What exactly PROCESS BPEL?

Can someone explain what is the difference between the various components of BPEL service, such as BPEL processes, human task, rule business, mediator, what is the meaning of each of them.

Hi '.

BPEL process: This is a web service and inside that we can give the logic to do different things, just as would any Java class, you can interact with DB, write / read a file, interact with queues, interact with other services, BPEL is used in scenarios where you want to integrate 2 system, i.e. the voting for other DB tables and send these data in oracle apps system.
Another scenario is that you have a screen of the user interface, you enter data it argue that the data your BPEL process is called and inside the BPEL, you have a DB adapter that inserts data into the DB table. BPEL is very strong and is the backbone of the Oracle SOA.

Human task: It is a service / a separate application that is called when you need human interaction, assume that inside the BPEL you invoke this human task with details like which your request should go, userid and a few other description, when the BPEL process is called demand goes to this human task, human task has a screen separate UI "BPM worklist. , so when the person enters the work list with his user name and pwd(which you have given in the human task) he can see the demand for him, he can either approve the request of rejection, etc. Do not forget that you have invoked the human task of BPEL so the BPEL will wait for that moment there until the user in the list of work approved / rejected the request and then proceeds

Business rule: They are generally any engine rules that are used to make decisions, such as logical decisions, why one would use business rules that this can be done within BPEL too, because business rules allows a programmer to change the rules, the rules of this trade are used in application where data changes continuously trades , as the Bank, where interest rates changing daily, with business rules business analyst can change the rule and just apply it, you don't need to redeploy the entire application.

Ombudsman: It's SOA 10 G BSE, that serves to integrate 2 services and transfers data between them, more like BPEL, however not as strong as BPEL.

  • What exactly means "charge USEFUL?

    What exactly means "load USEFUL." ??? Please help me with simple examples and the process of BPM.

    Hello
    1. you will have a charge separate for each item in your process. There may be some additional attributues that each task may need. If possible put them all in one single load .xsd file itself. Then use specific fields for a specific task.
    Putting them into word doc will not help with the exception of your documentation. They are all should go into the under your composite/xsd file .xsd file.
    Even if you have the script task, you should always put all fields for this in xsd or xml format only.
    When you build a human task, means that you drag and drop a human task on a process. Then, double click and for the setting and click + to add a new task and this is where give you payload.

    A friendly suggestion is also a large part of the theory will be complicated especially for soa/bpm applications. I would recommend with this understanding you begin practice as with Hello everybody or or simple examples of online. In this way, we can understand both theory and see how this is implemented. I don't want to confuse you with the theory more. Then, start with the actual sample and if you have any questions, then we can take it from there.

    The sample will give about all the details. I don't have any right now. But google around you should find some.

  • What exactly does the Time Machine backup?

    What exactly does the Time Machine backup?

    We have a Mac Pro towers (NOT for sale) and Mac mini with several hard drives installed internally.   Time Machine backup all internal disks or just the boot disk?   This can be configured?

    Time Machine backs up your default boot partition. However, if you have more than one drive or partition on your Mac (and it is formatted in "Mac OS extended (journaled)"), you can set the Time Machine to save these drives too. You can do this by removing these drives from the list of excluded items in System-> Time Machine-> Options... Preferences, so that the next backup will include all internal hard drives or partitions that you want to back up too.

  • What exactly does the "recovery disk"?

    I'm about to reinstall everything on my laptop but would like to know what exactly is the "recovery disk"...

    I presume that it formats the HARD drive with a clean installation of the operating system and all applications toshiba as a CD burner, VAP etc. are NOT installed and must be installed afterwards?

    Well, the restore CD contains an image of Toshiba. Toshiba picture is a package and contains a Windows operating system, the Toshiba drivers, tools and additional software.
    Simply said that it contains everything that you might find preinstalled on the Toshiba laptop.

    And Yes; the recovery CD formats the drive HARD integer (also partitions) and install everything again.
    It redefines the laptop to factory settings

  • The FX - 670 k, what exactly?

    I know that it is mainly a forum for peer-to-peer, but there are some officials in HP lurking around here, so I might as well ask the question:

    What exactly is the difference between the AMD FX - 670 k and an ordinary AMD A10-6700 APU? They have the same exact basic features. Is it simply that the FX - 670 k is unlocked (via the 'k' suffix)? It is even at all unlocked?

    Or it is just an attempt between HP and AMD to obfuscation to make an APU with a processor rather weak power seem more respectable in desktop systems? Because that's what I think, and I would be happy to be refuted that large companies are that cynical.

    Hello Zacabeb,

    The difference between the two is that with the AMD FX - 670 k has removed the HD D 8670.
    You can read a bit more on the difference through the following article

  • What exactly happens when you change the name of the computer, and it asks you to restart?

    What exactly happens when you change the name of the computer, and it asks you to restart - relating to the registration and identification of network?  Specifically when a computer isn't yet in one area but is still in a working group.  Y at - it show any PC by informing other computers it's name has changed?

    Computers into working groups are actively seeking each other, so if you rename a computer, it will not be shown anything. The restart is to erase the name of origin since the system cache, he will think that it's always the old name until the reboot takes place. Work computers is simply 'shake hands' with each other whenever they need to communicate.

    Computers that are part of a domain are created a 'computer' account that is assigned a random password that changes every 30 days by default automatically. These computer accounts work almost identical to an Active Directory user account, which means that they are not proactive they simply cached credentials with their permissions to provide if / when requested by heritage in the environment.
    Users and computers Active Directory accounts are stored in the NTDS. SAID the database, the backbone of an AD environment. When a computer name changes in one area, it takes the PC restarted simply for the PC. The change of name in Active Directory will replicate throughout the environment based on the settings of replication of this environment.
    I'm too simplify all this, but the general concept is there.
  • What exactly should I have?

    Although I'm an addict of the Acer, I just joined the community because I can't find the answer to my question.  I recently bought a Ultrabook through my Government company that had this description of a ultrabook that I intend to get.

    Acer Aspire S7 13.3 in. display 4 GB memory Ultrabook AS2500S1

    • Operating system: Windows 8
    • Processor & memory: I5-3317U processor Intel (1.7 GHz) 2.6 GHz dual-core with Turbo Boost technology; 4 GB memory
    • Storage: 128 GB Solid State Drive
    • Display & Design: 13.3 "CineCrystal HD LED backlit; resolution 1366 x 768; Black finish; Measure 12.8 "W x 8.9" D; 2.65 lbs.

    When I arrived at the unit, he seemed to make the one I ordered, the box showed Aspire S5.  Then I searched this site for and S5 and it will not end.  I tried the AS2500S1 part number and unity, he showed was a V5 with features completely different and sold in another country.  When I search the SKU # 2312983, a mobile phone watch bundle.  Can someone say please 1) what exactly should I? (2) if there are, the S5 is cheaper than what I order?  (3) is there a difference?  Thanks in advance.

    Is what color? I think what the S7 comes color is white and the S5 is black. The S7 is the supermodel for acer. It features a 1920 x 1080 p screen, while the S5 has a 1366 x 768 p display. Also, I don't think that the S5 is a touch screen.

  • What exact HP Laser Jet models are combined with CB518A?

    I have a question about the product Hewlett - Packard P 500-sheet input tray - LJ P401x/P451x Series (CB518A). What exact HP Laser Jet models are combined with CB518A?

    I looked through your website but I couldn't find anything on CB518A. Then I tried Russian/English sites (online markets), but the information differs from one site to the other. I need this information!

    Hey ana banana

    I looked in the paper that you are connected.  The series P4010 mentioned refers to the P4014, P4015 I mentioned above.  It seems that the paper tray is also compatible with the P4510 series which is an improved version of the model P4010.  The P4515 is referenced by instructions P4510 printer.

    So far, these are printers only 3 that I found using this paper tray, however.

  • What EXACTLY should I submit?

    Hmm, a basic question, but I cannot find an answer anywhere -

    When I compile my application with Blackberry JDK, it spits out 3 files: 1 COD (which is in fact a zip of several small COD), JAD 1, 1 JAR.

    Now, what EXACTLY should I submit to App World?

    -the only cod, or

    -the COD and JAD (both of which are compressed in a zip archive?) or

    -cod, JAD and JAR?

    No, you don't need the JAD for App World. But it won't hurt if you include it.

    Simply put, you need not to worry.

    The JAD files are used for OTA downloads (download the application via the browser). You will need to provide this if you download your application to sites like Mobihand, App World does not use OTA, so it is not necessary.

    The JAR file is not necessary for anything. I don't know yet why the compiler produces.

  • BlackBerry smartphones, what exactly is Standby mode?

    In a quest to figure out how to activate the stop screen when I want to, I found the sleep mode, what exactly does.  All the manual says about it is to press mute to switch to standby mode, but does not say anything on this subject.  "Sleep mode", what exactly?  He always give me alerts calendar and phone calls and other alerts, or is he basically disabled?

    Jesse

    The standby mode is just a low power state to conserve battery power. He closed the backlight and screen and does not meet the presses until do you wake. Your notifications, phone calls, etc. are not affected by it.

    The case serves the same purpose: it has a magnet that is detected by the phone to put it to sleep. If you go to the notification / ringtone profile settings, you will notice 2 different setting: off the case and in the case.

  • Cloud of Creative, what exactly?

    I still use PS Elements 6, so I'm late. Cloud of Creative, what exactly? If I want to buy After Effects, I download directly to my computer or access it online from Adobe?

    Creative Cloud applications, including After Effects, install on your PC as all traditional software. The CC Office gives an overview of all available applications. The only difference from the elements, it's that a permit is by subscription rather than a serial number.

    Creative cloud office is free to install and comes with a free storage space.
