Essbase server is hanging due to BSO applications

Hi All,
We upgraded from 9.3.1 to 9.3.3 in august and since then we are having issues. We have about 12 BSO applications, Size is 2GB each. After the upgrade when the users do some operations sucn as rerteval or outline edits etc the essbase hangs and we have to reboot to resolve this issue but after sometime (1 hour later) on performing the same operations it hangs again.
We initially thought it is the server problem, so we migrated all these 12 apps to 3 diferent servers and the other server also started hanging due to these apps. SO this solidifies that there is something wrong in these BSO applications...Any ideas????
System info: Windows environment
sever: windows server 2003
hyp - 9.3.3
Oracle support also jumped in but could not resolve the issue.
Any help would be appreciated.
Thanks!!!

Have a look on Essbase conf file
for netdelay and net recount try increaseing 1000 each and look for diffrence
Also look on avaiable RAM on server. Allot 2 gb per application
let say you have 12 app then 12*2=24 + 6 Gb i.e=30gb so better get 32gb
up to my understanding since ram seq goes 8 ,16, 32, 64
also look at your processor how many core have alloted
Have a read on :http://docs.oracle.com/cd/E17236_01/epm.1112/esb_dbag/frameset.htm?part_optimize.html

  • Server get hang due to JDBC connections

    But I couldn't able to fine any resolution on this problem. If you have any suggestion it will help a lot to resolve it.

    If that is the problem then one obvious solution would be to not spend so much time scrolling through a result set that the pool decides a timeout is in order.

    Hi All,
    I installed Hyperion Essbase 11.1.2.1 on windows xp 32 bit.

    The isssue resolved.
    Reason : At the time of Installation i enabled the "Standalone mode Server"

  • Server got hang while doing FI posting

    Hi experts
    While POSTING THE PAYROLL DOCUMENT (scheduled as a background job in SAP PRDN server), the server got hanged due to some hardware issue and had to switch off.

    We tried to reverse the document, but is it creating "incorrect reversal document".
    Kindly advise us what should we do now.

    Hi,
    if posting has happened incorrectly and values are not in the tables then do this

  • Essbase Server Hangs Intermittently - Urgent pls Help

    Essbase Version - 9.3.3
    Shared Services - 9.3.3
    Enviroment - Windows Server 2003
    We are in the process of migrating the users from Domain A to Domain B
    There are around 15000 users across the board, out of which I assume there are around 250 users accessing the Hyperion Application.
    Since the Domain Migration was started, We encountered Essbase Server freezes Intermittently.
    Essbase Server goes down for about 10-15 Minutes and automatically comes back. No Error Msg in the Essbase Log.
    Active Directory Migration was put on Hold because business had to complete their Month end Activities.
    While we were working to find the RCA and identified that few users who were migrated from Domain A to Domain B appeared to be on Both the Domain and we figured out that it might be one of the reason for Essbase Server Hangs.
    We had a Plan to Run the Update native Directory Utility to clear the Stale Data
    Post Performing the Action our system was stable and didn't had system Hangs.
    we also changed the shared services Cache refresh Interval to 24 Hrs in CSS.xml File ( Just to Make sure the Refresh happens Overnight)
    Since the Active Directory Team had resumed their Migration Activies, we started Experiencing the System Hangs Issues again. server goes down for 5-10 min and comes back up
    Please Input your Valuable Thoughts, Would Really Appreciate your Help.
    Thanks in Advance.

    Hi,
    Thanks for your prompt response.
    As mentioned, AD team have the filters on place, There is no issues with the User Access and there was no change in password after migrating the Domain.
    I have checked the Display Session through Maxl and there is No heavy sessions.
    As Stated earlier, we are unable to identify the cause regarding the System Freeze. All users access the application all  of sudden essbase server hangs and it doesn't allow user to retrieve the data, nor allow him to access any application within Essbase and Planning.
    After 5-10 Min,  server automatically comes back.
    Can you tell me if there is a way to track the system Hangs through Essbase Log without getting the any inputs from the users.
    Assuming if the users sessions are heavy what makes the server hang and automatically resumes without intervention.
    Shared Services Security Log display the following Error, Can you tell me if you had come across any such errors before.
    com.hyperion.css.spi.impl.msad.MSADCacheUpdater.updateUserCache(Ljavax.naming.directory.DirContext;Lcom.hyperion.css.common.CSSNodeImpl;Ljava.lang.String;Ljava.lang.String;Lcom.hyperion.css.datastructures.ProviderCacheMap;Ljava.util.Map;)V(Unknown Source) - Ignoring User.

  • Dimension Number of BSO Application on Essbase

    Hi,
    I'm new in Essbase and I should review an existent BSO application to improve its performance.
    This application has an outline with 5 dimensions, Measure (Account), Period (Time), KPI, Recalculated Market and Organizational Structure. These dimensions have respectively 58,36,4,38 and 5264 total members. I did Measure and Period dimension as Dense dimensions and the others as Sparse Dimension. In this way I will have a block size of 16,3 KB ((58*36)*8) and a number of block of 800128 blocks (5264*38*4).
    This is possible or this organization could create me some problems on performance?
    Should I use ASO application for this? I've read that for financial application with a few dimension BSO applications are good. The application that I discuss before is a financial application of a bank.
    Could someone tell me if the BSO usage is correct?
    Thanks

  • EPMA - Essbase BSO application - UDA problem

    Hi
    we have a shared hierarchy in EPMA which we are using to maintain the Dimensions in the applications.
    Among the dimensions that I need in the Essbase BSO application - two of them have specific UDAs assigned to them. (two for each member in these dimensions - UDAs can be common between the dimensions)
    Dimension_A
    --Member_A1 (UDAx, UDAy)
    --Member_A2 (UDAp,UDAq)
    Dimension_B
    --Member_B1 (UDAx, UDAy)
    --Member_B2 (UDAp, UDAq)
    UDA
    --UDAx
    --UDAy
    --UDAp
    --UDAq
    But when I deploy the application I am only seeing one UDA getting updated into the Essbase Outline (am checking via EAS)
    Dimension_A
    --Member_A1 (UDAx)
    --Member_A2 (UDAp)
    Dimension_B
    --Member_B1 (UDAx)
    --Member_B2 (UDAp)
    I don't know why it is not updating the outline correctly - can anybody suggest what the problem might be ?
    I have tried redeploying multiple times / deleting the dimensions adding them again / even deployed a new application from scratch - no luck.
    Regards
    Ankur

    I tried even in another environment - had the UDA dimension from the Shared Library - and another local dimension.
    Just added multiple UDAs to the same member of the Local dimension and deployed the application - but in the Essbase application it only updated the first UDA that I had assigned to these members.
    For e.g. I added 3 UDAs to
    MemberX : Check1, Check2 & Check 3
    MemberY : Check3, Check1 & Check 2
    But it only updated the first UDA in each
    MemberX : Check1
    MemberY : Check3
    Is there any setting that I am missing ? in EPMA or in Essbase.
    Not sure about EPMA but I don't remember any setting that we need to configure in Essbase for multiple UDAs (it always accepts multiple UDAs)
    Regards
    Ankur

  • Adding Essbase Server access to Planning Application group

    Hi All,
    How we can add Essbase server access to Planning Application group in Shared services ? Pls. advice

    You can't provision access against any application group.
    However, you can create and use native user groups or use external user groups and provision those groups to have acccess to Essbase and Planning.
    See this post for an example of how I like to set up groups in Shared Services for Planning:
    http://camerons-blog-for-essbase-hackers.blogspot.com/2009/08/planning-security-wrong-way-and-right.html
    The top level group I refer to in the post is where I typically grant Essbase Server Access.

  • Cannot Delete / Validate / Deploy Essbase (BSO) application [EPMA]

    Hi All,
    I deployed a Essbase BSO application from EPMA (11.1.2.1) and got a successful result. I have made a minor change and want to deploy the application again but all the options for Duplicate / Delete / Validate / Deploy / Compare are disabled.
    I have tried this on two separate instances with the same result.
    - I have restarted the services already.I also ensured that no ESSSVR service was running when I had shutdown all the services.
    - I have also checked the timeout period to ensure that it is not a timeout issue.
    Does anyone have any clue as to why this might be happening. I was given a suggestion that the Relational Schema for EPMA might have certain flags that may be blocking this. Any ideas on which tables / columns I should look at?
    Shehzad

    First check the application diagnostics to see if anyting is amiss. Go to Application Library, right-click on the application and selecxt "Diagnostics".
    Run all the diagnostics. If a diagnostic test fails, Performance Management Architecxt provides an automated solution or manual steps to resolve the problem. Your security role must be EPMA Administrator to run them. Which also makes me think that it's possible that your security has been changed so you no longer have access to the app. Has someone changed your security? Did you create the app under a different ID?

    If you have moved the server to a new data center and an issue has started occurring then it could point to the change.
    Are you able to log into essbase directly with Maxl using the same account?
    If you run a registry report do you see any of the configuration with IPs instead of DNS/hostname

  • Unable to login into Essbase server

    Hi all,
    I have installed Shared services and Essbase, I did "Externalize Users" in Essbase. It happened successfully. My understanding on this Externalize user is
    "Essbase runs in Shared Services mode and in this mode Essbase create, Edit User permission becomes obsolete. You must be an Essbase administrator to manage users, and you must additionally be a Shared Services administrator to manage users from Shared Services"
    Is this correct please validate. If this is correct, then if you change the password in shared services and sync the native directory in shared services, Essbase should work with new password but this is not happening when i try to connect the Essbase server it is throwing the below error.
    "Error: 1051293: Login fails due to invalid login credentials"
    Is there any other activity that has to be done in this process. I dont have clear idea on this Externalize users can any one explain.
    Can any one help me in this urgent issue.
    Regards,
    Ramachandran J

    Hi All,
    Thanks for the reply. I have few more doubts.
    At the time of configuring the Shared services the default login will be admin and password. But when i configure the Essbase with Shared services in Configuration Utility i had given the different user name as "essadmin".
    So i have followed the following steps to do Externalize users in Essbase:-
    1. Just created the same "essadmin" user in shared services
    2. Done externalize users in Administration services first inside Essbase console, while doing that i have given my own password.
    3. Then went into the specific Essbase server and right clicked security and externalized users there, here also while doing that i have given my own password.
    By doing this step externalize users worked successfully and i can sink the user with shared services.
    Can you let me know whether the above steps are correct or any other procedure is available??
    And i have one more doubt....
    Once externalize users has been done, all the essbase sample database and Analytic services got migrated to Shared services. Then i have created new planning application which reflected in both essbase and shared services.
    Then i loged into shared services and created a new user, then granted only one specific sample application and planning application to that user and sinc with database and also i loged into planning application and refreshed database.
    Then i logged into essbase with the newely created username and password... but i noticed that there is no Essbase server available with the new user login. So i added the same essbase server with "external authentation" ticked.
    Once this is done all the availble application appeared in his login, Here it has Not restricted only to the applicaiton which i have given access to that user, it is showing all the application and also allowing to edit the application.
    I just want to restrict a particular application to one particular user to edit the outline in essbase and this has to be acheived by giving access restriction in shared services.... now i am unable to acheive the same. Can any one help me in doing so???
