  Hello.
  Complex event processing (CEP) server is a complete product.
  Business Event/event delivery network is just a part of email/event of the SOA Infrastructure component.

  So, if you are interested on the correlation of events from different sources, high performance on the analysis of these events plus operations among the data generated on these events, CEP is your option.
  Hope this helps

• How to aggregate all the events which lead to the occurrence of a complex event?

  Hello
  
  Is it possible to aggregate all of the events that lead to the occurrence of a complex event in this complex event?
  
  Let's say we have six singles events

  id    amount    groupId
  1     1         1 
  2     0         2 
  3     1         1
  4     1         2
  5     2         2
  6     1         1

  The definition of complex event is

  select sum(amount), groupId from myStream[range 20 seconds slide 20 seconds] group by groupId having sum(amount) = 3

  Consider that I have the following class for my complex event:

  public class ComplexEvent {
      private int groupId;
      private int amount;
      private List<SimpleEvent> events;
  
      // getters and setters
      ...
  }

  Is it possible to have two complex events:

  ComplexEvent1 = {groupId=1, amount=3, events=[{id=1, amount=1, groupId=1}, {id=3, amount=1, groupId=1}, {id=6, amount=1, groupId=1}]}
  ComplexEvent2 = {groupId=2, amount=3, events=[{id=2, amount=0, groupId=2}, {id=4, amount=1, groupId=2}, {id=5, amount=2, groupId=2}]}

  How can achieve us?

  Hello

  I blogged an example of solution to this type of use case since it is a common scenario in the CEP applications:

  http://blogs.Oracle.com/CEP/2010/08/enriching_complex_events_with.html

  There are not currently out-of-the-box support for the events of paging to disk storage. If you really more events that can fit into the Java heap, you can try persistent events of the database or a data grid, such that the consistency and by linking to the database or the cache to create the event complex containing the events of causality.

  Another approach is to horizontally partition the flow of incoming events on multiple servers.

  How to create WEB SERVICES in BPEL

  Hi '.

  BPEL and ESB performance.

  It's very big topic I can give you 2 points here

  In BPEL, we must avoid the use of a double variable, is the best way to do this, whenever we create a new variable
  We ask can reuse us adjustable from inside the process, example creating the variable output in activity Invoke
  We must see if we can use an existing variable instead of creating new ones.

  All the associated DB operation must be performed in single composite 1.

  How to create WEB SERVICES in BPEL

  Don't know what you want to ask here, such as BPEL itself is a Web service.

• Can I detect and handle an event already within a structure of the event?

  I have a VI that would do what I want, if I could detect and handle an event of second mouse click while I'm already handling a previous event (selection from popup menu).

  I hope that the picture is clear, but in words what I want is the following: I have first right-click on a chart and select a context menu item, which specifies a graphic manipulation of properties.  Often, this manipulation requires clicking on a second graph to get a reference (for example if I want to copy some of the properties of the first chart on the chart of the target).  It is, it means I'm trying to detect a second event already within a structure of the event.

  I think I could do with a state machine and some registers at offset, and if it's the easiest way, I'll do it.  I would be interested to know whether, if there is a way to detect and manage events 'nested' as I suggested.

  Thank you!

  Your code is not really that complicated.

  Yet, the problem is that confuse you it upward with the main state machine. I would use it in a small parallel loop that only manages events associated with the menu shortcuts. All this should be able to run in parallel in any event, even if the main loop updates the data in the chart at the same time, for example.

  I don't like the dialog box, it hampers the flow of work, but if you use it, use two button dialog so that the user can also cancel if necessary. Instead of the dialog box, you should just temporarily move the cursor on. I also do little to check before operating on the second graph of reason and give a time limit for the second operation.

  Here is a quick project to a more atomic shortcuts Manager. Modify if needed. There are probably bugs.

• Slow computer and the number of processes in the Task Manager

  My dad's computer runs very slow on start up, and when you try to shut down some programs it freezes or just takes its time.  When it freezes, I use the Task Manager to close the program, which usually works.  SE when I had to use Task Manager, I noticed that my father has 53 process running at a time.

  Could it be slow down the computer and if so, what can I do about this problem?

  You can search what process you use cpu on the Task Manager and stop the process.

  Under steps:

  1. right click on the taskbar.

  2. click on the Task Manager.

  3. click on the processes tab.

  4. double-click on the CPU.

  5 is if "system idle process" is max.

  6. If it is not a right click and click on end process.

• Error message: problem loading parameters and check the event log or ask the administrator

  My wallpaper, the desktop icons and most of my documents are gone.

  I have Vista Home Premium and a couple of days and I connected my desktop background was changed. Several desktop icons are missing, and a message came up saying there was a problem loading my settings and check the event log, or ask the administrator (me) for more details. All my "Favorites" were missing in the sidebar and my documents and recorded images folders are empty. Microsoft customer service tells me there is an error in my code for the identification of product (from the Windows Activation in systems and Maintenance) so I can't help out.

  Any thoughts? Thank you!

• Intercept the email opening and closing Email event.

  Hi all
  I created an app that does something, for example showing an alert when an email is opened or when enamel is closed. I am able to show the alert when I receive a call or hang up (via PhoneListener), but the problem is that I am not able to catch open the mail and close the event. I have no idea how this is possible. Please tell me if any APIs exist for this or any other means, it can be done.

  Collate MessageListener and MessageEvent.

• read XML in BPEL and assign values to variables

  Hello
  
  I need to read an xml message in BPEL and assign variables created in the BPEL XML message elements values. What is the best way to do it.

  When you say "' * read an xml message *", the XML comes as input message or you need read the file? "

  If you want to read the file, you can make use of the slot feature.

  Returns the string value of an element defined by lookupXPath in an XML (docURL) given its parent XPath (parentXPath), the XPath (keyXPath) key, and the value of the key (key). Usage: oraext:lookup - xml (docURL as string, parentXPath as string, keyXPath as string, lookupXPath as string, key as String)

  Example: oraext:lookup - xml ("file: / d:/country_data.xml ',' / country/Country ', 'Short', 'FullName', 'UK'") returns the value of the FullName child/country / countries where abbreviation = "UK" in the d:\country_data.xml file

  Thank you
