Single concurrent user access

Hi all,
I have some data in a database and am about to start to write a simple querying / viewing application (probably Swing/webstart, maybe JSP). Because of the nature of the data, we are only licensed for a single concurrent user, so i have to make sure that not more than one person can use an instance of my app at the same time. Any ideas how i can acheive this?
Many thanks
Alistair

AlistairOkay. Create a facade over all your database related code and then ensure that the database facade class is a singleton class. And all the different threads perform DB access through your database facade class.

  • 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 
    and at a time some 200 to 300 concurrent users access these dashboards pages
    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 number of concurrent users?

    I'm in the process of creating a web site with Cold Fusion and
    Oracle. One concern involves the lack of web hosting services
    that run Oracle on their servers. So, to get around this
    problem, I was considering replicating an Oracle lite database
    and putting it on an ISP's server. My thinking is that there
    would be little need of DBA functions and I can run it on any
    server I choose. But ....
    1. Would Oracle 8i lite support a lot of concurrent users?
    2. What other factors would I have to consider if I set it up
    as a distributed DB ?
    Any help on these thoughts would be greatly appreciated.

  • Concurrent User Limitation

    Hi,
    Understand that VS Studio 2008's CR with a limitation of 3 concurrent user access, am I right?
    How about if I upgrade to CR XI Developer Edition,
    Is there any concurrent user access limitation?
    by using CR Developer XI edition with VS studio 2008, using CR viewer in asp.net web application.
    Thanks

    All versions of CR are limited to 3 CPL. To increase this, you have to go to Crystal Reports Application Server or Business Objects Enterprise.
    Perhaps the better question is; why do you feel you need to go beyond 3 CPL?
    For more info re. Crystal Reports Application Server see the following:

  • Concurrent users unable to open a shared Microsoft Access MDB database

    I have a share on a Cisco NSS2000, the NSS is in Workgroup mode (Firmware 1.13).
    Every user have read/write rights on this share.
    When I try to open an access MDB database from this share it happens that only a single user at time can open the database.
    The second user that try to open the database get a "Cannot lock file" error message.
    So, when a user has the Access DB opened, no-one other can open (or connect to) the same DB.
    It's impossible to open the DB using the access IDE ("Cannot lock file" error message).
    It's impossible to make multiple connection to the DB using OleDB ("Cannot lock file" error message).
    I've tried give full access to the mdb file.
    I've tried give full access to the mdb folder.
    I've even tried to give full access to the temporary LDB file.
    I always get the same error message.
    Is there a workaround?
    Thanks, Max

  • Single concurrent program for multiple operating units

    HI
    I am working on XML/BI publisher to generate AR invoice reports.
    We have single rdf report using which rtf templates are generated.
    There are 10 operating units (10 ORG_ID's) and 10 rtf templates, one for each operating unit. There are 4 different responsibilities for each ORG_ID
    Eg: ORG_ID's = 11, 12, 13, 14..........etc
    Eg: Responsibility = xx, yy, zz...........etc
    I want to register a single concurrent program. When a user submits a request from "XX" responsibility, then the template associated with that org_id should be generated. Whichever responsibility the user is accessing from, that particular template must be shown as output.
    How can i register one concurrent program for multiple operating units.
    Thanks!

    >
    interesting case for 10 OE set 10 template
    what is purpose? for each OE different requirements for layout?
    BTW
    if each Responsibility associated with one org_id then
    - you can get current org_id when you run concurrent program
    - create main template (will be #11) with condition like
    <?choose:?>
    <?when: ORG_ID=11?>
    <?import:xdo://FND.XX11_SUB.en.00/?>
    <?call:TEMPLATE11?>
    <?end when?>
    <?when: ORG_ID=12?>
    <?import:xdo://FND.XX12_SUB.en.00/?>
    <?call:TEMPLATE12?>
    <?end when?>
    <?otherwise:?>
    <?import:xdo://FND.XX21_SUB.en.00/?>
    <?call:TEMPLATE21?>
    <?end otherwise?>
    <?end choose?>so based on org_id will be import of needed subtemplate
    - re-register your "10 rtf templates" as subtemplates
    another way is substitution of template for concurrent then it running
    in before_report trigger set needed template
    l_conc_request_id := fnd_global.conc_request_id;
        if ORG_ID = 11 then
          UPDATE fnd_conc_pp_actions t
             SET t.argument2 = 'XX11'
           where t.concurrent_request_id = l_conc_request_id
             and t.action_type = 6;
      if ORG_ID = 21 then
          UPDATE fnd_conc_pp_actions t
             SET t.argument2 = 'XX21'
           where t.concurrent_request_id = l_conc_request_id
             and t.action_type = 6;

  • A quick question about WebDynpro SLD and R/3 with concurrent users

    Hello ,
    I have a very quick question about Webdynpros and SLD connecting to an R/3 system, when you configure a webdynpro to connect to an R/3 system using SLD, you configure a user name and password from the R/3  for the SLD to use. What I would like to know is when I have concurrent users of my webdynpro, how can I know what one user did in R/3 and what another user did? Is there a way for the users of the web dynpro to use their R/3 credentials so SLD can access the R/3? Like dynamically configuring the SLD for each user?
    - I would like to avoid leaving their their passwords open in the code ( configuring two variable to get the users username and password and use these variables as JCO username and password )
    Thanks Ubergeeks,
    Guy

    Hi Guy
    You will have to use Single Sign On to achieve this. In the destination you have defined to connect to R/3 , there is an option to 'useSSO' instead of userid and password. This will ensure that calls to R/3 will be with the userid that has logged into WAS. You wont need to pass any passwords because  a login ticket is generated from WAS and passed on to R/3. The userid is derived from this ticket.
    For this to happen you will have to maintain a trust relation ship between R/3 and your WAS ,there is detailed documentation of this in help files. Configuration is very straight forward and is easy to perform

  • Retrieving ALL values from a single restricted user property

    How can I retrieve ALL values of a single restricted user property from within
    a .jpf file?
    I want to display a dropdown list within a form in a JSP which should contain
    all the locations listed in the property 'locations'. I ever get just the default
    value when I access the property via
    ProfileWrapper pw = userprofile.getProfileForUser(user);
    Object prop = pw.getProperty("ClockSetup", "Locations");

    Well, the code you've got will retrieve the single value of the property
    for the current user. You're getting the default value because the
    current user doesn't have Locations property set, so the ProfileWrapper
    returns the default value from the property set.
    I assume you want to get the list of available values that you entered
    into the .usr file in Workshop. If so, I've attached a
    SetColorController.jpf, index.jsp, and GeneralInfo.usr (put in
    META-INF/data/userprofiles) I wrote for an example that does just this.
    It uses the PropertySetManagerControl to retrieve the restricted values
    for a property, and the jsp uses data-binding to create a list from that
    pageflow method.
    For a just-jsps solution, you can also use the
    <ps:getRestrictedPropertyValues/> tag. I've attached a setcolor-tags.jsp
    that does the same thing.

  • How to set up reverse proxy to allow user access portal site from internet

    Hi all,
    I have installed 10g(10.1.2.0.2) AS on same machine(single IP for both mid and infra with different users respectively). there is a DMZ on which windows IIS is working through which we need to redirect the request to application server such that users access portal page from internet (within intranet all URLs are working fine). I have went through technet documentation where i found 3 ways : through this link
    http://download.oracle.com/docs/cd/B14099_19/core.1012/b13998/variants.htm
    Section 9.2.1.1, "Configuring OracleAS Web Cache as a Reverse Proxy"
    Section 9.2.1.2, "Configuring the Oracle HTTP Server as a Reverse Proxy"
    Section 9.2.1.3, "Configuring Internet Information Services as a Reverse Proxy"
    I am confused to which option to use. Also i went through the metalink document 270160.1
    Please help me which option to choose to do this.
    Thanks.

    Hi Hozy,
    May be it's too late, I am thinking to go in the same route for our sap portal access to external customers. Please can you share your experience , like what are the challenges have you faced? what is the complexity? what are all the resources we need to configure this?
    I appreciate your feedback.

  • A dynamic Team Planner View to concurrent users

    Hello, I currently have MS Project Professional 2010. Our business is looking into possibly upgrading our system but we need the team planner view in whatever we choose. We currently have hundreds of projects and thousands of tasks linked to resource pool.
    The team planner view is the easiest and fastest view for the business to identify what each person is doing on a particular day, who is helping them, who is working on their project, who is on vacation, etc. Issues we're having right now include:
    1) Project Professional freezes when multiple users try to access the team planner view at the same time. Even after downloading the hotfix package.
    2) We tried uploading some work to Sharepoint but Sharepoint doesn't like tasks with start-to-start predecessors or lag times which greater than 50% of our tasks have.
    3) The printable team planner view prints out hundreds of blank pages between sets of dates. I'm assuming they are "unassigned tasks" and there is no method of removing them. Resource names don't carry over to the second set of dates.
    Is team planner view available in Project Server or the PWA? We're trying to find a way to get this view to everyone. Allow multiple concurrent users to view it at the same time. And to have their view change simultaneously as I change it without having
    to upload or print a new team planner view every time I change something.
    Thanks for the help.

    Thanks for the reply Andrew. We explored using the Resource Assignment View but it had its own set of issues like:
    1) I can assign up to 40 tasks a week to one person, this creates quite a list for each person as the Resource Assignment View lists the tasks in the column under the person's name. A filtered list of one week still creates a long list, 40-50 pages long,
    for 30-40 resources.
    2) Our resources had a hard time finding who was helping them on certain tasks because of this gigantic list. Again, they are unable to access MS Project without freezing the document so they can't open the task and find out who's helping. Therefore, we
    like the condensed Team Planner view.
    I will explore the SSRS report option but from a little light reading, it appears as though this report doesn't automatically update every time I make a change to the schedule. Therefore, I need to manually create a new report everytime I make
    a change to the schedule?
    Thanks Again,

  • Mapping of single Portal users to multiple backend user

    Hello Experts,
    It is possible to map single portal user to the multiple R/3 user? If yes, than what is procedure to achieve it?
    I have a SAP Portal where some users have 2 user ID in ECC, but I need to in Portal the users have only one user ID and password. How can I do to these users can select between their 2 profiles in ECC? Is posible?
    Thanks!
    Regards

    Hi,
    This is not possible since  you would have used SSO to connect to the Backend. Either it is SSO or User Mapping is done, Portal User can only access the Backend with one User ID.
    If you use SSO, for Example if the Portal User is UserA then you would have the UserA in the Backend too. It will use the UserA in backend to access.  (Note: Single User can't access multiple Backend. Since we would have already maintained the Backend Connection details in the System and also in JCo Destination. So it is not possible for a User to access the Backend with two different Backends)
    If you use User Mapping, then you can decide the User which it should use. (For ESS/MSS this is not recommended and it is not feasible too).
