  • SOA Suite Integration: Part 2: A basic BPEL process

    - by Anthony Shorten
    This is the next in the series about SOA Suite integration with Oracle Utilities Application Framework. One of the first scenarios I am going to illustrate in this series is building a basic BPEL process using Web Service calls to the Oracle Utilities Application Framework. The scenario is this. I will pass in the userid and the BPEL process will call our the AS-User Web Service we created in Part 1. This is just a basic test and illustrate how to import the Web Service into SOA Suite. To use this scenario, you will need access to Oracle SOA Suite, access to a copy of any Oracle Utilities Application Framework based product and Oracle JDeveloper (to build the process). First of all you need to start Oracle JDeveloper and create a new SOA Project to house the BPEL process in. For the purposes of this example I will call the project simpleBPEL and verify that SOA is part of the project. I will select "Composite with BPEL" to denote it as a BPEL process. I can also the same process to create a Mediator or OSB project (refer to the JDeveloper documentation on these technologies). For this example I will use BPEL 1.1 as my specification standard (BPEL 2.0 can also be used if desired). I give the individual BPEL process as simpleBPEL (you can use a different name but I wanted to keep the project and process the same for this example). I will also build a Synchronous BPEL Process as I want a response from the Web Service. I will leave the defaults to save time. I have no have a blank canvas to build my BPEL process against. Note: for simplicity I am going to use as much defaulting as possible. In fact I am not going to specify an input schema for the incoming call as I will use the basic single field used by BPEL as default. The first step is to import the AS-User Web Service into my BPEL project. To do this I use the standard Web Service BPEL component from the Component Palette to import the WSDL into the BPEL project. Now the tricky part (a joke), you drag and drop the component from the Palette onto the right side of the canvas in the Partner Links swim lane. This swim lane is reserved for Partner Links that have a Partner Role (i.e. being called rather than calling). When you drop the Web Service onto the canvas the Create Web Service wizard is invoked to ask for details of the Web Service. At this point you give the BPEL node a name. I have used the name RetrieveUser as a name. I placed the WSDL URL from the XAI Inbound Service screen in the WSDL URL. Once you specify the URL you can press the Find existing WSDL's button to load the information into BPEL from the call. You will notice the Port Type is prefilled with the port from the WSDL. I also suggest that you check copy wsdl and it's dependent artifacts into the project if you intending to work on the BPEL process offline. If you do not check this your target application must be accessible when you work on the BPEL process (that is not always convenient). Note: For the perceptive of you will notice that the URL specified in this example is different to the URL in the last post. The reason is for the demonstrations I shifted to a new server and did not redo all of the past screen captures. If you copy the WSDL into the project you will get an information screen about Localize Files. It is just a confirmation screen. The last confirmation screen is a summary of the partner link (the main tab is locked for editing at this stage). At this stage you have successfully imported the Web Service. To complete the setup of the Web Service you need to set the credentials for the Web Service to use. Refer to the past post on how to do that. Now to use the Web Service. To call the Web Service (as it is just imported not connected to the BPEL process yet), you must add an Invoke action to your BPEL Process. To do this, select Invoke action from the BPEL Constructs zone on the Component Palette and drop it on the edit nodes between the receiveInput and replyOutput nodes This will create an empty Invoke action. You will notice some connectors on the Invoke node. Grab the node closest to your Web Service and drag it to connect the Invoke to your Web Service. This instructs BPEL to use the Invoke to call the Web Service. Once the Invoke action is connected to the Web Service an Edit Invoke edit dialog is displayed. At this point I suggest you name the Invoke node. It is important to name the nodes straightaway and name them appropriately for you to trace the logic. I used InvokeUser as the name in this example. To complete the node configuration you must create Variables to hold the input and output for the call. To do this clock on Automatically Create Input Variable on the Edit Invoke dialog. You will be presented with a default variable name. It uses the node name (that is why it is important to name the node before hitting this button) as a prefix. You can name the variable anything but I usually take the default. Repeat the same for the output variable. You now have a completed node for invoking the service. You have a very basic BPEL process which contains an input, invoke and output node. It is not complete yet though. You need to tell the BPEL process how to pass data from the input to the invoke step and how to take the output from the service call and pass it back to the service. You need to now add an Assign node to assign the input to the Web Service. To do this select Assign activity from BPEL Constructs zone in the Component Palette. Drag and drop the Assign activity between the receiveInput and InvokeUser nodes as you want to pass data between these two nodes. You have now added a new Assign node to your BPEL process Double clicking the node allows you to specify the name of the node. I use AssignUser to describe that I am assigning user data. On the Copy Rules tab you can specify the mapping between the input variable InputVariable/payload/process/input string and the input variable for the Web Service call. We are passing data from the input to BPEL to the relevant input variable on the Web Service. This is simply drag and drop between the two data structures. In the example, I am using the input to pass to the user element in my Web Service as the user is the primary key for the object. The fields become linked (which means data from source will be copied to target). Almost there. You now need to process the output from the Web Service call to the outputVariable of the client call. I have decided to pass back one piece of data, the name associated with the user by concatenating the firstName and lastName elements from the Web Service call. To do this I will use a Transform as it is not just a matter of an Assign action. It is a concatenation operation. This also illustrates how you can use BPEL functionality to transform data from a Web Service call. As with the other components you drag and drop the Transform component to the appropriate place in the BPEL process. In this case we want to transform the output from the Web Service call so we want it after the InvokeUser action and the replyOutput action. The Transform component is actually part of the Oracle Extensions to the BPEL specification. Double clicking the Transform node will allow you to name the node.  In this example I used TransformName. To complete the transform I need to tell the product the source of the transformation and the target of the transform. In the example this is the InvokeUser output variable. I also named the mapper file to TransformName. By clicking the + or pencil icon next to the map I can create the map. The mapping screen is shows the source and target schemas for me to map across. As with the assign I can map the relevant elements. In my example, I first map the firstName from the Web Service to the result element. As I want to concatenate the names, I drop the concat function on the call line. I now attach the last name to the function to indicate the concatenation of the field. By default the names will be concatenated with no space. To make the name legible I add a space between the field by clicking the function and adding a space in the call. I now have a completed mapping. I can now save the whole project as my BPEL process is now complete. As you can see the following happens: We accept input from the client (the userid for the call) in the receiveInput step. We assign that value to the input parameters for the Web Service call in the AssignUser step. We invoke the Web Service call to retrieve the data from the product in the InvokeUser step. We take the output from the InvokeUser step and concatenate the names in the TransformName step. We pass back the data in the replyOutput step. At this point we can deploy the BPEL process to the SOA Suite server. I will not cover this aspect as it really all SOA Suite specific (it is all done via Oracle JDeveloper). Now we need to test the service in SOA Suite. We will use the Fusion Middleware Control test facility. I will assume that credentials have also been setup as per our previous post (else you will get a 401 error). You navigate to the deployed BPEL process within Fusion Middleware Control and select the Test Service option. Specify some test data on the payload at the bottom of the Test Service screen. In my case I am returning my own userid information. On the response tab you will see the result. It works. You can verify the steps using the Audit trace facility on individual calls. As you can see this is a basic BPEL but you get the idea of importing the Web Service is pretty straightforward. You can create more sophisticated BPEL processes using the full facilities in Oracle SOA Suite. I just showed you the basic principals.

  • Attachments in Oracle BPM 11g – Create a BPM Process Instance by passing an Attachment

    - by Venugopal Mangipudi
    Problem Statement: On a recent engagement I had  a requirement where we needed to create BPM instances using a message start event. The challenge was that the instance needed to be created after polling a file location and attaching the picked up file (pdf) as an attachment to the instance. Proposed Solution: I was contemplating using process API to accomplish this,but came up with a solution which involves a BPEL process to pickup the file and send a notification to the BPM process by passing the attachment as a payload. The following are some of the brief steps that were used to build the solution: BPM Process to receive an attachment as part of the payload: The BPM Process is a very simple process which has a Message Start event that accepts the attachment as an argument and a Simple User Task that the user can use to view the attachment (as part of the OOTB attachment panel). The Input payload is based on AttachmentPayload.xsd.  The 3 key elements of the the payload are: <xsd:element name="filename" type="xsd:string"/> <xsd:element name="mimetype" type="xsd:string"/> <xsd:element name="content" type="xsd:base64Binary"/> A screenshot of the Human task data assignment that need to performed to attach the file is provided here. Once the process and the UI project (default generated UI) are deployed to the SOA server, copy the wsdl location of the process service (from EM). This WSDL would be used in the BPEL project to create the Instances in the BPM process after a file is polled. BPEL Process to Poll for File and create instances in the BPM process: For the BPEL process a File adapter was configured as a Read service (File Streaming option and keeping the Schema as Opaque). Once a location and the file pattern to poll are provided the Readservice Partner Link was wired to Invoke the BPEL Process. Also, using the BPM Process WSDL, we can create the Webservice reference and can invoke the start operation. Before we do the assignment for the Invoke operation, a global variable should be created to hold the value of the fileName of the file. The mapping to the global variable can be done on the Receive activity properties (jca.file.FileName).  So for the assign operation before we invoke the BPM process service, we can get the content of the file from the receive input variable and the fileName from the jca.file.FileName property. The mimetype needs to be hard coded to the mime-type of the file: application/pdf (I am still researching ways to derive the mime type as it is not available as part of the jca.file properties).  The screenshot of the BPEL process can be found here and the Assign activity can be found here. The project source can be found at the following location. A sample pdf file to test the project and a screenshot of the BPM Human task screen after the successful creation of the instance can be found here.

  • How can you start a process from asp.net without interfering with the website?

    - by Sem Dendoncker
    Hi, We have an asp.net application that is able to create .air files. To do this we use the following code: System.Diagnostics.Process process = new System.Diagnostics.Process(); //process.StartInfo.FileName = strBatchFile; if (File.Exists(@"C:\Program Files\Java\jre6\bin\java.exe")) { process.StartInfo.FileName = @"C:\Program Files\Java\jre6\bin\java.exe"; } else { process.StartInfo.FileName = @"C:\Program Files (x86)\Java\jre6\bin\java.exe"; } process.StartInfo.Arguments = GetArguments(); process.StartInfo.RedirectStandardOutput = true; process.StartInfo.RedirectStandardError = true; process.StartInfo.UseShellExecute = false; process.PriorityClass = ProcessPriorityClass.Idle; process.Start(); string strOutput = process.StandardOutput.ReadToEnd(); string strError = process.StandardError.ReadToEnd(); HttpContext.Current.Response.Write(strOutput + "<p>" + strError + "</p>"); process.WaitForExit(); Well the problem now is that sometimes the cpu of the server is reaching 100% causing the application to run very slow and even lose sessions (we think this is the problem). Is there any other solution on how to generate air files or run an external process without interfering with the asp.net application? Cheers, M.

  • System Idle Process network traffic?-Updated

    - by Moab
    I was using NetBalancer and noticed network traffic on an unidentified service, but when I highlight it and then go to the lower center pane and click the parent process it says it is the System Idle process, it is showing incoming and outgoing traffic in the upper pane, anyone know why this Windows System Idle Process is talking on the network? Windows 7 HP 64bit . . . Edit, after blocking the traffic for that unidentified Service I checked my event viewer (Windows LogsSystem) and found 3 new events that were never recorded before and matched the time I blocked the traffic. So is this part of the Windows local DNS cache? Event ID 1014 DNS Client Events Name resolution for the name dns.msftncsi.com timed out after none of the configured DNS servers responded. dns.msftncsi.com Name resolution for the name wpad.home timed out after none of the configured DNS servers responded. wpad Name resolution for the name mscrl.microsoft.com timed out after none of the configured DNS servers responded. mscrl.microsoft.com . Then My Web Browser refused to work, I re-enabled the traffic and all returned to normal. .

  • Automatically Kill/Restart Process(es) When Memory is Critically Low

    - by nemesisfixx
    I have a Debian Wheezy VPS box where am running a couple of Django apps in production. Ideally, would have tried addressed my current memory footprint issues by optimizing the apps, adding more RAM or augmenting with Swap. But the problem is that I doubt there's much memory optimization I'd milk from optimizing the Django apps (the stack being open-source and robust), and adding RAM is a cost constraint for me (this is a remote VPS), also, the host doesn't offer options to use Swap! So, in the meantime (as I wait to secure more resources to afford more RAM), I wish to mitigate the scenarios where the server runs out memory so that I just have to request a VPS restart (as in, at that point, I can't even SSH into the box!). So, what I would love in a solution is the ability to detect when a process (or generally, total system memory usage) exceeds a certain critical amount (for now, example the FREE RAM falls to say 10%) - which I've noticed occurs after the VPS's been up for long, and when also traffic is suddenly much to some of the heavy apps (most are just staging apps anyway). So, I wish to be able to kill/restart the offending process(es) - most likely Apache. Which solution when done manually in these situations has restored sane memory usage levels - a hint that possibly one or more of the Django apps has a memory leak? In brief: Monitor overall system RAM usage When FREE RAM falls below a given critical threshold (say below 10%), kill/restart the offending process(es) - or simpler, if we assume from my current log analysis (using linux-dash) that Apache is often the offender, then kill/restart it. Rinse and repeat...

  • iis7 large worker process request queue creating process blocking aspnet.config & machine.config amended (bottleneck)

    - by scott_lotus
    ASP.net 2.0 app .net 2.0 framework IIS7 I am seeing a large queue of "requests" appear under the "worker process" option. State recorded appear to be Authenticate Request and Execute Request Handles more than anything else. I have amended aspnet.config in C:\Windows\Microsoft.NET\Framework64\v2.0.50727 (32 bit path and 64 bit path) to include: maxConcurrentRequestsPerCPU="50000" maxConcurrentThreadsPerCPU="0" requestQueueLimit="50000" I have amended machine.config in C:\Windows\Microsoft.NET\Framework64\v2.0.50727\CONFIG (32 bit and 64 bit path) to include: autoConfig="true" maxIoThreads="100" maxWorkerThreads="100" minIoThreads="50" minWorkerThreads="50" minFreeThreads="176" minLocalRequestFreeThreads="152" Still i get the issue. The issue manifestes itself as a large number of processes in the Worker Process queue. Number of current connections to the website display 500 when this issue occurs. I dont think i have seen concurrent connections over 500 without this issue occurring. Web application slows as the request block. Refreshing the app pool resolves for a while (as expected) as the load is spread between the two pools. Application pool in question FIXED REQUEST have been set to refresh on 50000. Thank you for any help. Scott quick edit to say hmm, my develeopers are telling me the project was built with .net 3.5 framework. Looking at C:\Windows\Microsoft.NET\Framework64\v3.5 there does not appear to be a ASPNET.CONFIG or a MACHINE.CONFIG .... is there a 3.5 equivalent ? after a little searching apparenetly 3.5 uses the 2.0 framework files that 3.5 is missing. So back to the original question , where is my bottleneck ?

  • How can the Private Bytes of a process be significantly less than its effect on the system commit charge?

    - by bacar
    On a 64-bit Windows Server 2003, I can see using taskmgr or process explorer that the total commit charge is around 3.5GB, yet when I sum the Private Bytes consumed by each process (by running pslist -m and adding all values under the Priv column) the total comes in at 1.6GB. I know which process seems to be causing this (sqlservr.exe) as when I kill the process, the commit charge drops dramatically. However the process in question is consuming only ~220MB of Private Bytes yet killing the process drops the commit charge by ~1.6GB. How is this possible? How can the commit charge be so significantly greater than Private Bytes, which should represent the amount of committed memory? If some other factor contributes to the commit charge, what is that factor and how can I view its impact in process explorer? Note: I claim that I understand the difference between reserved and committed memory already: my investigations above relate specifically to Private Bytes which includes only committed memory and excludes reserved memory. the Virtual Size of the process in this case is over 4GB, but this should be irrelevant - Virtual Size in procexp represents reserved, not committed memory, and should not contribute to the commit charge. I'm particularly interested in generalised answers to this question: I'm assuming that if sqlservr.exe can behave in this way, that any process potentially could. Further Investigations I notice that pointing Sysinternals VMMap at this process reports a committed "Private Data" of 1.6GB despite Procexp's reported a Private Bytes of 220MB. This is particularly strange given that the documentation for this field in the "Windows® Sysinternals Administrator's Reference" states that: Private Data memory is memory that is allocated by VirtualAlloc and that is not further handled by the Heap Manager or the .NET runtime, or assigned to the Stack category... VMMap’s definition of “Private Data” is more granular than that of Process Explorer’s “private bytes.” Procexp’s “private bytes” includes all private committed memory belonging to the process. i.e. that VMMap's committed "Private Data" should be smaller than procexp's "Private Bytes". Also, after reading the 'Process committed memory' section of Mark Russinovich's excellent Pushing the Limits of Windows: Virtual Memory, he highlights two cases which won't show up in Private Bytes: File mapping views with copy-on-write semantics (however, according to VMMap there is no significant space allocated to Mapped Files). pagefile-backed virtual memory (however, I tried testlimit with the -l flag as suggested, and no significant memory is consumed by pagefile-backed sections)

  • Tip 13 : Kill a process using C#, from local to remote

    - by StanleyGu
    1. My first choice is always to try System.Diagnostics to kill a process 2. The first choice works very well in killing local processes. I thought the first choice should work for killing remote process too because process.kill() method is overloaded with second argument of machine name. I pass process name plus remote machine name and call the process.kill() method 3. Unfortunately, it gives me error message of "Feature is not supported for remote machines.". Apparently, you can query but not kill a remote process using Process class in System.Diagnostics. The MSDN library document explicitly states that about Process class: Provides access to local and remote processes and enables you to start and stop local system processes. 4. I try my second choice: using System.Management to kill a process running on a remote machine. Make sure add references to System.Management.dll and System.Management.Instrumentation.dll 5. The second choice works very well in killing a remote process. Just need to make sure the account running your program must be configured to have permission to kill a process running on the remote machine.

  • C# - Screenshot of process under Windows Service

    - by Jonathan.Peppers
    We have to run a process from a windows service and get a screenshot from it. We tried the BitBlt and PrintWindow Win32 calls, but both give blank (black) bitmaps. If we run our code from a normal user process, it works just fine. Is this something that is even possible? Or could there be another method to try? Things we tried: Windows service running as Local System, runs process as Local System - screenshot fails Windows service running as Administrator, runs process as Administrator - screenshot fails. Windows application running as user XYZ, runs a process as XYZ - screenshot works with both BitBlt or PrintWindow. Tried checking "Allow service to interact with desktop" from Local System We also noticed that PrintWindow works better for our case, it works if the window is behind another window. For other requirements, both the parent and child processes must be under the same user. We can't really use impersonation from one process to another.

  • What is application and process?

    - by Lu Lu
    An application consists of one or more processes. A process, in the simplest terms, is an executing program. One or more threads run in the context of the process. A thread is the basic unit to which the operating system allocates processor time. A thread can execute any part of the process code, including parts currently being executed by another thread. Source: http://msdn.microsoft.com/en-us/library/ms684841%28VS.85%29.aspx I understand about thread, but I can't distinguish between application & process. What is application? What is process? How do an application have more than 1 process? And please give me an example in C#. Thanks.

  • Spawning Process Never Finishes on ASP.NET Page

    - by Nissan Fan
    The code below spawns the process and sits forever, never finishing. It doesn't matter what process I run. If I use delegates it doesn't work either. It just hangs up in my dev and on the test enviornment. Also, if I use Shell with Wait it does the same thing. If I set wait to false in either approach it works just fine. It's ASP.NET 2.0 VB.NET DotNetNuke 4.0 on Windows Server 2003. I can't even phathom why this would hang up. UPDATE: It causes the CPU to throttle up but it's not running anything.

  • How does Process Explorer enumerate all process names from an XP Guest account?

    - by Joe
    I'm attempting to enumerate all running process EXE names, and have stumbled when attempting this on the XP Guest account. I am able to enumerate all Process IDs using EnumProcesses, but when I attempt OpenProcess with PROCESS_QUERY_INFORMATION Or PROCESS_VM_READ, the function fails. I fired up Process Explorer under the XP Guest account, and it was able to enumerate all process names (though as expected, most other information from processes outside the Guest user-space was not present). So, my question is, how can I duplicate the Process Explorer magic to get the process names of services and other processes running outside the Guest account user-space?

  • bash process uses 90% CPU, comes back on computer restart

    - by Sano
    I’ve replaced the old HDD of my late 2008 unibody MacBook (8 GB of RAM, running OS X 10.7.4) with an OCZ Vertex 3 SSD. After doing this, I've installed Lion and restored my data from a Time Machine backup. Everything is fine, except for a process named “bash” that permanently uses about 90 % CPU. If I kill it via Activity Monitor, everything goes back to normal, but unfortunately the process comes back every time I restart the computer. I've tried do zap the PRAM, reinstall 10.7.4 from the combo package, and even simply wait for more than 2 hours, but the problem is still here.

  • Nohup & Sass: Process keeps running but, after a while, *.scss files do not get compiled

    - by maurits
    I am using Sass on a CentOS 5.8 server and want it to keep running after SSH logout, so that other users can edit *.scss files for days or even weeks to come without any need to start the program each time they login (in fact, they don't even have SSH access). I have used the following command from this question/answer: $ nohup sass --watch path/to/scss/files:path/to/css/output/files & Then, I log out of the SSH session and the process keeps running. It all works fine (logging in again and using touch to create a test file (test.scss) correctly triggers the creation of the corresponding test.css file) for the first few minutes, but after a while the *.scss files stop getting compiled... However, ps aux | grep 'sass' Shows that the process is still running. Anybody knows what am I doing wrong?

  • How to run a process and completely detach it of its parent shell

    - by Bicou
    I'm running a program on a linux server that will take days to complete. I'm launching it from my workstation from an SSH terminal, as this program is command-line only. I want to be able to do all of these : launch that program, redirect standard outputs to files, exit my SSH session without making this terminate the process. I thought about $ ./MyProg.csh -params -foo -bar </dev/null 1>~/out.log 2>~/err.log & However, the process is terminated the moment I close my SSH session. My workstation is running Windows XP, and I cannot guarantee its uptime over several days, which is required for the processing of my data on the Linux server. As you may have noted, my program requires to be launched from CSH. Is it possible to do this ? Thanks.
