Concurrent Users for Query BEx

Hi BW Experts,
my concerns are related to the simultaneous access to a query BEx.
On a total amount of 3000 users I have 300 concurrent users, launching the same query in the same time.
Two are my issues:
1 - how can I test the simultaneous launch of the query without involving 300 persons?
2 - I think the performance of such a test will be not acceptable: what are the levers/parameters BW system gives me to increase these kind of performance?
Thank you in advance for your help!
Kind regards.
Matteo

To have 300 users start the same query at the exact same time is certainly unusual. Don't have any good suggestions on the "Hoe to test" question. This is a difficult question to answer with a short answer.  You have many performance options/considerations:
Are the users running the exact same query with all the same input parameters? Pre-calculated web templates might be of value, this would cache precalculated web pages,  or consider scheduling the query and then distributing the results via e-mail using Information Broadcaster.
If the result set is not unusually large, you may be able to schedule a run of the query and store the results in the OLAP cache, that way the Database does not need to be accessed - the users will get their results from the OLAP Cache (Server memory) which is very fast.
This doesn't even begin to consider the hardware and landscape in place, e.g. are there multiple App servers?
Depending on the approach, your bottleneck could be the DB server, it could be the App Server(s), or specific components of the App server.  A lot depends also on how much you mean that the users run it at the same time - all 300 at exactly the same time, within a 15 minute time period, an hour?
A web query is probably a better approach than the BEx Analyzer (Excel)in this situation as it gnerates  considerably less network traffic.

  • Get the number of concurrent users for a WD application

    Hi all,
    I need to implement a method which counts the number of concurrent users for a Web Dynpro application.
    Say I have a portal with X applications, is there API that can tell me how many users are working on specific application?
    I know that this line of code
    IWDClientUser currentUsers[] = WDClientUser.getClientUsers();
    will get me the number of users that are working on ALL Web Dynpro applications. Is there a way of getting it for specific application?
    I thought of using a text file/small DB table that set/get the number of users but I think it will cause overhead issues.
    Any ideas how to implement it?
    Thanks,
    Omri

    Hi Omri,
    Try using  WDServerState.getActualApplications() method.It returns array of actual running applications.Compare ur application name with the array elements and keep a counter for matching elements.
    String app[]=WDServerState.getActualApplications();
        for(int i=0;i<app.length;i++)
              view.getComponent().getMessageManager().reportSuccess(
               app<i>);

  • How to get Maximum Number of Concurrent users for last few days?

    Hi,
    How I can get maximum number of concurrent users which were logged in to the system (ECC 5.0) I mean I want to check the hostory for last few weeks. Is there any way to get the same? I know that I can get Cumulative number of users in st03 under Expert mode but that is the number of users logged into the system during the day. Is there any place where SAP maintians the High Watermark of Number of concurrent users reached in the system?
    Thanks in advance...
    Regards,
    Pravin

    Sorry I really missed that I have posted a question here on sdn. I wanted to know this for planning the system hardware requirements. Activities like PM ( Performance Management ) happens once a year and during that activity we see heavy user loan on the system so if I have the exact stats of 1 or 2 years data I can size the system better next time. Fortunately last 2 years PM was very smooth for us. In that look for the improvement because each time we had little extra Harware. By doing the exact analysis we can save a Cost of ownership...
    I was looking for R/3 users. I could see the number in st07 but I want to know the exact number at particular time.. I believe that st07 stores only for few days.
    Thanks

  • Load balancing and clustering for SQL SERVER ANALYSIS SERVER instances to access large number of concurrent users for bi site

    HI
    how to do analysis server clustering 
    we have sharepoint bi site and we published many dashboards pointers ,filters kpis

    so for maintain this requirement how we apply clustering for ssas intances 
    and also it has load balancing 
    adil

    Hi Adil,
    According to your description, you want to implement SQL Server Analysis Services Clusster and Analysis Services Load Balancing, right?
    In SSAS, we can design highly available solutions in Analysis Services by using: network load balancing (NLB) technologies, failover clustering technologies, or both. For the details about implemention, please refer to the links below.

  • Max Concurrent Users for Oracle 8i

    Where are you getting the term "Concurrent Users"? Concurrent Users is a term Oracle used to use (or maybe still do) when licensing products. I'm just interested where you are seeing this from.

  • Concurrent Users for BODS designer in TEST environment

    All,
    May I know the best practices for BODS testing ? Would you please share any weblinks for BODS/ETL testing related information ?
    We wanted to access the designer/master/local repository by multi testers in TEST environment. What is typical practice ?
    Does the tester need access to deisgner ? if so, what are main points to be checked/tested in a job design/execution in DS designer?
    Thanks & Regards.

    Hello
    I don't think your testers should have access to the Designer in the test environment.  Why?  Because when you execute jobs in production it won't be via the Designer, so if you execute tests that way it's not a true test.  The execution mechanism (typically the built in scheduler) should be used in the test environments.
    Multiple testers might require a separate local reposity and data areas, however the job server can be shared for functional testing, but not for performance testing.
    Basic good practice for an organisation -
    Project manager scopes a release.
    Developers code in the development enviornment.
    A lead developer packages code (ATL, DDL, etc.) for release candidates.
    Release team (or repsonsible lead developer) promotes code to QA
    Tests performed in QA
    Release team promotes code to production.
    Notes -
    Developers should only have access to the development environment (maybe readonly in QA to aid debugging)
    Testers should only have access to QA
    Operations should only have access to production.
    It takes a bit of work to get your organisation working in this way, but its worth it.

  • Query  (bex) variants

    Hi,
    I've crated a variant for query bex, now I want to execute this query with this variant default setting.
    Moreover, if it's possibile, setting this variant default only for the user xxxx.
    Thanks a lot,
    Alessandro

    It is possible to do it through URLs where the query is called with a variant.
    To do it in BEx, it has to be through workbook or through custom VBA where the query is called with a variant. Haven't tried teh latter but should be possible. Have definately done the former.
    Another thing to explore is using authorizations but if it is for one user, then that won't work too well. Create another query instead, if it critical.
    Cheers

  • Limit the number of concurrent users

    Is it possible to limit the number of concurrent users for the application in Websphere or at the http management level?

    You don't say what version of Websphere you are using, but here's how you might limit the number of sessions in Websphere 4.0 Advanced Edition (other versions may differ):
    Open the Administrative Console. Go down the tree to Nodes, Application Servers and click on the server you want to control (likely Default Server). In the right panel, click on the Services tab. In that panel, click on the Session Manager Service and click the Properties button. That pops up a new dialog.
    Select the Advanced tab here. Put a number in the Maximum in-memory Session Count field and uncheck the Allow Overflow checkbox. Click OK, etc, etc, and you'll probably have to restart Websphere.
    I said "might" because I don't know if this will do what you want or not. Read the help file associated with that dialog and judge for yourself.

  • BEX Query - Run time char InfoObjects manipulation for query results

    Hello Experts,
    Iam working on BEX queries to meet following requirements,
    1)  Display only first 2 char of an InfoObject in the query results. Actual infoprovider has 24 char for this InfoObject. Example: Summary code FABCDXXXX.. But we want to show only 'FA' in query results
    2) We split a 120 char description into two 60 char InfoObjects, we need to concatenate the split char into one for query result display
    3) We need to show a specific hierarchy level, nothing before or after. For example: Eighth level for a cost element hierarchy.
    4) We need to show a constant in a column (which is not there in the table)
    We are planning to use both BEX analyzer and Crystal for the reports.
    I read in one of the thread that we can use formula variables/Customer exit for this but iam not very clear, if you know how to do it or if you have any step by step procedure, can you please pass it to me. Thanks in advance for your help.

  • Query to find out the time used by an user for an application

    Hello All,
    I want to know the query to find out the whole time used by the user for an application. Please view the below data
    Employee:
    SNO EMP_ID EMP_NAME EMP_DATE LOGIN_TIME LOGOUT_TIME
    1 10 Visu 21-Nov-2010 06:30:00 07:30:00
    2 10 Visu 21-Nov-2010 06:40:00 07:20:00
    3 10 Visu 21-Nov-2010 06:50:00 07:50:00
    4 10 Visu 21-Nov-2010 07:30:00 08:30:00
    5 10 Visu 21-Nov-2010 09:30:00 10:30:00
    By checking the above data we can say that the total time Visu used the application is
    8.30 - 6.30 (From 1,2,3,4 records) = 2hrs
    10.30 - 9.30 (Based on 5th rec) = 1hr
    So the total time Visu used the application would be 3 hrs = 180 mins.
    Could you please help me in getting the result from that data using a query?

    Hi Gregor,
    In the note 1149346 that you have mentioned, it says -
    You must start the input-ready query in change mode.
    BEx Analyzer: In the properties of the analysis grid, the switch
    "Suppress new rows" must not be set.  Furthermore,
    the switch "Allow entry of plant values"
    must be set in the local query properties.
    I have not seen this setting Allow entry of plant values in a query - can you tell what is refers to?

    You did not get the question.
    I knew the TCode of the query which I had created using tcode SQ01. user is using this query to see the report
    Like I created query named 'order_line_details'. This query is basically to see the order & other details. To use this by user one TCode'zncv_ord_item'  has been created.
    So in the system lots of query are available. So i want to know the Tcode for those query that are using by user.
