, I guess they work together to provide load-balancing and configuring the WebLogic for clustering/load-balancing should affect the OHS configuration as well. Is this how it works at the high-level or is it more complicated?
    The EPM System Configurator creates the required cluster and adds servers to the cluster when we deploy the Web applications in the final step of the configuration. So we need not manually configure WebLogic for clustering. But when and where does one configure load-balancing..?
    Thanks again.. Essbase infrastructure is indeed a vast topic as it is interesting... :)

  • Hyperion EPM Installation in a distributed environment...

    Hi all,
    I am planning to install Hyperion products in a distributed environment. I have three machines say, Machine A, Machine B, Machine C. All of the machines have Windows 2003 operating system. And only Machine B and Machine C have Application Server installed. Now I give a brief structure as what machine holds which products-
    Machine A:-
    Oracle 11g
    Essbase Server
    Machine B:-
    Foundation Services- Shared Services
    Essbase Studio
    Essbase Integration Services
    Smart Search
    Administration Services
    Provider Services
    Habnet
    Essbase Client
    Machine C:-
    EPMA
    Planning
    Workspace
    I create a separate database for each component, say, to configure Essbase I have Hyess database, to configure Planning I have Hyplan database.
    And I configure Shared Services to the same database, say, Hyshs from each machine. In that case I just follow the previously congigured database.
    Machine B and Machine C components are deployed to their respective Application Server.
    Can anyone please tell me if this is proper or not? Any kind of modification or recommendation would be appreciated.
    Thanks.

    Hi John,
    thanks for your response. Yes, the Process Manager does not start. I had a look at the Event Viewer. And it shows error and the error properties description is something like this-

    The documentation contains lots of useful information I really think you should study it before even attempting, also take note of the information provided in - http://download.oracle.com/docs/cd/E17236_01/epm.1112/epm_install_11121/ch03s03.html
    For ODI the RCU utility creates the master and work repository, the documentation takes you through the steps or just search on the web as there are a number of installation guides if you trust them.

  • ISE Configuration in Distributed Environment

                      Hi All,
    I have quick questions about  ISE deployment in Distributed environment, as i have purchased 2 X Cisco ise 3395 - For Data Center and 3 X Cisco ISE 3355 for remote location with 3500 Base licences and 500 Advance licences.
    i have some questions on this deployment
    i will install 1 3395 in Primary Datacenter and other 3395 in Our secondary Data center as Primary admin+Primary Monitoring and Secondary Admin+Secondary Monitoring
    and each 3355 will get installed in Remote location as policy server, My Question is it this will be correct deployment?
    or while configuring 3395 do i need to configure Policy server as well in addition to Primary admin and monitoring?
    or please suggest me best deployment stratagy!
    Thanks,
    Sachin

    Thanks for the reply,
    all three sites are connected in MPLS with 100MB redundant band width
    we are have 2 data center one is primary and other is secondary. and all client locations are connected with 100 Meg links where i am planning to install 3355 which will act as authentication server.
    but now my question is
    3395 - Primary Admin+Primary Monitoring - Primary DC
    3395 - Secondary Admin+ Secondary Monitoring - Secondary DC
    3355- will say for one remote location(PSN)
    3355- Second remote Location(PSN)
    3355- third Remote location (PSN)
    thanks,
    Sachin

  • Use of Singleton pattern in Distributed environment

    Can somebody say why it is not advisable to use Singleton pattern for developing client server applications.

    Client-server does not imply distributed environment, IMHO. There are pretty simple C/S architectures where Singleton pattern is not generally a bad thing.
    Distributed environments usually have multiple VMs running, while the singleton pattern typically implemented is a per-VM singleton.

  • Hyperion 11.1.1.3 Installation and Configuration on a Distributed Environ:

    Hi All,
    We have Only Hyperion Production Servers on a Distributed Environment. Now, we are thinking to create new instance that will be called Development Environment and that must be replica or mirror of Prod Environment. For that we cloned Production Servers.
    Since we have all four servers Cloned for Development Environment now I need to Configure those all four instances.....I never worked with installations and configurations ...I do have knowledge and little experience with single tier or one system installation and configuration but distributed environment....I need your support and guideline to configure these boxes...
    Our Distributed Environment lay out is as follows:-
    We have installed Hyperion on Windows Server 2003 and Database is SQL Server
    (1) We have Four Servers
    (a) SQL, which Contains these services EPMA, and IIS Admin Service, World Wide Publishing Services, Hyperion Calc Manager-Web Application,
    Hyperion EPMA (.Net JNI Bridge, Engine Manager, Event Manager, Job Manager, Process Manager, Web Application, and Data Syn-WebApplication)
    (b) Essbase Server Contains these services Hyp ERP Integrator-Web Application, Hyp Essbase Services, Hyp financial Data Quality Management-
    Task Manager
    (c) Planning Server contains these Services Hyp Financial Reporting-Web Application, Hyperion Planning-Web Application, Hyp RMI Registry,
    Hyp Web Analysis-Web Application
    (d) Workspace Server Contains these services Hyp Finacial Reporting (Java RMI Registy, Print Server, Report Server, Scheduler Server), Hyp Foundatio
    OpenLDAP, Hyp foundation shared services-web application, Hyp Provider Services - web application, Hyp Workspace (agent service and web application)
    (2) Now my question is which server needs to be configured 1st then next and next and what things or steps i need to follow for configuration that works fine?
    I know I can run EPMA configure tool for each system from Stat>All program>Oracle EPMA>EPMA Configuration> and then select tool to run.....But I am bit confused that which one go 1st and then next.
    Please give your few words for this so that I can start configure the system....
    I hoping for positive feedback...
    Thanks in Advance.

    We have roughly 8 servers in our distributed prod environment. We are using red linux for everything but the epma and report server which you need a windows server. The way we installed was to start with the base server with Shared services and establish that one and whatever else you want on that server. From there it really didnt matter as you go through the installs it will ask you where your shared services box is located. The only problem we had was that some of our boxes are behind a WHI cage where we had to open up ports. Other then that i really didnt follow a specific sequence of installation after shared services. Hope that helps.

  • Question about Databases on a distributed environment...

    Hi,
    I have quick question. We have production in a distributed environment as follows
    (a) SQL server, EPMA, and Calc Manager
    (b) Workspace, and Shared Services
    (c) Essbase
    (d) Planning
    Now we have multiple databases for each hyperion service i.e.
    (1) HSS (using for hyperion shared service)
    (2) BIPLUS (Using for workspace)
    (3) AAS (Using for Essbase Administrator Services)
    (4) CALCMGR (Using for calculation manager)
    (5) EPMA (Using for EPMA)
    (6) ERPI (Using for ERP Integrator)
    (7) PLANSYS (Using for Planning)
    Now, my question is ....is it necessary that we have that multiple database in a distributed environment or we can have one database for everything? What is main objective for creating databases for each application?
    Please share your best knowledge and give me positive and negative about multiple database and single database for hyperion...
    Thanks to all...
    Safi

    I am going to be lazy and copy an extract from the install doc
    For simplicity and ease of deployment, you can use one database repository for all products (with the exceptions noted below). When you configure multiple products at one time using EPM System Configurator, one database is configured for all selected products.
    Caution!
    To use a different database for each product, perform the “Configure Database” task separately for each product. In some cases you might want to configure separate databases for products. Consider performance, rollback procedures for a single application or product, and disaster recovery plans.
    The following products and product components require unique databases:
    Performance Management Architect interface data source
    Extended Analytics for Financial Management and Extended Analytics for Strategic Finance
    Planning – Each Planning application should have its own repository.
    Performance Scorecard
    FDM – Use an Oracle Database instance exclusively for FDM.
    Data Relationship Management.

    There is a trustsec 2.1 how to guide on cisco's website. There is also a TrustSec 2.0 ISE Guide floating around that has step by step instructions for setting up ISE 1.0.4.

    cursor <> is select * from <> where <> for update of <>, so that it will be locked if it was unlocked...
    but assume i have the following part of code
    cursor <> is select * from <> where <>
    begin
    update the records if some condition is found during runtime
    end;
    and this happens to be invoked in a distributed manner, so what will happen if two sessions run the code at the same time, and how is data integrity handled in this case???
    also explain with regard to usage of sequence(S) in a distributed environment...
    Thanks And Regards,

    Oracle will prevent two transactions from simultaneously modifying a row. Oracle can ensure that the database is consistent.
    Many applications need to enforce a more stringent constraint. They need to ensure that committed data isn't accidentally overwritten by another user.
    Session 1
    SELECT's a value of 5
    Session 2
    SELECT's a value of 5
    UPDATE's the value to 6
    COMMIT's
    Session 1
    UPDATE's the value to 7 <- most applications want to tell User 1 that he is overwriting someone else's changes here
    COMMIT's
    If you have an application where people open a record, work with it for a minute, and then save, there is plenty of opportunity for someone else to change the data before the user saves. Allowing the user to overwrite changes he's never seen is often a bad thing-- the user whose changes were overwritten often gets upset if they have to redo their work.

  • Advantages of installing IOP & EPM in distributed environment

    Hi,
    What are advantages of installing IOP in distributed environment. I refered IOP installation guide and as per instructions, on 1 machine have IOP installation with Foundation service installed while on another machine install Foundation with HSS & other components configured. This is fine but again we need to copy IOP installation directory from IOP machine to EPM machine,in such case what is the advantage of having IOP on different machine.
    Also when we update any settings in properties file like site.properties we need to copy this file to IOP installer on EPM machine which is very difficult to maintain from integrity perspective. In other way we end up having IOP installation on EPM machine.
    Please let me know what are the advantages of installing IOP in distributed environment & what are the cases in which we should ask customer to go ahead with Distributed installation.

    Advantages:
    1.     Multiple users can be defined in the single HSS and can be shared by multiple iop instances hosted on same/different machines.
    2.     All the IOP instances can run independently on their individual JVM
    3.     The centralized EPM server can host services like HSS, OBIEE, Essbase etc.
