  • I have many processes in my usecase , is this normal ?

    - by BugKiller
    Hi, I'm working now on a big system that consists of many subsystems , each subsystem depends on the other. I wrote a usecase for this system , but I note that I have many processes in my usecase ( more than 40 processes ! ) . it looks like this : Group subsystem: add Group. remove Group. join to Group. upload file. create poll. remove file. remove poll. write post/topic close post. edit post. .... Messages Centers send message view inbox read message. and so on .. each user interacts with these processes . How can I reduce the number of these processes? Is it possible to divide the usecase processes into many pages?

  • What is the initiating actor for the usecase shown here

    - by Illep
    I am new to drawing use case and writing use case descriptions. I have an Actor called User , an abstract usecase called Work Type and another use case called Manager. The usecase Manager has a generalized relationship with the Work Type use case. I'm now writing the use case description for Manager use case. And what is the initiating Actor for this use case. Is it the Actor User ? or doesn't it have an initiating Actor ? Note: I only want to know the initiating Actor for the use case Manager

  • Puppet : How to override / redefine outside child class (usecase and example detailled)

    - by alex8657
    The use case i try to illustrate is when to declare some item (eq mysqld service) with a default configuration that could be included on every node (class stripdown in the example, for basenode), and still be able to override this same item in some specific class (eg mysql::server), to be included by specific nodes (eg myserver.local) I illustrated this use case with the example below, where i want to disable mysql service on all nodes, but activate it on a specific node. But of course, Puppet parsing fails because the Service[mysql] is included twice. And of course, class mysql::server bears no relation to be a child of class stripdown Is there a way to override the Service["mysql"], or mark it as the main one, or whatever ? I was thinking about the virtual items and the realize function, but it only permits apply an item multiple times, not to redefine or override. # In stripdown.pp : class stripdown { service {"mysql": enable => "false", ensure => "stopped" } } # In mysql.pp : class mysql::server { service { mysqld: enable => true, ensure => running, hasrestart => true, hasstatus => true, path => "/etc/init.d/mysql", require => Package["mysql-server"], } } # Then nodes in nodes.pp : node basenode { include stripdown } node myserver.local inherits basenode { include mysql::server` # BOOM, fails here because of Service["mysql"] redefinition }

  • Activity tracking usecase for login tracking.

    - by Mdillion
    Creating an activity tracking system for a social site. All user activiti from pooint of login til logoff are to be tracked. This means the first use case is the user's login. Every activity will have the same format so once I figure out how to track one activity then I can create chema for all activities. Currently for login I have steps like: Two solutions I have: Activity 1: User attempts to login Activity 2 A: User has successfully logged in Activity 2 B: User failed to login. Activity 2 B A: User failed to login due to invalid password Activity 2 B B: User failed to login due to locked account. OR Activty 1: User login - with result = Pass or Fail and if Fail reason = flag_id of reason. Accordingly I have to create the schema. For now I have it like this: activity_id object_id (fk) session_id (fk) user_id (fk) flag_id (fk) created_dt friend_id (fk) result (pass/fail) But ofcourse this a work in progress.

  • Usecase for Workflow Engine

    - by Icarus
    Hi, We have an issue where a Database table has to be updated on the status for a particular entity. Presently, its all Java code with a lot of if conditions and an update to the status. I was thinking along lines of using a Workflow engine since there can be multiple flows in future. Is it an overkill to use a Workflow Engine here... where do you draw the line ?

  • Passing values into regex match function

    - by Tim
    In python (it's a Django filter), I'm doing this: lReturn = re.sub(r'\[usecase:([ \w]+)]', r'EXTEND WITH <a href="/usecase/%s/\1/">\1</a>' % pCurrentProjectName, lReturn) I'd like to use a function instead of a string (so I can check that the usercase is a valid name), so it would change to this: def _match_function(matchobj): lMatch = matchobj.group(1) return "EXTEND WITH <a href='/usecase/%s/%s/'>%s</a>" % (pCurrentProjectName, lMatch, lMatch) lReturn = re.sub(r'\[usecase:([ \w]+)]', _match_function, lReturn) How do I get pCurrentProjectName into the _match_function() function?

  • The curious case of SOA Human tasks' automatic completion

    - by Kavitha Srinivasan
    A large south-Asian insurance industry customer using Oracle BPM and SOA ran into this. I have survived this ordeal previously myself but didnt think to blog it then. However, it seems like a good idea to share this knowledge with this reader community and so here goes.. Symptom: A human task (in a SOA/BPEL/BPM process) completes automatically while it should have been assigned to a proper user.There are no stack traces, no related exceptions in the logs. Why: The product is designed to treat human tasks that don't have assignees as one that is eligible for completion. And hence no warning/error messages are recorded in the logs. Usecase variant: A variant of this usecase, where an assignee doesnt exist in the repository is treated as a recoverable error. One can find this in the 'pending recovery' instances in EM and reactivate the task by changing the assignees in the bpm workspace as a process owner /administrator. But back to the usecase when tasks get completed automatically... When: This happens when the users/groups assigned to a task are 'empty' or null. This has been seen only on tasks whose assignees are derived from an assignment expression - ie at runtime an XPath is used to determine who to assign the task to. (This should not happen if task assignees are populated via swim-lane roles.) How to detect this in EM For instances that are auto-completed thus, one will notice in the Audit Trail of such instances, that the 'outcome' of the task is empty. The 'acquired by' element will also show as empty/null. Enabling the oracle.soa.services.workflow.* logger in em should print more verbose messages about this. How to fix this The application code needs two fixes: input to HT: The XSLT/XPath used  to set the task 'assignee' and the process itself should be enhanced to handle nulls better. For eg: if no-data-found, set assignees to alternate value, force default assignees etc. output from HT: Additionally, in the application code, check that the 'outcome' of the HT is not-null. If null, route the task to be performed again after setting the assignee correctly. Beginning PS4FP, one should be able to use 'grab' to route back to the task to fire again. Hope this helps.

  • How long will a "safely stored" Solid-State-Drive (SSD) keep its data? (e.g. bank safety-deposit box)

    - by user31575
    Here's my usecase: once-and-only-once copy off photos/videos to an internal SATA Solid State Drive (SSD) put this drive in a well-ventilated, air-conditioned bank "safety deposit box" for safe keeping The question: How long can I safely store a solid-state-drive in such an environment? i.e. 0% bitrot, 100% success when "plugged in" Are some SSD drives more reliable than other for this usecase? (e.g. smaller size vs larger size, SLC vs MLC, different brands, etc) More fodder: I have read that solid state memory cards (e..g compactflash, or sd cards) have much longer durability than other media (DVD's, CD's, hard drives) for this usecase (guaranteed against bitrot/other dysfunction on the order of ~ a decades vs a year ). I don't know if this applies to "SSD hard drives". Copying to one 500Gb ssd vs 8 64gb flash drives is easier SSD SATA hard drives have no moving parts, but they have more "visible electronics" than a compact flash card. I don't know if this "visible electronics" can fail, i.e. in contr I know many will point to carbonite, other cloud backup stuff, but I like the simplicity of having physical copies and wanted to understand the risks/implications thanks,

  • How to configure XMPP to allow all logged in user to see each other and chat with each other?

    - by Nachiket
    Hello guys, I am new to XMPP. I am using Openfire server, and created a console client using Smack library. My usecase: All users anonymous, logged in (In future, website visitors) will be able to see other anonymous, logged-in users. And they can initiate a private chat (one-to-one) with any of them. So, I am able to logged in as Anonymous user, but I am not able to see other Anon / Logged in users (using Roster), because they are not in anon user's roster. So, What should be configuration OR custom=component/code to to achieve this usecase? Do I need to create server component? Any hint? OR It can be done using proper configuration? Cheers

  • Hosting multiple low traffic websites on ec2

    - by Niko Sams
    We have like 30 websites with almost no traffic (<~10 visits / day) which are currently hosted on a dedicated server. We are evaluating hosting on Amazon EC2 however I'm not sure how to do that properly. One (micro) instance per website is too expensive ~10 websites on one instance (using apache virtual hosts) make auto scaling impossible (or at least difficult) Or is cloud computing not suitable for such a usecase?

  • Problem with authentication from different domains using Django sessions.

    - by Greg
    Hi all, I am developing a bookmarklet which essentially adds a toolbar to a web page user is currently looking at. To use it, user needs to be logged in. To login user clicks on 'Singin' which displays a standard form containing Username, Password etc fields. When user successfully logs in they may chose to navigate to a different web-site. When on another page, they (a) re-load the bookmarklet (b) their session is retrieved from the server (c) user doesn't need to login again. Pretty standard I've would have thought. Using Django sessions and JQuery. I'm having troubles implementing the above usecase. Here are some problems I've encountered: Cross domain POST AJAX requests are disallowed. That was solved with JSONp. I doubt it is a very secure approach but for now it works. My server returns the session id in a cookie, however when the user navigates to a different page I don't really know how to retrieve that session id to send back to my server. Can I even read third party cookies from my JavaScript? I'm looking for some guidelines on implementing the above usecase. Ideally I don't want to redirect user to another page for them to sign in. Any suggestion would be greatly appreciated. Thanks.

  • How can I download Maven artifacts in chef?

    - by recampbell
    I want to do something like this in a chef recipe: maven_artifact "/opt/foo/my.jar" do source "com.foo:my:0.1:jar" end But I can't find a cookbook which provides this. I've written something which basically does this but it doesn't handle snapshots, which requires parsing maven-metadata.xml. Before I plunge into this, I wanted to be sure I wasn't missing something obvious since this seems like a basic usecase.

  • Run script when a specific disk/memory card is mounted under OSX

    - by Max Rydahl Andersen
    How do I run a script when a drive is mounted under OSX ? My usecase is that I would like to automatically copy images from my USB memory/harddrive when it is inserted in my USB card reader, and when a DVD or CD is inserted I would like to copy it for storage in my media center. I've tried using Marcopolo but from what I can see it can only detect the presence of a certain USB device, not the presence of specific harddrive.

  • setCurrentRowWithKey and setCurrentRowWithKeyValue

    - by raghu.yadav
    Good demo demo by shay by shay on how to use setCurrentRowWithKeyValue to synchronize the master and details of same table. Example : Employee master table list and EmployeeDetail form to edit records. However there are many ways to achieve the same usecase. You can use the clicktoEdit property on table row to edit records in place within in table and there is also a feature to show more for few columns in table tools. But objective here is to see how and where and all we can make use of setCurrentRowWithKey and setCurrentRowWithKeyValue. Here is the link about this explains how we can make use of this. link more to be added.

  • ADF Taskflow Reentry-not-allowed and Reentry-allowed

    - by raghu.yadav
    Here is the sample usecase to demonstrate how reentry-not-allowed and reentry-allowed properties works. what doc says about these 2 properties : reentry-allowed: Reentry is allowed on any view activity within the ADF bounded task flow reentry-not-allowed: Reentry of the ADF bounded task flow is not allowed. If you specify reentry-not-allowed on a task flow definition, an end user can still click the browser back button and return to a page within the bounded task flow. However, if the user does anything on the page such as clicking a button, an exception (for example, InvalidTaskFlowReentry) is thrown indicating the bounded task flow was reentered improperly. The actual reentry condition is identified upon the submit of the reentered page. Ingrediants : main.jspx - Jobs_TF - jobs.jspx scenario. click RunTrx button in main.jspx navigates to jobs page by entering into Jobs taskflow. click jobs page back button to navigate back to main.jspx, now click browser back button to navigate jobs.jspx and then click jobs page back Button to see reentry-not-allowed error message.

  • Dynamic Tab Implementation in ADF

    - by Vijay Mohan
    Well, this can be a common usecase across apps to open tabs dynamically at runtime based on the request.Well, in order to achieve this you can have a parent container, lets say a panelTab component.Inside panelTab , u can have a showDetailItem inside an af:foreach or an af:iterator binded to a bean static list which will have as many show detail items as you wish to be shown.something like this.private static List = { new showDetailItem("1"),new ShowDetailItem("2") ...};now in the backing bean you can have a method that takes care of rendering and disclosing an specific tab based on the index.public void openMyTab(){List<MyItems> list = refToParentContainer.getChildren();int indexOfTabToBeOpened = //Write a method that will compute the tab index of the next //tab.list.get(index).setRendered(true);list.get(index).setDisclosed(true);similarly you can set other properties too.}Else, instead of having af:foreach/iterator iterating through the SD items , you can go for static SDs in the page with render property set to false and then you can follow the same approach to render/disclose it at runtime.

  • Common usecases and techniques when integrating a 3rd party application with Oracle Sales Cloud

    - by asantaga
    Over the last year or so I've see a lot of partners migrating and integrate their applications with Oracle Sales Cloud. Interestingly I'd say 60% of the partners use the same set of design patterns over and over again. Most of the time I see that they want to embed their application into Oracle Sales Cloud, within a tab usually, perhaps click on a link to their application (passing some piece of data + credentials) and then within their application update sales cloud again using webservices. Here are some examples of the different use-cases I've seen , and how partners are embedding their applications into Sales Cloud, NB : The following examples use the "Desktop" User Interface rather than the Newer "Simplified User Interface", I'll update the sample application soon but the integration patterns are precisely the same Use Case 1 :  Navigator "Link out" to third party application This is an example of where the developer has added a link to the global navigator and this links out to the 3rd Party Application. Typically one doesn't pass any contextual data with the exception of perhaps user credentials, or better still JWT Token. Techniques Used   Adding Link to Menu Item Using JWT Token in Sales Cloud Use Case 2 : Application Embedded within the Sales Cloud Dashboard Within the Oracle Sales Cloud application there is a tab called "Sales", within this tab its possible to embed a SubTab and embed a iFrame pointing to your application. To do this the developer simply needs to edit the page in customization mode, add the tab and then add the iFrame, simples! The developer can pass credentials/JWT Token and some other pieces of data but not object data (ie the current OpportunityID etc)  Techniques Used Adding a page to the dashboard  Using JWT Token in Sales Cloud  Use Case 3 : Embedding a Tab and Context Linking out from a Sales Cloud object to the 3rd party application In this usecase the developer embeds two components into Oracle Sales Cloud. The first is a SubTab showing summary data to the user (a quote in our case) and then secondly a hyperlink, (although it could be a button) which when clicked navigates the user to the 3rd party application. In this case the developer almost always passes context specific data (i.e. the opportunityId) and a security token (username password combo or JWT Token). The third party application usually takes the data, perhaps queries more data using the Sales Cloud SOAP/WebService interface and then displays the resulting mashup to the user for further processing. When the user has finished their work in the 3rd party application they normally navigate back to Oracle Sales Cloud using what's called a "DeepLink", ie taking them back to the object [opportunity in our case] they came from. This image visually shows a "Happy Path" a user may follow, and combines linking out to an application , webservice calls and deep linking back to Sales Cloud. Techniques Used Extending a SalesCloud application with a custom button Using JWT Token in Sales Cloud Extending Oracle Sales Cloud [Opportnity] with a custom tab exposing External Content Retrieving Data from Oracle Sales cloud using WebServices Coding some groovy script to generate the URLs required (Doc 1571200.1 on MyOracle Support) DeepLinking to specific Oracle Sales Cloud Pages (Doc 1516151.1 on My Oracle Support) Use-Case 4 :  Server Side processing/synchronization This usecase focuses on the Server Side processing of data, in this case synchronizing data. Here the 3rd party application is running on a "timer", e.g. cron or similar, and when triggered it queries data from Oracle Sales Cloud, then it queries data from the 3rd party application, determines the deltas and then inserts the data where required. Specifically here we are calling Oracle Sales Cloud using SOAP/WebServices and the 3rd party application is being communicated to using the REST API, for Oracle Sales Cloud one would use standard JAX-WS WebService calls and for REST one would use the JAX-RS api and perhap the Jackson api for managing JSON objects.. This is a very common use case and one which specifically lends itself to using the Oracle Java Cloud Service as the ideal application server where to host the mediator between the two applications.  Techniques Used Using JWT Token in Sales Cloud Integrating with the Oracle Java Cloud Service Retrieving Data from Oracle Sales cloud using WebServices General Resources The above is just a small set of techniques and use-cases which are used today. There are plenty of other sources of documentation and resources available on the internet but to get you started here are a few of my favourite places  Sales Cloud General Documentation Sales Cloud Customize Tab is useful for general customization of Sales Cloud Sales Cloud Integration Tab focuses on the 3rd party integration techniques  Official Oracle Fusion Developer Relations Blog Official Oracle Fusion Developer Relations YouTube Channel Enjoy integrating!
